2.7 GW of bifacial panels to get deployed in China this year. Good. We’re going to get a lot of real world efficiency gains and research that comes from glass backed bifacial solar panels. Even if we only get 10% of the electricity that the front gets, we’ve just got a 10% efficiency boost at a seemingly minimal cost. As it scales, many panels will angle for this – but we still may a white backsheet reflects more than some situations (black asphalt shingle tile?).
China is expected to jump-start the market for panels that can absorb light on both sides with plans to install 2.7 gigawatts this year, according to research from Bloomberg New Energy Finance.
