Newpowa 9BB 30W 12V Solar Panel High-Efficiency Monocrystalline 12V PV Module Designed for 12V Off Grid System, Charge Your 12V Battery of RV, Boat, Camper, Trailer, Gate Opener(30W New)

Panel arrived in good shape with no scratches, frame damage or hairline chip cracks. Output in full late afternoon sun was as specified. Small enough for the smaller needs while still providing decent output. Panel supplied with bare wire ends, which was fine as I was installing PowerPoles, anyway. Wire lead length was about 2-3 feet long. This worked well for my use, as I didn’t need longer leads, and it’s less voltage drop with the shorter wires. I plan to use the panel to charge various 20Ah and 35Ah batteries for use with an inverter during short power outages. Also have a 110Ah AGM deep cycle battery and 100W panel that when used with a 2000W inverter will run the fridge plus some extras for about 10 hours. The smaller batteries work for backup while the larger battery is charging. Plus the 30W panel can be paralleled with the 100W panel for better output in less than full sun. In the last 20 years we’ve never had power outages longer than 5-6 hours, so the planned system will handle expected needs. Less expensive than a generator (about half the cost or less of a Honda 2000 and no maintenance). I realize that there may be cloudy days during a power outage, but fuel supplies also run low, generators break/need maintenance, and stored fuel needs to be cycled through to prevent spoilage. Still may get a generator in the future. Also use the solar panels/batteries as backup and portable power for my ham radios. The smaller batteries and panel work best for this, as the 110Ah AGM deep cycle battery is a bit heavy. This panel works great for what I bought it for. Before buying a solar panel would recommend researching what’s required for your planned use (power needs, battery size, length of your wire run, panel sizes, whether a 24V/48V system with a step down controller may be better than 12V if using longer wire runs, portable or permanent use, etc.) so you don’t spend unneeded extra cash or end up with a cheap panel that doesn’t work well for what you need.

very happy I have this mounted on my dump trailer and it is able to keep the battery charged up between hauls ( we use it a few times a week ) this is the only charging it gets or needs ! thanks for the great product.

Good product

Comes ready to use, works as advertised.

I'm using this to power a 12v circulation pump between my electric water heater and my solar water heater on the roof. This panel is extremely well made and produces plenty of electricity... 24v in direct sun!
