Frequently asked questions
- Is my roof suitable for solar?
- We use satellite images to check for shading as well as orientation; contact us to assess your roof
- What size system do I need?
- We can estimate how many panels could fit on your roof, and compare this to your current usage. Contact us with your address and a recent electric bill (or usage data).
- How is a solar project sized and priced?
- Generally, if space allows, the aim is to install a system that will generate the same amount of electricity as you use in a year. Though you’re billed for electricity use in kilowatt hours (kWh), solar projects are sized in kilowatts (kW), and priced by the watt ($/W). Generally, the larger the system, the lower the price per watt due to economies of scale. We’ll help translate for your project.
- What am I getting when we commit on a solar project?
- You typically get solar panels, racking and an inverter – installed. You also get a warranty from the installer, typically for 10 years on the equipment and labor.
- How long do solar panels last?
- Solar panels are considered a 25 year investment. Though they continue to operate well past that, they generate less and less energy over time.
- How do I maintain solar panels?
- You don’t. In our region, dust & pollen gets washed off by rain and snow.
- What’s the warranty for these systems?
- The manufacturer of each component typically warranties them for 20 years. The installer warranties their work for about 10 years. There’s also a warranty for the power produced by the system, about 80% of the system’s original capacity for at least 25 years.
- What if the power goes out?
- Most installations are grid-tied, meaning you lose power when the grid power goes out, even if the sun is shining. This is to protect nearby workers repairing the downed power lines. If you want electricity when the grid is down, you’ll want to ask for a battery backup system as part of your quote.
- What if I generate more than I use?
- Since most systems are grid-tied, any excess power is fed back to the grid. The utility compensates you via a concept called net metering, because our combined added power helps them during periods of peak demand.
