PSE Solar: The Real Picture
Puget Sound Energy serves approximately 1.2 million electric customers across western Washington, from the Seattle suburbs through Bellingham, Olympia, and beyond. PSE offers net metering for residential solar, and Washington's commitment to 100% clean electricity by 2045 ensures continued policy support.
Customers: ~1.2 million electric accounts
Average rate: $0.10-$0.12/kWh (among lowest in US)
Net metering: Full retail rate up to 100 kW
Solar production: ~1,000-1,100 kWh/kW annually (Source: NREL PVWatts)
The honest truth: PSE territory has two factors working against solar economics: low electricity rates (thanks to abundant hydropower) and lower solar production (thanks to the marine climate). This doesn't mean solar is a bad idea, but it does mean you need different expectations than someone in Arizona or California.
PSE Net Metering Program
The good news: PSE's net metering program is solid. You get full retail credit for excess solar production, which is better than many utilities offer.
How PSE Net Metering Works
| Feature | PSE Policy |
|---|---|
| Credit rate | Full retail rate (kWh-for-kWh) |
| System size limit | Up to 100 kW residential |
| Credit rollover | Monthly credits carry forward |
| Annual true-up date | March 31 |
| Excess at true-up | Paid at avoided cost (much lower) |
| Meter type | Bi-directional (no cost from PSE) |
Important Net Metering Details
- Size your system right: Credits above your annual usage are paid at avoided cost (wholesale rate, around $0.02-$0.04/kWh). Oversizing wastes money.
- True-up timing: March 31 true-up means credits from summer production carry through winter when you produce less.
- No minimum bill: PSE does not currently charge a minimum bill or solar-specific fee beyond standard connection charges.
PSE Rate Structures
PSE uses a tiered rate structure for residential customers. Understanding this helps you estimate solar savings accurately.
PSE Residential Electric Rates (2026)
| Tier | Usage | Rate (approx.) |
|---|---|---|
| Tier 1 | First 600 kWh/month | ~$0.095/kWh |
| Tier 2 | Above 600 kWh/month | ~$0.11/kWh |
| Basic charge | Monthly | ~$8.50/month |
Why PSE Rates Matter for Solar
Lower electricity rates mean lower savings per kWh of solar production:
| Utility/Region | Average Rate | Solar Value per 1,000 kWh |
|---|---|---|
| PG&E (California) | $0.35-$0.45/kWh | $350-$450 |
| Con Edison (NY) | $0.25-$0.30/kWh | $250-$300 |
| National Average | $0.16-$0.18/kWh | $160-$180 |
| PSE (Washington) | $0.10-$0.12/kWh | $100-$120 |
This is the core challenge: Every kWh your solar produces saves you only $0.10-$0.12 with PSE, while a California homeowner saves $0.35-$0.45 for the same kWh. Same panels, same sun (actually more sun in CA), 3-4x less value per kWh.
Solar Production Reality in Western Washington
Let's address the elephant in the room: the Pacific Northwest is cloudy. Here's what that actually means for solar production.
Annual Solar Production by Location
| Location | kWh per kW/year | vs. Phoenix |
|---|---|---|
| Phoenix, AZ | 1,700-1,800 | 100% |
| Los Angeles, CA | 1,550-1,650 | ~92% |
| Denver, CO | 1,450-1,550 | ~86% |
| New York, NY | 1,200-1,300 | ~72% |
| Seattle area (PSE) | 1,000-1,100 | ~62% |
Seasonal Variation in PSE Territory
The Pacific Northwest has extreme seasonal variation. This is actually good news and bad news:
| Month | % of Annual Production | Notes |
|---|---|---|
| June | ~14-15% | Best month! 15+ hours daylight |
| July | ~13-14% | Long, often sunny days |
| May/August | ~11-12% each | Strong production |
| April/September | ~8-9% each | Decent shoulder months |
| March/October | ~5-6% each | Variable weather |
| November-February | ~2-4% each | Dark, cloudy, challenging |
Factors That Affect Your Specific Production
- Roof orientation: South-facing is ideal; west-facing loses ~10-15%
- Roof pitch: 30-40 degree tilt optimal for Seattle latitude
- Shading: Trees are common; shade analysis is critical
- Local microclimate: Some areas sunnier than others
- Panel quality: High-efficiency panels help in low-light conditions
Realistic Savings for PSE Customers
Here's what PSE customers can realistically expect from solar in 2026. No hype, just math.
