Consider Cinnamon Energy Systems if...
- ✓ Your project is specifically a solar panel system, battery backup installation, or heat pump HVAC system without anticipated electrical complications beyond standard panel upgrades.
- ✓ You value working with a contractor whose entire business model centers on solar installations, meaning their crews perform these installations daily and stay current on solar-specific permitting and utility requirements.
- ✓ You're planning a ground-mounted solar system or Tesla Powerwall integration where specialized experience with these specific products matters.
- ✓ Your home's existing electrical system is relatively modern and you don't anticipate needing troubleshooting or repairs beyond what's directly related to solar integration.
Consider Dollens Electric if...
- ✓ You need a contractor who can assess and address underlying electrical issues that solar installations commonly uncover, such as outdated panels, insufficient capacity, or code violations.
- ✓ You're planning multiple electrical projects beyond solar, such as adding an EV charging station, upgrading recessed lighting, or installing a standby generator, and prefer one contractor relationship.
- ✓ Quick response time is critical to your timeline, as customer feedback consistently highlights Dollens' ability to provide estimates within a day of contact.
- ✓ You value the high owner involvement noted in their operation, which typically means direct accountability and consistent oversight throughout the project.
- ✓ Your property has older electrical infrastructure where 20 years of troubleshooting experience could prevent mid-project complications.
Questions to Ask Before Hiring
- → Ask Cinnamon Energy Systems how they handle situations where existing electrical infrastructure needs upgrading beyond the standard panel work included in solar installations, and whether they subcontract that work or handle it in-house.
- → Ask Dollens Electric how many solar installations they complete annually compared to other electrical work, and request references specifically from recent solar projects similar in scope to yours.
- → Ask both contractors about their warranty coverage for solar-specific components versus electrical work, as this may differ between a specialist and generalist.
- → Ask about timeline expectations, particularly whether Dollens' noted quick response times translate to faster project completion for solar installations compared to Cinnamon's specialized workflow.
The Bottom Line
Choose Cinnamon Energy Systems if you're specifically installing solar panels, battery backup, or heat pump systems on a home with modern electrical infrastructure, where their daily specialization in these exact installations will provide the most streamlined experience. Choose Dollens Electric if your home has older electrical systems, you're planning multiple electrical projects beyond solar, or you value the troubleshooting depth that comes from 20 years solving diverse electrical problems. For most homeowners with straightforward solar projects and no anticipated electrical complications, Cinnamon's specialization is the better fit. For properties where electrical unknowns exist or comprehensive electrical capability matters, Dollens' veteran experience provides more comprehensive protection against mid-project surprises.

Frequently Asked Questions
It matters significantly depending on your home's condition. If your electrical panel is outdated, your wiring doesn't meet current code, or you discover problems during the solar installation process, Dollens' 20 years of general electrical experience means they can diagnose and fix those issues without stopping work or bringing in subcontractors. However, if your home's electrical system is modern and you only need solar installed, Cinnamon's daily focus on solar installations means their process is likely more streamlined for straightforward projects.
Specialization affects process efficiency more than system performance, since both contractors must meet the same permitting and utility interconnection standards. Cinnamon's advantage lies in handling solar-specific permitting, utility coordination, and battery integration with practiced efficiency. Dollens offers the advantage of identifying and addressing electrical issues that could affect long-term system reliability, drawing on two decades of troubleshooting experience across diverse electrical problems.
Dollens Electric handles both installations routinely and can coordinate the electrical load calculations to ensure your panel upgrade accommodates both systems efficiently in a single project. While Cinnamon could potentially coordinate with another contractor for the EV charger, having one company manage both installations simplifies scheduling, warranty questions, and ensures cohesive electrical design from the start.
The experience difference matters less than the type of experience. Cinnamon's 13 years focused exclusively on solar means they've likely completed more solar installations than Dollens despite fewer total years licensed. Dollens' 20 years provides broader electrical problem-solving ability but potentially fewer total solar projects. For complex solar designs or battery systems, Cinnamon's specialization is the relevant experience; for projects where electrical complications are likely, Dollens' veteran status in general electrical work becomes more valuable.

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.
