The Cost and Benefits of Solar in South Portland
Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you must first pay to set up your panels. Some main factors that influence how much it will cost to install solar panels on your home and how much money you could save over time include:
- System size and type: Some models are more expensive than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 26% of the project cost. Your state and city may also have various incentives that you can benefit from. Plus, you can save about $16,000 over 20 years on your utility bills, before factoring in incentives.
- The amount of sunlight your roof gets: If your rooftop doesn't get a lot of direct sunlight, your solar panels won't be able to generate as much energy, which will give you lower savings on energy bills than a roof that gets plenty of sunlight.
- How much energy you use: If your home regularly uses a lot of energy, you'll see more savings from going solar.
Because of solar panels decreasing in cost as well as various solar incentives, they are a worthwhile investment for many homeowners.

Environmental Impact of Switching to Solar in South Portland
One reason so many people consider switching to solar power is to help lower their environmental impact. You may be wondering — how much do solar panels help the environment anyway? In a city like South Portland where energy use is rather high, making the switch to solar power is a fantastic idea for homeowners who care about the planet. Because solar panels don't release greenhouse gas emissions into the atmosphere when creating electricity, they're a good swap for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 40 pounds each year. If you care about the environment, you'll most likely find that there are many advantages to adopting solar power other than just saving money on electricity. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's South Portland, ME Solar Company Rankings FAQs
What is the most reputable solar panel installation company in South Portland?
In South Portland, Sunlight Solar Energy, Inc. is the best local solar company. Our team of experts rates it 4.68 stars, so it's a great choice if you're planning on installing solar panels on your home.
Are solar panels really eco-friendly?
Solar panels can be harmful 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 uses a lot of energy as well. The energy payback period is about 1 to 4 years.
Is it worth putting solar panels on my roof?
Solar panels can be a fruitful investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already pretty low, solar panels might not be for you.
When should I put up solar panels?
Despite summer being the most common time people install solar panels, the optimal time is actually winter. You can save money since there's not as much demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
