Off-grid Camping with a tent-trailer (Combi Camp). How to set solar system?

Thanks for Gijs’s shared why he choose solar power and how it installed the solar panel on his tenttrailer Combi Camp. The following is his experience.

I started thinking about a good solution to be able to camp “self-sufficient” two years ago. I had several reasons for doing this:

1. Prices for electricity on campsites are very high in my opinion and this is a waste of money for a tap, a light and charging a telephone and / or tablet (in my experience this is between € 2.50 and sometimes € 5.50 per day). : S
2. The most beautiful places on campsites are usually without electricity and you are not among the caravans and campers;)
3. It is just very easy and convenient (no mess with (extension) cords anymore) B)

All my sets are 1pc Lensun 60w flexible solar panel, 1pc Lensun 55w flexible solar panel, 20A MPPT solar controller, 55Ah battery, fuse and 12v car plugs

I have been using Lensun flexible solar panel forover two years now. This allows me and my family to camp fully off-grid.

I explained how I connected this installation. This setup provides power for several items:
1. LED lights
2. Watertap
3. USB chargingports (smartphones/tablets/laptop)
4. Universal 12V car output

Solarpanel setup:
Lensun Semi-flexible 60Watt panel
Strapped in an aluminum frame, so it can be placed in a sunny spot:

Additional I added a Lensun 55W 12V Black ETFE Flexible Solar Panel Special size. It fit perfectly on the storage compartment infront of the trailer of my Combi Camp

The semi-flexible panel is glued on with Sikaflex and finished off with silicone sealant.

Both panels are connected to a EPSolar Tracer 2215BN which charges and regulates an Optima Yellow Top 55Ah battery.

All is connected to a fuse box to divide all the different items mentioned before

Over Landing With Solar Power

   Thanks for Joey’s review. He have some Lensun slar panels, a 80w flexible solar panel installed on the FJ hood, a 100w foldable solar panel and a 10W solar phone charge, the following is his review of these solar panels.

“I have used many products made by Lensun. I have an 80W flexible mounted to my FJ Cruiser that charges my second battery which powers my fridge/freezer and keeps it going. I also have the 100W folding all weather solar charger which charges the batteries on my off-road trailer giving me lighting, charging station for cell phones, Garmin and water pumps. I recently have acquired their folding 10w cell phone charger.

Their products are high quality. The charge is excellent. They withstand any weather you throw at them and they will last for many years.  I highly recommend their products and will not consider another brand now that I have had such a good experience with the company and their products.”

The following article is from Joey’s website, about why he installed solar panel on his Toyota FJ and how he did it. (original link

Overlanding with Solar Power

  As I was driving down the road with the sunlight beaming down upon my rig, I couldn’t help but think how I could be harnessing some of this energy and transforming it into power in order to be able to go out in the middle of nowhere and camp where I want to, without having to PAY for an electrical site at some park somewhere. The whole goal and idea of overlanding to me was to get out where there is nobody and see things that most people do not see and do things that most people are not able to do.

  If we just go from park to park we are seeing the norm, what everyone else sees and does and we really do not get to experience overlanding to the fullest. We are just park hoppers. So I wanted to make myself as self-sufficient as possible, being able to survive comfortably without the need for outside intervention for periods of time.

  So there are several things to consider. Water was my first one. I have to have a shower. I have to be able to drink, brush my teeth, clean clothes and dishes. Power was the next one. As some of us here may be backpackers where we can put everything we need on our backs, we are here to speak of the overlanding experience. So we all have a vehicle of some kind. That vehicle has a battery and plug ins where we are able to charge everything we can think of in one way or another.

  BUT, the last thing we want to do is to spend 3 days out in the middle of nowhere, reaching that destination of “going where no man has gone before” and living life without any interference of human resources and then we go to pack up and our vehicle will not start because we have drained the battery down to nothing from charging all of our necessities. So how do we keep from this? What are our options?

  So back to my original thought while driving down the road, thinking about these things, and wondering what do I need to do to be able to be completely self-sufficient power-wise and harness this energy so that I can power all the things I have at my disposal in order to be a comfortable as possible and enjoy this overlanding experience to the fullest?

