The Lake Murray area of La Mesa surrounds the reservoir of the same name, a popular jogging and boating destination managed by the city of San Diego. Homes here are predominantly 1960s–1980s single-family, with a mix of original construction and renovated mid-century properties.

What’s specific about solar in Lake Murray
Lake Murray’s older home stock means electrical panel capacity is the most common upgrade need. Many homes still have 100A service from the original build, which doesn’t have headroom for solar plus battery plus an eventual EV charger. We typically include a 200A upgrade in Lake Murray quotes.

Solar terms used on this page
- kW (kilowatt)
- A measure of system size — the maximum instantaneous power output. A 10 kW system produces up to 10 kW at peak sun.
- kWh (kilowatt-hour)
- A measure of energy used or produced over time. Your utility bill is in kWh.
- ITC (Investment Tax Credit)
- The 30% federal solar tax credit, currently in place through 2032. Applies to panels, inverters, batteries (when installed with solar), and structurally required roof work.
- NEM 3.0
- California’s net metering structure since April 2023. Exports credited at roughly $0.05/kWh while peak imports cost $0.40+/kWh — making solar + battery the standard design.
- SGIP
- California’s Self-Generation Incentive Program — battery storage rebate ranging from $150 to $1,000 per kWh depending on tier (General Market, Equity, Equity Resilience).
- PSPS (Public Safety Power Shutoff)
- Pre-emptive grid shutoff by SDG&E or other utilities during high fire-risk weather. A solar + battery system keeps essential loads running through PSPS events.
Lake Murray solar FAQ
What does a 200-amp panel upgrade add to my Lake Murray solar quote?
A main service panel upgrade typically runs $2,500 to $5,000 depending on whether the meter pan, service drop, and grounding need replacement. It’s usually mandatory for solar + battery + EV-readiness in Lake Murray’s older homes — and is permitted simultaneously with the solar install to avoid two trips.
How long does a solar installation take in Lake Murray?
The on-roof work is typically 1 to 3 days. The full process from contract signing to receiving Permission to Operate from SDG&E is 6 to 14 weeks depending on permit office backlog and utility interconnection queue.
What size system do most Lake Murray homes need?
Most Lake Murray homes need 7 to 10 kW of solar plus 10 to 20 kWh of battery storage to hit attractive NEM 3.0 payback. We design based on your actual SDG&E usage profile and rate plan.
