Costs and savings
Solar is a long-term investment, so the first questions we are asked are what it costs, how much it saves and how long it takes to pay back. The answers depend on the size of your system, the price you pay for electricity, how much of the power you use yourself and whether you add a battery.
For homes, savings come from buying less electricity from the grid, and many homeowners also want to know how solar affects the value of their property. For businesses, the case often rests on daytime demand lining up with daytime generation, which shortens the payback period. Panel technology plays a part as well, since higher-efficiency panels produce more from the same space.
Below we answer the common questions on costs, savings, payback and return on investment for homes and businesses.
