The majority of the system components we use are guaranteed for 25 years. Panels degrade at a marginal percent per year. At 25 years, they produce approximately 80 percent of what they did when they were new, and even then they still have a lot of life in them. Often the solar inverter manufacturer will have a stated warranty period of 10 to 12 years with the ability to request a warranty extension to 25 years for an additional cost.

The 25 year warranty covers manufacturing defects in the equipment. Labor is covered for five years with us. After those five years, service requests will be billed for the labor associated with any fix necessary to get your system up and running again.

No, not unless you have a battery backup system or secure power supply. If your solar electric system is tied to the grid, it will be unable to produce power until the grid power is active and stable again. Power company workers keep the grid off when they are working to fix downed power lines, and therefore your electricity will be out until the grid is safely turned on again.

A building suitable for solar will have a composite shingle roof that is no more than five years old (or you are planning to get a new roof), have roof pitches that are south- and/or west-facing, not obstructed by trees or buildings, have enough space to create a system that meets your energy needs, and have an electrical panel on the house.

When your solar system generates energy, that energy is used by your house first. So, it never passes through the meter to be counted. When your solar system produces more electricity than your home is using, then it does pass through the meter and is counted as a credit by your utility. Net energy is the difference between the energy produced by your renewable generating system and the amount of electricity supplied by the utility. Therefore, your net meter will only show the amount of energy that was excess and passed back to the grid. Your data monitoring app, however, will show many more kilowatts because it is calculating the total energy being produced by your solar electric system, including the watts your house uses immediately.
