Infinium Solar Roofing And Electric
We used Infinium Solar services before to install a 5KwH Solar system in our home, which worked flawlessly for many years. Now -- it was time to upgrade with 2 Franklin home batteries to take us off t...
Two years ago i chose them. The price was best and installation is good only complaint is they were slow. You need to keep pushing them to do next step. Anyway, i was satisfied overall. Recently, the ...
The micro-inverters stopped reporting data (the solar system was functioning properly, though). I called Infinium tech support. Jiel Justo answered the call. She listened to my concerns and remotely c...
Consider Core Energy if...
- ✓ You've already worked with Core Energy on a previous project and have direct experience with their work quality and communication style
- ✓ You have strong personal referrals from neighbors or colleagues who can speak to their installation practices and post-project support
- ✓ Their bid is significantly lower and you're comfortable conducting additional due diligence to compensate for limited public feedback
Consider Infinium Solar Roofing And Electric if...
- ✓ You want documented evidence of how a contractor handles complex installations involving batteries, electrical upgrades, or EV chargers alongside solar panels
- ✓ Responsive communication and post-installation support are priorities, as customer feedback consistently mentions these strengths
- ✓ You value transparency about a contractor's customer relationships and want to understand their project management approach before signing
- ✓ Your project involves coordinating permits and utility interconnection, areas where customers specifically praise Infinium's capabilities
Questions to Ask Before Hiring
- → Ask Core Energy for at least three recent customer references you can contact directly, specifically for projects similar in scope to yours
- → Ask Core Energy how they handle post-installation issues and what their typical response time is for service calls
- → Ask both companies about their experience with your specific equipment preferences (battery brand, inverter type, panel manufacturer) and request examples of similar installations
- → Ask about crew consistency: will the same team handle your installation from start to finish, and how long have they been with the company
The Bottom Line
Infinium Solar Roofing And Electric is the clearer choice for most homeowners based on documented customer feedback, demonstrated capabilities across solar-plus-storage projects, and transparency about their work history. Their customers consistently highlight responsive communication, technical expertise, and post-installation support—critical factors for a 25-year investment on your roof. Core Energy may be competitive, but without customer feedback to assess their approach, you're accepting more uncertainty. If you're considering Core Energy, invest extra time obtaining detailed references and verifying their experience with your specific project type. For a decision this week, Infinium provides substantially more information to make a confident choice.

Frequently Asked Questions
Not significantly in this case. Both contractors have 7-8 years of experience, placing them in the same experienced tier and meaning both have navigated California's evolving solar regulations, utility interconnection requirements, and technology changes. The more meaningful difference is the documented customer feedback showing how Infinium handles projects, which Core Energy lacks.
It's a legitimate concern when making a major investment decision. Limited public feedback means you can't assess their communication style, how they handle complications, or their post-installation support approach. You'll need to compensate by requesting multiple direct references, asking detailed questions about their processes, and potentially checking their license history for complaints through the California Contractors State License Board.
Yes, meaningfully. Infinium has documented customer feedback specifically about battery installations (Tesla Powerwall, Franklin systems) and EV chargers, showing they handle multi-component projects routinely. Core Energy's description focuses solely on solar panel installation without mentioning these integrated systems. If your project involves multiple components, you want a contractor with demonstrated experience coordinating them.
The $25,000 bond is California's standard requirement and provides recourse through the Contractors State License Board if work is abandoned or not completed as agreed. It's baseline protection, not comprehensive project insurance. Your actual protection comes more from the contractor's workers compensation coverage (which both have), their track record, and a detailed written contract specifying scope, timeline, equipment, warranties, and payment schedule tied to completion milestones.

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.
