Consider Cobalt Power Systems if...

- ✓ You're planning a coordinated roof replacement and solar installation simultaneously, where their established roofing contractor relationships provide seamless project management
- ✓ You value a contractor who's been through multiple solar technology generations and can advise on system longevity and future upgrade options based on actual field experience
- ✓ You're looking for a long-term relationship with a company that has demonstrated two-decade staying power for future system expansions or service needs

- ✓ You need electrical panel upgrades or EV charger installation alongside your solar project, as Infinium explicitly handles these electrical components as part of their core services
- ✓ You prioritize high owner involvement and direct access to decision-makers throughout your project timeline
- ✓ You want a contractor experienced with the latest generation of equipment like Enphase microinverters and Tesla Powerwalls who focuses on current technology rather than legacy systems
- ✓ You value responsive post-installation support and follow-up service, which customers specifically highlight in their feedback
Questions to Ask Before Hiring
- → Ask Cobalt about their current installation crew tenure and whether the same team handles both standard and specialty roofing projects
- → Ask Infinium about their experience with your specific roofing type if you have tile, slate, or other specialty materials
- → Request references from both companies for projects similar to yours in scope, including any electrical upgrades or roof coordination you're planning
- → Ask both contractors about their warranty service process and availability for future system expansions or equipment upgrades
The Bottom Line
For most straightforward solar installations, both contractors are qualified, properly insured options. Choose Cobalt Power Systems if your project involves specialty roofing materials, coordinated roof-solar work, or particularly complex scenarios where their 23 years of field experience navigating complications provides meaningful value. Their track record of multi-decade customer relationships also matters if long-term contractor availability is important to you. Choose Infinium Solar Roofing And Electric if you need electrical panel upgrades or EV charger installation as part of your solar project, or if you prioritize high owner involvement and responsive post-installation support. Either way, get detailed proposals that address your specific site conditions and verify equipment warranty support structures.

Frequently Asked Questions
For a simple installation on composition shingle roofing with no complications, the experience gap matters less. However, even straightforward projects can reveal unexpected issues like hidden roof damage or challenging electrical panel configurations, where Cobalt's 23 years of problem-solving experience provides more depth. If your project has any complexity factors, the experience difference becomes more significant.
Infinium demonstrates solid technical competence and handles battery systems, electrical upgrades, and various equipment types effectively. However, their feedback doesn't specifically mention specialty roofing materials or taking on projects others declined. If your project involves challenging roofing scenarios, ask Infinium directly about their experience with your specific situation rather than assuming capability.
Infinium explicitly lists electrical panel upgrades as a core service and receives feedback about coordinating multiple systems simultaneously. While Cobalt can likely coordinate electrical work through subcontractors, Infinium's direct electrical capabilities may streamline projects requiring significant electrical modifications. Ask both contractors how they handle the electrical scope and whether work stays in-house or requires coordination with separate electricians.
This pattern indicates two valuable things: the company remains in business and accessible for long-term service, and customers were satisfied enough to return rather than finding a different contractor. For solar systems you'll own for 20-30 years, having a contractor with demonstrated longevity provides more confidence they'll be available for future maintenance, troubleshooting, or system expansions.

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.
