Prices based on a 5.8kW system, after 26% federal tax credit
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 Idaho is now.

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.
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.
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.

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 Idaho 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 27-degree pitch roof Idaho will generate 1,150kWh of peak DC (direct current) capacity per year per 1kW in Idaho.

The biggest advantages in Idaho for installing solar panels are the state tax credit and the 26% federal tax credit. These two incentives alone make solar an excellent investment for your home.
There are not many disadvantages to installing solar panels in Idaho. However, Idaho doesn’t offer a sales or property tax exemption on solar energy equipment like many other states do.
If you’re a homeowner in Idaho, you’ll be kicking yourself that you didn’t get solar while these incentives were still around.
