OnPoint Solar Panel Cleaning Encinitas

Questions worth asking

When evaluating any contractor installing solar in Cardiff, California, the questions below are the high-leverage ones to ask — they surface the things that actually affect your 25-year economics and protect against the failure modes specific to California's permitting and net metering rules.

1. 1. What contractor license do you hold for solar installs in California, and can you share the license number?

   We sourced this listing from public business data; we have not independently verified OnPoint Solar Panel Cleaning Encinitas's license status. The license check is the single most important pre-contract step.

2. 2. How do you size residential systems against my annual usage versus my peak monthly demand?

   Sizing should be based on your historical bills (annual kWh) plus any expected changes (EV, heat pump, etc.). A vague answer here is a yellow flag.

3. 3. What panel and inverter brands do you currently install, and why those?

   Installers tend to favor 1–3 brands they're trained on. The answer tells you what you're signing up for in 25-year warranty terms.

4. 4. What's your typical response time when a customer calls with a service request after the install is complete?

   This separates installers who treat solar as a one-shot sale from those who run a real service operation.

5. 5. What's your workmanship warranty term, and is it transferable if I sell my home?

   Strong installers offer 10+ year workmanship warranties that transfer with the property. This is what protects you against roof leaks and structural attachment failures.

6. 6. Can you provide three references from completed residential projects in the past 12 months?

   Recent references matter more than aggregate review counts; the installation team and standards can change quickly in solar.
