The Cost and Benefits of Solar in Mendon

When choosing a solar company, most homeowners or business owners worry about the costs above all. Some key things that impact the upfront cost and potential savings over time include:

  • Incentives: Tax-paying citizens who purchase and install a solar energy system this year can save 26% of their overall solar costs by taking advantage of the federal solar investment tax credit. You can also save about $22,000 on your energy bills over 20 years without incentives.
  • Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
  • The amount of sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar panel system won't be able to make as much energy, which will leave you with lower savings on electric bills than someone with a roof that gets lots of sunlight.
  • How much electricity your household consumes: Households that need plenty of energy each month may require more solar panels and, therefore, more upfront cost, but will also save more on their energy bills over time.

So is installing solar panels worth it? Whether you want to reduce your electric bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Mendon homeowners.
