Customer Reviews
Trulysun Energy
Trulysun installed solar at my home. They worked through supplier challenges, city permitting and with PGE. Couldn’t be happier with their professionalism and diligence!
Super impressed with David Rubio from Trulysun Energy and would highly recommend. For the last 3 years my solar system has been great, but intermittently shutting down during the rain. The first four...

Luminalt Solar Energy Solutions
We had Luminalt Solar install 29 solar panels on our Victorian in Bernal Heights ten years ago. We’re thrilled with the installation and savings on our PG&E bill every month! Our service rep, Kayla,...
Pretty smooth process from start to finish. Zero surprises.
The Luminalt team was very easy to work with, and the end result is functioning perfectly.
Consider Trulysun Energy if...
- ✓ You're working through a solar equipment provider who has already selected Trulysun as their installation partner and you're comfortable with that subcontractor relationship structure.
- ✓ Your project is straightforward with no unusual permitting complications, and you value direct owner involvement throughout the installation process.
- ✓ Budget is a primary concern and Trulysun offers significantly lower pricing, though you should verify this directly as pricing wasn't provided in the data.
- ✓ You specifically need EV charger installation bundled with solar work, as this appears more prominently in Trulysun's service mix.
Consider Luminalt Solar Energy Solutions if...
- ✓ Your home is a Victorian or has architectural complexity that requires experienced navigation of San Francisco building requirements and potential structural challenges.
- ✓ You're installing a solar plus battery storage system where integration complexity benefits from two decades of institutional knowledge.
- ✓ You want the highest probability of smooth permitting and inspection processes without timeline extensions or administrative complications.
- ✓ Long-term system performance matters significantly to you, and you value feedback showing systems performing well years after installation with a company that will still be around for service.
Questions to Ask Before Hiring
- → Ask Trulysun specifically how they handle permitting inspection failures and what their typical timeline is from installation to final approval, given customer reports of challenges in this area.
- → Ask Luminalt about their current project backlog and lead times, as established companies with strong reputations may have longer waits that affect your timeline.
- → For either company, request references from projects completed in the past year on homes similar to yours in age and architectural style.
- → Clarify with Trulysun whether they'll be the primary contractor or working as a subcontractor, and how that affects your warranty and service relationship.
The Bottom Line
For most San Francisco homeowners, Luminalt Solar Energy Solutions is the stronger choice based on 21 years of proven solar-specific experience, consistently smooth project execution, and demonstrated success with complex installations. Their two-decade track record navigating San Francisco's permitting environment directly addresses the administrative challenges that Trulysun customers report experiencing. Consider Trulysun only if you're already working through an equipment provider who has selected them, your project is genuinely straightforward, or they offer substantially lower pricing that justifies accepting more project timeline risk. If your home is older, architecturally complex, or you're installing battery storage, Luminalt's veteran expertise is worth the investment.

Frequently Asked Questions
For a straightforward installation on a newer home with no complications, the gap matters less. However, even standard projects in San Francisco involve navigating city permitting and utility coordination, where Luminalt's customer feedback shows consistently smooth processes while Trulysun's reveals ongoing challenges. Experience particularly matters when unexpected issues arise during installation, which happens frequently with San Francisco's older housing stock.
Many newer solar installers partner with equipment manufacturers or solar sales companies who handle customer acquisition and financing while the installer handles technical work. This isn't inherently negative, but it can create confusion about warranty coverage and who to contact for service issues. Ask Trulysun directly whether you'll contract with them or with an equipment provider, and how that affects your long-term service relationship.
While pricing wasn't provided in the data, veteran contractors often charge more but deliver value through fewer change orders, faster permitting approval, and lower risk of costly mistakes. Luminalt's customer feedback shows installations completed efficiently without the timeline extensions that Trulysun customers report. Factor in the cost of your time dealing with extended permitting issues when comparing quotes.
Trulysun does perform varied work including troubleshooting and electrical services, but their customer feedback doesn't highlight successful complex installations the way Luminalt's does. With only four years of experience, they've had fewer opportunities to develop expertise with challenging properties. If your project involves architectural complexity or advanced battery integration, Luminalt's proven track record with these specific scenarios provides substantially more confidence.

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.
