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 tax credit. Right now, the federal tax credit is equal to 26% of the total installed costs of installing a solar system. At the end of 2020, the amount of the credit will fall to 22%. This means that in order to maximize your savings potential, the best time to go solar in Maine is now.
Maine has a state-wide net metering policy that requires all private and public utilities to pay their customers the full retail rate for each kilowatt-hour of power generated by their solar panels.

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2021 "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 Maine will fall during 2021.
Depending on the location, solar panels will generate different amounts of electricity.
A solar system that is installed on a south-facing 30-degree pitch roof Maine will generate 1,550kWh of peak DC (direct current) capacity per year per 1kW in Maine.

The advantage of installing solar panels in Maine is the mandatory net metering law. Maine has high electricity rates, which means homeowners will save big on their utility bills, thanks to net metering.
The disadvantage of installing solar panels in Maine is that there is very little in the way of state and utility-based incentives.
However, because of the federal tax credit, now is the best time for Maine homeowners to make the switch to solar.
