Consider Cinnamon Energy Systems if...
- ✓ Your project centers on solar and battery systems without roofing needs, particularly if you're interested in heat pump HVAC or mini-split integration as part of a broader electrification strategy
- ✓ You're in Los Gatos or northern Santa Clara County and value working with a locally established contractor with 13 years of area-specific permitting relationships
- ✓ You want specialized focus on modern solar technology and battery systems like Tesla Powerwall rather than a contractor splitting attention between roofing and solar disciplines
- ✓ Your home requires detailed electrical panel upgrades or complex system design for challenging roof layouts where solar-specific engineering expertise matters
Consider Simmitri if...
- ✓ Your roof needs replacement or significant repair before or during solar installation, making Simmitri's ability to handle both disciplines under one contract valuable for coordination and warranty clarity
- ✓ You're in Morgan Hill, Gilroy, or southern Santa Clara County where Simmitri is based
- ✓ The 27-year track record and veteran status provide reassurance for a major investment, particularly if your project involves older home challenges or complex structural considerations
- ✓ You value high owner involvement and detailed documentation practices, including photographic evidence of work completed throughout the project
Questions to Ask Before Hiring
- → Ask Cinnamon Energy about their approach to roof assessments before solar installation and who they partner with if roofing work is needed
- → Ask Simmitri about their heat pump and mini-split installation capabilities if whole-home electrification beyond solar is part of your plan
- → Request references from both contractors for projects similar in scope to yours, specifically asking about permitting timelines in your city
- → Confirm which crew members will be on your project and how long they've been with each company
The Bottom Line
Choose Simmitri if your project involves roofing work alongside solar installation or if the 27-year veteran status provides the reassurance you need for this major investment, particularly for older homes or complex situations. Their dual capability eliminates contractor coordination headaches and warranty confusion. Choose Cinnamon Energy Systems if your project is solar-focused without roofing needs, especially if you're pursuing broader home electrification with heat pump or mini-split systems where their specialization adds value. Both contractors maintain proper licensing, insurance, and bonding with strong customer feedback on project management. The decision hinges primarily on whether you need roofing services and whether you value veteran breadth or specialized depth in solar and electrification technology.

Frequently Asked Questions
For straightforward installations on newer homes with sound roofs, both contractors demonstrate competence based on customer feedback. The experience gap becomes significant if your project involves complications like older home structural concerns, challenging permit situations, or the need to diagnose hidden issues before installation. Simmitri's 27 years means they've encountered and solved a wider range of uncommon problems.
Simmitri's dual capability is a clear advantage for projects requiring both roofing and solar work, eliminating coordination between separate contractors and providing single-source warranty coverage. However, if your roof truly needs replacement, get competing bids on the roofing portion specifically, as a roofing specialist might offer better pricing. The convenience and warranty simplification may still justify Simmitri's approach.
Both handle battery installations, but Cinnamon Energy's specialization in Tesla Powerwall and battery systems suggests deeper focus on this technology. If you're adding storage to an existing system they didn't install, ask each contractor about their experience integrating with your specific inverter and panel configuration. Simmitri's longer history means they've likely worked with more legacy systems.
Simmitri shows high owner involvement, which typically means more direct oversight and accountability throughout your project. Cinnamon Energy's owner involvement is unclear from available data, so ask directly who will manage your project and handle any issues that arise. For major investments like solar installations, knowing you can reach decision-makers quickly matters when timeline or technical questions emerge.

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.