  I considered and began to research solar. I had experience with solar before. I have backpacked and I had the small solar charger that clipped onto my pack and as I hiked across the earth, the sun would beam down giving it a charge and then I could throughout the day keep my GPS or cell phone charged. What I needed now was on a much bigger scale. But I still like the idea…

The solar power’s benefits are out there and hold true for most people.

1. It gives us freedom to get out where most people are not able to go.
2. It is quiet. I like quiet. One of the main reasons I want to get away is to get away from the noise I have to deal with every day.
3. It is easy. It requires very little maintenance and no fuel.
4. Even though there is cost to purchase, if you live long enough and go out enough you will eventually make that money back in savings.

Before you get into “is solar right for me?” or “should I use a generator?” you need to determine the answers to a few questions.

1. How often am I going to be doing this? Am I going to be full-time, a couple times a year, multiple times a year?
2. How long am I going to stay at a time? What is the longest I am going to stay without having contact with civilization?
3. What gear do I need to run? Lights, fridge/freezer, fan, charging cell phones and games (and other stuff we should leave at home because we do this to get away from regular life)
4. Noise…some people do not like noise. In the middle of nowhere and you are sitting by the fire at night and you are either listening to the coyotes, crickets and owls and other night crawlers, or you’re listening to a Briggs and Stratton purr on all cylinders.
5. How much do I want to spend? Almost everyone has a budget. Unless you are independently wealthy, you have so much money you have budgeted for each item you want to put into your build according to necessity and need. WANT has a little to do with it if you are into how “cool” or “impressive” your rig is going to be to others. But don’t build your rig so “cool” that you have to get jumpstarted every time your group gets ready to leave because you run everything off of your single car battery.

Is it for me?

1. Weekend Warrior – A couple times a year for weekends. You are really a weekend warrior. There is nothing wrong with that. People joke and kid about you but you get out when you can. We can only do what we can WHEN we can and you take every opportunity to make the best of the time you have.
2. Solar is probably not going to be a big deal to you and it could take years to recoup your investment in a solar power system for your rig.
(1) You can most likely keep all of your food in a cooler and there is no need for a fridge/freezer.
(2) You can keep your devices (cell phone, tablets, GPS, etc.) charged via your 12v car charger ports.
(3) Your lights can run off of batteries.
3. But what you might want to look into is:
(1) Rechargeable or solar things such as lights and lanterns
(2) Solar lighting around the camp

4. Overlander or Boondocker – If you plan to go out quite frequently or if this is your “thing” in life and what you love to do and you see yourself not only going out when you can get off work on the weekends, and maybe you plan some vacations that will include getting “off grid” for several days or weeks at a time, solar would be beneficial for you.
  Staying in parks that charge $15-30 a night would add up quickly. Most parks offer spots with hookups and then spots that are labeled as “tent camping” or “primitive.” There is a big difference in price per night if you have to have electricity and water.

5. What you need to look into is:
(1) Rechargeable or solar lights and lanterns (for example the collapsible solar lights or LUCI lights ($20 each at or the AAA battery powered lights offered by ENO which are $20 for a whole string of 10’
(2) Solar panels (many different varieties, sizes, wattages and mounts) like those found from Lensun Solar (
(3) Dual Battery System for your rig that can be charged by your solar panels
(4) Solar Generator or “Portable Power” such as those offered by Goal Zero in many different options.

How Much?

   Compared to those people who spend $50k to 250k on an RV and then $30-50 a night in a full service campsite (I often think how in the world they can afford some of these rigs), we really do not have that much invested. But to us who work day to day jobs and live paycheck to paycheck it’s a small fortune. And if most of our wives found out just how much we had in our rigs we would be calling a lawyer instead of 4 Wheel Parts for our next purchase.

   But we must decide if Solar Power makes sense for us. It’s kind of like sushi, it’s not for everybody. But for some of us, it is really a necessity and will make it where we can bring and enjoy many of the comforts of home and not need any outside sources to do so.

