New Hampshire is a state that got solar right pretty early. The General Court passed a strong Renewables Portfolio Standard back in 2007, and with it came a good statewide rebate program to lower the up-front price of solar. It's now almost a decade later, and the state still has decent rebates and net metering, which are the major reasons solar is a great investment.
The average cost for an installed residential solar system in New Hampshire is currently $12,556 after claiming the 26% federal solar tax credit. This is $2.83 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 2020 they also remain subsidized by the 26% 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 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 New Hampshire is now.
New Hampshire law requires utilities to offer their customers net metering. Under this law, net metering can be offered in one of two ways:
If you opt for getting paid out at the avoided cost rate, you will receive a check for your excess energy. However, while it would be nice to receive a check, you will actually save more if you choose the one-bill kWh credits because kWh credits are equal to the full retail value of electricity.
New Hampshire has a renewable portfolio standard that requires utilities to derive 19.7% of their energy from renewable sources, and 0.60% of that must come from solar energy systems.
In order to meet these goals, utilities must obtain SRECs, which represent the environmental benefits of producing 1 megawatt-hour of electricity from solar. Because of the solar energy target, New Hampshire has created a market for SRECs, in which one SREC can be sold for a maximum price of $57.15.

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2020 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.
Solar panels are mounted on your roof and wired together in groups called solar arrays. The power they generate flows into a solar inverter, where the direct current (DC) is converted into alternating current (AC). The electricity is then either used by your home or exported to the electric grid.
Off-grid solar power involves meeting all your energy needs from the sun; there’s no utility to fall back on. The solar installation needs to power your home not just during the day, when the sun is shining, but after dark as well. This requires many solar panels, paired with a large battery system.
In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. This 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.

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 New Hampshire will fall during 2020.
Depending on the location, solar panels will generate different amounts of electricity.
A solar system that is installed on a south-facing 33-degree pitch roof New Hampshire will generate 1,150kWh of peak DC (direct current) capacity per year per 1kW in New Hampshire.

The advantage of installing solar panels in New Hampshire is that there are both state-based incentives and the federal tax credit. In addition, New Hampshire has expensive power. This means that the overall return on investment for an installation of residential solar panels here is one of the best in the nation.
One disadvantage of installing solar panels for your home in New Hampshire is that there is less overall sunshine per year, so a solar system here will produce less electricity than a system in sunnier states, like Arizona, would. However, the available incentives more than make up for what the state lacks in sunshine, making installing solar panels in New Hampshire a great investment for homeowners… for now.
Several times over the last two years, state lawmakers passed bills to expand New Hampshire’s net metering rules. However, governor Chris Sununu has vetoed all of them. Things are still good for people who want to go solar in New Hampshire, but will soon be less rosy without action from the governor. For 2020, strong with its rebate program, and decent low income solar programs, New Hampshire holds steady as a good state for solar.

A solar carve-out is a law that sets a specific goal for electricity generation from solar panels. Solar carve-outs in the United States often include incentives that reward solar owners for the energy their panels generate. The incentives can be worth th
