Alcor Solar
My family first used Alcor Solar when our first pool solar panels were installed in the 90's. We had the roof redone in 2013 and had updated pool solar panels installed then. We recently had Alcor com...
We were referred to Alcor Solar by our pool company and the referral was well justified. When they initially came to our home, they surveyed our roofs for the best panel location and measured the siz...
We got solar pool heating installed and every day in the spring, summer and fall our pool is at 80-85 degrees depending on where we set it. In the summer the pool can actually get too warm so we simp...
Consider West Coast Solar if...
- ✓ You need photovoltaic solar panels to generate electricity for your home or want to add battery storage like Powerwall systems to reduce reliance on the grid
- ✓ You value responsive communication during the sales and installation process, with customers consistently noting West Coast's no-pressure approach and thorough explanations
- ✓ Your project involves a tile roof and you want installers experienced in protecting existing roof structures during mounting work
- ✓ You need a contractor who handles the full permitting process, city inspections, and PG&E activation coordination
Consider Alcor Solar if...
- ✓ You specifically need solar pool heating rather than electrical generation, as this is Alcor's exclusive focus with 37 years of specialized experience
- ✓ You want a contractor with deep expertise in sizing thermal systems for pool applications and evaluating roof conditions for optimal panel placement
- ✓ You value long-term business relationships and need a company likely to be around for decades of future service, as evidenced by customers returning over 20-30 year periods
- ✓ You're willing to work around potential scheduling inconsistencies in exchange for specialized pool heating expertise not available from photovoltaic installers
Questions to Ask Before Hiring
- → For Alcor Solar: Ask how they handle appointment scheduling and what advance notice you'll receive for service calls, given customer feedback about timing challenges
- → For Alcor Solar: Request specific details about their communication practices and who will be your primary contact throughout the project
- → For West Coast Solar: Ask about their post-installation service response times and how they prioritize warranty work versus new installations
- → For either company: Confirm the warranty terms for both equipment and installation workmanship, and ask how service requests are tracked and scheduled
The Bottom Line
Your decision starts with identifying what technology you actually need. If you want to generate electricity for your home, reduce your utility bills, or add battery backup, West Coast Solar is your choice—Alcor doesn't offer these services. If you need pool heating, Alcor Solar is the specialist with 37 years focused exclusively on thermal pool systems. Within those parameters, West Coast Solar offers more consistent communication and customer service based on feedback, while Alcor brings unmatched longevity and specialization but with scheduling and communication inconsistencies you'll need to address directly. Contact the company that matches your technology need and ask the specific questions about their service practices before signing.

Frequently Asked Questions
No, these companies serve different markets entirely. West Coast Solar installs photovoltaic systems that generate electricity but does not work with pool heating. Alcor Solar installs solar thermal pool heating systems exclusively and does not install photovoltaic panels or battery storage. You would need to hire both companies separately if you want both technologies.
Alcor's 37 years demonstrates successful business longevity and technical expertise in pool heating, with customers returning across decades. However, recent feedback indicates inconsistent scheduling practices and communication style issues that are separate from their technical competence. Long business tenure doesn't automatically translate to modern customer service practices, and this appears to be an operational weakness despite their technical knowledge.
West Coast Solar customers report installations often completed in a single day, though the full process from deposit to PG&E activation can extend several weeks due to permitting and inspection requirements they handle on your behalf. Alcor Solar's installation timeline isn't clearly detailed in reviews, but you should ask directly about their current scheduling given customer feedback about appointment timing challenges.
West Coast Solar provides warranty service, inverter replacements, and system monitoring, though some customers report delays reaching the service department or scheduling repairs. Alcor Solar has maintained customer relationships for decades, suggesting they provide ongoing service, but the inconsistent communication patterns noted in reviews make it important to clarify their current service protocols and response commitments upfront.

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.
