The Cost and Benefits of Solar in Guilford
Although solar panels can save you a decent chunk of change on energy bills over time, it's necessary to know the upfront costs. Some key things that impact how much it will cost and how much you could save include:
- Where your home is: This influences how much sunlight your roof receives, which helps determine how many panels you need.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state may also have various incentives that you can benefit from. Additionally, you can save about $25,000 over 20 years on your utility bills, not including incentives.
- Electricity consumption: The average household in Guilford doesn't use much energy, and as a result may not see as many savings on their power bills.
- Your income and budget: This shapes what type of solar panels you can afford.
There are many good benefits of solar even with the upfront cost of installation. It can help the Earth and your wallet. Additionally, it can boost the value of your home, resulting in even more benefits if you choose to sell your home later.

Our article on solar incentives has more detailed information on the incentives you can take advantage of in Guilford.
Environmental Impact of Switching to Solar in Guilford
Many want to do what they can to help save the planet, which often is the prime reason for installing solar panels. But — how much exactly can you help by using solar power? According to the EPA, electricity production is the second largest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Using solar power can help put a dent in that statistic in a city like Guilford that generates a fair amount of carbon dioxide emissions each year. While solar panel manufacturing emits carbon dioxide, the panels make up for it by considerably decreasing the amount of CO2 you would have released if you still used traditional energy. In Guilford, you can reduce your carbon footprint by 40 pounds a year with solar panels. For people who are worried about the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.

EcoWatch's Guilford, CT Solar Company Rankings FAQs
Which solar installation company is the best near me?
In Guilford, Phoenix Energy is the best local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to add solar panels to your roof.
What are some of the biggest pros and cons of adopting solar power?
The advantages of solar power are that it can lower or, in some cases, 100% erase your electricity bills, raise the value of your home and lower your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save as much if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
Is it worth putting solar panels on my house?
Solar panels can be a great investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already reasonably low, solar panels might not be for you.
How often do solar panels need to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency after that time.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
