Two issues I have with it is it takes 10-15 years to breakeven (depending on costs, location/how much sun you get etc..) the average roof lasts 15 years or so, so just around breakeven point you have to take the panels off to repair the roof, then put them back down, they also require maintenance of periodic inspections, and cleaning to optimize performance.I haven't looked into this aspect but the batteries that some systems have are expensive, I am not sure the lifespan or upkeep on these but think they need looked into and taken into consideration.Personally for me I think investing is the better return for my money right now.I hope solar prices keep coming down because we have a Tesla/Panasonic factory here that produces batteries and looking to ramp up production of a solar shingle like roof panels as well as the rear roof of my house is south facing and gets good sun all day.

The other is the useful life of a solar panel. Although replacement costs will decline as manufacturing becomes more efficient, is it reasonable to assume these will last 15, 20, or even 30+ years?
