The flat plate solar thermal collector from Viessmann has a modulating collector to prevent overheating. Solar thermal panels in cold climates are at risk of freezing in winter, so in the North, we use a glycol mix as a heat transfer fluid. This prevents panels from freezing but introduces new problems in the summer…

Choosing the right solar thermal water heater system. What is a solar thermal collector? A photovoltaic (PV) solar collector converts solar radiation into electricity , but a solar thermal collector is much simpler than that. It refers to a device that collects heat directly from solar radiation. That can be as…

A study showed that reflectors on solar panels can increase their performance by up to 30%. The continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations, for both residential and commercial use. Increasing the yield through reflection could make that an even…
