Consider Earth Electric if...
- ✓ Your roof is in good condition with at least 10-15 years of remaining life and doesn't need replacement before solar installation
- ✓ You're installing an electric vehicle charging station alongside or instead of solar panels, which is Earth Electric's specialized area
- ✓ You prefer a company focused exclusively on electrical and solar technology rather than divided attention across roofing and solar trades
- ✓ Your project involves complex electrical panel upgrades or limited service capacity requiring specialized electrical expertise
Consider Simmitri if...
- ✓ Your roof needs replacement or significant repair before or during solar installation, allowing one company to coordinate both disciplines
- ✓ You want the deepest possible experience base, particularly valuable if your home has unusual construction or you're in a complex permitting jurisdiction
- ✓ You need gutter work alongside roofing and solar, keeping all exterior work with a single contractor
- ✓ Your project timeline benefits from not coordinating between separate roofing and solar companies, which can add weeks to scheduling
Questions to Ask Before Hiring
- → Ask Earth Electric how they coordinate with roofers if roof issues are discovered during solar installation or who they recommend for roof assessment beforehand
- → Ask Simmitri whether the same crew handles both roofing and solar work or if they use separate specialized teams for each discipline
- → Request references from both companies for projects similar in complexity to yours, particularly if you have tile roofing or limited electrical panel capacity
- → Ask how each company handles warranty claims when issues could involve both roof integrity and solar system performance
The Bottom Line
If your roof is sound and your project is solar, battery storage, or EV charging, Earth Electric's 11 years of established expertise and electrical specialization serve you well at likely competitive pricing. If your roof needs replacement within the next decade or you're unsure of its condition, Simmitri's 27 years of veteran experience and integrated roofing-solar capability eliminate coordination headaches and provide deeper institutional knowledge for complex situations. The decision centers on whether you need roofing services rather than which company does better solar work, as both demonstrate strong technical capability and customer satisfaction in solar installations.

Frequently Asked Questions
For straightforward installations on newer homes with simple roof lines and adequate electrical capacity, both companies have sufficient expertise. The experience gap becomes meaningful when unexpected issues arise, such as discovering outdated wiring, structural concerns, or unusual permitting requirements. Simmitri's 27 years means they've likely encountered and resolved your specific situation before, while Earth Electric's 11 years still provides substantial problem-solving capability for most residential projects.
Not necessarily. If your roof is confirmed to be in good condition with adequate remaining life, Earth Electric's solar-focused expertise may serve you equally well. However, Simmitri's roofing knowledge helps them identify potential roof issues during the assessment phase that a solar-only contractor might miss, potentially preventing problems years down the line when repairs become more complicated with panels installed.
While Earth Electric likely has roofing partners they coordinate with, you'll be managing two separate contracts, schedules, and warranty relationships. This creates coordination overhead and potential disputes if roof issues emerge after solar installation. If you know you need both services, Simmitri's integrated approach eliminates these complications and provides single-point accountability.
Both companies handle battery installations, but Earth Electric specifically lists Tesla Powerwall in their project types and positions battery storage as a core specialty. Their solar-exclusive focus suggests potentially deeper familiarity with the latest battery technologies and utility rate structures that maximize storage value. Ask both companies about their recent battery installations and how they design systems for your specific utility rates and backup needs.

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.
