What Customers Say
Power On Solar
Power On Solar performs initial installations smoothly with clear explanations, but multiple customers report significant difficulty reaching the company for post-installation service and experience extended repair timelines.
Tesla
Tesla consistently delivers timely installations with regular communication updates, clear system explanations, and successfully handles challenging roof conditions without post-installation service complaints.
Key Takeaway: The critical contrast is post-installation support reliability—Tesla's feedback contains no service responsiveness concerns while Power On Solar faces a recurring pattern of customers unable to reach the company for repairs and system issues.

Consider Power On Solar if...
- ✓ Your solar project is straightforward with no challenging roof features and you're working with a very tight budget that requires the lowest possible bid, though be aware this comes with documented service risk.
- ✓ You specifically prefer working with a smaller Dublin-based company and are prepared to be persistent about follow-up if service issues arise.
- ✓ You have the time and inclination to manage post-installation service coordination yourself and don't expect the contractor to be your primary support resource.
Consider Tesla if...
- ✓ Your roof has challenging features like steep pitches, flat sections requiring ballasted systems, or obstacles like vent pipes that require experienced problem-solving.
- ✓ Post-installation support matters to you, as you want confidence that service calls will be answered and issues resolved without extended delays over the system's 25-year lifespan.
- ✓ You value a contractor with nearly two decades of experience navigating permitting, utility coordination, and inspection processes with demonstrated ability to meet installation timelines.
- ✓ Clear, regular communication during the project matters to you, particularly during the permitting phase which can involve waiting periods.
Questions to Ask Before Hiring
- → Ask Power On Solar specifically how they've addressed the service responsiveness concerns mentioned in customer feedback and what their current average response time is for system issues.
- → Ask Tesla about their service model for post-installation support, including typical response times and whether you'll have a dedicated service contact.
- → Ask both companies for references from installations completed 3-5 years ago so you can speak with customers about their long-term service experience, not just installation quality.
- → Ask about warranty coverage specifics and who handles warranty claims—the contractor or the equipment manufacturer directly.
The Bottom Line
Tesla is the clear choice for most homeowners. With 19 years of licensing experience versus 7, they bring substantially more expertise in handling complex roof conditions and navigating the permitting process. More importantly, their customer feedback shows reliable communication and timely installations without the post-installation service problems that plague Power On Solar. Since you're making a 25-year investment that will require occasional service, choosing a contractor with proven longevity and no service responsiveness concerns is essential. Consider Power On Solar only if you receive a significantly lower bid and are prepared to manage service issues persistently yourself. Get quotes from both, but unless Power On Solar offers a compelling price difference and can specifically address their service track record, Tesla's veteran experience and demonstrated reliability make them the safer choice.

Frequently Asked Questions
Yes, particularly for challenging situations. Tesla's 19 years means they've handled thousands more installations across diverse roof types, dealt with more permitting complications, and solved problems you won't anticipate until they arise. More critically, their longevity suggests they'll likely still be in business when you need service in year 10 or 15 of your system's life. Power On Solar's 7 years is adequate for straightforward installations, but the service responsiveness issues in their feedback suggest they may lack the infrastructure to support their growing customer base long-term.
It's a documented pattern, not an isolated complaint. Multiple customers specifically mention difficulty reaching the company for system issues, non-responsive panels, and extended repair timelines. For a solar system that's a 25-year investment requiring occasional service, this is a serious concern. If you choose Power On Solar, you should have a clear conversation upfront about their service protocols and get written commitments about response times.
Not based on the customer feedback. Tesla's reviews specifically mention courteous crews, clear explanations, and regular project updates—indicating they haven't sacrificed customer service despite their scale. Their size actually appears to be an advantage, providing the infrastructure for reliable post-installation support that Power On Solar struggles to deliver. Both companies are local to Alameda County, so you're not sacrificing regional presence.
The data doesn't include pricing information, which can vary significantly based on system size, equipment choices, and roof complexity. Get detailed quotes from both, but remember that the lowest bid matters less if you can't get service calls returned. Factor the value of reliable long-term support and nearly two decades of problem-solving experience when comparing prices.

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.
