I purchased two 200W mono panels for my boat. SBP's ordering system and status updates are good. I am replacing two 100W mono panels. These new panels perform very well. They perform to the published specs which is not the case with all panels (including the ones I am replacing). In comparison with my old panels, they are noticeably more shade tolerant, the temperature coefficients are better and I am getting more energy delivered in cloudy conditions. Many panels for 12V or 24V applications are rather "average" to say the least, but I find these excellent with their performance on par with Grade A panels for rooftop or solar farm applications. With regard to the company, they are excellent to deal with. There was a glitch with part of my order and the company fixed this very promptly so SBP is on my "good companies" list.