Basic Parts of an Overland Solar System

1. Solar Panels
(1) Solar panels come in various sizes and wattage.
You can get them from a small wallet size all the way up to 3’x5’
(2) Wattage will depend upon size and can range from 5W up to 100W and several panels can be coupled together to increase wattage.
2. Make Up
(1 ) Polycrystalline – most popular and the best price
(2) Monocrystalline – more efficient but higher priced
(3) TFSC – Thin Film Solar Cell – less efficient but can be made into different shapes.
3. Charge Controller
(1) A charge controller sits between an energy source (panels) and the place where the energy is stored (battery or power source).
(2) The controller prevents overcharging by limiting the amount and rate of charge to your batteries and protects against drainage by shutting down if stored power falls below 50 percent capacity.
4. Inverter
(1) This turns the low-wattage DC power produced by Solar Panels and stored in batteries into AC power.
(2) Power Station – this is much like a generator but solar charged batteries power your equipment and supplies. The Power Station is hooked directly to the solar panels which charge the power station. Then you can use the power station as a generator.
5. Storage
(1) Vehicle Battery or 2nd battery
(2) Power Source

Example Solar Panel Systems & Costs

Renogy 200W           2          200W            30 Amp Renogy        N/A            $464

Lensun 80W             1           80W              Lensun 10A              N/A            $209

GoPower Electric    1           170W                30A             GoPower 1500W   $1600

Zamp Solar 480W    3         480W                 30A   Zamp           N/A            $2000

Goal Zero 150           1       Folding 150W      N/A                 Yeti 150           $449

NOTE – The Goal Zero kit listed last would not be connected directly to your vehicle power source but to the Yeti 150 Power Station.

The Math

Ok, so let’s go back to 7th grade and put all of this into a word problem and try and make this make sense and see if it is worth it to us. When thinking about energy savings of going solar, we must think in terms of whether it would be comparable to what we would spend using a gas generator. This is totally ruling out the sound co-efficient and just crunching numbers.

An Average generator burned one ½ gallon of gas per hour. If we round around and say that the average price of gas is $2.50 then being parked for 8 (normal time we would run it at night for lights and fans) hours we would spend $10 per night.

Based on that figure, if you have $1000 investment that you have made on solar, you would reach a breaking even point on that investment in 100 days. So how many days per year do you go out and need this type of charging system? If your solar system allows you to avoid $40-50 per night campground fees, then your break-even point would come much sooner.

After you reach that break-even point then your energy costs would be $0, other than what you would pay for replacement or broken parts such as batteries.

For me

I researched and looked around to see what was best to fit my needs. To be honest I put more investing into this presentation than I did my research back then but I think I made the right choice and it has been worth every penny.

I spent $200 on Ebay for the Lensun 80W solar Combo that came with a charge controller. I like Ebay because sometimes they run discount codes pretty often. I wasn’t in a hurry so I waited on the 15% off day. It was a flexible panel that is black and came with all of the cables needed to hook it up to a second battery. I planned to install the panel permanently on the hood of my FJ Cruiser where I had painted the hood black. It was the perfect size and would hardly be noticeable. I also purchased a Heavy Duty Dual Battery Auxiliary Isolator with 15’ and 4’ cables for $112 on Ebay. This is a necessity when using dual batteries and came with the heavy duty cables that I needed to hook everything together.

I went to the local HS welding shop and had them fabricate me a battery stand out of heavy metal. They measured and it took them about 30 minutes to come up with a stand with rails that would fit directly into the slot I had made for it behind my air cleaner, passenger side by the fire wall. They charged me $5 for the materials.

I bought 4 grade 8 bolts at the local Ace Hardware store for $6 with lock washers and washers in order to install the battery plate. This took about 30 minutes to drill the holes, insert the bolts and install. After this I went down to the local Advanced Auto Parts store and purchased their deep cycle battery for $109 and a battery holder for $9. I installed the battery and holder in about 10 minutes and tightened everything down.

I installed the isolator on the driver side and ran wires connecting it to the second battery and also to the alternator. A switch was installed inside the cab for me to push if I wanted to use the alternator to charge the second battery. Otherwise all of the charge would come from it sitting using the solar panel.

