Powered by sun.
Backed by battery.

Under NEM 3.0 in San Diego, the answer is almost always yes — at least for residential. Without storage, mid-day excess production gets sold back at very low rates. With a Tesla Powerwall or Enphase IQ Battery, that same production charges the battery and powers your house during peak-rate evening hours. The payback math improves dramatically.

When a solar installer goes out of business or stops returning service calls, their customers are left with a 25-year asset and no support. We service those systems — any brand, any era. Diagnostics, inverter replacement, monitoring restoration, battery retrofits, code updates. Most rescues take one to two visits.

Typical timeline from signed proposal to powered-on system is 8-12 weeks. Most of that is permitting and utility interconnection — actual roof work is one to three days. We track all the moving parts so you don't have to chase paperwork.

Residential installs typically run $3.00-$4.00 per watt before incentives. A 7 kW system is roughly $21,000-$28,000 installed, then minus the 30% federal tax credit. We model your actual rate, system size, and storage needs before quoting — no two homes are the same.

We work with several financing partners and can also discuss PPA (power purchase agreement) and lease structures, but we'll always be honest about which option pencils best for your specific situation. Cash, loan, PPA, and lease all have trade-offs.

Yes. Perk Solar is a Tesla-certified Powerwall installer. We also work across Enphase, Sigenergy / PointGuard, and EcoFlow — we recommend based on the project, not on what's stocked in the warehouse.

Yes — commercial PV, solar carports, ground-mount arrays, demand-charge management, and battery-paired systems for owner-operated businesses, multi-tenant retail, restaurants, auto shops, churches, schools, and light industrial properties across San Diego County.
