Product and service mix
SunRise Solar Inc. manufactures and sells solar-powered attic fans (roof vents that run entirely on a built-in solar panel). The attic fan removes hot air from the attic to keep the house cooler.

The product also extends the life of the roof shingles which are petroleum-based products.
