> pretty sure solar only barely pays for itself. depends on location and energy prices. in areas where electricity is expensive, and sunlight are plentiful, it pays back shortly. > the idea is that in a home installation, would recommend against insalling it on roof of living home. at least, in more northen climates. as there can be some issues during montage, and later during some storm or snow, there some movement happening, which introduces leak in a roof. can be expensive and comlicated to fix that issue. if on some shed, warehouse or unheated garage. in places, where it is easy to inspect is there some issues, there yes. it can be good way how to use extra space. > which is great, but they don't tell you that solar panels burn out in 10 years nah, it is like 15 years, and it degrades by like 15% not big of a deal. there is no point to run at 100% of manufacturer capacity, at all stages of lifetime. most are not worried when their mobile phone runs at 70% of battery capacity. usually it gets replaced, because it is either broken, or lost, or needed applications do not support it anymore.
