Q: How quickly will my system pay for itself?
A: Depending on the site and your hot water costs, the system usually pays for itself in 3-7 years.

Q: How much of my hot water will solar hot water heat?
A: A solar hot water system will provide 70-85% of your hot water with free energy from the sun.

Q: How do I know if I have a good location for a solar hot water system?
A: A good location must have the following characteristics:

  • A building where you are permitted to install the system.
  • A location on the property (roof, wall, or ground) that is south facing and shade-free from 9 am to 4 pm in all seasons.
  • The shade-free area must be large enough to hold the number of panels you want (approximately 4 feet by 8 feet per panel).
  • An accessible location for the storage tank.

Q: How much will my solar hot water system save me each month?
A: This depends on how you currently heat your water and the current cost of energy. A solar hot water system will likely save between $25 to $80 a month for an average home.

Q: Why is the system so expensive? I can buy an electric water heater for far less than that. 
A: When you buy a solar hot water system, you're buying the tool for collecting free fuel for 20+ years. You have to pay your electric bill to pay for the fuel for that tank after you install the electric hot water tank. Your total cost to operate a solar hot water system over its expected 20+ year lifespan will be much lower than for an electric hot water system. After rebates and tax credits, the money you save on energy costs pays back the cost of the system in 3 to 7 years. Then, for the rest of the time the system provides you with hot water at almost no cost.
