Consider TSP Roofing and Solar if...
- ✓ Your project involves both roof work and solar installation, and you want one contractor coordinating both scopes rather than managing separate roofing and electrical companies
- ✓ You need quick turnaround on a straightforward residential solar installation or roof repair, and reviews suggest TSP completes certain projects in as little as one day
- ✓ You're working with an existing solar system that needs troubleshooting or component replacement like inverters, and TSP has experience with repair calls
- ✓ You prefer high owner involvement and frequent project updates including progress photos throughout the work
Consider Got Watts? if...
- ✓ Your project is purely electrical (solar, battery backup, EV charger, panel upgrade, HVAC electrical) without any roofing component, making Got Watts' specialized electrical focus more relevant
- ✓ You want a contractor with over a decade of experience handling permit coordination, utility interconnections, and code compliance for complex electrical installations
- ✓ You're planning a phased approach (solar now, battery later, EV charger next year) and want an established company likely to be available for future additions
- ✓ You value detailed system design options and transparent pricing comparisons before committing to a specific configuration
Questions to Ask Before Hiring
- → Ask TSP for references from solar projects completed in the past year similar to yours in system size and electrical complexity, particularly if panel upgrades or service changes are involved
- → Ask Got Watts whether they coordinate directly with roofing contractors if your project requires any roof penetrations, flashing work, or structural evaluation before solar installation
- → Ask both companies how they handle warranty service calls and what their response time is for system issues that arise after installation
- → Confirm with both contractors what specifically is covered under their $25,000 bond and how permit failures or utility approval delays would be handled
The Bottom Line
If your project combines roofing and solar work, TSP Roofing and Solar offers the convenience of single-contractor coordination, responsive communication, and fast execution. Their 3 years of experience is adequate for straightforward residential installations when roof and solar scopes overlap. If your project is purely electrical—solar, batteries, EV chargers, or panel upgrades without roofing involvement—Got Watts' 12 years of electrical specialization provides significantly deeper experience navigating complex electrical scenarios, permit processes, and utility requirements. For most solar-only projects on homes with adequate electrical infrastructure, Got Watts' established track record offers more confidence in handling complications that may arise.

Frequently Asked Questions
Not necessarily less reliable for standard residential installations, but it does mean fewer years navigating complex electrical situations, utility requirements, and code changes. For straightforward rooftop solar on a home with adequate electrical service, TSP's 3 years may be sufficient. For projects requiring significant electrical upgrades, service panel replacements, or complex battery integration, Got Watts' 12 years of electrical-specific experience offers more depth in troubleshooting and compliance.
It matters in terms of specialization depth. TSP approaches solar as an addition to their roofing business, while Got Watts approaches it as core electrical work. Got Watts likely has more experience with complex electrical scenarios like main panel upgrades, load calculations, and utility interconnection requirements. If your solar project requires no electrical service changes and your roof is in good condition, TSP's combined expertise may still serve you well, particularly if speed is a priority.
Got Watts has explicit experience with battery backup systems as a standalone electrical project, and their customer feedback mentions returning for battery additions after initial solar installs. TSP does handle solar battery installations, but their review data focuses more on combined new installations rather than retrofitting batteries to existing systems. Ask both contractors about their specific experience integrating batteries with your current system's inverter and electrical setup.
Got Watts is an electrical contractor, not a roofer. If your solar installation requires roof repairs, flashing replacement, or structural evaluation, you'd need to coordinate that separately or ask if Got Watts has a roofing partner they work with regularly. TSP handles both directly, which simplifies coordination and provides single-point accountability if roof penetrations or related issues arise later.

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.
