“…The return journey with the solar panels on the roof of my caravan then took us via Riga, Cape Kolka, Ventspils, Liepaja, Palanga to Klaipeda and onto the Curonian Spit to Nida. We then traveled along the Nemunas River to Kaunas and later back home via Poland, always having sufficient solar power.”
Thanks to the solar panels on the caravan, we were able to spend two-thirds of our nights outdoors, at trailheads, on cliffs, and by lakes and rivers. For the remaining third, we used campsites to refill our water tank, empty our waste tanks, and shower. It was another unforgettable adventure – free and independent, powered by solar energy from our caravan.

Dear Mr. Held,
Thank you very much for the friendly contact and the very quick delivery of the ordered solar panel as a complete set including accessories (solar mounting spoiler, roof feed-through and adhesive kit). The solar panel was delivered on Friday around noon, so I was able to mount the panel on my caravan on Saturday according to the instructions.
Since I had no further help, I had to mount the solar panel myself and modified or adapted your instructions slightly.
First, I drilled the 4,5 mm holes in the two SOLARA spoilers for the solar panel. Using these holes as a guide, I transferred the necessary 3,5 mm drill holes to the panel frame and drilled them. Additionally, I drilled a total of 5 holes along the lower long sides of the panel frame, spaced 15 to 20 cm apart, to attach the solar cable and MC4 solar connectors with cable ties.
I covered the surface of the solar panel with cardboard to protect it during further assembly and to prevent it from generating electricity.
Then I placed the module at the selected location and transferred the edges of the roof penetration and the spoilers onto the roof using a felt-tip pen.
Next came the sanding, cleaning and priming of all adhesive surfaces on the module, the roof penetration and on the roof itself.
Contrary to your instructions, I applied the adhesive directly to the caravan roof and only then placed the module in the desired position.
For this, I used an air mattress. I inflated it slightly, folded it once, and placed it centrally under the solar panel. By carefully releasing air, the panel could be positioned very precisely in the desired location. After pressing the solar panel down slightly and removing the remaining air from the mattress, it could be easily pulled out from under the panel.
Now the cable gland was placed in position, secured with adhesive tape, and then all adhesive edges were carefully smoothed with a damp finger.
I left it under the carport for 24 hours. Then, on Sunday, I tested it extensively.
I already had a PWR regulator from Schaudt, the LR 1218, connected to the Schaudt Elektroblock CSV 409 as a solar charge controller and operated a mobile, foldable 100 Wp solar panel via it.
The auxiliary battery is a LITH-110 12,8V lithium iron phosphate storage battery with 110 Ah. Therefore, a maximum of 220 Wp of solar panels can be connected to the solar charge controller.
The Solara S480M36 module achieved a daily yield of 32 amps (from 22 A – 20% to 54 A – 49% battery charge level). This performance matches your specifications.
Next on the agenda is replacing the solar charge controller with a Victron Energy BlueSolar 75/15 MPPT controller and a Bluetooth dongle, which I also received from SOLARA. Thanks again and best regards.
