Frequently Asked Questions (FAQs)

1. Can I heat my home with solar energy?

Heating your home with an active solar energy system can significantly reduce your fuel bills in the winter. A solar heating system will also reduce the amount of air pollution and greenhouse gases that result from your use of fossil fuels for heating or generating the electricity.

2. Can solar panels run central heating?

Solar Water Heating uses the radiation from the sun to heat water in a panel often sited on the roof which in turn can supply that heat as hot water or to a central heating system.

3. Does solar heating work in winter?

Solar water heaters don't generate as much hot water in the winter. Systems installed in the Northeast will have freeze protection, and snow will melt off of your solar water heating collector well before it slides off of your roof.
