The Cost and Benefits of Solar in Portsmouth
Although solar panels can save you a decent chunk of change on utility bills over time, it's necessary to consider the startup costs. Some key factors that determine the cost of installing a solar panel system on your home and how much money you could save over time include:
- The model of solar panel system you can afford: This hinges on what your budget is.
- How much you spend on energy: The average household in Portsmouth shells out around $880 a year on home energy use alone, so you could be looking at that much in savings.
- Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your utility bills, which can generate an average of $21,000 of savings over 20 years.
- Electricity consumption: The average home in Portsmouth doesn't use much energy, and as a result may not see as many savings on their power bills.
Thanks to the cost of solar panels being lower than before as well as several solar incentives, they are a solid investment for most homeowners.

Environmental Impact of Switching to Solar in Portsmouth
One of the most compelling reasons to use solar energy is to reduce your reliance on traditional energy sources like burning fossil fuels, which are harmful for the environment. A question many people might have in mind is how much can they really help preserve the environment by switching to solar power anyway? One thing to consider is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. After you go solar, your carbon dioxide emissions can be cut by about 40 pounds each year. If you want to do what you can for the environment, you'll no doubt recognize that there are many good things about adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.

EcoWatch's Portsmouth, RI Solar Company Rankings FAQs
What is the best solar installation company in Portsmouth?
The highest-rated local solar company in Portsmouth is Alternative Energy Store, Inc., with a rating of 5.00 stars.
What is the negative environmental impact of solar panels?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Solar panel manufacturing 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 fruitful investment for most homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already fairly low, solar panels might not be for you.
When is the best time of year to install solar panels?
You can install solar panels whenever it's convenient for you, but consider doing so in the winter when there's less demand. With fewer homeowners going solar, you could potentially see quicker installation times and more savings.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
