What’s specific about solar in Grossmont

- 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.

Grossmont solar FAQ
Can I install solar on a Grossmont-area condo?
Yes, but condo solar requires both the building’s HOA approval and the city permit. We work with the condo board to provide architectural drawings and confirm that the roof area corresponding to your unit is part of your exclusive-use easement. The process adds 30 to 60 days to a typical install timeline.
How long does a solar installation take in Grossmont?
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 Grossmont homes need?
Most Grossmont 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.
