The Cost and Benefits of Solar in Derry
The cost of putting up solar panels has decreased significantly in the past few years, but it's still a significant investment for most homeowners. Some key things that determine the upfront cost and potential savings over time include:
- Electricity consumption: The average household in Derry doesn't use much energy, and so may not see as many savings on their power bills.
- Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- Your power bills: This will dictate your savings. In Derry, the average resident can save about $1,100 a year on their electricity bills.
- Incentives: Those who buy and install a solar energy system this year can save 26% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $21,000 on your utility bills over 20 years excluding incentives.
Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on a number of factors, like the amount of daily direct sunlight available and your energy consumption.