I had to purchase windshield water relocators because the solar panel being added to the hood covered up the OEM windshield washers. These were $8 at advanced. I used heavy duty double-sided tape and 4 self-tapping screws to attach my solar panel to the hood. I used double sided tape to attach the charge controller to the top of my sealed intake and ran wires from the solar panel and 2nd battery to the charge controller. It was done.

Total Cost – $435

I added up that I will spend (estimated) 60 days/nights in my tent this year. With an average of $10 per night running a generator the cost would be $600 for an 8-hour night plus the cost of a generator (around $800) totaling $1400. That leaves me with after 1 year a savings of $965 not counting the cost of staying in parks where it would cost an average of $40 per night.

How do you set your offroad/overland vehicles solar system? Why you need solar powered?

Paul installed 3pcs Lensun flexible solar panel (50W, 30W, 20W) on his offroad vehicle Nissan Xterra roof and hood.

Click link to shop

The following are some questions we returned to him about the use of solar panels, and how he seted the off grid solar system on his car.

Why he installed solar panels in his car, and what convenience does solar powered bring to his life.

Lensun: hi Paul, many thanks for your puchased, how’s did you connect the solar panel?

Paul: Solar panels are hook to the redarc bcdc controller, Alternator takes over when the car is started. The system is all run off the battery and solar panels what you’re looking at in the picture is not hooked to the car at all, but through the bcdc controller to the front battery. (the front battery is the car primary battery, the back battery is the 2nd battery)

Front is controlled by the bcdc controller has two separate systems. Front battery is its own system, back battery has its own system, they do not share at all.  But by alternator, when I go out camping or I use a lot more power I hook up more solar panels and lay them on the ground.

The following is the front battery(car primary battery)

I just took it right now and it’s dark outside, this is the monitoring system that I put in for it, this is just the secondary battery, top solar panel give to the battery, second refrigerator, 3rd AC power, 4th DC power.

Lensun: So the car battery is charged by alternator and the solar panel charge the 2nd battery?

Paul: Yes, except Redarc bcdc solar is always charging according to redarc. Solar panels are only for the 2nd back battery,  the hook up to the front battery from the bcdc controller,  it’s only so it can see the alternator.

Hate to say it, but the 2pcs 100 foldable panels are Renogy I lay out when we go camping. Supposedly this is supposed to be there high end model,  it’s fading bending,  and looks like crap,  it’s only in the few days a month sun.

Lensun: how do you installed the flexible solar panel on the car roof? 

Paul: I screwed them on the sides, and made a little platform for the back, so I could screw it in, and then just use silicone on sides, cuz I remember the wind would pull it up some in the heat.

That’s real world pictures not cleaned just walked out at lunch, and took the pictures you want me to I wash them, they probably not been washed in over 3 months right there.

Nothing is underneath them to seal them under, I just put the screws and then seal around the sides, so I can remove them really easy.

I drove around for a few days with just the bolts and the heat cause them to come up a little bit so that’s why I put the seal around the sides.

Lensun: hi Paul, many thanks for your reply. could you tell us whats this black board under the solar panel, is it a aluminum board, pcb board or others?

Paul: ABS plastic really heavy duty good stuff, Really thin does not bend that easy weather’s really well.

Lensun: hi Paul, total Lensun 110w flexible solar panel, is it enough for you to use? did you check how many amp they produce perday?

Paul: It works perfect, when it is over a hundred degrees outside refrigerator comes on a lot more than regular, so I usually lay out a hundred Watt on the ground,  and if we’re out camping I have a total of 2pcs 100w on the ground, and the 110w on car family of 4pcs,  so they like there Electronics. The battery can support 340 watts.

Most I’ve seen come in is around 15 amps, the bcdc controller can support 40 amps, and the battery can support and Max of 25 amps, so round 310 works out well,  when on camping and driving around in daily use 110 works fine,  now park for a few days if it’s really really hot, I have to lay out 100 Watts more.

The two I lay on the ground are Renogy 100 Watts each,  wife got them for me gift,  they’re hard to take care of though,  so flimsy and cheap made and fading and bending.

Lensun: how many watt of your fridge? is it 12v?

Paul: When it’s on it pulls around 5 amps. I run it at about 33 degrees. It’s the ARB 37 I think. I have the 50 but it was too big for my vehicle

Lensun: the back 85amp battery only power the fridge or power other electronice devices too?

