ReneSola Virtus II JC300M-24/Ab - 300 Watt Poly Solar Panel

Pallet Quantity (20 Solar Panels)
Partial Pallet Charge: $100 - You will be charged separately for partial pallet fees.


The new, breakthrough, Virtus®II solar module is an ingenious combination of the high quality and efficiency of Monocrystalline modules, with the lower cost of Multicrystalline modules.

ReneSola’s innovative ingot growth technology improves the uniformity of the grain size and preferred orientation, resulting in higher minor-carrier lifetime and lower dislocation density. The outcome is significantly increased cell efficiency.

The company’s innovative, controlled, DDS production process for the Virtus® A ++ wafers produces far fewer defects than conventional multicrystalline silicon wafers. This enables Virtus®II solar modules to achieve a 4% higher power output, yet maintain the same LID and CTM loss.

    I purchased a couple of these and recently installed them. The build quality on these better than expected and the power output seems to be exactly as claimed. Will buy again as soon as I can afford more

    Good panel

    The solar panels work exactly as advertised. They're heavy because of the quality frame around the solar cells. I'm going to buy 8 more of these to fill the roof space on my shed. The shipping arrived a couple of days earlier than I had expected :). Also, the company was very helpful with answering my questions and pointing me to the right cables online.
