All On Electric And Solar
Quality Work. Polite and friendly staff
Consider Tesla if...
- ✓ Your property has challenging roof characteristics like steep pitch, flat sections requiring ballasted mounting, or significant obstacles like vent pipes and skylights that require experienced installation planning
- ✓ You want documented evidence of how a contractor handles the permitting and inspection process in Alameda County, where customers report Tesla provides regular updates and manages bureaucratic requirements effectively
- ✓ You value verifiable customer feedback showing consistent timeline adherence and utility bill reductions, giving you confidence in projected savings and installation schedules
- ✓ Your project involves energy storage integration alongside solar panels, where Tesla's documented experience with comprehensive systems provides execution assurance
Consider All On Electric And Solar if...
- ✓ You have existing electrical work that needs updating or modification alongside your solar installation, potentially benefiting from All On Electric And Solar's dual electrical-solar licensing
- ✓ You're in Livermore specifically and prefer a locally-based contractor, though both companies serve Alameda County broadly
- ✓ You're willing to conduct thorough due diligence through direct references and project site visits to verify solar installation capabilities that aren't documented in available reviews
- ✓ You prioritize a smaller-scale operation over a larger company, though you'll need to confirm actual company size and crew experience directly
Questions to Ask Before Hiring
- → Ask All On Electric And Solar for references from at least three recent solar installations similar to your project scope, and contact them to verify timeline adherence, permitting experience, and system performance
- → Ask All On Electric And Solar how many solar installations they've completed in the past two years and request photos or addresses of local projects you can view
- → Ask both companies about their current crew composition—how long installers have been with the company and their specific solar experience, not just general electrical work
- → Ask both contractors about their approach to handling permitting delays or unexpected roof conditions discovered during installation
The Bottom Line
Tesla is the clearer choice for most homeowners making a decision this week. Their 19-year track record is backed by verifiable customer feedback showing they deliver on timeline promises, handle complex installations competently, and navigate Alameda County permitting effectively. All On Electric And Solar has proper credentials and three fewer years of experience, but the critical gap is verification—you cannot assess their actual solar installation performance from available information. If you're considering All On Electric And Solar, plan to spend significant time checking references and viewing completed projects before signing. For a decision this week, Tesla offers documented reliability that All On Electric And Solar simply hasn't made verifiable.

Frequently Asked Questions
Tesla's extensive customer feedback suggests their larger scale doesn't prevent timely installations or responsive communication—customers specifically mention regular updates during permitting. However, you should ask both companies about their current project queue and how many installations their crews are managing simultaneously. All On Electric And Solar may offer more direct access to decision-makers, but verify this directly since their actual company size isn't documented.
Solar installations do involve electrical work, and dual licensing can be beneficial if you need panel upgrades or electrical system modifications. However, Tesla's solar specialization means they handle electrical components of solar systems routinely. The advantage would be clearer if you have separate electrical projects beyond the solar installation itself, so clarify what electrical work is actually included in each company's solar proposal.
This could indicate they've focused primarily on electrical work rather than solar, they're a smaller operation with fewer total projects, or they simply haven't collected customer feedback systematically. Ask them directly about their solar installation volume over the past few years and request verifiable references. The lack of reviews doesn't necessarily indicate poor work, but it does mean you'll need to verify their solar capabilities through other means.
Those three years span significant solar technology evolution and regulatory changes in California, which matters for current installation practices. More importantly, Tesla's documented customer feedback shows they've successfully navigated these changes while maintaining quality and timeline adherence. The experience gap is less about the number itself and more about the proven track record that accompanies it.

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.
