How to Choose Your Best Solar Company in 2025
Getting solar is an important upgrade you can make to your home. In 2025, it’s a way to reduce your electricity bill and a step toward energy independence and a greener future. With hundreds of solar companies competing for your business, how do you pick the right one? The company you work with is just as important as the panels on your roof.
7 Key Factors to Choose the Right Solar Company
You need to do some homework to find a trustworthy and skilled solar company. Here are seven key areas to look into before you sign any contract.
1. Experience and Reputation
A company that has been around for a long time is usually stable and trustworthy. Find a solar company that has been around for at least five years. Read what other people have said about them on Google, Yelp, the Better Business Bureau (BBB), and other places. Read the comments as well as the stars to see how the company deals with problems. Also, find out about the skills of their team, such as whether they have any North American Board of Certified Energy Practitioners (NABCEP) certifications.
2. Equipment and Technology
How well and how long your system works depend on the quality of the parts that make it up. There are three main parts to your solar system: panels, controllers, and batteries. These days, batteries can do a lot more than just provide extra power. When you look at them, try to find systems that can be expanded to meet your needs in the future (for example, from 10kWh to 80kWh), that can power big machines, and that have strong safety features like fire suppression and IP67-rated flood resistance. Smart energy control in the best systems can also help you save money on your bills. And a warranty that lasts a long time, like 15 years, is a good sign that the product is good.
3. Warranties and Protection
Warranties are your safety net for this long-term investment. A good solar company will offer a few different types of warranties:
- Workmanship Warranty: This covers any problems from the installation itself, like roof leaks or loose wiring. A 10-year warranty is standard, but 25 years is even better.
- Equipment warranty: This covers the parts like panels and inverters, against defects. Most top-tier panels come with a 25-year warranty.
- Performance Guarantee: This guarantees your panels will produce a certain amount of electricity over time, usually promising they won’t drop below 85-90% of their rated output after 25 years.
4. Licensing and Insurance
This is a must-have. Any solar company you consider must have the proper licenses for your state and carry full liability and workers' compensation insurance. Ask to see proof of these documents. Without them, you could be held responsible for any accidents on your property during the installation.
5. Financing and Purchase Options
Solar is a big purchase, and most companies offer several payment options. A cash purchase offers the best return on your money. A solar loan allows you to own the system and still be able to get tax credits. With a solar lease or PPA, you pay a fixed monthly rate to use the system, but you don't own it. Read the fine print carefully to see the terms and interest rates.
6. The Quoting and Sales Process
The first meeting tells you a lot. A trustworthy solar company will do a full review of your roof and energy use before giving you a quote. Be careful of high-pressure sales tactics. Always get at least three quotes from different companies to compare costs, equipment, and savings. The proposal should be detailed and clear, showing all the costs and explaining the financial numbers.
7. Customer Service and Support
Your relationship with the solar company doesn't end after the installation is done. A great company will have a customer service team that is quick to respond and helpful. Ask about their support and maintenance services after the system is installed.

National solar companies are known for being available in many areas and having standard procedures. Here are five of the top names to consider in 2025, each with a unique strength.

Questions People Ask
Q1. Are small solar companies better than big national ones?
The best pick is different for each person based on their needs. There are usually set ways to do things and ways to pay for big national companies. Companies in your area may be able to give you better service and know more about the rules in your area. You should get prices from both kinds. You can then weigh the pros and cons for yourself.
Q2: How can I find the best solar company near me?
To begin with, type "solar company near me" into a search engine. Next, look at their scores on review sites. Another great idea is to ask your friends for suggestions. Another safe choice is to use a network of approved installers. Look for a company that has a list of approved local professionals who can put you in touch with installers who have already been checked for quality.
Q3. Which of the best solar companies is best for my home?
What you need is what makes a company the "best." A business that guarantees production is a good choice if you want to be sure that your system will produce a certain amount of power. A company like EcoFlow is the best choice for people who want a strong battery backup for their whole house.
Q4. How do I choose a solar company without making common mistakes?
People most often make the mistake of only looking at prices. A low price usually means that the equipment or warranty isn't very good, which can mean that you'll have to pay a lot for repairs later on. Long-term value is a better way to decide what to do. Even if they charge a little more up front, a good company with good tools will save you more money in the long run.
