Utility rate schedules for commercial and agricultural accounts include demand charges, which are not eligible to be offset by solar credits. Typically, demand charges and other customer fees equate to 20-30% of your annual bill. In most cases, this allows a solar system to eliminate up to 80% of your energy bill.
If there’s a blackout will my system still produce energy?
Because net energy metered solar systems are grid-connected, your system will not produce energy during a power outage. The inverters are specifically designed to turn off when a minimum voltage is not met; this protects the system components from unexpected changes in power coming from the grid, such a power outage or even a power surge.
Should I install extra solar and sell it back to the utility?
Utilities are not required to compensate you at retail energy prices for energy produced in excess of your cumulative usage over a 12 month period. Some utilities will pay a wholesale rate for over-generation, while others may not compensate you at all for net excess energy that occurs over a 12 month period. This is why it’s important to review your annual energy needs and appropriately size your solar system.
How can I Compare multiple solar bids to confirm accuracy?
PVWatts is a free online solar tool provided by the National Renewable Energy Laboratory (NREL). It allows you to input your site location and system specifications - provided in your solar quote – to verify the expected energy output. It’s free, reliable, and easy to use!
How long will my system last?
While most solar module manufacturers provide a 25-year power output warranty, your solar panels will continue to produce energy for years to come. Solar systems degrade at 0.5% annually, so overtime they generate a little less energy every year. There are systems over 40 years old in-service that are still generating energy!
