If I could give 0 stars, I would. Dave installed a 400 watt solar kit with 2 lithium ion batteries and within the hour the batteries were depleted, without powering ANYTHING. He promised to stop by the next day but did not. And continues to refuse to help. My solar panel do not work even when the sun is out. This is another review from another one of his clients left on google. We had Dave put a pretty big set up on our RV. Our set up should last a few cloudy days once we get a full charge. The day of it seemed like power was flowing to the batteries. Next day the batteries were completely drained. We would get them up to 100% charge, within a couple hours of the sun going down, our batteries are empty and we have to run our generator. We tried to get Dave back out to look at it, he set up a day and never showed. We called him repeatedly and would get voicemail, maybe he would return the message a few days later, maybe not. Eventually we just stopped hearing from him. It has been months and we have no real benefit from having solar. I recently tried to text him again, still no response. Dave please contact us and fix what you installed. If we finally get a resolution maybe I will update my review. read more

Sad to say, but Dave isn't that familiar with RV solar installs. We had ours installed back in April I believe and although it works, there aren't any disconnects or fuses to protect the electronics. If you go look at a install for an RV you'll see there is a big difference than what we got. Go to YouTube and see how it should be done before he does yours. I've tried contacting him, but no response. Do your homework and make sure it's done correctly. I will probably have to spend a lot more to correct his failures. read more

I've held off for a couple of weeks to write a review, because I wanted some time to pass before I formed an opinion. Bottom line: I'm happier today than I was the day Dave finished the work, and I was pretty stoked that day too. I was a little hesitant at first, because the work is 100% prepaid online to a complete stranger. That's not normal, but Dave has been a man of his word from the very beginning. I paid for the 700w system (plus controller and BlueTooth module) and then we scheduled the installation. We had communicated by text beforehand, so my questions had already been answered and we had already set a tentative service date. On the day of the service, Dave arrived at the yard where I store my RV and he got to work. He and I spent about twenty minutes talking about my current system (four 6v golf cart batteries and a 2000w inverter) and then we discussed the location for the monitor panel. I'm kind of a tech dork, so I don't mind seeing the panel, but I knew my wife would want it out of the way. We finally picked a location that made sense in one of our closets and then I got out of his way. With seven panels on the roof, plus the controller, plus the wiring from the panels to the controller and then to the batteries, Dave had a big job on his hands. I stuck around in case he needed another set of hands, but he was very self-sufficient. Dave did a very clean job with the installation. The wire run turned out to be trickier than he expected, but he ran the lines underneath some drawers in the bedroom and then bundled with some other utilities. It turned out very very clean. I didn't climb up on the roof to look at the panels (I hate the roof), but when I brought the trailer home I could see the panels from my 2nd floor bedroom window and he did a great job mounting them. Fast forward to however many weeks it's been since the install and I had to stop by the trailer at the storage lot to grab something. It's been cloudy and rainy for days, so I didn't expect much of a charge, but the batteries were at 13.6V, which is pretty doggone good. I hadn't flipped the battery disconnect switch like I usually do, since the solar should keep things charged. And I had accidentally left a light switched on, which would have killed the batteries in a couple of days, but the solar panels more than compensated for that light that's been burning 24/7 for weeks. We've gone on one dry-camping trip since adding the solar and it a completely different experience. We barely ran our generator and had all the power we needed. I would absolutely use Dave and High Watt Solar again. read more

Dave was fantastic. We bought 6 panels and a converter to turn our 28ft. Leprechaun into a free energy living system that we can travel in and use easily. He was honest, fair, did clean and accurate work, worked hard and diligent until completed, he tried everything out with us and taught us how to run in and he is very friendly and informative. We had a wonderful experience and we are very satisfied. Thank you Dave read more

I recommend high watt solar. Dave is professional, knowledgeable, hard working, on time, and takes responsibility when necessary. I had a six panel solar system installed in my Motorhome including a powered inverter. Even though I had some issues with the first two automatic switches that connect to the appropriate power sources, Dave invested his time to research the issue and find me a switch that works. Thank's Dave! read more

Today it's very hard to trust what you read and even find someone that even knows what they are doing. High Watt Solar not only made me feel like he new what he was talking about but he came out the day he said and installed an amazing system. My 2020 Grand Design Momentum ended up pulling a lot of watts and he new exactly what to do to handle it. With my 5 panels, 4 lithium batteries and a 5000 watt inverter, I can go to the desert and almost run everything without running my generator day and at night. He accomplished everything I was hoping for. I highly recommend High Watt Solar to anyone that's wanting a complete Solar System on their RV read more

Great guy who is like a detective for electrical problems. We had an issue with our solar panel for weeks and couldn't get anyone to get us an answer without charging and arm and a leg, but High Watt not only came in to diagnose the problem in minutes, but fixed it in no time as well. Glad to actually have someone that we trust which we can reach out to about any future problems that might come up. read more

Im super happy with my the solar system Dave installed for me... I've had it for a year and it's never gave me any problems. I watch a movie or two with the day's charge and I still have more than enough power to leave a light or two on for hours, and I don't even have to waste anymore gasoline trying to charge my batteries. Thank you Dave read more

I never did a review but I had to do this one because I'm very disappointed. I hired Mr. Demack to perform a few jobs in my RV. He was paid in advance and started them but never finished them. I also keep having trouble with a camera installation. I have called, texted, emailed him but he simply disappeared. I will reconsider this review if he finishes what he started. read more

Terrible customer service once system is installed. Never return calls or texts it's almost like he knows he does a terrible job with the installation and doesn't want to deal with his mistakes. Buyer be ware. read more

I called Dave at High Watt Solar RV, he spoke to me over the phone trying to rectify the problem before coming out on a service call. He is a fair and honest man. Truthfully I am embarrassed to say I was a little concerned when I saw what he was driving, all I can say is I will never judge a book by its cover! He said he would figure out the problem within the hour, he is true to his word, he had to rewire an existing problem but did not charge a penny more. I CANT SAY ENOUGH ABOUT HOW WONDERFUL HE WAS. THANK YOU DAVE! I highly recommend him to get the job done right! read more
