Washington has focused on green building initiatives, providing funding for new housing for low income families with solar systems through the Housing Trust Fund. The state has also enacted a 43% tax abatement for businesses involved in manufacturing photovoltaic modules, solar grade silicon and similar devices and components used solely in solar energy systems. Additionally, there are grants and other incentives available.
The King County-LEED Grants program offers a grant of up to $30,000 for new construction or major renovation which results in LEED certification. Seattle / King County – Built Green Grant Program provides similar grants up to $20,000 when certified four or five star in the Built Green program. Schools in Washington State are fitted with solar collectors paid 100% by the Solar 4 R Schools program, a private initiative.
Washington State exempts sales tax on the purchase of equipment used to produce solar power, as long as the system is at least 1kWh, and also applies the exemption to solar water heaters.
There are five different incentive programs, up to $5000 annually, available to producers of solar power. These incentives are calculated by the kWh, ranging from $.12 to $1.50.
