Wondering if harnessing all this summertime Vitamin D for lower electricity bills makes sense before OLD MAN WINTER returns? Well faster than you can binge watch iZombie, I‘ll break things down point-by-point so you can decide if solar works on your budget.
We‘ll cover everything from upfront installation costs, incentive savings, ideal system sizing and even project out long-term energy offsets. So grab a Rainier tallboy and let‘s crunch some numbers!
Solar Panel Cost Considerations in the Evergreen State
While overall Washington isn‘t exactly Arizona when it comes to sun…the eastern plains see their share of cloudless days! And even typically overcast stretches west of the Cascades get enough daylight to make solar viable.
But varying conditions across the state impact how many panels you need – and what they‘ll cost. I‘ve summarized key factors influencing system pricing right here:
Regional Weather Conditions
| City | Avg Sun Hours | Avg Temp | Panel Output Modifier |
|---|---|---|---|
| Seattle | 3.99 | 51.4 °F | -15% |
| Spokane | 5.55 | 48.8 °F | 0% |
| Yakima | 6.48 | 55.2 °F | +10% |
As shown above, Eastern WA locales like Yakima get nearly 30% more sun exposure – meaning solar panels produce more energy to offset electricity bills. So an identically-sized system costs comparatively less per amount of usable power.
Colder temps in Spokane reduce panel efficiency too – so wattage specs can‘t be compared equally across regions.
Solar Array Size
The average WA home requires 5-6 kW solar capacity to offset typical usage – but your needs may be above or below average. Correct sizing is critical to saving money!
Bigger homes, additional electric appliances/vehicles and other factors increase energy load. Make sure your installer evaluates consumption history before recommending a system size.
Oversizing simply costs you more upfront without improving bill savings. But too small a system can‘t power your home sufficiently.
Equipment Choices
| Panel Type | Description | Price Per Watt | Warranty |
|---|---|---|---|
| Monocrystalline | Highest efficiency rating with sleek black appearance | $3.05 | 25 years |
| Polycrystalline | Slightly lower output per panel but more affordable option | $2.58 | 25 years |
| Thin-Film | Lower performance but uniquely flexible shape options | $2.37 | 20 years |
Monocrystalline reigns supreme long-term because greater efficiency equates to more bill savings over operating lifetime – but pricier initially.
I suggest polycrystalline or thin-film only if roof space limits total number of panels.
Professional Installation Pricing
I always recommend paying market rate for a certified solar contractor over trying to DIY or use Uncle Bobs Contracting "expertise". Pay a bit more upfront and reap rewards later:
- $50K+ lifetime equipment protected only by a legit installation
- Code compliance and permitting handled
- System tuned to optimize ROI
- Workmanship warranty support if issues arise
Many fly-by-night contractors even exploitation lower component prices by installing used panels or inverters prone to early failure.
Determining Your Solar Panel Payback Period
"How many years until solar pays me back?" – I hear this constantly from curious citizens like you!
The answer varies depending on your power usage, installation cost and WA location. But on average expect a range of:
10-15 Years Payback Timeframe
Meaning it takes about a decade before cumulative energy savings surpass your initial solar investment. Here‘s a scenario:
- 6 kW Solar Array Costs: $14,000 (after incentives)
- Annual Utility Savings: $1,350
- Breakeven Year: 10
So after expenses are offset in Year 10, you bank pure profit from the sun for another 10-15 years typically.
And pro-tip: Payback happens faster stacking incentives like federal tax credits on top of super low interest solar loans. Ask your installer to maximize your savings!
Available WA Solar Incentives – Collect ‘Em All!
Don‘t leave free money on the table when going solar. State incentives coupled with federal tax breaks can lop 30% or more off your project cost!
I‘ve compiled the full gamut of solar incentives, rebates, tax exemptions and credits Washington makes available:
State Support
- Sales & Use Tax Exemption – Saves 8-10% costs on equipment
- Net Metering – Utility repurchases your solar electricity
- Green Power Incentives – Extra savings from utility rewards programs
Federal Help
- Investment Tax Credit (ITC) – 30% back on entire system cost
Local Love
- County Grants – Check if your municipality offers solar cash
- Special Green Energy Rates – Some utilities give solar customers discounted pricing
And while outlays have expired for now, keep an eye out for SREC trading subsidies reopening.
Top Solar Installers to Call for Quotes
Okay okay I realize your brain might melt trying to model the minutiae on solar costs/savings.
Let me put this project on autopilot:
I recommend getting proposals from multiple NABCEP certified solar pros before moving forward.
Having personally installed over 5 megawatts of solar across Washington, I feel extremely confident recommending these fine local companies:
- Sunergy Solar
- Solarc Energy Group
- Intermountain Wind & Solar
- Artisan Electric
- Sunlight Solar Energy
Each brings years of Pacific Northwest renewable energy experience to the table. They‘ll assess your home‘s unique needs, model financials and transparently explain how incentives improve payback timeline.
No pressure or obligation to buy – but rather think of it as getting educated from regional solar veterans.
So what do you say? Ready to crunch the numbers on harvesting free, renewable energy? Let‘s chat!
