Consider Element Power Systems if...
- ✓ You want an educational approach where the contractor takes significant time explaining solar technology, component selection, and system functionality throughout the process
- ✓ Your roof is already in good condition and you prefer selecting your own roofing contractor if any work is needed before installation
- ✓ You value a company with high owner involvement that specializes exclusively in solar photovoltaic work without diversification into other trades
Consider High Definition Solar if...
- ✓ Your roof may need repairs or replacement before solar installation and you want one contractor handling both to avoid coordination headaches and warranty confusion
- ✓ You're concerned about being oversold on system capacity and want a contractor known for sizing systems to actual usage patterns rather than maximizing panel counts
- ✓ You value proven long-term service relationships with documented support for systems installed over a decade ago, including equipment failures and expansions
- ✓ You prefer efficient installations completed quickly, often in a single day, with responsive follow-up to explain system operation
Questions to Ask Before Hiring
- → Ask both companies about their typical response time for post-installation service calls and whether they have dedicated service staff separate from installation crews
- → If considering Element Power Systems, ask which roofing contractors they typically coordinate with and who manages the interface between roof and solar work
- → If considering High Definition Solar, ask whether the same crews handle both roofing and solar work or if they have separate specialized teams
- → Ask both companies how they size systems and request an explanation of why they're recommending a specific panel count for your actual electricity usage
The Bottom Line
High Definition Solar presents a more complete service package for most homeowners, particularly if roof work might be needed. Their dual solar and roofing capabilities, documented service continuity spanning over a decade, and customer-reported approach to right-sizing systems address the practical realities of solar ownership. Element Power Systems offers value if you specifically want an educational experience and already have a preferred roofing contractor, but their coordination model adds complexity. For a straightforward decision this week, High Definition Solar's proven track record of supporting systems installed as far back as 2012, combined with their ability to handle both trades, makes them the safer choice for homeowners wanting comprehensive, long-term solar service from one contractor.

Frequently Asked Questions
Yes, it matters significantly for warranty clarity and project coordination. When roof issues emerge after solar installation, having one company responsible for both eliminates finger-pointing about whether leaks originate from roofing work or solar panel mounting. High Definition Solar's dual capability means one point of contact and unified warranties. With Element Power Systems, you'll coordinate separate contractors, which adds complexity but gives you roofing contractor choice.
Post-installation service challenges appear in feedback for both companies, particularly for issues arising years after installation. This is common in solar as companies prioritize new installations over older system support. The key difference is High Definition Solar shows documented service relationships spanning over a decade with multiple examples of addressing inverter failures and expansions, suggesting established service infrastructure. Ask both companies directly about their service department staffing and typical response times.
Multiple customers note that High Definition Solar recommended smaller systems matched to actual electricity usage rather than maximizing panel counts. This approach saves upfront costs and prevents oversized systems that generate more power than you can use or sell back effectively. Element Power Systems' educational approach likely covers sizing as well, but the pattern isn't as explicitly documented in customer feedback. Ask both companies to justify their recommended system size based on your usage history.
That depends on your learning style and project complexity. If you're technically inclined, want to deeply understand your solar investment, and your roof is already sound, Element Power Systems' teaching approach adds value. However, if you need roofing work, prefer streamlined project management, and want proven long-term service support, High Definition Solar's comprehensive model may outweigh the educational emphasis. Both companies appear competent at installation quality itself.

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.
