The Cost and Benefits of Solar in Plymouth
When deciding on a solar company, most homeowners or business owners wonder about the costs the most. The cost and possible savings vary depending on a few key factors such as:
- Incentives: Tax-paying citizens who purchase and install a solar energy system this year can save 26% of their installation costs by using the federal solar investment tax credit. You can also save about $24,000 on your energy bills over 20 years excluding incentives.
- The amount of sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panels won't be able to produce as much energy, which will leave you with lower savings on energy bills than a roof that gets lots of sunlight.
- Energy consumption: Installing a solar system may be too pricey an investment for households that don't need a good amount of energy a month.
- The kind of solar panel system you can purchase: This depends on what your budget is.
Though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on several factors, including the size of your house and your energy consumption.

Environmental Impact of Switching to Solar in Plymouth
If you're thinking of adding solar panels to your home, one of the principal reasons why may be to lower your reliance on nonrenewable energy. Something many homeowners might be asking themselves is how much can they really help save the environment by switching to solar power anyway? Switching to solar power is an impactful choice for the environment, due to the fact that the greatest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation — all of which can be powered by solar instead. In fact, if you make the switch to solar power, you could reduce your carbon dioxide emissions by about 40 pounds each year. As you can see, trading traditional energy for solar has so many other perks beyond saving money. One of the main ones is that you can help save the environment too.
