Generate clean energy on your property with grid-tied or off-grid solar systems. Site assessment, permitting, installation, and net metering setup. Reduce electricity costs and increase property value.
Get Solar QuoteEastern Washington's 300+ sunny days per year make solar energy highly productive. Solar panels reduce electricity costs, provide energy independence, and qualify for federal tax credits (30% ITC through 2032). Rural properties benefit from net metering agreements with utilities, earning credits for excess power sent to the grid.
TerraVector coordinates residential and agricultural solar installations: site assessment for optimal panel placement, electrical design, building and utility permits, installer selection, and interconnection agreements. We work with grid-tied systems (with net metering) and off-grid systems (with battery backup) depending on your location and needs.
Evaluate roof or ground mount location for solar exposure, shading, and structural capacity.
Size solar array based on electricity usage, available space, and budget. Select panels and inverters.
Obtain building permit and electrical permit. Submit utility interconnection application for grid-tied systems.
Licensed electricians mount panels, install inverters, run conduit, and connect to electrical panel.
County electrical inspector and utility verify installation. System activated and begins generating power.
Set up monitoring app to track production. File for federal tax credit and utility incentives.
Residential systems (5–10 kW) cost $15,000–$30,000 before incentives. After 30% federal tax credit, net cost is $10,500–$21,000. Larger systems for farms or commercial properties (20–50 kW) cost $50K–$120K. Ground-mount systems cost 10–20% more than roof-mount due to racking and trenching.
Modern solar panels are warrantied for 25 years and typically produce 80–90% of original output after 25 years. Inverters last 10–15 years and should be budgeted for replacement. With minimal maintenance (occasional cleaning), solar systems generate power for 30+ years.
Yes. Eastern Washington receives 280–310 sunny days per year — excellent for solar production. Panels actually work more efficiently in cooler temperatures. Winter production is lower due to shorter days and snow, but annual production is strong. West of the Cascades sees 40–50% less production due to clouds.
Net metering allows you to send excess solar power to the utility grid in exchange for credits. When your panels produce more than you use, your meter runs backward. You use those credits when consuming power at night or during winter. Most Washington utilities offer net metering programs.
Roof-mount is cheaper and uses existing structures. Best for homes with south-facing roofs in good condition. Ground-mount costs more but offers optimal panel angle, easier maintenance, and unlimited capacity. Ideal for rural properties with land and aging roofs.
Not for grid-tied systems — the utility grid acts as your backup. Batteries (like Tesla Powerwall) cost $10K–$15K each and provide backup power during outages. Useful for off-grid properties or locations with frequent power failures. Battery costs have been dropping steadily.
Federal: 30% Investment Tax Credit (ITC) through 2032. Washington State: no state income tax, so no additional state credit. Utilities: Some offer upfront incentives or production incentives. Check with your utility for current programs. Property tax exemption for solar installations.
We coordinate solar installations across central and eastern Washington: Grant, Adams, Douglas, Lincoln, Franklin, Okanogan, Spokane, Kittitas, and Chelan counties.
