Sun Light & Power
I'm on my fourth project with SL&P and I have to say that they are one of the very best contracting companies I have worked with. They are very thorough and attentive to detail. The workmanship has b...
Here are my criteria for choosing a solar vendor: Long-lived company: ✅ Competitive pricing: ✅ (similar to another bid we got, and in line with local data) Good communication: ✅ (no BS, ever ...
This team is very thorough and detail oriented - as you want when having something installed on your house that is supposed to function for over 25 years. They have been around a long time and will be...
Consider Photovoltaics California if...
- ✓ Your project budget is extremely tight and Photovoltaics California offers a significantly lower bid that still meets your basic requirements.
- ✓ You have an existing relationship with this company from a previous successful project and trust their work.
- ✓ You're willing to request detailed references and verify their solar installation experience directly before signing a contract.
Consider Sun Light & Power if...
- ✓ You want a contractor with deep solar expertise who has seen and solved complex installation challenges over decades.
- ✓ Long-term support matters to you, and you value working with a company that services systems they installed 20-30 years ago.
- ✓ You need repairs or upgrades to an existing solar system, especially one installed by a company no longer in business.
- ✓ Customer feedback and documented satisfaction are important factors in your decision-making process.
Questions to Ask Before Hiring
- → Ask Photovoltaics California for references from at least three recent solar installations similar to yours, including contact information you can verify.
- → Ask Photovoltaics California how many solar installations they complete annually and how long their installation crew has been working together.
- → Ask both companies about their warranty terms and what happens if they go out of business before your system needs service.
- → Ask about their experience with your specific roof type and any complications they've encountered on similar projects.
The Bottom Line
Sun Light & Power is the clear choice for most homeowners. Their 49 years of solar specialization, documented customer satisfaction, proven ability to service decades-old systems, and employee-owned commitment to quality provide substantially more protection for your solar investment than Photovoltaics California can demonstrate. Solar panels should function for 25-30 years, and you need a contractor with the expertise to install them correctly and the longevity to support them long-term. Photovoltaics California might be worth considering only if they offer a significantly lower price and you thoroughly verify their solar experience through multiple recent references.

Frequently Asked Questions
Yes, significantly. Solar technology has evolved through multiple generations, and a company with 49 years has handled thousands of installations across every roof type, structural challenge, and system configuration. They've diagnosed problems that newer companies haven't encountered, know how components fail over time, and understand how to future-proof installations. When issues arise 10-15 years from now, experience depth makes the difference between quick resolution and costly troubleshooting.
This is unclear from available data and represents a legitimate concern. After 11 years in business, an active solar contractor should have accumulated customer reviews unless they complete very few projects or don't actively solicit feedback. Before hiring them, ask directly about their annual project volume and request verifiable references from recent solar installations you can contact independently.
Yes, this is specifically mentioned as one of their services. They handle inverter replacements, system upgrades, troubleshooting, and repairs for systems originally installed by other companies, including those no longer in business. With 49 years of experience, they've likely encountered most system types and manufacturers, making them well-equipped to diagnose and resolve issues.
Customer feedback suggests it contributes to a culture where crew members act as company ambassadors rather than just completing assigned tasks. This appears to translate into better communication, accountability, and attention to detail. While ownership structure alone doesn't guarantee quality, the combination of employee ownership and documented customer satisfaction indicates a workplace that prioritizes long-term reputation over short-term profits.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
