Consider Enphase Energy if...
- ✓ You already have an Enphase system installed by another contractor and need technical support for connectivity issues, monitoring problems, or warranty claims on Enphase equipment
- ✓ Your original installer went out of business and you need help troubleshooting or replacing Enphase microinverters or batteries
- ✓ You're researching equipment options and want to understand Enphase product capabilities before selecting an installer who works with their technology
Consider Sun Light & Power if...
- ✓ You need a complete solar installation from initial assessment through final inspection and you want a contractor who will still be available for service in 10 or 20 years
- ✓ Your project involves complications like steep roofing, older homes, system upgrades, or integrating battery storage with existing arrays where decades of field experience matters
- ✓ You value working with an employee-owned company known for thorough consultations, realistic projections, and professional installation crews rather than high-pressure sales
- ✓ You need repairs or upgrades to a system originally installed by a company that's no longer in business
Questions to Ask Before Hiring
- → Ask Enphase directly whether they perform residential installations in your area or if they can recommend certified installers who use their equipment
- → Ask Sun Light & Power about their experience with the specific roof type and complexity your home presents, particularly if you have tile, steep pitch, or structural concerns
- → Ask Sun Light & Power how their employee-owned structure affects crew consistency and who will handle service calls years after installation
- → Ask both companies about equipment warranties versus workmanship warranties and who handles each type of claim
The Bottom Line
For nearly all homeowners seeking solar installation, Sun Light & Power is the appropriate choice. Their 49 years of contractor experience, professional installation crews, and track record of thorough project management make them well-suited for new installations, system upgrades, and complex repairs. Enphase Energy serves a different role as an equipment manufacturer—contact them only if you already have Enphase equipment and need technical support, or if you're researching product options before hiring an installer. If you want Enphase microinverters or batteries as part of your installation, ask Sun Light & Power whether they're a certified Enphase installer and can incorporate that equipment into your project.

Frequently Asked Questions
Enphase primarily operates as an equipment manufacturer, not an installation contractor. While they hold a California contractor license with less than one year of history, customer feedback consistently describes technical support interactions rather than installation services. If you want Enphase equipment, you'll likely need to hire a certified installer like Sun Light & Power who works with their products.
Longevity in solar contracting means Sun Light & Power has handled thousands of installations across changing technologies, building codes, and utility requirements. This translates to fewer permitting delays, better problem-solving when complications arise, and confidence they'll be available for warranty work and system service decades from now—a meaningful consideration when many solar installers fail within their first decade. Request quotes from multiple contractors to compare pricing alongside experience.
For equipment defects, connectivity issues, or warranty claims on Enphase microinverters and batteries, contact Enphase technical support directly. For physical installation problems, roof leaks, wiring issues, or system design questions, contact the contractor who installed your system. If that company is no longer in business, a full-service contractor like Sun Light & Power can diagnose and repair systems regardless of original installer.
Employee ownership typically means workers have a financial stake in the company's reputation and longevity. Customers mention this structure contributing to a culture where crew members act as company ambassadors. Practically, this may translate to more consistent quality control and accountability, though you should still verify crew qualifications and ask about specific technicians who will work on your project.

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.
