Benefits of Solar Energy

Solar energy provides several advantages that will enhance your home for years to come.

  • Lowered energy bills: With solar panels, you create power without paying the tacked-on costs of grid-tied power. You can eliminate your bills completely if you go off-grid.
  • Better energy independence: Adding a solar battery lets you have reliable energy during grid outages and storms.
  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.

How To Choose the Best Solar Company in Columbia

The more thorough your provider search is, the better your solar panels will ultimately perform. Consider all of these criteria in your business search.

Licensing and Training

South Carolina differentiates between mechanical and general contractors for solar energy work. A licensed mechanical contractor can install or repair any solar PV system rated for between 50 and 600 volts if they have an electrical Certificate of Authorization. If a company installs solar thermal systems, they need a Certificate of Authorization in plumbing and a supervising licensed plumber on their team. You should also visit a company's website to learn about its private certifications. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, awarded by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Columbia

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

If you'd like to charge an electric vehicle (EV) or use your solar power in inclement weather, you can pay extra for accessories. By choosing the right components, you can make your panel array more productive and convenient to use. Not every solar company provides these extras, so look for a contractor that sells them if it's essential for you.

You can plan to spend about $17,250 on average for a five-kilowatt solar energy system in Columbia. Check the table in this section to get an idea of what amount Columbia solar companies might quote for your specific system.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,132
Solar Polycrystalline$883
Solar Battery$724
Solar Home EV Charger$2,716

Financing Solar Energy in Columbia

Choosing the correct financing option will impact your overall solar system cost and possible savings. Common payment options include cash payments, loans, leases, and power purchase agreements. Most solar experts recommend paying cash or using a solar loan. Cash payments require a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Similar to a home or car loan, you'll pay a set monthly rate with as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate determined by the energy you use, similar to an electric bill. We usually don’t recommend these two options because you won't own the system and cannot use solar incentives. Ask each business you're evaluating about the payment plans it offers. A salesperson can help you determine the best option for your pocketbook.

The table below lists the average payback periods for different capacities of solar systems in Columbia.

You can claim a 26% federal tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, utilities and local governments may have their own rebates and financing plans that could reduce your total cost even more.

Frequently Asked Questions About Solar in Columbia

How much money could I save by going solar in Columbia?

Most Columbia homeowners spend about $1,730 on energy each year. Your costs could drop by $1,175.33 for each kilowatt you generate after you pay off a solar array.

How common is solar energy in Columbia?

Yes, solar energy is becoming increasingly popular in Columbia. Some homes already use solar power on-site or through utility grids, and they're backed by a state solar economy with 3307 workers and counting.

Will solar energy systems increase my Columbia home value?

Yes, a solar PV system will increase your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a dark or rainy

Even with Columbia's above-average tree cover, you could still take advantage of solar energy. Your contractor will optimize your system's performance by selecting the proper site for panels, cleaning them regularly, positioning them to capture the most sunlight throughout the year, and installing a battery backup system. This way, you can store solar power and use it as necessary.

What maintenance do my solar panels need, and how often do they need it?

Solar panels don't demand much maintenance to keep working for your home. All you'll need to do is inspect and clean the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to help you in your system's care.

What is the average payback period for Columbia solar panels?

The average payback period for a solar loan in Columbia is 10.3 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

What's the difference between a PPA and a solar lease?

After you sign a power purchase agreement, your solar provider will not charge to install or maintain your new panel array. Instead, you'll pay them only for the electricity you generate. Typically, PPAs last for 10–25 years or until you "buy out" of the contract.

If you choose a lease, you'll make fixed monthly payments.

With both leases and PPAs, you do not own your panels and lose eligibility for most incentives. Further, you'll have to "buy out" or transfer the contract if you sell your home during the term.
