- → Ask Solaron about their current warranty terms and post-warranty service availability given customer mentions of service challenges
- → Ask Ilum for references from projects similar in complexity to yours, particularly if your installation involves difficult roof access or structural considerations
- → Confirm installation timelines and crew availability for your specific project type

Frequently Asked Questions
No, these companies serve different markets. Ilum specializes in rooftop photovoltaic systems that generate electricity for your home, while Solaron focuses exclusively on solar pool heating systems. If you need both types of solar, you'll need to hire two separate contractors.
Only if you need pool solar heating, which is Solaron's specialty. For rooftop PV systems that generate electricity, Ilum is your option since Solaron doesn't offer that service. The experience advantage only matters when companies compete for the same project type.
Ilum's reviews emphasize responsive communication and follow-through on permits and issue resolution. Solaron's reviews mention some customers experienced challenges with post-warranty service availability and difficulty resolving system performance issues. Ask both companies directly about their warranty coverage and what happens when issues arise after installation.
Ilum receives consistent feedback about fast installation timelines, with customers specifically noting quicker completion compared to other solar companies. Solaron's reviews describe efficient installations and clean worksites but don't emphasize speed as prominently. Timeline expectations will differ significantly between a rooftop PV installation and pool heating system.

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.
