Louisiana solar power overview

Although there is room for improvement when it comes to solar policy and incentives in Louisiana, the federal tax credit still makes going solar a smart investment for homeowners. Not to mention, the Pelican State receives some of the highest levels of sun exposure in the United States.

Are solar panels worth it in Louisiana

Solar panels have fallen in price by more than 80% in the last ten years. In 2020 they also remain subsidized by the 26% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.

Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

Louisiana solar incentives & tax credits

Federal solar tax credit

The most significant incentive to install solar panels for homes and businesses is the federal tax credit. Right now, the federal tax credit is equal to 26% of the total installed costs of installing a solar system. At the end of 2020, the amount of the credit will fall to 22%. This means that in order to maximize your savings potential, the best time to go solar in Louisiana is now.

Net metering

Louisiana does not offer traditional full retail net metering. Instead, they have implemented a new “buy-all, sell-all” policy that requires homeowners to purchase all of the electricity their home uses from the utility at the full retail rate. 

The utility then buys all of the energy a homeowner’s solar panels produce at the avoided cost rate, which is substantially lower than the retail rate of electricity.

Property tax exemptions

Louisiana has a property tax exemption for solar panel systems. The policy states that 100% of the assessed value of the solar system is exempt from the homeowner’s property taxes.

Is it better to lease or buy solar panels in Louisiana

You will save most money by buying your solar system rather than leasing it. Read more about the pros and cons of leasing vs buying solar.

How long do solar panels last?

Minimum of 25 years but generally 30 or more

How do solar panels work on a home?

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2020 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.

How do solar panels work?

Grid-tied solar system

Solar panels are mounted on your roof and wired together in groups called solar arrays. The power they generate flows into a solar inverter where the direct current (DC) electricity is converted into alternating current (AC) electricity that can be used by your home or exported to the electric grid.

Off-grid solar system

Off-grid solar power involves meeting all your energy needs from the power of the sun. There’s no utility to fall back on. This means the solar installation needs to power the home not just during the day, when the sun is shining, but after dark as well.

Do solar panels require regular maintenance?

No, but cleaning them can improve power generation if they are dirty.

Will residential solar power system cost fall in Louisiana in 2020?

Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Louisiana will fall during 2020.

Can you buy DIY Solar Panel Kits and install them yourself in Louisiana?

Yes you can! In some cases, you can save $3,000 or more when you install solar yourself, even after receiving the federal tax credit. Despite the potential for savings, data from Lawrence Berkeley Labs shows that only about 3% of homeowners choose DIY solar. 

Reasons for this include:

  • The permitting and inspection process for the utility, the state, and municipalities can be quite complex.
  • The installation work is both dangerous and difficult, with electrical work having to be performed at heights.
  • Often times, solar electricity customers will be charged a premium for DIY installations, which can limit savings.
  • In some states, a solar system needs to be installed by a qualified solar contractor in order to take advantage of incentives. In Louisiana, qualified solar contractors must have a Solar Energy Equipment classification and an electrical work classification for photovoltaic installations over $10,000. Utilities and incentive programs may have additional requirements.

 

SolarReviews does not recommend DIY solar installations unless you have suitable skills. However, for those who do, SolarReviews published a comparison table displaying solar panel kit prices from the top 10 leading solar kit websites in the US.

How much electricity do solar panel systems generate in Louisiana?

What are the pros and cons of installing solar panels in Louisiana?

The biggest advantage of installing solar panels in Louisiana is the federal tax credit. Plus, state law exempts the value of a solar system from being added onto your property taxes.

The disadvantage of installing solar panels in Louisiana is that there is very little in the way of state and utility based incentives. Recent changes to the state’s net metering policy makes the payback period for a solar system in Louisiana significantly longer than it was before. 

However, because of the federal tax credit, now is the best time for Louisiana homeowners to make the switch to solar.
