The Cost and Benefits of Solar in Princeton
For many readers, the decision of which solar company to hire depends on costs. Some key things that impact the cost and possible savings include:
- How much power your household consumes: Households that use a lot of power each month may call for more solar panels and, as a result, be more expensive, but will also save more on their energy bills over time.
- The type of solar panel system you have the money for: This depends on how much you're willing to invest upfront.
- Incentives: Those who purchase and install a solar energy system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $14,000 on your electricity bills over 20 years not including incentives.
- Your energy bills: This will determine how much money you might save. In Princeton, the average homeowner can save about $970 a year on their electricity bills.
Solar is a valuable investment for most homeowners. You can generate your own power instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping preserve the planet.
