Homeowner's Guide to Choosing a Solar Company

So, you’ve decided to go solar, and now you’re wondering how to choose the right solar company to install your solar system. You want one that is reliable and affordable, providing top-tier customer service. There are hundreds of solar companies out there, so how do you choose one?

No need to fret, we’ve developed this guide to help you choose the right company to begin your solar journey. 

1. Understand Your Solar Needs

Before reaching out to solar companies, it’s important to know what you need from your system. The right setup for your home depends on several factors, like your energy consumption, roof conditions, and budget.

Check Your Electricity Use

Reviewing your past electricity bills will help you understand your energy usage. The higher your monthly electricity consumption, the larger the solar system you will need. Many solar installers use your annual energy usage to recommend the right number of panels.

Look at System Types

Do you want a grid-tied, hybrid, or off-grid system?

Grid-Tied

A grid-tied, or on-grid system is connected to the utility grid (where normal electricity comes from). 

This system works by the solar panels capturing sunlight, which is converted into energy by the inverter. That energy goes into powering your house first. Any excess energy is sent to the utility grid. This extra energy can earn you energy credits and reduce your electricity bill.

On cloudy days or at night, your home can still pull power from the utility grid like normal.

Hybrid

Hybrid solar systems combine solar with a battery backup while maintaining a connection to the power grid.

Your solar panels generate power, which goes into powering your home first. Any excess energy is then stored in a battery for later use, like at night or when the power goes out. If the battery is fully charged and there's still excess energy, that extra energy is sent to the utility grid. In the event that you run out of solar energy, you can still pull electricity from the grid, like normal.

Off-Grid

Off-grid solar systems are just that: off the grid. These systems have battery backups to store excess energy, but any amount above that is not sent to the utility grid. You also cannot pull electricity from the utility grid if you run out of solar energy. Off-grid systems are the most independent of the systems but can be risky.

Examine Your Roof

A south-facing roof with minimal shading and good structural integrity will generate the most solar energy. If your roof is older or needs repairs, it’s best to fix it before installing solar panels.

2. Research Solar Companies

Not all solar providers offer the same level of quality and service. Some specialize in residential solar installations, while others focus on large-scale commercial projects. A good solar company should have experience, proper certifications, and a solid reputation.

• Certifications: Look for companies with NABCEP (North American Board of Certified Energy Practitioners) certification (the gold standard in the industry).
• Reputation: Read customer reviews on Google, SolarReviews, BestCompany.com, and the Better Business Bureau (BBB) to see what customers have to say about their experience.
• Experience: How many years have they been in business? More experience typically means better service and fewer risks.

3. Compare Solar Equipment and Technology

Not all solar panels and inverters are the same. High-quality equipment can make a big difference in energy efficiency and long-term savings.

Solar panel efficiency varies between models, typically 15 to 22 percent. Higher-efficiency panels generate more electricity per square foot.

Also consider a panel’s temperature coefficient (what temperature it’s most efficient at)— if you live in an area with extreme temperatures, you want to make sure your solar panels can keep up.

Additionally, if you want backup power in case of a power outage or at night, battery storage allows you to store excess energy.

4. Review Pricing

The cost of solar installation depends on factors such as system size, equipment type, and labor costs. While solar prices have declined by more than 70 percent in the past decade, it is still a significant investment.

Comparing different financing options can help you make solar more affordable. 

• A cash purchase provides the best long-term savings but requires a high upfront investment.
• Solar loans allow homeowners to spread payments over time while still benefiting from ownership.
• Leasing or Power Purchase Agreements (PPAs) provide little to no upfront cost but mean that you don’t own the system.

Additionally, initiatives like The Federal Solar Tax Credit allow homeowners to deduct 30 percent of their solar installation costs from their taxes. Some states or counties also offer rebates and net metering policies to reduce costs even further.

5. Assess Warranties

A strong warranty can provide peace of mind and protect you from unexpected repair costs. Solar warranties typically cover three main areas: equipment performance, inverters, and workmanship. Reputable companies should offer good warranties, showing confidence in backing their products and services.

• A panel warranty generally lasts 25 years and guarantees that the panels will maintain a certain level of efficiency over time.
• An inverter warranty typically lasts between 10 and 25 years, covering failures in the component that converts solar energy into usable electricity.
• A workmanship warranty, offered by the installer, covers issues related to the installation process and usually lasts 10 or more years.

6. Get Multiple Quotes

A good rule of thumb is to get at least three quotes before making a decision on any home service. Each proposal should include a total cost breakdown, estimated energy savings, and how long it’ll take before your system “pays for itself.”

Avoid companies that pressure you into signing a contract immediately or provide vague pricing details— this can help you steer clear of potential scams.

7. Evaluate Customer Service and Support

Good customer service is essential when choosing a solar company, as you may need assistance with maintenance, system monitoring, or future upgrades.

For example, calling or emailing with a few questions before signing on can help determine whether they are prompt and helpful. Additionally, reading reviews that mention post-installation service can provide insights into how the company handles customer concerns after the initial installation.

9. Final Steps Before Signing a Contract

Once you have chosen a solar provider, carefully review the contract before signing. Look for clear terms regarding payment, warranties, installation timelines, and cancellation policies.

Final Thoughts

Choosing the right solar company is a big decision, but taking the time to research your options pays off. By focusing on quality, warranties, pricing, and customer support, you can ensure your investment in solar energy delivers long-term benefits.

If you’re ready to start, the first step is to gather multiple quotes from reputable solar providers in your area to compare your options.
