Residential Solar Panels in Seattle: Cost and Installation Guide

Blog Solarize Washington (13)


Harnessing the power of the sun for energy is a growing trend in Seattle. As more residents adopt solar energy, understanding the cost and installation process becomes crucial. This comprehensive guide provides an overview of residential solar panels in Seattle, focusing on cost and installation aspects.

Solar Panel Costs in Seattle

The cost of solar panels depends on a variety of factors, including the size and type of the system, the complexity of the installation, and the solar company you choose. On average, the cost of solar panels in Seattle ranges from $12,000 to $25,000 after federal tax credits. This can translate to an average cost of around $2.50 to $3.50 per watt.

However, it’s important to consider that these are upfront costs. Over time, the energy savings provided by your solar panels can offset this initial investment. With net metering policies in place, any excess energy your system produces can be sold back to the grid, further reducing your overall energy costs.

Federal Tax Credit

One of the most significant incentives for going solar is the federal solar tax credit, also known as the Investment Tax Credit (ITC). This incentive allows homeowners to deduct a percentage of their solar costs from their taxes. As of writing, the ITC stands at 26% but is scheduled to drop to 22% in 2023.

Installation Process

Assessment and Design

The first step in the solar installation process is a site assessment. The solar company will evaluate your home’s suitability for solar, taking into account factors such as roof condition, shading, and the direction your home faces.

Next comes the system design. The solar company will work with you to design a system that fits your energy needs and budget. They’ll also help you understand the potential savings and payback period for your system.

Permits and Paperwork

Once the design is finalized, the solar company will handle the necessary permits and paperwork. This includes building and electrical permits and interconnection applications with your utility.


The actual installation of your solar panel system typically takes one to three days, depending on the size of the system. After installation, an inspection by the local building department and your utility is required before your system can be connected to the grid.


Following a successful inspection, your system can be activated. At this point, you’ll start generating your own clean, renewable energy.


Investing in solar panels for your Seattle home can result in substantial energy savings and reduce your carbon footprint. While the upfront cost may seem significant, federal tax credits and long-term energy savings make solar power a financially savvy choice. By understanding the cost and installation process, you can make an informed decision about whether solar power is right for your home.
