Advanced Solar Technologies Inc
Based in San Diego, California, Advanced Solar Technologies Inc is a solar installer listed on Aora Solar's directory. They hold a state-issued contractor license (#862598) on file with the licensing board, meeting the baseline regulatory bar for residential solar work in the state.
Aora Solar's records list services across rooftop solar installation and solar with battery storage. Like most residential solar installers, the day-to-day work involves rooftop system design, AHJ permitting, utility interconnection paperwork, and the post-install commissioning that gets a homeowner from contract to permission-to-operate.
Contact information on file includes a phone, website, and mailing address (see the contact card below). Before signing a contract, we recommend asking for proof of current state license and insurance, three references from installs completed in the past 12 months, the panel and inverter brands used, and the linear-power warranty term for both. A solid solar installer will share all of these without hesitation.
This profile was assembled from public state licensing records and OpenStreetMap business data. Specific business details should be verified directly with the contractor before any project commitment.
Questions worth asking
When evaluating any contractor installing solar in San Diego, California, the questions below are the high-leverage ones to ask — they surface the things that actually affect your 25-year economics and protect against the failure modes specific to California's permitting and net metering rules.
1. Can you confirm your active license (862598) and provide a copy of your current certificate of insurance?
Advanced Solar Technologies Inc appears in California state contractor licensing records. Confirming the license is still active and asking for insurance proof should take a few minutes for any legitimate operator.
2. How do you size residential systems against my annual usage versus my peak monthly demand?
Sizing should be based on your historical bills (annual kWh) plus any expected changes (EV, heat pump, etc.). A vague answer here is a yellow flag.
3. What panel and inverter brands do you currently install, and why those?
Installers tend to favor 1–3 brands they're trained on. The answer tells you what you're signing up for in 25-year warranty terms.
4. Which battery brands do you install (Tesla Powerwall, Enphase IQ, Franklin WH, etc.), and what's the typical added cost for whole-home vs. partial-home backup?
Battery brand affects backup duration, inverter compatibility, and warranty terms. Whole-home backup typically costs 1.3–1.7× partial-home.
5. What's your typical response time when a customer calls with a service request after the install is complete?
This separates installers who treat solar as a one-shot sale from those who run a real service operation.
6. What's your workmanship warranty term, and is it transferable if I sell my home?
Strong installers offer 10+ year workmanship warranties that transfer with the property. This is what protects you against roof leaks and structural attachment failures.
7. Can you provide three references from completed residential projects in the past 12 months?
Recent references matter more than aggregate review counts; the installation team and standards can change quickly in solar.
San Diego solar permits are issued by San Diego Development Services Department. Utility interconnection runs through San Diego Gas & Electric (SDG&E). Typical permit timeline: Same-day (SolarAPP+) to 10 business days. This jurisdiction supports SolarAPP+ for same-day approval of code-compliant residential PV.
- •SolarAPP+ enabled for code-compliant residential PV.
- •Coastal Zone reviews required for properties in coastal commission area.
- •Fire-area special requirements for properties in High and Very High Fire Hazard Severity Zones.
