Complete guide to installing solar panels for mobile home or rvs, van

I have actually picked and also connected the components utilized below as a spending plan variation and as a top quality product. The well-known products have much better resilience, even more guarantee as well as frequently better efficiency. If the price plays a role, you are additionally well offered with the budget variation:


2 x photovoltaic panels, each 100 watts

Renogy Cost controller

2 x spoiler set attachment

1 x Glue Set

1x roofing air duct

2 C4 Y suppliers

1 connection cable 4 mm ø length 6-8 m.

1 battery cable 1.5 m.


I'll describe to you why I chose precisely these parts:.


For the solar modules, I chose a provider that was well rated.

I got 100 watts since I computed it.

For the charge controller, I decided on a branded item and versus a cost-effective item from ebay.com. On the one hand I wished to have the assurance and also on the other hand a screen to see how much electricity I was creating. Furthermore, the charge controller ought to have a get for attaching one more solar module and agm battery (Learn what is really an agm battery here)


I bought both spoiler collections because basic light weight aluminum braces were simply too harmful for me. I don't want the panels to just be swept off my roof covering at 100 km/h and also possibly injure the motorists behind me.

I intentionally purchased the connection wire with a diameter of 6mm. If the cables are too thin, then there is more power loss in the form of warmth. On the one hand I want to avoid the losses as well as on the other hand a possible cable fire. (Extra in the post on cable television cross-sections in mobile homes ).


Installment of the planetary system on the mobile home.

You need to reserve a weekend break for assembly. It took me 2 days to do this. I worked from midday to around 7 p.m. First I built the looters on the panels, then installed the photovoltaic panels on the roofing system and after that connected every little thing. I clarify it carefully below:.


1. Pre-clean the roofing.

The first thing I did was bring a solar panel and also 2 spoilers individually onto the roofing and also try to find the very best position. It is necessary that no shadow falls on it from the roofing framework. I then utilized a pen to map the details so I know where to clean up as well as sand. The very first cleansing action is just about getting rid of the coarse dust. So I just did it with soapy water as well as a sponge and then cleaned the roofing completely dry with a fabric.


2. Prepare the solar spoiler.

In the next action I prepared the looters. These are currently pre-drilled on one side. Initially I had to pierce the holes. I used a 3.5 mm drill for this.

After that I place the first spoiler on a shelf and put the solar component. Since following I had to pierce the holes in the frame of the module. Pre-drilling is very important so that the screws go in well. I made use of the exact same drill bit to drill via the looter into the frame to obtain a mark. Afterwards I removed the looter as well as pierced through the framework.

Sand off the solar spoiler to make sure that they stick well.

Then I screwed the spoilers to the solar modules with the screws provided. The spacers need to go into the spoiler.

Next up was the roofing system. In the area marked for the looter, I roughened the location with the supplied unpleasant fleece. The factor below is not to entirely remove the paint, yet to rough up the surface so that the glue will certainly hold far better. Quite great work at 30 levels as well as sunlight on the roofing system ...

After roughing up, I taped the edges flush with masking tape. This makes it easier to get rid of the excess glue after gluing.

3. Gluing the solar modules onto the mobile home roof covering.

Next, I pre-cleaned the sticky surface areas with spirit and afterwards treated them with the activator/cleaner provided. I made use of a soft, lint-free cloth to do this. Then the entire thing has to blink off for a minimum of 10 mins. After this time, the primer is used, also with a soft, lint-free cloth. Just apply thinly to the splice. At the same time, I additionally used the activator and the guide to the solar looter. The guide should blink off for a minimum of 30 minutes.


After waiting, I glued the very first component. To do this, I transformed it over on the roof covering as well as applied the adhesive, Sikaflex 252, in beads.

After that turn the module over and stick it carefully and properly onto the location marked with covering up tape.

Glue on the solar component very carefully.

After gluing, you have to press the solar module lightly. The adhesive ought to be between 2 and also 3 mm thick between the roofing and also the spoiler. Once you have glued the initial module, continue with the 2nd module.


4. Sticking on a cord duct.

As pointed out over, both modules are linked in parallel with me. This builds up the present and also the voltage stays at 12 V. In the basement I still had a little cord air duct that was 5 cm broad. I placed the C4 Y-adapter in these and attached both modules in it, Cable air duct and Y supplier.


5. Mount the roof air duct on the mobile home.

The cable televisions have to obtain from the solar panels on the roof covering to the batteries in the mobile home in some way. Following I placed the roof air duct. I picked the spot for it near the components and also the former satellite antenna. This permits the wires to find out in our big storage room and I can do excellent circuitry.


The first thing I did was put on the leadthrough, noted it and also roughened the place. Next I pierced an opening in the roof covering utilizing a 23mm hole little bit, Drill the solar roof covering duct with a hole drill, Punctured effectively. Look in the storage room.


After that I glued a little piece of empty pipe into the hole with Dekasil. The pipe extends a little at the top. If a little water somehow gets involved in the roof duct, it does not run straight inwards.


After that I covered up the side with covering up tape, cleansed as well as keyed the surface area and also the roof duct (as currently defined above for the solar module ).


Currently I pulled the cable televisions with and also pressed them to the ideal length. After the needed waiting time, I after that used the Sikaflex as well as glued the bushing on.


Then I secured the two flows of the roofing air duct from the outdoors with Dekasil sealer, considering that both wires were thinner than the rubber seals. I didn't utilize Sikaflex glue due to the fact that I might have to reach the cord once again.


6. Installment and connection of all components of the planetary system.

Openings of the roofing duct secured with Dekasil.

Prior to I wired every little thing up in the following step, I covered the photovoltaic panels with cardboard. As soon as light falls on them, they generate electricity. Because I really did not obtain cleaned and really did not wish to sizzle, covering it up makes a great deal of sense from a security viewpoint!

Cover solar components before setting up the cords as they generate electrical power promptly.

Now it refers discovering an area for the solar controller. I purchased one with a screen so I can constantly see how much electrical energy we were producing. Trick, but nice for us and maybe a little crucial;--RRB-.


The solar controller as a result had to be affixed outside the cabinet and as close as possible to the battery (due to the fact that the cable in between the charge controller and the battery must be as short as possible ). I discovered an area near the seat as well as attached the controller with 4 screws.


There is also a fuse in between the battery as well as the fee controller. If something fails below, you will not refute the whole motorhome. I used a typical automobile fuse (sadly you can not see it quite possibly in the picture), which I can additionally link to my thick booster cable. This sets you back 3 euros on eBay.


After setting up the fuse, I attached the controller to the battery. For this I initially linked both cable televisions to the controller and then the red to the favorable pole of the battery and after that the black to the negative post. This order is essential since negative in autos as well as mobile homes is usually additionally connected to the framework and also you avoid short circuits when linking.


Next I attached the positive lead of the photovoltaic panels to the controller and after that the unfavorable lead. To make it look nicer, I placed the cable televisions in wire air ducts that I still had.


As soon as I removed the cardboard from the solar panels, electricity was created right away as well as the batteries were charged. A really wonderful sensation. As well as this is what the roofing system of our mobile home looks like currently:.


I required about 14 hrs for the full assembly. With this message you can likewise mount your very own solar system completely on your own. If you have any kind of questions, feel free to ask me here in a comment.