Example: Average PSE Home
Assumptions: 900 kWh/month usage, 8 kW system, south-facing roof
| Metric | Cash Purchase | Solar Loan | PPA/Lease |
|---|---|---|---|
| System cost | $24,000-$28,000 | $24,000-$28,000 | $0 down |
| Federal tax credit | None (25D expired) | None (25D expired) | 30% (to company) |
| Net cost | $24,000-$28,000 | $28,000-$34,000* | $0 |
| Annual production | ~8,400 kWh | ~8,400 kWh | ~8,400 kWh |
| Annual savings | $840-$1,000 | $100-$300** | $150-$300 |
| Payback period | 12-16 years | N/A (loan) | Immediate |
| 25-year savings | $25,000-$35,000 | $15,000-$22,000 | $10,000-$18,000 |
*Includes loan interest at 6-8% over 10-15 years
**Net savings = utility savings minus loan payment
Payback Comparison by Region
| Utility/Region | Typical Payback | Why |
|---|---|---|
| PG&E (California) | 6-9 years | High rates, good sun |
| Con Edison (New York) | 7-10 years | High rates, state incentives |
| Duke Energy (Southeast) | 10-14 years | Moderate rates, good sun |
| PSE (Washington) | 12-16 years | Low rates, less sun |
Best Strategy for PSE Customers
Who Should Go Solar with PSE
- Long-term homeowners: Planning to stay 15+ years to capture full value
- Environmental priority: Clean energy matters beyond just ROI
- Rate lock mindset: Want to lock in electricity cost for 25+ years
- High electricity users: Bills over $150/month see better returns
- Good roof situation: South-facing, minimal shading, newer roof
Who Should Wait or Skip Solar
- Moving soon: Need 10+ years to see meaningful ROI
- Low electricity bills: Under $80/month makes solar economics worse
- Heavy shading: Trees common in PNW; production drops significantly
- Purely financial: Better ROI available in index funds
- Older roof: Need roof replacement? Do that first
Optimal System Design for PSE
- System size: Match to 90-100% of annual usage (no oversizing)
- Panel choice: Higher efficiency helps in low-light conditions (consider 400W+ panels)
- Inverter: String inverter is fine if no shading; microinverters if any shade concerns
- Battery: Skip it unless you have specific backup needs (limited financial benefit)
- Monitoring: Real-time monitoring to ensure system performs as expected
About Batteries in PSE Territory
Unlike California, batteries generally don't make financial sense with PSE:
- No TOU rates: PSE uses tiered, not time-of-use rates (no peak/off-peak arbitrage)
- Full net metering: Grid acts as free "battery"
- Reliable power: PSE has relatively few outages compared to fire-prone areas
- Cost vs. benefit: $12,000-$15,000 battery adds maybe $50-$100/year in savings
Exception: If you experience frequent outages or have critical backup needs (medical equipment, home office), a battery provides peace of mind even if the ROI is poor.
Federal Tax Credit in 2026
| Purchase Type | Federal Credit | Notes |
|---|---|---|
| Cash/Loan purchase | None | 25D expired Dec 31, 2025 |
| PPA/Lease | 30% (to company) | 48E valid through 2027 |
Important: The elimination of the 25D tax credit makes PPAs/leases relatively more attractive in 2026 compared to purchase, especially in markets with longer paybacks like PSE territory.
Frequently Asked Questions
Is solar worth it with PSE in 2026?
It depends on your goals. Financial ROI is slower (12-16 year payback) due to low rates and cloudy weather. But solar provides a 25+ year hedge against rate increases, reduces carbon footprint, and increases home value. If pure financial return is your only goal, PSE territory is challenging. If you value energy independence, environmental impact, or rate certainty, solar can make sense.
How does PSE's annual true-up work?
Credits accumulate monthly. On March 31 each year, PSE calculates your net position. If you have excess credits (produced more than you used over the year), they're paid at avoided cost (roughly $0.02-$0.04/kWh, not retail). This is why right-sizing is critical. You want to end the year near zero credits, not with a big surplus.
Should I get a battery with PSE?
Generally no, for financial reasons. PSE has tiered rates (not TOU), so there's no peak/off-peak arbitrage opportunity. Net metering lets the grid store your excess. A battery costs $12,000-$15,000 and might save $50-$100/year in PSE territory. Only consider a battery if backup power during outages is important to you.
What happens to my solar if I move?
Solar typically adds to home value. Studies show homes with solar sell for 3-4% more, though this varies by market. In the Seattle area, where environmental values are strong, solar can be a selling point. If you have a solar loan, you'll need to pay it off at sale. PPAs/leases may require transfer to the new owner or buyout.
Can PSE disconnect me from the grid?
No, but staying connected has benefits. Net metering requires grid connection. You could theoretically go off-grid with a large battery system, but this would cost $50,000-$100,000+ and eliminate the convenience of grid backup. Staying connected is almost always the better choice.
What if I also want an EV?
EVs significantly increase electricity usage (3,000-5,000+ kWh/year for typical driving). This actually improves solar economics because you're offsetting more electricity and often hitting Tier 2 rates. If you're considering an EV, size your solar system to cover both home and EV charging.
