Quick answer

Institutions use a lot of hot water at predictable times (morning showers, kitchens, laundry), which makes solar water heating very cost-effective. Large systems combine several collectors or an array feeding big storage tanks, with a backup heater and controls, sized from actual daily demand rather than guesswork.
