How to Calculate Solar Collector Heat Output for Your Pool System
Calculating solar collector heat output is straightforward: multiply your collector area (in square feet) by the peak solar insolation in your region (typically 250-350 BTU per square foot per hour) to determine hourly heat gain, then compare this against your pool’s heating load to verify adequate coverage. Most residential pool owners need between 50% and 100% of their pool surface area in solar collectors to maintain comfortable swimming temperatures, depending on climate, desired temperature, and pool usage patterns.
Understanding these numbers before you buy ensures your …
