Proof That Actually Matter

I own a 2023 Thor Gemini motorhome. Since purchasing it, I have not been able to spend a night boondocking because the battery didn't have enough power even to run the fridge overnight.
I contacted Adam about installing Lithium batteries and upgrading my 50-watt solar panel. He came up with a plan, answered dozens of my questions, and in 4 days installed the new setup.
I could not be happier with the results and with Adam and his team's attention to detail.
If you are looking for solution to a similar problem you need not look any further than to Adam and his team at Avalon RV

Very satisfied with Adam at Avalon RV. He did an amazing job repairing the solar system on my 37 foot fifth wheel. I have been totally on my solar system for two months now, no shore power! System is working flawlessly.
Thank you, Adam for repairing my solar system !

Adam at Avalon RV helped us with upgrading the water system on our travel lite Falcon trailer with an on demand heater, new filtration system and other mods and upgrades which all worked flawlessly! The whole team at Avalon are reliable informative and just do the best quality work.
I would recommend this shop to anyone who has an RV or trailer!

Leaving positive feedback for Adam! Saw the man about a potential axel swap on our rig. He was extremely knowledgeable, and his prices were equally awesome / reasonable. Highly recommend a ride out to see him in Benicia if your RV is in need of upgrading. Cheers and a big TY.

I recently purchased a 2022 Conqueror UEV 490. It is an Australian hybrid off-road camper. I had the hardest time finding anyone who can work on it. Adam was very honest with his concerns with this unique camper. Although it was not a camper he had experience working on, he was able to install a Max Air fan, and upgrade several elecrical components. I took the trailer out this past weekend for my first trip and it worked perfectly! I appreciate all the work Adam put into it. I will definitely bring my trailer back to Adam for future work.

Adam and team are top notch. They are my go to for all things battery and solar for our trailer. We had smaller solar and lead acid batteries before. The upgrades Avalon did allow us to be completely off grid for an unlimited amount of time. Plus we can charge our e-bikes and ride as often as we want.

Frequently Asked Questions

1. What is solar energy?

Solar energy is the energy harnessed from the sun’s rays using solar panels or other solar technologies. This renewable energy source can be used to generate electricity or heat, offering an environmentally-friendly alternative to fossil fuels.

2. How do solar panels work?

Solar panels convert sunlight into electricity through photovoltaic cells. These cells capture sunlight and generate an electric current, which is then converted into usable energy for homes or businesses.

3. Is solar energy expensive to install?

The initial cost of installing solar panels can be significant, but it varies depending on factors like location, system size, and installation complexity. However, incentives, tax credits, and long-term savings on electricity bills can make solar energy a cost-effective option over time.

4. Can solar panels work on cloudy or rainy days?

Yes, solar panels can still generate electricity on cloudy or rainy days, although at a lower efficiency compared to full sunlight. Solar energy systems are designed to harness available sunlight, even in less-than-ideal weather conditions.

5. How long do solar panels last?

Most solar panels have a lifespan of 25 to 30 years. After this period, they still produce energy, but their efficiency may gradually decline. Regular maintenance and monitoring can help ensure the longevity and optimal performance of the system.
