Project description
Background Commercial differential solar controllers are typically designed for relatively simple applications. Their primary responsibility is to compare collector and storage temperatures and activate a circulation pump when enough thermal energy is available. While this approach works for basic solar hot water systems, real installations often involve significantly more complex operating conditions. The project presented here was developed for a large residential solar thermal installation with approximately 600 gallons of thermal storage. Instead of managing a single circulation loop…
