The Cost and Benefits of Solar in Guilford

We get that for lots of homeowners, the choice to invest in solar comes down to installation costs. The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Your current power bills: Solar panels can substantially reduce, or entirely eliminate, your utility bills. In Guilford, you can save an average of $101 a month.
  • Choice of solar panels: The type of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
  • Electricity consumption: The average household in Guilford doesn't use much energy, and so may not see as many savings on their power bills.
  • Incentives: Those who buy and install a solar energy system this year can save 26% of their overall solar costs by using the federal solar investment tax credit. You can also save about $25,000 on your electricity bills over 20 years excluding incentives.

EcoWatch's Guilford, CT Solar Company Rankings FAQs

What is the top solar installation company in Guilford?

The highest-rated local solar company in Guilford is Green House Solar, with a rating of 5.00 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Making solar panels requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

Solar panels can be a good investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already pretty low, solar panels might not be for you.

How much solar panel capacity do I need for my house?

Solar panel capacity is the amount of energy the panels can generate under ideal conditions (a sunny day around noon). The average household has to install between 20 and 35 panels to cover how much energy they need.
