Why Go Solar? Frequently Asked Questions about Solar Energy

Solar Hot Water

Q: How do solar thermal systems work?
A: Fluid running through a solar collector is heated by sunlight hitting the collector. This heated fluid circulates through a storage tank, where it transfers its heat to the water in the tank. The storage tank is part of the regular water supply and is installed upstream of the conventional water heater. The solar fluid never touches the water. Schüco’s unique third-generation system design handles this process very efficiently, for quieter operation, better output, peace of mind, and much less maintenance than conventional thermal systems.

Q: Will a solar thermal system give me hot water if there’s a power outage?
A: The pump that circulates the solar fluid runs off electricity, so in a power outage it won’t operate, unless you have a standalone system with battery backup.

Q: I’ve seen houses with old solar collectors that are full of unsightly algae. Can that be avoided?
A: Yes. The technology has made huge strides since then. For example, our solar collectors use propylene glycol instead of water. Propylene glycol is a more efficient heat transfer agent, it doesn’t freeze, and algae won’t grow in it. It is safe and nontoxic. And of course, the collectors look great on your roof.

Q: Can a thermal solar system leak?
A: Theoretically anything can leak, but it is extremely unlikely that a properly-installed Schüco
solar system ever will. We have one of the world’s best-equipped test facilities, and test our products more rigorously than any standard requires.
