The Cost and Benefits of Solar in Harwinton

The cost of installing solar panels has dropped significantly over the past several years, but it's still a large investment for most homeowners. Some key things that affect how much it will cost and how much you could save include:

  • Your home's power bills: Based on the fairly high monthly energy bills in Harwinton, you could save about $1,100 a year with solar.
  • Choice of solar panels: The kind of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 26% of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $22,000 over 20 years on your energy bills.
  • How much energy your home consumes: Homes that consume lots of electricity each month may call for more solar panels and, as a result, more upfront cost, but will also save more on their energy bills over time.

So is installing solar panels worth it? Whether you'd like to decrease your electric bills, carbon emissions or both, solar panels are a good investment for many Harwinton homeowners.
