Frequantly Asked Questions

Do solar panels need to be mounted on my roof?
Panels are mounted to the roof, but can be mounted on the ground. Ground mounts are great if the house is shaded or if dormers or obstructions limit available space on the roof.
What happens when the utility has a power outage?
The systems we sell are "clean power" systems without batteries. These systems do not generate power when the utility is out, even if it is sunny. If backup power is desired, a battery system can be added. This increases the complexity and cost. Most people find that what they want is Clean Power, and find that the very occasional outage does not bother them, so they do not purchase the battery option.
How long will the system last?
The solar panels have a 25 year power warranty from the manufacturer. This is longer than almost anything else you can buy. The rest of the system has a 5 year warranty in most areas. Inverters can have warranties up to 10 years.
What is the weight of a solar panel?
On average the weight is 23 pounds.
Will the weight of the solar panels affect the roof?
No, the average combined weight of the modules and rails is 3 pounds per square foot.
If I sell my home, will solar affect the sale price?
Solar adds value to a home. Surveys have shown that for every $1,000 saved per year, $20,000 is added to the home's value. Solar is one of the best home improvement and investments you make.
What happens if the panels are shaded?
PV panels should be installed in areas where they get significant shade-free sun every day. Even small amounts of shade can very significantly reduce the output. Our designs and installations also seek to minimize the impact of any shade issues through selection of the proper equipment and good engineering.
Does solar work for flat or commercial buildings?
Yes, anywhere electricity is used you can use solar electricity.
Are the panels sturdy?
Yes, while the panels are made of tempered glass, they are quite strong. The panels pass hail tests.
Do solar energy systems have warranties?
