My plumber, who installed our system and has the same himself, suggested we turn off the hot water tank and just let the solar system do its thing when it's sunny. I've tried it over on a few occasions for, sometimes, weeks at a time and we still had a good supply of hot water every day just from the solar collector. This may be common knowledge already, and I may just be late to the party, but it makes a noticeable difference to our bill. Try it for a few days and see what happens. #grownostr #solar #hacks
