Consider Calpro Solar if...
- ✓ You want a focused solar specialist with nearly four decades of experience navigating complex installations, roof conditions, and system troubleshooting
- ✓ The consultation process matters to you and you prefer educational discussions without high-pressure sales tactics
- ✓ Post-installation support is a priority, especially if you anticipate needing responsive service for system questions or issues
- ✓ Your project is solar-focused without additional electrical work needs, and you value consistent administrative follow-through including rebate processing
Consider Synergy 768 if...
- ✓ You need EV charging station installation or other electrical work coordinated with your solar project in a single contract
- ✓ You value direct owner accessibility and have worked successfully with contractors on multiple repeat projects
- ✓ Your project timeline and budget are firm requirements, and you appreciate contractors who deliver within established parameters
- ✓ You're comfortable handling some administrative follow-up yourself, such as checking on rebate paperwork status directly
Questions to Ask Before Hiring
- → Ask Synergy 768 specifically how they track rebate paperwork submissions and what timeline you should expect for completion, given customer feedback about administrative gaps
- → Ask Calpro Solar about their experience with roof conditions similar to yours, particularly if your roof is older or may need assessment for structural capacity
- → Request references from both companies for projects completed in the past 12 months to gauge current service levels
- → If considering Synergy 768 for multiple service types, ask which crew members handle which aspects and whether the same team coordinates all work
The Bottom Line
For most solar-only installations, Calpro Solar's 37-year veteran status, consistently positive feedback about no-pressure consultations, and reliable post-installation support make them the stronger choice. Their focused specialization and three times more experience provide meaningful advantages in handling complications and long-term service needs. Choose Synergy 768 if you specifically need EV charging or other electrical work coordinated with your solar installation, and you're willing to stay on top of administrative details like rebate paperwork yourself. If your project is purely solar and battery backup, Calpro Solar's track record and service consistency outweigh Synergy 768's broader capabilities. Schedule consultations with both, but pay attention to whether Calpro Solar's consultation style and veteran experience feel worth the potential trade-off of not bundling electrical services.

Frequently Asked Questions
Yes, particularly if complications arise. Calpro Solar's 37 years means they've seen multiple generations of solar technology, changing building codes, and utility interconnection requirements. This experience becomes valuable when diagnosing roof conditions, handling permitting issues, or troubleshooting system performance. For straightforward installations on newer homes, the gap matters less, but for older properties or complex roof configurations, veteran experience reduces risk.
It's a legitimate consideration, especially regarding solar rebates which can represent significant savings. While customers praise Synergy 768's installation quality and timeline adherence, several specifically mention needing to follow up on paperwork completion. Ask directly about their rebate processing timeline and who's responsible for tracking submissions. If you're comfortable managing administrative details yourself, this may be manageable.
Synergy 768 explicitly specializes in EV charging station installations alongside solar work, which means one contractor handles permitting, coordination, and warranty for both systems. Calpro Solar focuses exclusively on solar and battery backup. If you want bundled services under one contract, Synergy 768's broader electrical capabilities offer logistical advantages despite their shorter operational history.
Multiple Calpro Solar customers specifically contrasted their consultation experience favorably against other solar companies they considered, suggesting this is a meaningful difference in the industry. If you've felt pressured by other solar sales processes, this indicates a different approach. Synergy 768 customers mention strong owner involvement in consultations but don't specifically highlight the absence of sales pressure as a distinguishing feature.

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.
