Why Your Solar Installer Choice Matters Most
Choosing a solar installer is a 25-year relationship, and under NEM 3.0, the stakes are higher than ever. The wrong choice can turn a wise investment into a costly nightmare. A poorly vetted installer can lead to:
- Financial Loss: An improperly designed system for NEM 3.0 will fail to maximize your self-consumption, leading to disappointing savings and a much longer payback period.
- Installation Failures: Poor workmanship can lead to dangerous electrical issues, roof leaks, or faulty battery integration.
- Voided Warranties: Improper installation can void the manufacturer warranties on your expensive panels, battery, and inverters.
- “Ghost” Companies and Long-Term Headaches: Many smaller installers go out of business, leaving homeowners with an “orphaned” system and no one to call for service or warranty support.
Conversely, a top-tier solar company ensures a seamless process, a high-quality, resilient installation, maximized savings, and peace of mind for the entire lifespan of your system.
A Look at Some Top Solar Companies in California
To help you begin your research, here is a look at some of the top solar installers that serve homeowners in California. This is not an exhaustive list, and the best choice for you will depend on your specific needs and location.
Company | Strengths | Things to Consider |
SunRun | Large national company with extensive experience and multiple financing options (including popular leases and PPAs). | As a large company, customer service experiences can sometimes be less personal than with a local installer. |
Momentum Solar | Known for its high level of customer service and providing a concierge-like experience from start to finish. | Primarily focused on high-quality purchased systems, which may have a higher upfront cost. |
Venture Solar | Strong reputation for quality installations and customer service, with a growing presence in the California market. | Newer to the CA market compared to some legacy installers. |
ESD Solar | Strong reputation for quality installations and expertise in both solar and battery storage systems. | May have a more limited service area within California compared to larger national brands. |
Current Home | California-based company specializing in integrated solar and battery backup systems, with a focus on energy resilience for PSPS events. | Expertise is heavily focused on battery systems, which may be more than what some homeowners are looking for. |

State-Specific Considerations for California Installers
California’s energy market demands specific expertise. When choosing an installer, ensure they have:
- NEM 3.0 & Battery Expertise: This is non-negotiable. A top CA installer must be an expert at designing solar-plus-storage systems that are optimized for your home’s unique energy usage patterns to maximize self-consumption and savings.
- SGIP Knowledge: They must have experience with the Self-Generation Incentive Program (SGIP) application process to ensure you successfully claim your battery rebate.
- Local Utility Knowledge: They need a thorough understanding of the interconnection processes for PG&E, SCE, and SDG&E.
National vs. Local Solar Companies
Homeowners in California have a wide choice of both large national brands and smaller local installers. Each has potential advantages:
- National Companies: Often have more financing options and significant buying power that can sometimes lower equipment costs.
- Local Companies: May offer more personalized customer service and a deeper understanding of your specific city’s permitting process.
Ultimately, neither is inherently better. The most important factors are a company’s commitment to quality, customer service, and local expertise. EcoGen America’s network includes both top-tier national brands and highly-rated local experts.
