Consider Future Energy Savers if...
- ✓ You're installing a solar panel system or adding battery backup to your home, where Future Energy Savers' 41 years of solar-specific experience directly applies to system design, equipment selection, and navigating utility interconnection requirements.
- ✓ You value working with in-house installation teams rather than subcontractors, which Future Energy Savers explicitly uses for their solar projects.
- ✓ Your project involves coordinating roofing work alongside solar installation, as the company handles associated roof repairs or replacement as part of comprehensive solar projects.
- ✓ You want a contractor who has worked through multiple generations of solar technology and knows how to troubleshoot issues specific to photovoltaic systems and battery storage.
Consider Main Stream Electric if...
- ✓ You need traditional electrical work such as panel upgrades, circuit installations, outlet repairs, or diagnostic troubleshooting where Main Stream Electric's 18 years of focused electrical experience is directly relevant.
- ✓ You're managing a commercial property requiring electrical maintenance or upgrades, as Main Stream Electric has demonstrated experience with retail and hotel properties.
- ✓ You value a track record of repeat customers and high owner involvement, which Main Stream Electric's review pattern suggests across various electrical projects.
- ✓ Your timeline requires prompt service for electrical repairs or smaller installations, where Main Stream Electric's scheduling flexibility for non-solar work may offer faster response than a solar company's project pipeline.
Questions to Ask Before Hiring
- → If considering Future Energy Savers for electrical work without solar: Ask whether they perform standalone electrical projects or if their license and crews are exclusively focused on solar installations.
- → If considering Main Stream Electric for solar: Ask directly about their solar installation experience, including how many systems they've installed and whether they coordinate permitting and utility interconnection in-house.
- → For either company: Request references from projects matching your specific scope, whether that's a complete solar system with battery backup or a 200-amp panel upgrade with circuit work.
The Bottom Line
This comparison only makes sense if you're unclear whether your project is solar installation or traditional electrical work. If you're installing solar panels or adding battery backup, Future Energy Savers is the appropriate choice with 41 years of specialized solar experience, in-house installation teams, and demonstrated expertise coordinating the complete solar process from permitting through utility activation. If you need panel upgrades, rewiring, circuit work, or electrical repairs without solar components, Main Stream Electric brings 18 years of focused electrical expertise with strong customer relationships and prompt service. Don't hire a solar company for electrical repairs, and don't hire a general electrician for a solar system unless they can demonstrate substantial solar project experience.

Frequently Asked Questions
While Main Stream Electric holds an electrical license that technically permits solar work, their business focuses on traditional electrical services without indication of solar specialization. Solar installation requires expertise in system design, structural mounting, inverter configuration, battery integration, utility interconnection applications, and solar-specific permitting that goes well beyond standard electrical work. Ask them directly about their solar project experience before proceeding.
For solar projects specifically, 41 years represents experience across multiple technology generations, from early photovoltaic systems through modern high-efficiency panels and lithium battery storage. This tenure means they've navigated decades of evolving building codes, utility requirements, and equipment changes. For a solar installation, this depth of specialized experience is meaningfully different from a newer solar company or a general electrician adding solar services.
Future Energy Savers coordinates all electrical components as part of their solar installations, including connecting panels to your electrical system, installing inverters and battery backups, and upgrading your main panel if needed for solar integration. This integrated approach ensures all components work together and meet solar-specific code requirements. If you need separate electrical upgrades unrelated to solar, Main Stream Electric would be appropriate for that standalone work.
Both maintain the standard $25,000 California contractor bond and workers compensation insurance, providing equivalent statutory protection. Future Energy Savers' 41-year operating history does suggest business stability and established relationships with suppliers, permitting offices, and utilities that newer companies lack. However, for your direct financial protection on a specific project, the bond and insurance coverage are identical.

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.
