Frequently Asked Questions

Can I heat my house with solar?

Although solar electric technology provides electricity for your home, it is not ideal for operating electrical heating loads, which require a considerable amount of power. Solar thermal technology is designed to turn the sun’s light into heat instead of electricity. A solar thermal (water heating) system may be used to supplement a radiant floor heating. However, there are things to consider about this application. read more >

Does solar work in WA state?

Yes, solar works very well in the Northwest!  A common misconception is that PV modules work best in hot, arid climates.  Actually, PV modules operate most efficiently in sunlit, cooler climates.  Washinton's climate is not only temperate, but also has excellent sunlight available throughout the day in the spring, summer, and autumn seasons.  Because PV also works in cloudy conditions, wintertime also yields performance.

Where are PV modules made?

PV modules commonly used for residential and commercial systems are manufactured in Europe, Asia, and North America. Silicon Energy (SiE) brand modules are made in Washington state. Incentives of up to $0.64/kWh are now available for systems using Washington-made equipment.
