What Customers Say
Power On Solar
Power On Solar receives praise for smooth initial installations and clear system explanations but faces consistent complaints about unresponsive post-installation service and delayed repairs.
Tesla
Tesla earns positive feedback for timely installations, clear communication throughout the permitting process, and successfully handling complex roof conditions without service gaps.
Key Takeaway: The most critical contrast is post-installation support reliability, where Power On Solar shows a pattern of service responsiveness problems while Tesla's feedback contains no such concerns.

Consider Power On Solar if...
- ✓ Your project is straightforward with no roof complications and you have strong technical skills to troubleshoot your own system issues, reducing reliance on contractor support.
- ✓ You're comfortable being persistent in follow-up communications and have flexibility to wait for service responses when problems arise.
- ✓ You value Power On Solar's local Dublin presence and want to work with a smaller contractor where owner involvement is high during the initial installation phase.
Consider Tesla if...
- ✓ You want reliable post-installation support and responsiveness when system issues arise, which is critical for maximizing your solar investment over 25 years.
- ✓ Your roof presents challenges like steep pitch, flat surfaces requiring ballasted systems, or shading obstacles that benefit from Tesla's veteran experience with complex installations.
- ✓ You value consistent communication throughout the permitting and installation process based on Tesla's track record for providing regular project updates.
- ✓ You're installing solar roof products or ground-mounted systems where Tesla's broader project scope provides proven expertise.
Questions to Ask Before Hiring
- → Ask Power On Solar specifically how they handle service requests post-installation, what their typical response time is for non-producing systems, and request contact information for recent customers you can ask about their service experience.
- → Ask Tesla about their service process for system issues and whether post-installation support is handled by the same team or a separate department.
- → If your roof has unusual features like steep pitch, flat surfaces, or shading, ask both companies for references from similar installations they've completed.
- → Clarify with both contractors what monitoring systems come with installation and how you'll be notified if system production drops unexpectedly.
The Bottom Line
Tesla is the stronger choice for most homeowners installing solar in Alameda County. Their 19-year track record, consistent positive feedback for communication and timely installations, and absence of service responsiveness complaints provide substantially better protection for your long-term solar investment. Power On Solar's recurring service issues represent a real risk that could leave you without support when systems inevitably need repairs. While Power On Solar handles initial installations smoothly, solar systems operate for decades and require reliable ongoing support. Unless you have unusual circumstances that favor a smaller contractor with high owner involvement and you're prepared to be very persistent with service requests, Tesla's veteran experience and reliable service pattern justify choosing them for this significant home investment.

Frequently Asked Questions
For most homeowners, yes. While installations go smoothly, solar systems operate for 25+ years and will eventually need service for inverter issues, panel problems, or connectivity failures. Multiple customers reporting difficulty reaching Power On Solar for repairs and extended timelines suggests a pattern that puts your long-term investment at risk. A solar system that can't be serviced promptly loses you money every day it's not producing.
Yes, particularly for complex installations and long-term reliability. Twelve additional years means Tesla has navigated more utility policy changes, handled more roof types, and diagnosed a wider range of system issues. This veteran experience becomes valuable when permitting hits complications, your roof has unusual features, or systems need troubleshooting years after installation.
Pricing isn't provided in the data, so you'll need to get quotes from both. However, any price difference should be weighed against the service reliability gap. A slightly lower price with Power On Solar offers poor value if you can't get timely repairs when your system stops producing energy and your utility bills return to pre-solar levels.
You can request specific service response guarantees in writing, but the recurring pattern across multiple customers suggests a systemic issue rather than isolated incidents. When customer feedback consistently identifies the same weakness, it reflects how the company operates rather than exceptional circumstances. Ask for recent customer references specifically about their post-installation service experience.

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.
