Benefits of Solar Energy

Solar energy offers multiple advantages. Here are some highlights.

  • Better energy independence: Solar energy can keep your home functioning through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with optional battery backup.
  • Lowered energy bills: You can skip the expensive cost of grid-tied power by creating some electricity right where you use it.
  • Reduced carbon footprint: The sun is a highly abundant clean energy source, meaning you can minimize or conquer your home's dependence on fossil fuels.

How To Choose the Best Solar Company in Brentwood

The cost and efficacy of solar panels often rely on which company mounted them. Consider all of these aspects in your company search.

Licensing and Training

Tennessee requires any solar energy project valued at $25,000 or higher to be overseen by a licensed "prime contractor." The prime contractor is responsible for hiring licensed subcontractors as the job requires. Even if a project doesn't cross the $25,000 value threshold, you will still need a master electrician or electrical journeyman to pull permits. You should also visit a company's website to learn about its private accreditations. 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 Brentwood

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. 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.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can improve your solar system's performance. Not every solar company provides these extras, so look for a company that installs them if it's essential for you.

You can expect to pay about $17,900 on average for a five-kilowatt solar energy system in Brentwood. Check the table in this section to get an idea of what amount Brentwood solar companies might quote for your specific system.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,143
Solar Polycrystalline$891
Solar Battery$731
Solar Home EV Charger$2,742

Financing Solar Energy in Brentwood

Choosing the correct financing solution will influence your overall solar system cost and potential savings. Common payment options include cash payments, loans, leases, and power purchase agreements. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand 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. Much like a home or auto 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) permits you to pay a monthly rate based only on the energy you use, like an electric bill. We typically don’t recommend these two options because you won't own the solar system and are disqualified from using solar incentives. Look for providers that offer two or more payment plans to find the right fit for your financial needs.

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

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

Frequently Asked Questions About Solar in Brentwood

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

On average, Brentwood homeowners spend around $1,502 per year on energy bills. Once you repay your solar array, you could reduce your costs by $482.98 for every kilowatt you produce.

How prevalent is solar energy in Brentwood?

Yes, solar energy is reaching new heights in Brentwood. Some homes already generate solar power on-site or through utility grids, and they're backed by a state solar economy with 4194 job opportunities and counting.

Should I anticipate a property value increase after going solar?

Yes, new solar systems mean higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could increase your home's value by $12,000.

What can I do to predict my home's solar potential?

One common way to find your home's solar viability is by using PVWatts. This free, powerful tool considers tree cover, system size, local weather and topography, and panel efficiency to determine how much electricity your array could generate. However, it's not a substitute for consulting with a solar expert, who can build a full estimate with the most updated data.

How long does the photovoltaic installation process last?

Your solar job's duration will depend on its complexity and size, as well as Brentwood's permit and inspection procedures. It could take two weeks to a few months on average.

How do I care for my new solar system?

To preserve your solar system's efficiency, inspections and cleanings every six months are usually adequate. In dusty or dry seasons, your panels might need cleanings every one to two months. Your contractor can recommend a maintenance schedule. Its team could also tackle the cleaning for you.

How does "net metering" work, and do I need to participate?

Net metering is a system that credits solar homeowners for any excess electricity they generate and feed back to the grid.

Some states or power companies require you to participate in net metering when installing your solar system, while others give you a choice. Either way, once you sign up, you'll earn a check or bill credit for your excess generation at a wholesale or retail rate.

Should I get quotes from multiple Brentwood solar companies?

Yes, we suggest obtaining free solar quotes from three to five companies. You should thoroughly read each quote and compare financing options, prework scope and costs, warranty details, equipment costs and labor fees. Ensure each quote includes an itemized financial plan and includes your projected payback period.
