5 Questions You MUST Ask When Choosing a Solar Panel Company
Checking Company Background and Reputation
Looking into a company's background helps ensure you're working with a dependable installer who can meet California's specific solar needs. Since you'll rely on them for warranty and support over the years, doing your homework is a must.
What certifications and licenses does your company have?
Make sure the installer has a valid CSLB license and NABCEP certification. These credentials verify they meet California's legal requirements and have the technical skills needed for solar installations. You can confirm these qualifications on official sites like CSLB and nabcep.org.
How many years have you been in the solar business?
Experience matters. Companies with a long history in the solar industry are more likely to have a deep understanding of local regulations, streamlined processes, and the ability to honor warranties. A solid track record also shows financial stability and familiarity with working alongside local utility providers - important factors when you’re counting on them for support over the next 25-30 years.
Can you share customer reviews or references?
When looking at customer feedback, pay attention to key areas like installation quality, communication, adherence to timelines, post-installation support, and system performance. Consistent patterns in reviews can help you spot strengths or recurring issues.
"Look for reviews on independent platforms like Angi, and ask if you can contact any customers from their list at random for an unbiased reference. This helps ensure the reviews are genuine and not cherry-picked" [1]
Request references for projects similar to yours and check platforms like Angi for impartial opinions. Be cautious of companies unwilling to share references or those with repeated negative reviews about the same problems.
After confirming the company's reputation, the next step is to review their warranties and guarantees to ensure you're covered in the long run.
Understanding Warranties and Guarantees
Solar warranties are an essential part of protecting your investment. They also show how much confidence a company has in the quality of their products and services.
What warranties are included for panels and installation?
Most solar systems come with several types of warranties:
- Product warranties: These cover manufacturing defects and usually last between 10 and 25 years.
- Performance warranties: These guarantee a certain level of energy output, often for up to 25 years.
- Workmanship warranties: These cover installation issues and can range from 1 to 25 years.
Some manufacturers, like Silfab and REC, even offer extended warranties if you use certified installers.
What if the system doesn't meet performance expectations?
It's important to ask about expected energy production levels, how the company verifies underperformance, and what steps they’ll take to resolve issues. This could include repairs or compensation. Be sure to clarify any exclusions or limitations to avoid surprise costs down the line.
Another thing to consider is whether the warranties are transferable. This can make your home more appealing to potential buyers if you decide to sell. For extra peace of mind, check if your homeowner’s insurance covers external damage, like severe weather or accidents, as these are usually not included in standard solar warranties.
Once you’re clear on the warranties and guarantees, you’ll be ready to move on to understanding the installation process for a hassle-free experience.
Details About the Installation Process
Once you've confirmed the company's reliability and warranty coverage, it's time to dive into the installation process. Knowing what to expect can help you avoid unexpected issues.
How long does the installation process take?
The entire process - from assessment and design to permitting, installation, and inspection - usually takes about 4-8 weeks. The actual installation itself is fairly quick, typically lasting 1-3 days. However, delays can happen due to weather, structural challenges, or permit approvals. It's a good idea to request a detailed project timeline that factors in possible setbacks.
Who will install the system at my home?
Find out if the company uses its own team or works with subcontractors. Ask about their certifications, especially if they hold NABCEP credentials, which are a strong indicator of expertise. Also, clarify who your main point of contact will be during the project. A dedicated project manager can make communication much easier and keep everything on track.
Do you take care of permits and inspections?
A reliable solar company should handle all permits, inspections, and make sure everything complies with California's solar regulations. This includes working with local utilities and managing the required paperwork. Be sure to ask about the typical processing times in your area, as these can vary depending on the jurisdiction.
Once you're clear on the installation process, you can move on to exploring system design and equipment options that best match your home's needs.

Questions About System Design and Options
How do you evaluate if my home is suitable for solar?
To determine if your home is a good fit for solar, installers conduct a detailed site evaluation. They look at factors like roof orientation (south-facing roofs are ideal), shading, and the roof's structural condition. Tools like Helioscope help analyze shading, weather patterns, and energy needs to create an effective system design. This process ensures your solar setup will work efficiently and meet your long-term energy requirements.
"The assessment process is critical for system performance. We use advanced modeling software to analyze a year's worth of sun patterns and shade impacts. This helps us guarantee our production estimates with 95% accuracy", explains a certified NABCEP installer from California Solar Systems.
What brands and types of solar panels do you use?
When choosing solar panels, it's important to consider their efficiency and warranty. Here’s a quick breakdown of common panel types:
| Panel Type | Efficiency | Best For | Typical Cost |
|---|---|---|---|
| Monocrystalline | 18-22% | Homes with small roofs | $$ |
| Polycrystalline | 15-17% | Budget-conscious buyers | $ |
| Thin-film | 10-12% | Large commercial installations | $ |
Top manufacturers like SunPower and Tesla offer panels with efficiency ratings over 20%, though these tend to be more expensive. After selecting panels, you might also want to explore adding a battery storage system to complement your setup.
Do you offer battery storage systems?
Battery storage is gaining popularity among homeowners who want backup power and more control over their energy use. Well-known options include Tesla and LG Chem. Key factors to discuss include battery capacity, backup duration, smart monitoring features, and installation specifics.
The cost of a typical battery storage system ranges from $10,000 to $20,000, depending on its features and size.
Payment Plans and Incentives
What payment and financing options are available?
When it comes to solar installations, you have three main financing choices, each catering to different needs:
| Financing Type | Ownership | Monthly Cost |
|---|---|---|
| Solar Loan | You own the system | $150-300/month for a $20,000 system |
| Solar Lease | Company owns system | $100-200/month fixed payment |
| Power Purchase Agreement (PPA) | Company owns system | $0.10-0.15 per kWh used |
Solar loans usually span 10-20 years with competitive interest rates, giving you full ownership of the system and access to tax credits. Leases provide fixed monthly payments with no upfront costs. Meanwhile, PPAs charge based on the energy you use, making them a smart choice for those looking to minimize upfront spending.
Do you help with rebates and tax credits?
Rebates and tax credits can significantly cut your solar costs. The federal Solar Investment Tax Credit (ITC) covers 30% of installation expenses, and in California, you can save even more through programs like:
- The California Solar Initiative (CSI)
- Incentives from utilities like PG&E, SCE, and SDG&E
- Local government programs
By combining the ITC with California-specific rebates, you could save anywhere from $5,000 to $10,000 on an average system. A dependable installer will manage the rebate applications for you and ensure all eligibility criteria are met.
Once you’ve secured financing and incentives, it’s worth looking into the ongoing support offered to keep your system running efficiently after installation.
Support After Installation
After installation, keeping your solar system running smoothly over the long term is just as important as picking the right installer.

FAQs
What license do I need to sell solar in California?
In California, anyone selling solar systems is required to have a Home Improvement Salesperson (HIS) License. This license is issued by the Contractors State License Board (CSLB) and ensures that sales representatives meet the legal standards for selling home improvement products, including solar installations.
While the HIS license is mandatory for sales representatives, the company handling the installation must also hold a valid contractor's license. This combination ensures that both the sales and installation processes comply with state regulations [1].
Homeowners can verify both the salesperson's HIS license and the contractor's license through the CSLB's online database. This is an important step to ensure compliance with California laws and to confirm the company's dedication to ethical practices [2].
Being aware of these licensing requirements helps ensure you're working with qualified professionals when selecting a solar installer.
