If maximum per-panel-Wattage is your goal the Longi LR7-72HGD-600M fits the bill! At 600 Watt (and that is just for the front side, this is a bi-facial panel) these are about as large as they get. Longi model LR7-72HGD-600M is 72-cell (actually 144 split-cells) bi-facial solar PV module. Bi-facial means the panel can convert light into electricity from both sides, the front as well as the back. The Wattage rating is based on just the front side, whatever the backside produces is a bonus! Longi is a well-known A-brand Chinese producer of solar panels, that offers excellent value for money. These are regular silver-frame panels, with glass on both sides (since they are bi-facial modules). The ‘back’-sheet is white (it’s in the middle between the two layers of cells). Despite their size these panels are rated to be mounted using the usual two rails. This is a single panel. Full pallets of 36 panels are available as well. Please note that due to their size we cannot ship single panels. Full pallets are available for shipping. Features 30 mm frame Rated for 1500 Volt strings Mono-crystalline HDPC cells, 144 split-cell module High-yield panel, with an efficiency rate of up to 23% Guaranteed positive power tolerance sorting: -0 … 3% Low temperature coefficient of just -0.23% – resulting in higher real-world yield and high CEC rating Anti LID, and anti-PID Technology, Hot-Spot-Protect for long-term reliability High-tech aluminum alloy frame, certified for high snow (5400 Pa) loads 12-year full product warranty and 30-year linear performance guarantee UL and CSA listed for Canada & USA
