Question:-How much does a solar system cost?
Answer:-This is absolutely the most frequently asked solar FAQ on the planet. Don’t just say that it depends on many factors, yada, yada, yada, get a quote. These customers are really looking for a number, not an explanation. If you don’t have a simple website estimator tool, then give a price range with the explanation that everyone’s price will depend on a home’s current energy usage and how much of their bill they want to offset. At the end of that statement, be sure to have a “call to action” along the lines of: “To get a free accurate quote, please fill out this form, or contact us,” etc.

Question:-How does solar work?
Answer:-I’m often surprised about people who don’t know the difference between solar PV and solar thermal, so be sure to briefly explain that difference and what kind of solar service you provide. Often, people think that “solar” is one or the other, not realizing there are two main solar technologies that can apply to them. For PV, mention the sun, the panel, and the inverter, and be sure to mention that there are no moving parts, so very little maintenance.
