Offset Your Costs with Solar Rebates and Incentives. Solar energy is environmentally friendly, free and nearly endless. That’s why federal, local and state governments have tax credits and solar rebates for people to install residential solar systems. The incentives can substantially reduce the cost of purchasing and installing a solar energy system in Ontario. For more information, read about the solar rebates and incentives below or call Stan's Heating, Inc at 541-286-6602.
