What a great 2019 State legislative session we had for solar energy! Washington State has a new solar incentive program that rewards homeowners 6.5% to 10.4% for going solar in the form of a sales tax exemption! For a typical sized system this is a $2,000 incentive. The exemption is included in the 100% Clean Energy Act which was signed into law on May 7. All solar systems installed after June 30th, will be 100% exempt from State sales tax, resulting in a lower solar system cost and a faster payback.