Paul: It Powers everything,Inside the vehicle,I have USB plugs cigarette lighters.
Two surge protectors 1500 watt sine inverter used for pumps to air up flotation devices, when we go to the lake, believe it’s used to run a coffee machine when we go camping, and a lot of other things.

Lensun: do you think the solar is a must for you? we found most of the people do not install solar panel on their offroad vehicles or have a foldable solar panel.

Paul: For me yes, I love it,  I run a refrigerator sometimes,  I bring a TV, sometimes I bring the PS4 for the kids,  it makes coffee in the morning, phone chargers all depends on the situation.

If we’re at the lake,  I need air pumps,  if I’m camping sometimes my lights go out,  I need to charge them, Bluetooth speakers need charging,  I can go on and on how much I need it

With the refrigerator in the vehicle,  it also works great when you’re picking up the kids from school,  you don’t need to stop by the gas station,  and spend $15 on snacks,  just go to grocery store and put it in the fridge, Lunchables Gatorades Waters sodas are a must for kids, gas station runs get expensive.

Without the solar panels, I couldn’t run the refrigerator or anything else, most vehicle batteries die with a cell phone charging for few hours.

Lensun: many thanks. How do people charge the 2nd battery if they do not have solar panel?

Paul: They tie the batteries together the alternator is not smart enough, when done that way to charge both batteries. The back battery will die. You could try to use a battery isolator, but most newer cars have a smart alternator and only see the front battery, so when the front battery is full, it will also see the back battery as full, and just trickle charge it.

Lensun: but the alternator only work when the car drive, but the car does not always drive.

Paul: Yep so you have to have solar. That’s why I have solar. I sit in my car, and watch movies waiting for the wife sometimes in the grocery store. All my kids are practicing baseball or softball. I sit in the car and watch movies. Don’t have to waste gas with the car running.

Here’s another pic from a while back, I was going sleeping on the beach for two nights,  ended up just sleeping in the vehicle, so I set my vehicle up this way. Sheets were not on the foam mattresses at the time of picture.

If you go camping in the wild and don’t have solar panel,  there’s really no reason to bring a second battery it’s going to die so fast.

Lensun: Most people camping in the camp park, for example Kampgrounds of America, Good Sam Club… etc, people can get electronic there.

Paul: So if they go to a plug up one and pay the extra,  you wouldn’t need a battery they have power outlets at those campsites. I don’t like those, because too many people are around. Feel like I’m in a parking lot with trees growing out of it too many people around.

Lensun: so installed solar panel solved the problem of outdoor power, no need to worry about the battery is dead.

Paul: Yeah, I don’t have to worry about power,  my battery sits and float mode a lot even, when I am charging like 3 or 4 cell phones and speakers plugged in, and running a tablet on Wi-Fi, why the kids watch a movie no more dead battery.
Now at night you got to watch what type of fan to run, so you don’t kill your battery in the morning. Most small USB fans are fine you can actually run two or three of those at night.
Most tablets will last the night without even being charged, then the next day you can charge while you’re swimming.

Lensun: What do you think of the hood heat effect the solar panel’s output, did you test it? 

Paul: I live in Texas that Sun is hot here, there’s no car engine going to going to get as hot as that sun.

The solar panel that I lay on the ground we’ll get 170 +, the one on my hood we’ll get 170 +, not sure if it’s affecting. I’m sure it is but I don’t worry about it, I would just add another solar panel somewhere.

You would be really surprised with the heat shield underneath the hood,  it’s just as hot in the Sun on top of your hood as the same as your trunk, they make the heat shields on vehicles under the hood they actually work. I’m sure it’s affecting it, mine’s been on there while and it works great.

If your engine gets around 200 degrees in Texas, it’s almost 200 degrees on your back trunk. Engine heat not really affecting it in my opinion, those heat shields under the hood work pretty well.

When I got into the solar, and putting all the electronics in my car.  I bought a heat gun, so I could take temperatures, I was worried about the redarc controller overheating.

Lensun: so did you test the temperatures?

