Why solar still wins in California
Electricity here is among the most expensive in the country, and rates keep climbing. A solar-plus-battery system lets you generate and store your own power instead of buying it at peak rates — most homeowners see payback in roughly 7–9 years.
- Hedge against utility rate increases
- No property-tax increase on the added value (CA exclusion)
- Clean power you own and control
What's included with every install
A custom Aurora-modeled design, a written production estimate, 24/7 monitoring, our workmanship warranty, and manufacturer warranties that stay valid no matter what — all coordinated by one accountable local team from design to power-on.
- Custom engineered design + written production estimate
- In-house permitting, interconnection & PTO
- 24/7 monitoring + workmanship warranty

Good questions
Residential Solar FAQ
It depends on your annual usage, roof, and whether you add a battery — most California single-family homes land in the 8–10 kW range. We model your real usage and roof in Aurora, and your proposal shows the exact panel count, layout, and a written production estimate. Under NEM 3.0 the right size covers your usage and charges a battery, rather than maximizing panel count.
