I recently installed an Outback Skybox with a small battery pack. Originally I was planning on waiting until Spring to evaluate whether to add more battery capacity or add some solar. I already have a grid tied system. I recently discovered an opportunity to acquire some 10 year old Sunpower 305 Watt panels for $90. The West facing patio cover where I propose to install them has some shading in the late afternoon.
I have evaluated the financial benefits and the risks associated with buying used panels. I also don't intend or need to take the investment credit on this purchase. I am looking for input about the use of optimizers to possibly compensate for some of the potential shading that this location may have. I have read that Solaredge optimozers may work but I wont have any of the powerline data available. I have heard of other optimizers that may be less expensive. Any ideas about optimizers for this situation? FWIW, these panels put out 54v and I plan on employing 8 or 10 of them in series which is within the voltage range of the Skybox.
