The Cost and Benefits of Solar in Londonderry
Even though solar panels can save you money on energy bills over time, it's important to consider the startup costs. The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:
- Incentives: Those who buy and install a solar system this year can save 30% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $20,000 on your energy bills over 20 years not including incentives.
- The type of solar panel system you can afford: This depends on what your budget is.
- Your home's power bills: Due to fairly high monthly power bills in Londonderry, you could save about $1,000 a year with solar.
- Electricity consumption: The average household in Londonderry doesn't use much energy, and therefore may not see as many savings on their power bills.
Solar is a rewarding investment for most homeowners. You can generate your own electricity instead of paying for it from a utility company and make use of solar incentives and rebates, all while helping preserve the environment.
