Why Spokane Residents and Businesses Are Going Solar
Spokane's energy landscape is shifting rapidly. While Avista Utilities has historically provided relatively affordable hydroelectric-based power, rates have climbed steadily as aging grid infrastructure demands billions in upgrades, wildfire mitigation costs escalate, and Washington's Clean Energy Transformation Act (CETA) drives the transition to 100% clean electricity by 2045. What many Spokane residents don't realize is that Eastern Washington's semi-arid, high-desert climate delivers dramatically better solar resources than Seattle and the Puget Sound region—with 60% more annual sunshine and dry, clear skies from May through October that rival solar production in much sunnier-sounding states. Combined with Washington's exceptional solar incentives including full sales tax exemption and generous net metering, Spokane is quietly becoming one of the best solar markets in the Pacific Northwest.
💰
Steadily Rising Energy Costs
Avista Utilities residential rates currently average 10–13 cents per kWh—historically reasonable thanks to Pacific Northwest hydroelectric resources, but climbing at 4–6% annually as the utility invests in wildfire hardening, aging infrastructure replacement, and CETA compliance. Commercial rates range from 8–11 cents per kWh with demand charges adding significantly during peak winter heating and summer cooling periods. Avista has filed for multiple rate increases in recent years, with the Washington Utilities and Transportation Commission (WUTC) approving substantial increases to cover grid modernization, wildfire prevention, and clean energy transition costs. Solar locks in energy production costs for 25+ years, providing a hedge against decades of compounding rate increases that are structurally baked into Avista's infrastructure investment timeline. A 5% annual increase means today's 12-cent electricity becomes 20 cents within a decade and 32 cents within two decades—the productive lifetime of a solar system installed today.
⚠️
Winter Storms & Wildfire Grid Threats
Spokane's four-season climate exposes the Avista grid to multiple serious disruption threats year-round. Winter ice storms and heavy wet snow regularly snap power lines and down trees across the region—the November 2015 windstorm left over 180,000 Avista customers without power for up to five days, and ice storms in recent winters have caused widespread multi-day outages across Spokane County's older neighborhoods and rural areas. Summer brings a growing and increasingly dangerous wildfire smoke season, with regional fires threatening transmission lines and triggering Public Safety Power Shutoffs (PSPS) as utilities implement proactive de-energization to prevent wildfires during extreme fire weather conditions. Spokane's 2020, 2021, and 2023 smoke seasons degraded air quality for weeks, and wildfire proximity to transmission corridors from the Columbia Basin has caused supply disruptions. Battery storage provides critical backup during both winter storms and summer wildfire events—keeping heating, cooling, air filtration, refrigeration, and medical equipment powered when Avista's grid goes down.
☀️
Exceptional Eastern WA Solar Resources
Here's what surprises most Spokane residents: Eastern Washington's semi-arid, high-desert climate delivers 4.6 peak sun hours daily and approximately 200 sunny days annually—dramatically better than Seattle's marine climate and comparable to solar resources in many Southern states. Spokane's dry, clear summers from May through October produce intense, reliable solar output, while cold winter temperatures actually boost panel efficiency by 10–15% compared to hot-climate installations. Well-designed systems produce 1,200–1,400 kWh annually per installed kW—strong, consistent production that makes solar financially compelling for the Inland Northwest. Spokane's 16+ hours of summer daylight in June provide an extended production window, and the region's low humidity and minimal atmospheric haze allow more direct solar radiation to reach panels compared to humid climates. Eastern Washington genuinely has outstanding solar potential—it just doesn't get the recognition that desert states do.
📋
Washington's Strong Solar Incentives
Washington State offers one of the most generous solar incentive packages in the Pacific Northwest. The 30% Federal Investment Tax Credit covers solar panels, battery storage, and installation costs through 2032. Washington exempts 100% of solar equipment and installation from state and local sales tax—a savings of 8.9% in Spokane (6.5% state + 2.4% local)—one of the most valuable state-level incentives in the country when applied to system costs of $25,000–$40,000. Washington law mandates full retail-rate net metering with Avista, meaning excess solar production earns credits at the full retail electricity rate rather than a discounted wholesale rate. Washington also provides a 100% property tax exemption for solar installations, and the state's CETA mandate (100% clean electricity by 2045) ensures continued policy support for distributed solar. Combined incentives typically reduce net system cost by 40–50% for Spokane homeowners.

Real results from homeowners, contractors, and businesses throughout Spokane County and Eastern Washington.
