Element Power Systems
Bryan is an awesome guy to work with and have on your property... expect him and his crew to provide quality service

Consider Element Power Systems if...
- ✓ You want a contractor whose entire 16-year track record centers exclusively on solar photovoltaic systems rather than diversified energy services
- ✓ Your project is solar-only and you already have relationships with HVAC contractors or don't need heating and cooling work
- ✓ You value detailed education specifically about solar components, system sizing, and production optimization from a specialist
- ✓ You're working with an older roof that may need replacement first and want a solar contractor experienced in coordinating sequencing with roofing companies
Consider Green Air Heating And Air Conditioning if...
- ✓ You're planning to combine solar with battery storage like Tesla Powerwall, HVAC replacement, or ductwork modifications in one coordinated project
- ✓ You prefer a single contractor managing permitting and installation across multiple interconnected systems rather than coordinating separate specialists
- ✓ You want a company you can call back for ongoing HVAC maintenance, thermostat issues, and heating repairs in addition to solar service
- ✓ You value a business model where customers return for sequential upgrades, suggesting confidence in multi-phase project handling
Questions to Ask Before Hiring
- → Ask Element Power Systems about their protocol for long-term system monitoring support and responsiveness to performance issues that emerge years after installation
- → Ask Green Air what percentage of their current business is solar-focused versus HVAC, and whether the same crew handles both or if they have dedicated solar installers
- → Ask both contractors how they handle warranty claims for solar components and whether they stock parts for the specific inverter and panel brands they'll install
- → Ask both about their approach to roof assessment before solar installation and at what point they recommend involving a roofing contractor
The Bottom Line
If you're installing solar panels only and want a contractor whose entire 16-year business has been dedicated to photovoltaic systems, Element Power Systems offers focused expertise, though you should directly address the post-installation support concerns raised by some customers. If you're planning solar alongside battery storage, HVAC upgrades, or want a single contractor for future heating and cooling service calls, Green Air's integrated energy approach provides coordination advantages despite being newer to solar specifically. Neither has a clear licensing or protection advantage given similar bonding and workers comp coverage. Schedule consultations with both, ask Element Power Systems about their monitoring support improvements, and ask Green Air what percentage of their current projects involve solar to gauge their active commitment to photovoltaic work.

Frequently Asked Questions
It matters for project scope definition. If you're certain you only need solar panels installed, Element Power Systems' exclusive focus means every project they've completed for 16 years has been solar. If you're considering battery backup or know your HVAC system is aging, Green Air's integrated approach means one permitting process, one project manager, and one warranty coordinator. Ask Green Air how long they've been doing solar specifically and how many installations they complete annually.
Element Power Systems receives specific mentions for flexibility coordinating with roofing contractors, likely because solar-only specialists regularly encounter this sequencing issue. Green Air's reviews mention roof replacement as part of their project portfolio, suggesting they may handle roofing directly or through partnerships. Ask Element Power Systems for recent examples where they delayed solar for roof replacement, and ask Green Air whether they subcontract roofing or coordinate with your chosen roofer.
It matters significantly because solar systems require 25+ years of monitoring and occasional troubleshooting. Some customers noted responsiveness issues when equipment monitoring problems arose years after installation. Ask Element Power Systems directly about their monitoring platform, typical response time for performance issues, and whether they proactively alert customers to production drops. This is a legitimate question to address before signing.
Potentially, if electrical panel upgrades or service capacity increases are needed, which solar installations sometimes require. Green Air's electrical work experience through HVAC projects may streamline this. However, their bandwidth may be split across service calls for furnace repairs and AC maintenance. Ask them how they schedule and prioritize solar installation projects versus ongoing HVAC service demands.

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.
