Next day, my storage was full by 8am. Granted this is summer, though this is the ideal time to rate these and judge them for what they can do. Some other reviewers state they don’t deliver but I can assure you that my panels deliver equally, efficiently and are working well with the environment they are in. I hope this update helps inform you to the longevity of these panels.
I purchased these panels 2 at a time last summer and I now own 8 total. It’s been more than six months post deployment and I have to say that I am extremely overjoyed by the results of these panels.
One did arrive completely shattered but the customer support is amazing and I had another panel on my door in a few days. These are durable to a point but they are made of glass so if you get a broken one, don’t sweat it!
I configured my panels to work as series/parallel to a solar combiner box. From my solar combiner, I send the combined power to a controller that then sends the power over to a bank of LiON batteries @1200ah 24vdc. In turn, a mega beefy 240v@60hz inverter draws from the batteries at 24vdc and sends two phase AC over to the ATS (Auto Transfer Switch) that controls the balance between line and inverter.
This winter, the biggest draw was my electric shop heater which runs on a timer. Most of the winter months, I managed to see a daily use of pure solar to power my entire shop. Only a few days in January did I see the switch trip over to line power.
Thanks to these panels, I can run my shop exclusively on solar! My compressor, lights, tools and even my welder all are powered by solar!
The whole situation would be unachievable if it were not for the affordable cost of these panels.I plan to add a few more and push my luck with charging an EV using solar. I just need more storage and I’m golden!
This is a fantastic purchase and the price is cutting the competition in half!
