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 cut 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 helps ensure that the work is done properly using current best installation practices. South Carolina differentiates between mechanical and general contractors for solar energy work. Licensed mechanical contractors can install or repair any solar PV system rated for between 50 and 600 volts if they have an electrical Certificate of Authorization. Solar thermal installers need a Certificate of Authorization in plumbing and a supervising licensed plumber on their team.
Look at review platforms such as TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to find out what previous customers have to say about local solar providers. Reviews can give you an idea of a company’s reliability and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.
Call three to five solar companies for free, itemized quotes. The quotes should explain all costs and list the solar equipment included. Reviewing multiple quotes helps you find the option that aligns with your budget.
Quality solar installations should have strong workmanship and performance warranties. A workmanship guarantee addresses any installation defects (such as poor alignment, cracks in the panels, or poor wiring), while a performance guarantee ensures a certain level of energy production. Strong warranties show that a company is confident in its work.
Going solar can help lower your electric bills over time. When considering the total price and value of solar panels, be sure to consider these factors.
In Greenville, solar panels cost an average of $3,450 per kilowatt, with an average system size of 8.1 kilowatts. The typical Greenville homeowner spends $19,500 on their solar array after federal tax refunds. An estimate from a local provider will factor in additional information based on your desired system's panel type, required preliminary work, capacity, and size. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. If you don't want to use solar power for your entire home, you can install a solar heating system for your water.
There are many benefits to home solar energy. You can reduce emissions, save money, and raise your property values. With the right storage equipment, solar panels can also provide you with additional energy security and offer some protection from power outages.
It depends on where you live and the kind of panels you plan to use. With the winter months in South Carolina being very mild, you have a wide time window to install your panels, though they won't reach peak performance until summer arrives.
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, which means you can reap the savings and environmental benefits that come from using solar energy without having to completely switch over.
Net metering is a power purchasing policy that allows solar energy system owners to get paid for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.
Absolutely. Solar panels exist independently from the power grid in Greenville and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system without a storage system cannot keep you running through a nighttime outage. 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.
Solar panels can be more efficient than other forms of renewable energy. They have low maintenance costs and today's systems can stand up to the worst conditions.
