Washington State Solar Incentives & Rebates

30% Federal Solar Investment Tax Credit (ITC)

The federal solar tax credit, or also known as the Investment Tax Credit (ITC), increases the development of solar power in our everyday residential and commercial lives. This tax credit for solar panels reduces your federal tax liability on a dollar-to-dollar basis. There is no upper limit to how much tax credits you can get. It is worth 30% of your final project cost.



How Does The Federal Solar Tax Credit Work?

When you receive your final invoice, you’ll claim 30% of the final cost in federal solar tax credits on the same year's taxes. For example, when the final cost to install solar panels is $10,000, you will receive $3,000 (30%) back in federal tax credits. Don’t have the tax appetite? You may use the credits up to 5 years after the tax year of installation.


Solar Net Energy Metering (NEM)

Net Metering in Washington state is how your utility compensates you for providing clean, renewable solar energy to your neighbors and grid. After you switch on your new solar energy system, your utility will begin to spin your meter backward when you're producing more (solar) energy than how much energy your home is consuming! Each time you send excess power to the grid, the solar energy gets used nearby (by your neighbors) and you accumulate energy credits.


How Does Net Metering Work?

For example, if your solar panel system generates 1,000 kilowatt-hours of solar power in the month of May while you consume 650 kilowatt-hours of energy earning you 350 energy credits. These energy credits get used when you’re not generating more solar power than using (at night, etc).

By combining free, renewable power with the new Washington state solar production incentive and healthy tax credits business are choosing solar energy to realize short and long-term benefits for all sizes of businesses.



MACRS Accelerated Depreciation

Depreciation is the loss of value that occurs over time with the item your business purchased for a specific use. As a business owner, you are eligible to deduct this “loss in value” from your taxable income when used for your business. 85% of total solar installation costs are eligible for depreciation. This can add a tremendous amount of financial value to your system. Our example tables below use a project cost of $100,000.

50% Bonus Depreciation is available

In the first year claiming the 50% Bonus Depreciation, the basis is reduced by half or 50% from $85,000 to $42,500 before applying the normal MACRS depreciation rate. In Year One, you will gain an addition $8,500 in depreciation ($42,500 x 20% = $8,500). After year one, you will continue to apply MACRS rates to the remaining half of the basis ($42,500 x 32% =$136,000 and so on…)

Net Energy Metering (NEM)

Net Energy Metering is how your utility compensates homeowners with solar panels for providing clean, renewable energy to your neighbors. Your utility must keep a “running tab” on how much solar energy you generate and then remove that charge from your bills. Any extra electrical credits that you save up must be carried forward to the next month’s bill for a full year.


Each credit is worth equal the market rate which is the price you pay for electricity.This means that you can bank up energy credits for solar power that you create in the summer, then use it in the winter when the sun isn’t shining so much.

Example of Net Energy Metering

You generate 10,000 kilowatt-hours of solar power. You consume 6,050 kilowatt-hours of utility energy. Therefore, you net 3,500 energy credits.
