Yes, but performance may be affected. Solar panels produce more energy when the sun is shining.

Solar power is energy that comes from the sun, while many other forms of energy come from fossil fuels (coal, petroleum, and natural gas). Both can be used to power your home, but they are generated differently. Energy from fossil fuels goes through multiple steps before reaching your home, including step-up transformers, transmission substations, and distribution substations. Solar power is collected by panels on your roof, then immediately converted into usable energy.

We conduct an on-site survey to determine if your site is compatible for solar. Here are some examples of what we evaluate to make sure that solar is a good fit:

• Roof size, pitch, and direction
• Shading of the roof caused by tree branches, other buildings, etc.
• Roof obstructions such as chimneys, pipes, etc.
• Roof stability and strength
• Electrical wiring

Yes, slightly. Due to sun exposure, weather and other environmental factors, there's a potential degradation rate of 2.5% the first year the panels are on your roof, and 0.7% per year during the rest of the 20 year term. Most of our panels degrade at a rate lower than this, but we guarantee that they won't degrade more than the above amount.* *Warranty refers to solar panels. Refer to your customer agreement for all warranty terms and conditions.

There are many factors that affect the production of a solar panel (location, orientation, tilt, weather, season, shade, etc.). Solar panels produce varying amounts of energy through the day. In the mornings and evenings, when the sun is low in the sky, solar panels will generate less power than in the afternoon when they are receiving direct sun exposure.

No. Our solar panels are not attached directly to your roof, but rather to a racking system that has been wind, water, and fire tested to ensure no leaks or damage will occur. Additionally, shingles on your roof will often last longer under installed panels because they are less exposed to UV light.

Depending on the net metering laws and utility provider in your state, excess energy generated may roll over as a credit toward the next month's bill (credited on an annual basis), or paid to customers as a refund.
