Summary of Rhode Island solar incentives 2021
There are two huge factors working to boost home solar in Rhode Island: the state's Small-Scale Solar grant program and the Renewable Energy Growth Program. Combined, they mean you'll save thousands up front on a new solar system and can sell the electricity it produces for thousands more.
Solar is cheaper than ever, so the Rhode Island incentives combined with the Federal 26% tax credit for solar means a solar panel system pays itself back quickly and makes you lots of money over its 25-year warrantied life!
On this page, you can:
-
Learn what solar incentives are available to Rhode Island homeowners
-
See what Rhode Island solar incentives you qualify for based on your utility company and city
-
Find out how much these incentives and/or Rhode Island solar tax credits will reduce your cost to go solar and add batteries
Federal solar investment tax credit
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Rhode Island
This perk is commonly known as the ITC, short for “Investment Tax Credit”. If you install your photovoltaic system in 2020, the federal tax credit is 26% of the cost of your solar panel system. This is 26% off the entire cost of the system including equipment, labor and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 26% = $5,200.
The federal tax credit falls to 22% at the end of 2022.
Net energy metering in Rhode Island
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.
Rhode Island has a strong net metering program that ensures you get credit for your surplus energy production -- up to 125% of your monthly consumption. Surplus is credited to you at the utilities avoided-cost rate, and may be either carried forward to the next bill or purchased by the utility, at their discretion.
After 2016, the legislature doubled the net metering limit to 10 Megawatts of total generation capacity, and also added net metering for 3rd-party-owned systems.
That’s a pretty solid law overall, but there are definitely some easy tweaks the legislature could implement to make net metering even stronger. For one, municipal and cooperative electric companies are currently exempt from the statewide net metering standards. The law should be expanded to cover all utilities.
We’d also like to see the option for bill rollovers or cash payments moved from the utility to you, so you can decide how the savings help you most.
Rhode Island solar rebates
While Rhode Island does not have a dedicated state rebate for solar panel installation, some manufacturers like LG offer their own solar rebates. These programs are usually time sensitive. For example, LG offers a $600 solar rebate on their equipment, which your installer can help you redeem over the next year.
Solar performance payments
National Grid’s Renewable Energy Growth program in Rhode Island provides an awesome incentive to go solar. You get a performance based incentive (PBI) payment which is reflected both as a credit to your monthly electric bill and as a cash payment every month.
For 2021, you can expect the PBI to be at $.25- $.29 cents per kilowatt-hour (kwh). The PBI gets split between a credit to your existing electric bill and that cash payment. Since an average 6-kW home solar system generates about 10,000 kwh annually, you can expect bill credits and payments of $2,500 annually for a term length of 15-20 years! Even though the cash portion of the PBI is taxable income (meaning you’ll get an IRS 1099 form), this program is a huge boon to you for installing solar.
Solar grant program
Rhode Island policymakers also created a fund for those who may not be sure if they’re going to live in their homes for the next 20 years to go solar as well. If you decide not to participate in the PBI above, you can elect to take a solar grant from the Rhode Island Renewable Energy Fund instead.
For 2021, the grant amount is up to $850 per kilowatt of installed solar, up to a maximum of $7,000. On an average 6-kW system, that amounts to $5,100 upfront! This solar grant program is among the best in the nation. Way to go, Rhode Island!
Tax exemptions
Thankfully there are tax exemptions for solar power here as well. When you install a solar power system, your home goes up in value by a factor of 20 times your electricity bill savings. No one should ever be penalized for converting to renewable energy, a sentiment with which the Rhode Island legislature agrees.
That’s why they passed a property tax law ensuring that your solar power system will never be assessed at any higher value than the equivalent standard, non-renewable energy production system. That means all that increase in value you get from a solar power system over a conventional system stays with you and not with the state tax collectors.
Those shiny new solar panels are also 100% exempt from all sales and use taxes when you purchase and install them.

I spoke with Mark regarding my solar project at home and he was able to explain the system and how it will meet my current demand. He explained upfront costs and options. The master electrician Mike Richards was very professional and installed the system after consulation with me for the best location for the wiring. I would recommend it to others for your solar panel needs. Thanks.

I've was looking for a solar company for a about 10 years. I was finally convinced by Rob from Sunergy , with a nice design that would make more than I use. And he delivered. The team that installed it did a very professional job, despite being in the 90's . Now I am very proud of producing all clean electric power. Nice job Sunergy.

I highly recommend Sol Power. Every step of the way, they were professional, above-board, and efficient in their planning, installation, and wrap-up process. We even got the installation finalized through the pandemic! Plus they are cooperative, which keeps the money in the community.

The sales process was great. They were very attentive and offered the best deal on the best equipment. Then.. After signing the deal, they stopped returning e-mails and phone calls. It took them 6 months to get the materials delivered. Then it took 2 weeks before installation started. And the meter was installed incorrectly. They corrected that quickly as I was still holding the final 10% progress payment and their sales team was back to calling and e-mailing every other day. 4 years in, one of the micro-invertors stopped working. For 4 weeks, no one at RGS responded to my calls; e-mails; or web-chats. I initiated the replacement part request with the manufacturer and the next day RGS e-mailed me back to say a replacement part had been ordered and should be arriving in 2-4 weeks. I got the part in 4 weeks, notified RGS, and, again, they went silent on me. 4 weeks after that, I got an e-mail from RGS with a workorder stating that I would have to pay $350 plus additional costs for them to complete the work under warranty. That is where we stand now. If I had to do it again, I would go with a company that had positive reviews after the sales process. That is when you are going to need them they most. Good luck with your solar projects.

Working with Greenside Energy was an unbelievable experience. We got a half dozen proposals from installers before we pulled the trigger. Greenside didn't just sell us a solar system but educated us about all the componets like the inverters, power optimizers, snd solar panels. They set us up with an amazing web based monitoring portal so we are able to track our power production in real time. After The install was complete they used their quad copter to take an aerial photo of our system which we have hung up in our office! I would highly recommend giving them a call.<br /><br />West Main Self Storage Team

This company is ethical and has the integrity to take your solar project from the start to the finish line, while holding your hand every step of the way and ensuring you understand what is happening and how the process works. <br /><br />I was very impressed with Joe's ability to explain the benefit of solar, and his passion for protecting the environment. I have already referred 3 friends to Nuera Solar, which Nuera Solar paid me a 'referral fee' for doing so on each friend.<br /><br />If you're looking to go solar in New England, look no further than Nuera Solar
