What matters in Hayward
Key takeaways
- Utility: PG&E.
- Marine layer and roof shade make site-specific modeling important.
- PG&E interconnection is separate from city permit approval.
For Hayward, this guide uses 3 official utility, permitting, or licensing sources plus 2 installer-owned service-area sources; re-check each before contracting.
Hayward's dense East Bay housing, mixed roof ages, and variable coastal-inland exposure make roof condition and shade analysis central to comparing proposals.
Climate and property considerations
Marine layer, coastal humidity, occasional wind, and roof shade can reduce output relative to clear-sky estimates. Inspect roof moisture, corrosion exposure, and shading carefully.
Interconnection
PG&E's current Solar Billing Plan and Rule 21 interconnection process apply. PG&E must approve the interconnection and issue Permission to Operate; export terms depend on the applicable tariff.
Dated official sources
These primary sources are tied to the local claims above. Re-check them before signing because rules and program terms change.
