The Cost and Benefits of Solar in Londonderry

For many people, the decision of which solar installer to hire depends on costs. Some important factors that dictate how much it will cost to install a solar panel system on your home and how much money you could save over time are:

  • How much energy you use: If your family regularly uses a lot of energy, you'll benefit more from going solar.
  • How much you spend on energy: The typical family in Londonderry spends around $1,000 a year on energy alone, so you could gain that much in savings.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 26% of the project cost. Your state may also have incentives and rebates that you can take advantage of. In addition, you can save about $20,000 over 20 years on your utility bills, before factoring in incentives.
  • Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.

Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, including the size of your house and your current power bills.
