Solar pool heating system prices for a residential pool can range anywhere from $2500 to $7000. The location and size of the pool, location of the solar panels, desired temperature and season, and type of pool equipment determine system size and costs.
1 Automatic pool cover: $11,000.  Solar panels: $10,000, although most system are far less than this. We used SunEarth panels so that the pool can be warm for my daughter's birthday party in February. It still needs gas heat to get all the way to 80 F, but the panels do most of the work.
