Rhode Island has some of the best incentives in the nation when it comes to installing solar. The state offers a very generous performance-based incentive that is equal to $0.2845 per kilowatt hour produced and an upfront rebate of $0.90 per watt installed that can help reduce installation costs.
The average cost for an installed residential solar system in Rhode Island is currently $11,311 after claiming the 30% federal solar tax credit. This is $2.69 per watt. However, there is some variance in solar prices in different parts of the state. The graph below shows the average cost of installed solar systems in your part of the state.

Solar panels have fallen in price by more than 80% in the last ten years. In 2022 they also remain subsidized by the 30% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.
Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

The most significant incentive to install solar panels for homes and businesses in Rhode Island is the federal solar tax credit. At the end of 2020, the amount of the credit will decrease from 26% to 22% of the cost of the solar installation.
Because home and business owners want to get the largest incentive amount possible, solar panel installation companies will likely be flooded with new projects before year’s end. In order to maximize your savings potential, the best time to go solar in Rhode Island is now.
Rhode Island policy requires utilities to compensate customers when their solar system produces more electricity than they use. In other words, for each excess kilowatt-hour, your system produces, your utility has to provide a credit to you that is equal to the avoided cost rate of electricity.
The Rhode Island Renewable Energy Fund is a grant program that has the potential to cover up to 30% of the total costs of solar projects. Through the program, you can receive $0.90 per watt of solar that you install, up to $7,500. That’s a huge solar market incentive that can significantly lower the payback period for your solar system.
The Renewable Energy Growth Program is a very unique program with the goal of promoting renewable energy system installations. When you sign up for the program, you will receive a rebate of $0.2845 per kilowatt-hour (kWh) of energy your system produces. What makes this program unique is that before you receive the incentive, you first receive an electric bill credit, and then you get the remainder of the incentive.
When a solar energy system is installed on a home, the value of the property goes up, and so do the property taxes. Rhode Island residents don’t have to worry about this tax hike, thanks to the state’s property tax exemption for renewable energy resources. The law exempts 100% of the assessed value of a solar array from a homeowner’s property taxes.
Rhode Island law prevents the state’s 7% sales tax from being applied to the sale of solar energy equipment. In some cases, sales tax can accumulate to over $1,000, so this exemption saves you a lot more than you might think.

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2022 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.
A grid-tied system is the most common type of solar system. It has no solar battery for backup power and utilizes net metering to maximize savings. Solar panels are mounted on your roof then wired together, and the power generated flows into an inverter where direct current (DC) electricity is converted into alternating current (AC) electricity. This electricity is either used by your home or is exported to the utility grid.
In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. The solar electricity generated by your panels that your home does not use is stored in the battery instead of being sent to the grid, which reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.
Off-grid solar systems are not connected to the grid at all, so all of your energy needs must be met by the sun. There is no utility to fall back on. The solar installation needs to power your home not only during the day, but after dark as well, so many solar panels and a large battery system are required. These systems are often expensive and don’t make sense for homes that have access to the grid.

No, but cleaning them can improve power generation if they are dirty.
Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Rhode Island will fall during 2022.
Depending on the location, solar panels will generate different amounts of electricity.
A solar system that is installed on a south-facing 31-degree pitch roof Rhode Island will generate 1,168kWh of peak DC (direct current) capacity per year per 1kW in the Providence area.

The advantages of installing solar panels in Rhode Island include both the state-based incentives and the federal tax credit. Also, Rhode Island has some of the highest electric utility rates in the nation, thereby making the overall return on investment for residential solar panels in Rhode Island outstanding.
The disadvantage of installing solar panels for your home in Rhode Island is that there is less overall sun exposure in the state per year, so a solar system produces less here than it would in a state such as Arizona. In addition to that, Rhode Island’s net metering policy does not require utilities to credit you for excess generation at the full retail rate, meaning your excess energy will be credited at a slightly lower price.
However, the state incentives more than make up for these shortcomings. Rhode Island homeowners will be kicking themselves if they don’t install solar panels while these generous incentives are around.
