Consider Calpro Solar if...

- ✓ Your roof is older or has complexities that would benefit from a contractor who has diagnosed and resolved decades of installation challenges
- ✓ Post-installation service responsiveness is a priority, as Calpro Solar receives specific mentions for timely assistance with system issues
- ✓ You value working with a company whose entire operational focus has been solar energy systems rather than solar as one service among many
Consider Got Watts? if...
- ✓ You're planning solar alongside other electrical upgrades like panel replacement, EV charger installation, or HVAC system work that Got Watts can coordinate in a single project
- ✓ You want multiple system design options presented with transparent pricing comparisons before making a decision
- ✓ Your project includes battery backup integration with broader home electrical considerations like manual transfer switches or whole-house power management
- ✓ You anticipate future electrical projects and prefer establishing a relationship with a contractor who can handle diverse home system needs beyond solar
Questions to Ask Before Hiring
- → Ask Calpro Solar whether they coordinate electrical panel upgrades if your current panel is insufficient for solar, or if you'd need to hire a separate electrician
- → Ask Got Watts how many solar installations they've completed in the past two years and what percentage of their business solar represents
- → Ask both companies about their warranty service process and typical response time for post-installation system issues
- → If you're considering future EV charger or battery additions, ask each company how they approach phased installations versus integrated design
The Bottom Line
If your project is solar-focused and you value maximum industry experience with a specialist who has navigated 37 years of technology and regulatory changes, Calpro Solar is the stronger choice. Their dedicated solar focus and track record for responsive post-installation service make them particularly suitable for complex installations or homeowners who prioritize depth of expertise. Choose Got Watts if you're planning solar alongside electrical panel upgrades, EV chargers, or HVAC work that benefits from coordinated project management, or if you want a contractor relationship that can handle diverse home system needs beyond solar. Both companies meet protection requirements and deliver professional service, so your decision should center on whether you need a solar specialist or an electrical generalist who does solar well.

Frequently Asked Questions
Yes, for certain situations. Calpro Solar's 37 years means they've encountered and solved more edge cases involving roof complications, utility interconnection problems, and permit issues specific to older Contra Costa County homes. If your project is straightforward on a newer home, Got Watts' 12 years provides sufficient expertise. For complex roofs, older electrical systems, or properties with unusual site conditions, Calpro Solar's deeper experience base becomes more valuable.
Yes, Got Watts installs solar systems regularly and receives positive feedback specifically for solar projects. The advantage of their broader expertise appears when your home needs electrical panel upgrades to support solar, or when you want to coordinate solar with EV charger installation or HVAC work. For standalone solar installations, their detailed proposal process and professional installation crews perform the work competently.

Calpro Solar's feedback specifically mentions responsive service for system additions and issues, suggesting they maintain ongoing customer relationships well.

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.
