1500W 12V Monocrystalline Solar Panel(6X250W)

SKU: NPA250S-15I/06

Product Rating:


Newpowa's 250W Monocrystalline High-efficiency Solar Panel is ideal for bringing power to applications when away from the grid. Perfect for larger off-grid solar systems, sheds, cabins, boats, and RVs! Available in bundles of 6 panels on our website.

New design

All-black frame made with corrosion-resistant aluminum will reduce the risk of rust accumulating on the panel.

9 BusBar Features

  • Under ideal conditions, 9 busbar PV module will outperform the dated 5 and 6 busbar technology. The void space reduction between the 9BB solar cells is designed to enhance the overall efficiency of the PV module by lowering current lengths and mitigating against loss of output.

Key Features

  • Higher cells efficiency, better light converting rate
  • Maximum Efficiency: 21.3%

    The solar panel's frame is solid and had holes already drilled into the frame. I placed washers on the top and bottom of a bolt that ran to an L-bar cut about 12 inches in each of the screw hole sections. Into those I ran u bolts around the bars in my roof rack. And just for extra safety I added zip ties in case one of the bolts worked out.

    We mounted four of these on our sailboat a few weeks ago. Because they are mounted flat, and there are numerous shade-producing elements and the array produces usable power at very low sun angles (early and late in the day). I'm very impressed with their performance, along with our Victron MPPT controller.

    I've installed two of these and they work well.

    The panels seem to be great quality and during my brief testing seem to perform as advertised. I would have no reservations with recommending these to anyone looking for high quality panels.

    Needed a second soler panel on the RV I live in for extra fan power. This does more than I was hoping for! Easy to hook up to an addition soler panel.

    I bought this panel to keep my auxiliary batteries charged up for my RV. Great buy! In fact, I am going to buy another one soon. Super easy to install and connect. I suggest buying the correct gauge connection cables for the panel to the solar controller, and the solar controller to the battery. The panel has kept my two extra batteries full and it hasn’t even had a day of full sunlight. Definitely recommend by me. Thank you!

    Panel in well built and has withstood higher winds with no problems. Overall output is net the %70 percent range at peak times that is expected from this class of solar panel(same or above several other common name brands). Bought as a test. Starts producing power with little light early in day and late evenings.
