Questions to Ask Before Hiring
- → Ask Element Power Systems specifically how they handle equipment monitoring issues and what their response timeline is for post-installation support calls
- → Ask Diablo Solar Services about their scheduling availability during peak seasons, as some customers note challenges booking during busy periods
- → Ask both companies how long their current installation crews have been with the company to assess workforce stability
- → Ask Element Power Systems for references from customers whose systems have been operating for at least 3-5 years to understand long-term support patterns
The Bottom Line
Diablo Solar Services is the stronger choice for most homeowners. Their 42 years of experience, proven track record of maintaining customer relationships for decades, and comprehensive service capabilities including repairs and maintenance provide significantly better long-term value than Element Power Systems' installation-focused approach. The post-installation support concerns with Element Power Systems are particularly troubling given that solar systems require 20-25 years of service. Unless you specifically need Element Power Systems' scheduling availability right now and are confident managing long-term system monitoring yourself, Diablo's depth of experience and service commitment makes them the safer investment for a solar project that must perform reliably for decades.

Frequently Asked Questions
Yes, substantially. Diablo's 42 years means they've installed and maintained systems through multiple technology generations, giving them deeper troubleshooting skills when issues arise. More critically, their customer feedback shows they've maintained relationships for 10 to 20 years, while Element Power Systems faces specific concerns about being responsive years after installation. If you need ongoing support, this experience gap is significant.
Diablo Solar Services still holds advantages even for photovoltaic-only projects. Their four decades of experience, proven long-term customer relationships, and emphasis on repairs over replacements benefit any solar system owner. Element Power Systems offers strong educational consultations during installation, but the post-installation support concerns are relevant regardless of system type.
Customer feedback specifically mentions responsiveness issues with equipment monitoring problems that emerged years after installation. Solar systems require 20-25 years of support, and if your installer isn't responsive when inverters fail or monitoring systems go offline, you lose the financial benefits you paid for. Ask Element Power Systems directly about their service call response times and warranty support processes.
Some Diablo customers note scheduling challenges during peak periods, but this likely reflects high demand from their established customer base. Their willingness to repair systems rather than push replacements and their documented decades-long customer relationships suggest the wait may be worthwhile. If your project timeline is urgent, discuss scheduling upfront and consider whether Element Power Systems' availability outweighs the post-installation support concerns for your situation.

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.
