The Cost and Benefits of Solar in Greenville
We understand that for many homeowners, the choice to invest in solar hinges on installation costs. The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $20,000 over 20 years with your solar panels, too.
- How much you spend on energy: The average family in Greenville shells out around $880 a year on energy use alone, so you could be looking at that much in savings.
- The make and model of solar panels you want: More high-tech panels have higher prices, so that will shape your budget for your solar project.
- Energy consumption: Installing solar panels may be too steep of an investment for families that don't consume a good amount of energy a month.
As a result of the cost of solar panels being lower than before as well as several solar incentives, they are a solid investment for the majority of homeowners.

EcoWatch's Greenville, RI Solar Company Rankings FAQs
Which solar company is the best in Greenville?
The best local solar company in Greenville is Prime Energy Solar, with a rating of 5.00 stars.
What are the major advantages and disadvantages of adopting solar power?
The biggest advantages of solar power are that it can reduce or, in some cases, entirely eradicate your electricity bills, improve your home's value and reduce your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not save as much if you don't use a lot of electricity and it doesn't work for all roof types and locations.
How long does it take to see a return on your investment after installing solar panels?
Solar panels typically pay for themselves in about 9.4 years, but your solar payback period will depend on your utility costs. The more your typical power bill, the quicker your solar panel system will pay for itself.
How long do solar panels last?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is their energy production will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
