Cost competitive

  • With strong state and federal incentives, solar hot water systems are not that much more expensive than typical hot water heating systems to install.
  • Energy from the sun is free! Operating costs are lower than heating hot water with natural gas, oil, propane, or electric resistance.
  • Since solar hot water systems use energy from the sun to heat your hot water, you do not need to worry about market changes to natural gas, oil, propane, or electric prices.

Flexibility & function

  • Solar hot water systems can integrate with any type of backup fuel.
  • Robust tanks and hardware are built to last 20 years or more.
  • Requires less space than a solar photovoltaic (PV) system, so it can be an option for homeowners who want to go solar but do not have enough space for solar PV.

Lower greenhouse gas emissions

  • Renewable energy minimizes the greenhouse gas impact of your home’s hot water.
