General Solar Questions
How does solar power work?
Solar panels convert sunlight into electricity using photovoltaic (PV) cells. That electricity can power your home or business, reducing your reliance on the grid and lowering your utility bills. Learn more about the history of solar energy and how solar technology has evolved.
Are solar panels effective in Washington State?
Yes. Despite our gray skies, solar panels in Washington State perform very well thanks to long summer days, cool temperatures (which improve efficiency), and net metering policies. We design systems specifically for the Pacific Northwest climate.
What are solar incentives available in Washington?
Solar incentives include the 30% Federal Tax Credit (ITC), Washington State sales tax exemption on eligible systems, and net metering programs through local utilities. These programs make solar more affordable for homeowners and businesses alike.
Residential Solar Questions
How much do residential solar panels cost in WA?
The cost of residential solar panels in Washington State varies depending on system size, roof type, and equipment. Contact us for a free consultation to estimate your savings by switching to solar.
What’s the best solar battery backup system for home use?
Popular home battery companies include Tesla Powerwall, Enphase, and Franklin. We’ll help you choose the best solar battery backup system for home based on your energy needs and budget. We’ll also help you navigate incentives such as Puget Sound Energy’s (PSE) Flex Batteries Program.
Do I need a solar battery backup system?
While not required, many homeowners add a solar battery backup system to stay powered during outages. Battery storage adds resilience and allows you to store energy for use at night or during emergencies.
How do I clean or wash my solar panels?
In most cases, rain does the job. If needed, gently rinse with a hose and soft brush. Avoid abrasive tools or pressure washers. For tips, check out our guides on how to clean solar panels and how to wash solar panels.

Commercial Solar Questions
What are the benefits of commercial solar installation?
Commercial solar energy systems help businesses reduce operating costs, hedge against rising utility rates, and meet sustainability goals. Systems often pay for themselves through energy savings and incentives.
How much energy will a commercial solar system generate?
Production depends on location, orientation, shading, and system size. For example, a 15kW solar system with battery backup can cover a significant portion of a medium-sized business’s daytime load.
What is included in a commercial solar installation?
We handle everything in-house: system design, permitting, utility approvals, installation, and long-term support. We also offer commercial solar maintenance and monitoring to ensure long-term performance.
How do I choose between commercial solar companies near me?
Look for experience, local knowledge, and full-service support. Ecotech Solar has installed hundreds of commercial solar panels in Washington and offers tailored solutions for each property.
Can I finance a commercial solar installation?
Yes. Commercial clients can take advantage of federal tax credits, MACRS depreciation, and financing options. We help identify the best financial model for your business.
Net Metering & Incentives
What is net metering in Washington State?
Currently, net metering in Washington State allows solar system owners to receive a 1-to-1 credit on their electric bill for excess energy sent back to the grid. Credits roll over monthly and reset annually.
Is net metering available for both residential and commercial customers?
Yes. Most utilities in Washington offer net metering for systems up to 100 kW. This applies to homeowners, nonprofits, farms, and commercial properties.
Are there rebates for installing solar panels in WA?
While Washington no longer offers state rebates, residents can still benefit from the 30% Federal Tax Credit, WA sales tax exemption, and net metering. These combined incentives significantly reduce upfront costs.
System Sizing & Performance
How do I know what system size I need?
We offer free site assessments to determine the ideal system size based on your past electric usage, roof size, and shading. Popular systems include 5kW for homes and 15–100kW for commercial properties.

Yes. We offer both solar system battery backup and standalone battery options. Our systems are scalable—from homes to full-scale commercial properties.
