The Cost and Benefits of Solar in East Greenwich

For most homeowners, whether or not to invest in a solar energy system boils down to the cost. Some significant things that impact the upfront cost and potential savings over time include:

  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: Tax-paying citizens who purchase and install a solar system this year can save 26% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $20,000 on your utility bills over 20 years without incentives.
  • Your power bills: This will affect your savings. In East Greenwich, the average resident can save about $880 a year on their electricity bills.
  • How much electricity your home consumes: Households that consume lots of energy each month may need more solar panels and, as a result, be more expensive, but will also benefit more over time.

There are many wonderful benefits of solar despite the upfront cost of installation. It can help the Earth and your wallet. Additionally, it can boost the value of your home, giving you even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in East Greenwich

If you're considering adding solar panels to your home, one of the main reasons why may be to reduce your greenhouse gas emissions. You may be trying to figure out — how much does making the switch do for the environment anyway? Switching to solar power is a sustainable choice for the environment, due to the fact that the largest 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. If you go solar, your carbon dioxide emissions can be lowered by about 40 pounds each year. If you want to do your part for the environment, you'll likely get that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.
