Solar Contractors in Seattle, Washington
Solar panel installation and solar energy systems..
Solar contractors design and install photovoltaic (PV) systems for residential and commercial rooftops, as well as ground-mounted arrays. A typical residential solar system (6–10 kW) offsets 70–100% of electricity usage depending on roof orientation, shading, and local sun hours. The federal Investment Tax Credit (ITC) currently provides a 30% tax credit on the total installed cost, and many states and utilities offer additional rebates. Reputable solar installers handle the full process: site assessment, system design, permitting, installation, utility interconnection, and warranty support. Lease vs. purchase vs. loan financing each have different long-term economics.

General Solar FAQs
How much do solar panels cost?
Residential solar systems cost $2.50–$3.50 per watt installed before incentives. A typical 8 kW system costs $20,000–$28,000 before the 30% federal tax credit, bringing the net cost to $14,000–$19,600. System size depends on your electricity usage, roof orientation, and shading. South-facing roofs with minimal shading produce the most energy. The payback period is typically 7–12 years depending on local electricity rates and net metering policies. After payback, the system produces essentially free electricity for 15–20 additional years.
Should I buy or lease solar panels?
Buying (cash or solar loan) provides the highest long-term return because you own the system, claim the 30% federal tax credit, and keep all energy savings. A solar lease or PPA (Power Purchase Agreement) requires no upfront cost but you pay the leasing company for the electricity produced at a fixed or escalating rate, and you don't get the tax credit. Buying typically saves $10,000–$30,000 more over 25 years compared to leasing. Leasing can complicate home sales since the lease transfers to the buyer. Most financial advisors recommend buying if you can afford the upfront cost or qualify for a solar loan.
