The clearest way to go solar in San Diego
Three very different experiences hide behind the same word "solar." Here is how a local, own-your-system installer stacks up against a national brand and a door-to-door lease.
| What matters | San Diego Solar Surfers | National installer | Door-to-door lease / PPA |
|---|---|---|---|
| Who does the work | Local San Diego crew, on your roof since 2013 | Regional subcontractors routed through a call center | Commissioned salesperson; install crew varies |
| You own the system | Yes, you own it and keep every incentive | Usually purchase or loan | No, the company keeps the panels and the tax credit |
| Pricing | Transparent line-item quote, no pressure | National pricing, add-ons at signing | Escalator clauses that raise your rate over time |
| Warranty and service | 25-year equipment warranty, local team answers | Manufacturer warranty, service tickets queued | Tied to a lease contract, not to your home |
| Financing options | $0-down financing, cash, and 30% federal ITC | In-house loan partner | Lease or PPA only, incentives go to them |
| Timeline and control | We handle design, permits, and SDG&E interconnection | Multi-step handoffs between departments | Fast signature, slower follow-through |
The Sunshine Promise
We design your system to a modeled first-year production target and put that estimate in writing before install. If your panels underperform that estimate, our local team comes back, diagnoses it, and makes it right at no charge. That is the Sunshine Promise.
