Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Putting solar panels on your roof could reduce your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.
Hiring a licensed solar installer is critical. This ensures that the work is done properly using current best installation practices. In Missouri, cities and counties have the right to issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.
Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers have to say about local solar installers. Reviews can give you an idea of a company’s reliability and customer service. Avoid companies with no reviews or with predominantly negative feedback.
Get free, detailed quotes from 3–5 solar companies. A quote should describe all costs and identify the solar parts included. Comparing several quotes can help you find the option that best fits your budget.
Quality solar installations should have strong workmanship and performance warranties. A workmanship warranty covers any installation defects (such as poor wiring, poor alignment, or cracks in the panels), while a performance guarantee ensures a certain level of energy production. Strong guarantees show that a company is confident in its work.
Solar is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
The average St. Peters homeowner will spend around $17,066 on a home solar system after federal tax refunds. Solar arrays in St. Peters cost approximately $3,370 per kilowatt, with the average residential solar system being 7.2 kilowatts. An estimate from a local solar provider will include costs for permit fees, preliminary work, and labor, and will account for your system's capacity, panel type, and size. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) system can be used to power any household appliance or system that uses electricity. In the smallest case, you can use a solar water heater.
With home solar energy, you can save money on your energy bill, lower your property's emissions, and be better prepared if there's an outage to the local grid.
It depends on where you live and the kind of panels you plan to use. Since there's a moderate amount of snowfall in St. Peters, your best time to get solar is in the spring and fall.
Yes, you can use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings of solar energy without having to completely switch over.
Your recommended maintenance will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel four times a year. Your solar contractor might offer comprehensive plans where they'll do the maintenance on your behalf.
Of course. Solar panels are independent of the St. Peters grid and will continue to generate power even if the grid is having problems. Bear in mind, however, that a solar system won't take you through a nighttime outage if you don't have a storage system. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.
