Solar Installation in Fresno: What You Need to Know
Fresno is the largest city in the Central Valley and one of the most solar-productive locations in the entire state. With summer temperatures routinely exceeding 105°F and PG&E electricity rates among the highest in California, the financial case for solar in Fresno is straightforward: your air conditioner runs hard from May through September, your bills spike to $300–$500 per month, and a properly sized solar system eliminates most of that cost. Fresno homeowners across all 20 ZIP codes — from the older neighborhoods near downtown (93701, 93702, 93703) to the newer developments in northeast Fresno (93720, 93730) — are making the switch to solar at a rapid pace. The city's flat valley floor means most roofs have excellent south or west-facing exposure with minimal shading, and the 300+ annual sunny days ensure your system produces near its rated output year-round.
Climate
Hot semi-arid (BSk/BSh). Summers 95–110°F, 300+ sunny days/year. Minimal fog in summer. High AC load May–September.
PG&E Outage Risk
Moderate. PSPS events rare in city core but summer grid stress can cause brief outages. Battery backup valuable for medical/home-office households.
EV Adoption
High and growing. Tesla, Rivian, Ford Lightning common. Level 2 charger installs frequently bundled with solar.
Electrical Infrastructure
Mixed. Older central neighborhoods (93701–93706, 93728) often have 100A panels needing upgrade. Northeast Fresno (93720, 93730) largely 200A-ready.

Common questions from Fresno homeowners about solar installation, battery backup, electrical panel upgrades, and EV chargers.
How many solar panels does a typical Fresno home need?
Most Fresno homes (1,500–2,500 sq ft) need 18–28 panels to eliminate their PG&E bill entirely. Fresno's 300+ sunny days per year means your system produces more energy per panel than most of California — so you may need fewer panels than you'd expect. A 2,000 sq ft home with a $350/month average bill typically needs a 22–26 panel system sized to zero out annual usage.
What ZIP codes in Fresno do you serve?
We serve all Fresno ZIP codes including 93701, 93702, 93703, 93704, 93705, 93706, 93710, 93711, 93720, 93721, 93722, 93723, 93725, 93726, 93727, 93728, 93730, 93737, 93740, and 93741. From the older Tower District neighborhoods to the newest developments in northeast Fresno, we know every part of the city.
How long does a Fresno solar installation take?
Most residential installs in Fresno take 1–2 days on the roof. Permitting through the City of Fresno typically adds 2–4 weeks. We handle all permits and PG&E interconnection paperwork — you don't need to deal with any of it. From contract signing to system activation, most Fresno projects complete in 4–6 weeks.
Do I need a panel upgrade before going solar in Fresno?
Many Fresno homes built before 1990 — particularly in the 93701, 93702, 93703, 93704, 93705, 93706, and 93728 ZIP codes — have 100-amp panels that need upgrading to 200-amp before solar can be installed. We assess this during your free site visit and include panel upgrades in our scope when needed. Newer northeast Fresno homes (93720, 93730) are usually already 200-amp ready.
Is battery backup worth it in Fresno?
With PG&E's PSPS outages becoming more frequent and summer heat events stressing the grid, battery backup gives Fresno homeowners peace of mind. Under NEM 3.0, batteries also help you maximize the value of your solar by storing energy for evening use instead of selling it back at low export rates. For households with medical equipment, home offices, or young children, battery backup is worth serious consideration.
Can I add an EV charger to my Fresno solar installation?
Yes — and it's one of the most popular add-ons we do in Fresno. A Level 2 (240V) EV charger charges your vehicle 5–8x faster than a standard outlet. Paired with solar, you're effectively driving on sunshine. We handle the charger installation, any panel upgrade needed, and all permits in a single project.

(559) 355-1025Getting Solar Right in Fresno
Fresno's electrical infrastructure varies significantly by neighborhood. Homes in the Tower District, Fig Garden, and central Fresno ZIP codes (93704, 93705, 93728) were largely built in the 1950s–1970s and frequently have 100-amp service panels that must be upgraded to 200-amp before solar or EV charger installation. Newer developments in northeast Fresno (93720, 93730) and southeast Fresno (93725, 93727) are more likely to already have 200-amp service and may even have solar conduit pre-runs. EV adoption in Fresno has grown sharply — Tesla, Rivian, and Ford F-150 Lightning ownership is rising across all ZIP codes, and Level 2 charger installation is increasingly bundled with solar projects. PG&E PSPS outages affect Fresno less frequently than foothill communities, but summer heat events and grid stress can cause rolling outages — battery backup is worth considering for households with medical equipment or home offices. Robbins Energy has completed over 850 installs across Fresno County and knows every neighborhood's permit timeline, roof type, and utility interconnection quirks.
