The Cost and Benefits of Solar in Portsmouth
Although solar panels can save you a good amount of money on utility bills over time, it's important to take into consideration the upfront costs. The cost of solar and the savings it generates vary depending on a few key factors such as:
- The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won't be able to generate as much energy, which will give you lower savings on energy bills than someone with a roof that gets a lot of sunlight.
- How much energy costs for you: The average family in Portsmouth pays around $1,000 a year on energy use alone, so you could gain that much in savings.
- Your income and budget: This affects what model of solar panels you can afford.
- Incentives: Those who purchase and install a solar energy system this year can save 30% of their solar installation costs by using the federal solar investment tax credit. You can also save about $20,000 on your electricity bills over 20 years not including incentives.
There are several good benefits of solar despite the initial cost of installation. It can help the environment and your finances. In addition, it can boost the value of your home, leading to even more benefits if you decide to sell your home later.

Solar Incentives in Portsmouth
There are a lot of reasons why you should switch to solar. One of them includes some government incentives that can save you money. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 30% of your project costs on your tax return, lowering the amount of taxes you owe that year. Plus, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can see the incentives you qualify for near you.
Environmental Impact of Switching to Solar in Portsmouth
Lots of people want to do their part to help the environment, which often is the primary reason for installing solar panels. But how much can using solar energy instead of traditional energy actually help the environment? The amount of energy you use is an important factor to think about. The more energy your household consumes, the bigger your impact when you switch to solar energy. In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 40 pounds each year. If you care about the environment, you'll most likely understand that there are many good things about adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is invaluable.

Which solar panel installer is the best near me?
In Portsmouth, ReVision Energy, Inc. is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to install solar panels on your roof.
What are the best and worst things about solar power?
A few of the biggest pros are that it lets you spend less on your power bills, it's eco-friendly, and it gives you a good return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels can look clunky on your roof.
How long does it take to see a return on your investment after installing solar panels?
The average payback period for solar panel installation is about 9.8 years, but the exact period depends on the cost of electricity where you are, incentives and net metering programs.
How often do solar panels have to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency after that time.
