Get answers to common questions about home solar services in Longview, Washington.
Solar panels are very effective in Longview's climate. Modern panels generate electricity from daylight, not just direct sunlight, and they perform efficiently in cooler temperatures. While summer months yield peak production, systems are designed to generate significant annual savings, and Washington's net metering policy allows you to bank excess summer credits to offset your winter usage.
After the federal 26% tax credit, a typical 6kW system in Longview ranges from $15,000 to $25,000, depending on your roof and equipment. Key incentives include the federal Investment Tax Credit (ITC), Washington's sales tax exemption on solar installations, and the state's generous net metering program. Cowlitz PUD also offers a specific interconnection process for seamless grid connection.
Yes, you will need a building and electrical permit from the City of Longview's Community Development Department. Your chosen installer will typically manage this process. Importantly, Longview and Cowlitz County do not have restrictive homeowners association (HOA) solar regulations, as Washington state law (RCW 64.38.055) prohibits HOAs from unreasonably restricting solar installations.
Look for providers with strong local experience, proper Washington state electrical licenses (like an L&I electrical administrator license), and positive reviews from Longview or Cowlitz County residents. Ask for local references and ensure they are familiar with Cowlitz PUD's interconnection requirements. A trustworthy installer will provide a detailed production estimate specific to Longview's weather patterns.
Maintenance is minimal; seasonal rain usually keeps panels clean. You may need to clear light snow, which often melts quickly due to the panel's dark surface and angle. A key local consideration is tree trimming, as Longview's many tall trees can cause shading. Ensuring panels have clear exposure, particularly to the south, is crucial for maximizing production year-round.
