Solar Panel Installation in Glendale, CA
Glendale Water & Power runs its own net metering program and its own interconnection review, both of which behave differently from SCE. We have been through that queue plenty of times.
We are based in Northridge, 15 miles away, and we design Glendale systems around Glendale Water & Power’s actual rate structure rather than a national average. Permits go through City of Glendale Building & Safety. Roofs here are typically spanish tile and composition shingle, which determines the mounting hardware we quote.

GWP in plain language
Municipal rates are lower than SCE's, so payback leans on system size and self-consumption rather than export arbitrage. Glendale runs its own interconnection review.

That narrow gap is why solar alone still performs well in Glendale. A battery here earns its keep through outage protection rather than rate arbitrage, and we will tell you honestly which one you are buying.

A different calculation. GWP is a municipal utility, so it sets its own rules and still credits exports near retail — about $0.20 per kilowatt-hour. Solar alone performs well here. A battery is worth buying for outage protection rather than for rate arbitrage, and GWP customers are not eligible for SGIP.
Show the assumptions
Usage derived from $320/mo at GWP’s ~$0.23/kWh blended rate, giving 16,696 kWh a year.
Production at 5.6 peak sun hours a day with a 0.80 derate for inverter, wiring, soiling and heat losses: 16,548 kWh a year.
Self-consumption assumed at 88% of production; the remainder is exported at $0.20/kWh.
25-year figure compounds utility rates at 4.5% a year and degrades panel output 0.5% a year, net of system cost. Planning estimate only, not a quote.

Glendale questions
Answered with local numbers
Specific to Glendale, GWP, and City of Glendale Building & Safety.
How much does solar cost in Glendale?
A typical Glendale home paying around $300 a month to GWP needs roughly a 9.7 kW system, which lands near $30,976 installed before storage. Adding the 13.5 kWh battery we would normally pair with it brings the project to about $46,501. Roof type matters here: spanish tile and composition shingle is what we mostly see in Glendale, and that affects mounting hardware and labor.
Is solar worth it in Glendale with GWP?
Municipal rates are lower than SCE's, so payback leans on system size and self-consumption rather than export arbitrage. Glendale runs its own interconnection review. At 5.6 peak sun hours a day, a 9.7 kW array in Glendale produces roughly 15,829 kWh a year. Against GWP's approximate $0.23 per kWh, that is around $3,584 of annual value, putting simple payback near 13.0 years.
Who issues solar permits in Glendale?
Permits for Glendale go through City of Glendale Building & Safety, and interconnection is handled separately by Glendale Water & Power. Those are two different clocks and they do not run in parallel by default. We file both and chase the corrections, which is usually where projects stall when homeowners manage it themselves.
Do you install batteries in Glendale?
Yes. Note that Glendale is served by Glendale Water & Power, a municipal utility, so SGIP rebates are not available — that program is funded by investor-owned utility ratepayers. GWP still credits exports near retail at roughly $0.20 per kWh, so in Glendale a battery is primarily about outage protection rather than rate arbitrage.
How far is Glendale from your Northridge shop?
About 15 miles. That is comfortably inside our core service area, so surveys and service calls are quick to schedule.
