Frequently asked questions
How much does residential solar cost in Ventura County in 2026?+
A typical 6.4 kW system costs $19,200–$28,800 installed, or $13,440–$20,160 after the 30% federal tax credit. Pricing varies with roof complexity, panel choice, and whether your service panel needs upgrading ($2,500–$4,500 for 100A → 200A).
What size solar system do I need?+
Most Ventura County families need 5–8 kW. We size based on your last 12 months of SCE bills, your roof's usable area, and whether you're adding an EV or a heat pump. We'd rather under-promise and over-deliver than oversize.
What solar panels do you install?+
Tier-one only — Qcells, REC, SunPower, and Silfab. We default to 410W–440W modules with Enphase IQ8 microinverters (panel-level monitoring and best shading tolerance). String inverters are available where they make sense.
How long is the warranty?+
25-year panel performance warranty, 25-year Enphase microinverter warranty, and a 10-year Sespe workmanship warranty backed by the installing C-10 contractor — not a national 800 number.
Will you handle permits and SCE interconnection?+
Yes. We pull the city or county building permit, file the SCE interconnection application, coordinate the inspection, and submit the final Permission to Operate (PTO) paperwork. Typical end-to-end timeline is 6–12 weeks.
What's the 30% federal solar tax credit in 2026?+
The Residential Clean Energy Credit covers 30% of total installed cost (panels, inverters, batteries, labor) through 2032 under the Inflation Reduction Act. There is no income cap and no upper dollar limit. Your tax preparer files Form 5695.
