🚍 ECO-WORTHY 25W 12V Poly Solar Panel Module for Off-Grid RV and Boat Charging Review

Bought this product for remote camping to run the dog fan. The product looks good, but do not use electronic devices such as inverters when the solar panel is connected. I smoked 2 inverters while this one was on battery. The main reason. The cell produces 13v even in low light, around 21v in full sun. My settings were good in the morning until the sun was directly overhead when the smoke started. Recommended voltage regulator when purchasing this product. I would have given it 4 1/2 stars if…

My barn has several of these panels - and just added another one, hence this review. 3 years of continuous use without maintenance so far without problems. 3 full years without cleaning cost it somewhere around 33% efficiency loss, which surprisingly was completely eliminated by cleaning/polishing. had to wash it and then use a headlight polishing kit to remove the oxidation and restore it to near new condition.

I have another 25w panel that I ordered from Revain that I have tested at 25w in full summer sun. When this one arrived, I immediately noticed that it was smaller than my other panel, despite having identical starting specs, which made me suspicious. I don't have the right equipment to accurately measure the power, but this panel definitely puts out less power than my actual 25w panel with the same amount of light. Estimating based just on some quick multimeter readings I'd say this is closer…

Enjoying this panel. We are fully photovoltaic powered and have several smaller panels for charging remote control batteries and bats for boats and vehicles. If you plan on leaving it unattended I highly recommend one of the inexpensive Chinese charge controllers to prevent overcharging and discharging overnight. Make sure your charger is rated for 20W. For small applications it is easy to connect an inexpensive lamp cable. Pay attention to the polarity! I use a "thick" ground pin and cut the…
