Customer Reviews
Grid Alternatives
Great install but very difficult to get in touch with the office for follow up. They never answer their phones, respond to emails or voice messages. I had to do a surprise visit .
Excellent customer support
GRID Alternatives was so great to work with. They qualified us for a No Cost solar system on our home, which included needing to have our main electric panel upgraded from 100Amp to 125 Amp. They comp...
Save A Lot Solar
They did my panels a few years ago and I could not be happier with the service, and the product.
Locally run, great people, skilled at designing a small system that the big players couldn’t be bothered with. On time and on budget with no surprises.
Jon and team were great to work with.
Consider Grid Alternatives if...
- ✓ You qualify for Grid Alternatives' income-based free solar program and meet their eligibility requirements for no-cost installation
- ✓ Upfront cost is your primary barrier to going solar, and you're willing to work within their timeline and approval process
- ✓ You're comfortable with a more transactional installation experience and don't anticipate needing extensive post-installation support
- ✓ You value the social mission of a nonprofit bringing solar access to underserved communities while training the next generation of solar installers
Consider Save A Lot Solar if...
- ✓ You're paying for solar installation and want responsive communication throughout the project and afterward when questions arise
- ✓ Your property has complications like an older roof, strict local permitting, or requires custom system design rather than standard configurations
- ✓ You prefer working directly with the owner during consultation to discuss technical details and get personalized recommendations
- ✓ You want a contractor who consistently responds to emails and calls, with feedback showing reliable accessibility for follow-up questions
Questions to Ask Before Hiring
- → Ask Grid Alternatives what their typical response time is for post-installation questions and whether they have a dedicated support line for system monitoring issues
- → Ask Save A Lot Solar for their warranty terms and how they handle service calls after installation is complete
- → If considering Grid Alternatives, clarify the timeline from approval to installation to system activation, as experiences vary significantly
- → Ask both companies about their experience with your specific roof type and any additional electrical work your home may require
The Bottom Line
If you qualify for Grid Alternatives' income-based program, the cost savings are transformative—free solar versus thousands of dollars. However, understand that post-installation communication challenges are a documented pattern, so confirm their support process before committing. For paying customers, Save A Lot Solar offers the complete package: competitive pricing, 14 years of solid experience, owner involvement, and consistently responsive communication that Grid Alternatives customers report missing. The six-year experience gap favoring Grid Alternatives doesn't overcome Save A Lot Solar's clear advantage in accessibility and personalized service for traditional contractor relationships. Choose based on whether you qualify for free installation and can work within Grid Alternatives' structure, or whether you need the attentive, ongoing support Save A Lot Solar consistently delivers.

Frequently Asked Questions
Grid Alternatives operates specifically as a nonprofit providing no-cost solar to qualifying low-income households. If you don't meet their income eligibility requirements, you'll need a traditional contractor like Save A Lot Solar. Their entire service model, including volunteer integration and timeline structure, is built around their nonprofit mission rather than standard contracting.
While Grid Alternatives has more years licensed, Save A Lot Solar's reviews show significantly better communication accessibility and personalized service. For most paying customers, responsive communication for troubleshooting and ongoing support matters as much as installation experience. Grid Alternatives' longer history serves their high-volume nonprofit model well, but Save A Lot Solar's approach fits traditional contractor-client relationships better.
Multiple Grid Alternatives customers specifically mention difficulty reaching the office by phone or email for post-installation questions. This is a documented pattern worth addressing directly with them before proceeding. Ask about their support structure, typical response times, and whether they have dedicated staff for system monitoring questions versus new installation coordination.
Customer feedback consistently mentions Save A Lot Solar's quotes coming in below competitors while using quality equipment like REC panels and Enphase systems. They appear to compete on price while maintaining responsive service, though obviously any paid installation will cost significantly more than Grid Alternatives' free program for qualifying households. Get quotes from both companies if you're eligible for Grid Alternatives to understand the actual cost difference for your specific project.

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.
