I ordered the CMP23115FX-120-ST panel for a special project on my Toyota Tacoma to create an on board solar generator to charge the main battery and a lithium battery. The first panel I received was defective, it generated random voltage and no current so I pretty much chalked it off to the protective diodes in the junction box. I contacted Tom and let him know everything I could tell him without disturbing the sealant in the junction box. He quickly put me in touch with Cindy to arrange a replacement. I have received the replacement and am very impressed with the improvement of quality in the new junction box which has cable restraints and better cable which is easier to work with when installing. The new one also seems to have upgraded solar cells. Guys thank you very much for looking after me in my custom truck generator! Also to everyone else, you’d be taking a chance if you don’t obtain your solar needs from these guys!

I did a search for a solar panel system for my Bavaria 35 and Tom's website was the most clear and straightforward website I found. And Tom was extremely helpful in helping analyze my electrical load needs. He put together a great system of semi-flexible panels to be located on my bimini, two 145 watt panels and two 55 watt panels. They work great. I highly recommend Tom and his company, Custom Marine Products.

did just what I wanted; kept the batteries up over the winter

Easy installation and it’s pushed us over the line in sustaining our demands to run the boat’s loads through the day in the Bahamas!

We installed two 155 watt panels, and two 120 watt shade tolerant panels one year ago. These have generated more than enough power to run refrigeration overnight at anchor. The panels are bimini mounted with the shade tolerant versions near the boom. I highly recommend the shade tolerant versions as in practise they perform as well as the higher wattage panels.

I bought and installed this unit with Tom's help and advice over email back in 2020 and it has been a huge help ever since. It makes our battery bank seem twice as big and has taken a decent amount of abuse occasionally getting walked on.

Couldn’t be happier.