"We were skeptical about solar in Spokane—everyone thinks of Seattle rain when they hear 'Washington State.' But our installer showed us Eastern Washington actually gets terrific sun, and after two full years our 8.5kW system has exceeded the production estimates every single year. We're banking substantial credits with Avista during the long summer days and using them through winter. Our annual electric bill went from about $2,100 down to $340. Between the 30% federal credit and Washington's sales tax exemption—which saved us nearly $3,000 alone—the system will pay for itself in under seven years. And when the ice storm hit last January and our neighborhood lost power for three days, our Powerwalls kept the furnace, fridge, and lights running the entire time. Our neighbors were in hotels."
Sarah K.Spokane Homeowner, South Hill
"I've been installing solar across the Inland Northwest for five years, and PES has become my go-to supplier. Their PowerLink pricing lets me compete effectively in the Spokane market, and 48-hour shipping means I'm not sitting on expensive inventory. They stock panels and racking rated for our snow loads and temperature swings, and their technical team understands Avista's interconnection process and Washington's net metering requirements. Business has grown 60% year over year—every Avista rate increase and every winter storm that knocks out power sends a new wave of homeowners calling. Eastern Washington is the Pacific Northwest's hidden solar gem, and the market is just getting started."
Ryan T.Solar Contractor, Spokane Valley
"Our medical office building on the South Hill was spending $6,500 monthly on Avista electricity, and the rate increases every year were getting harder to budget for. PES designed a 65kW rooftop system with commercial battery backup that's cut our electricity costs by $4,200 per month—a 65% reduction. The federal tax credit plus MACRS depreciation plus Washington's sales tax exemption recovered over half the investment within four years. But the real value showed during last summer's wildfire smoke event when Avista had to implement rolling curtailments—our battery system kept our patient care systems running without interruption. For a medical facility, that's not just savings, it's patient safety."
Dr. Linda M.Medical Practice Owner, South Hill

Many Spokane homeowners find that monthly solar loan payments are comparable to or less than their current Avista bills—and unlike utility bills, loan payments are fixed and eventually end, while Avista rates will continue climbing year after year. Commercial installations typically achieve positive cash flow within the first year and full payback within 5–7 years.
This is the most common misconception about solar in the Inland Northwest—and it's completely wrong for Eastern Washington. While Seattle and the Puget Sound region do receive heavy cloud cover and rainfall, Spokane's climate is fundamentally different: semi-arid, continental, and separated from Western Washington's marine influence by the Cascade Range. Eastern Washington receives approximately 60% more annual sunshine than Seattle and has a dry, clear atmosphere that allows more direct solar radiation to reach panels.
The numbers tell the story:
Spokane averages 4.6 peak sun hours daily and approximately 200 sunny days per year—outstanding for the Pacific Northwest and competitive with many states considered "sunny"
Well-designed systems produce 1,200–1,400 kWh per installed kW annually—strong, financially compelling production
Summer production is exceptional: May through September delivers dry, clear skies with 14–16+ hours of daylight, producing 55–65% of annual output during these five months
Cold-weather efficiency boost: Solar panels perform better in cold temperatures—Spokane's winter cold provides 10–15% higher efficiency per hour of sunshine compared to hot-climate installations
Low humidity and atmospheric clarity: Eastern Washington's dry air and minimal haze allow more solar radiation to reach panels compared to humid climates at the same latitude
Snow reflection (albedo effect): Fresh snow on the ground around panels reflects sunlight upward, adding 5–8% bonus production during clear winter days
How Spokane compares:
Spokane produces 25–35% more solar energy than Seattle—confirming that Eastern Washington is a fundamentally different solar market
Spokane's solar production is comparable to Portland, OR (which has a robust solar market), and within 10–15% of major Midwestern solar markets like Chicago and Minneapolis
Germany—the world's early solar adoption leader—receives 30% less sunshine than Spokane and built the largest solar industry in Europe
Seasonal net metering makes it work year-round:
Washington's full retail net metering with Avista is the financial mechanism that makes Spokane solar work beautifully across all four seasons. During the long, sunny summer months (May–September), your system produces far more electricity than your home uses—banking substantial credits with Avista at the full retail rate. During the shorter, cloudier winter months (November–February), you draw on those banked credits to offset your electricity consumption. Over a full year, the math works decisively in your favor: summer overproduction credits more than compensate for winter underproduction, and your net annual electricity cost drops by 70–90%. It's a year-round financial system, not a daily one—and Eastern Washington's outstanding summer production is the engine that drives it.
Bottom line: Spokane's solar resources are dramatically better than most people assume. Eastern Washington is the Pacific Northwest's hidden solar gem—outstanding sunshine, cold-weather efficiency advantages, one of the country's best net metering programs, and Washington's exceptional sales tax exemption make it one of the most compelling solar markets in the region.
