Could use some advice. We live in East County San Diego where the summer peaks around 100-102 and the evenings will be in the 80s. We purchased a 300 sq foot solar system for a 450sq ft pool. I know it doesn't hit the 75% minimum requirement, but how much will this really affect the system? Should we just buy more solar to get it up to ~450 sq ft of coverage? Is it worth the extra money?
