Consider Revolving Power Solar if...
- ✓ You're installing a Tesla or other EV charger as a standalone project and want a specialist focused specifically on this technology with competitive pricing
- ✓ Your project is straightforward solar installation on a newer home without complex electrical integration issues
- ✓ You're willing to verify your homeowner's insurance covers contractor injuries and accept the liability risk associated with missing workers comp
- ✓ Quick response time and frequent communication throughout the project are top priorities for you
Consider Four Ace Electrical Services if...
- ✓ Your electrical project extends beyond solar or EV charging—panel upgrades, rewiring, troubleshooting, or any combination of electrical work
- ✓ You want workers compensation protection to avoid potential liability if someone is injured during your project
- ✓ Your home is older and may have hidden electrical issues requiring experienced diagnostic skills to identify code violations or safety hazards
- ✓ You value a contractor with nearly two decades of handling complications, coordinating inspections, and providing honest assessments that could save you money
Questions to Ask Before Hiring
- → Ask Revolving Power Solar directly about current liability insurance coverage and confirm with your homeowner's policy whether you're protected if a contractor without workers comp is injured on your property
- → Ask Revolving Power for references from solar or EV projects completed in the past year, specifically asking those homeowners about any complications that arose
- → Ask Four Ace whether they also handle solar installations or if they'd need to subcontract that portion if you're considering combined electrical and solar work
- → Ask both companies for detailed written estimates that specify permit coordination, inspection scheduling, and timeline commitments
The Bottom Line
For most homeowners, Four Ace Electrical Services is the safer choice—18 years of experience means they've solved problems Revolving Power hasn't encountered yet, their workers comp coverage protects you from liability, and their honest assessment approach could save you money despite potentially higher quotes. Choose Revolving Power only if you're hiring them for straightforward solar or EV charging work, you've confirmed your insurance covers contractor injuries, and you've checked references from their limited project history. If your project involves any complexity, older home electrical systems, or combines multiple scopes of work, Four Ace's veteran expertise significantly reduces your risk of costly surprises.

Frequently Asked Questions
For a straightforward charger installation on a newer home with adequate panel capacity, probably less so—this is relatively standardized work. However, if your panel needs upgrading, your home has older wiring, or you're adding solar simultaneously, Four Ace's experience diagnosing hidden issues and coordinating complex electrical work becomes significantly more valuable. Many EV charger projects reveal underlying electrical inadequacies that require broader expertise.
This is a genuine liability issue you should take seriously. If a worker is injured at your property and the contractor lacks workers comp, your homeowner's insurance may become the primary coverage, potentially leading to claims against your policy. Before hiring any contractor without workers comp, call your insurance agent to understand your exposure and get confirmation in writing about what's covered.
Four Ace lists EV charging station installation among their services and holds an electrical contractor license that permits solar work, but their review feedback focuses on traditional electrical projects rather than solar arrays. Ask them directly about their solar installation experience and recent projects. Their broad electrical expertise is valuable, but if they subcontract solar work, you'd need to vet that subcontractor separately.
That depends entirely on your project scope and risk tolerance. For a simple, code-compliant EV charger installation where you've verified your insurance coverage, competitive pricing from a responsive specialist may make sense. For solar installations involving roof penetrations, electrical integration, and long-term warranty concerns, or any project on an older home, the experience gap and insurance protection likely justify Four Ace's pricing.

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.