Paul: The ones on the roof we’re getting round 170 and the ones on the hood was getting around 170 and the ones on the ground we’re getting around a 170.

Lensun: so the hood’s temperaturer is almost same as the car’s roof, back trunk?

Paul: Yeah it really does not affect as much as people think.

Hood Flexible Solar Panel

Most off-road vehicles have a second battery that powers the refrigerator and other electronic devices. When the engine is running the 2nd battery is charged from the alternator but isolated when the engine is off.

The summers are very hot and if the vehicle is parked for a few days with the fridge running you risk draining the battery. While at a campsite, you can put out a portable solar panel. However, when parked in other locations you need a permanently affixed solar panel that wouldn’t get stolen.

Most of the off-road vehicles roof has a luggage rack and needs to be loaded with luggage, so can not install solar panel on the roof. Its a good choice for install the solar panel in the flat hood.

The following is our customers installation cases.

1. Lensun 80W Black flexible solar panel installed on Toyata FJ Cruiser, to keep the electronics safely running off the battery when the FJ is sitting.

Installing a Lensun ETFE Flexible Solar Panel on a Fiberglass Hightop

Thanks Robert share us his installation experience of Lensun flexible solar panel.

This is the origian link of Robert’s web

Solar electrical systems are found on many RVs and camper vans. I have had a portable panel that I could deploy while camping, but in our most recent video we show how I went about installing a Lensun ETFE flexible solar panel on a fiberglass hightop.

Hightops are wonderful options in camper vans and Class B RVs as they make the rig much more comfortable. One of the challenges that they introduce, however, is that it is more difficult to mount solar panels to the roof. This is particularly true if the fiberglass hightop is not reinforced with wood ribs to provide a strong point to secure the panels.

The fiberglass hightop on my conversion van camper is not reinforced, and it is curved everywhere. There is literally not a single flat spot on the hightop roof. I was also unable to find an “off the shelf” roof rack that would clear the hightop which left me with the options of custom fabricating a roof rack or installing flexible solar panels that would conform to the curve of the roof.

Lensun ETFE Flexible Solar Panel
Lensun reached out to me about the same time that I was starting to shop for a panel to see if I would be interested in trying their new ETFE flexible solar panel. Since I was actively looking for a flexible panel, and Lensun is a brand that I had heard good things about during my research, I agreed to accept a flexible solar panel to test and review.

ETFE is the new flexible solar panel technology (as opposed to the older PET technology). ETFE panels feature a stronger, fiberglass back sheet, greater efficiency, increased corrosion resistance and temperature range, and improved resistance to dirt and dust buildup. On top of all these benefits, the ETFE panels are more attractive (at least in my opinion).

Installing a Flexible Solar Panel on a Fiberglass Hightop

There are several options for attaching flexible solar panels to the roof of a vehicle. One option is to bolt them down to a roof rack (if one is installed or available for the vehicle). Popular options for installing flexible solar panels to fiberglass or rubber roofs include using VHB tape or Eternabond tape. We went a similar, but slightly different, route with our installation.

Our friend, Glenn, did quite a bit of testing with different products to secure flexible solar panels to the fiberglass roof of his van three years ago. His recommendation was Dual Lock Reclosable Fastener from 3M. If you are not familiar with this product, think of an industrial strength Velcro only different (Dual Lock utilizes a bunch of mushroom-shaped tabs that lock together). The stuff is incredible strong – and it comes apart should the panel ever need to be removed.

As an added layer of security, I also applied a strip of 4″ Eternabond tape to the leading edge of the flexible solar panel. It is the leading edge that will lift and fail first so this extra precautionary step allows me more peace of mind while driving down the highway.

I have had this flexible solar panel installed for several weeks now and have been pleased with the performance. Everything is working as it should and the panel is reliably putting out power all day every day.

“Hi Alice ..
I have 2x22ah backup batteries that I charge using the solar panels.. this is to keep my ARB fridge in the car powered for a few days..and also charge some electronics and laptop.
I also have a normal charger 220volt and can charge these backup batteries with my car alternator as well.
The solar panels act as a backup and make the car look good as well 🙂
I will run a full test next week when I am back from a business trip
