I live in the North East in a suburb near Boston. The picture shown below was the original 6, 100 watt bifacial panelspanels I started with. During the winter, I purchased 2 more panels for a total of 8, expanding my home made racking system. I have them in a series connection with 2 groups of 4. I have a combiner box on the rack that will take up to 4 strings of panels.During the last week February, after some of the last snow fall we received, I recorded 1033 wats of solar production mid day. This is more than 200 watts over the combined rating of those 8 panels. I use a HQST 150v charge controller, charging 3 DC House 51.2v 50ah LifePo4 rack style batteries. I have them connected to a Bluetti AC180 through it's solar charging port which will accept 500 watts of continuous charging. I purchased 4 more of these panels and added them to my array for a total of 1200 watts. I've had mostly cloudy days since installing them and still reached almost 1400 watts on the best of those cloudy days so far. I will without question buy more of these panels as they are fantastic and the configuration options are awesome because of their size, voltage and efficiency. If your not getting simular results, remember to find the best position balance to capture as much sun as posible and get them off the ground. They don't need to be positioned at a steep angle either, since they capture light from behind as well.
