Solar Panels in Louisiana: Cost, Companies & Installation Tips

If you are tired of your large electricity bills, occasional power outages, or if you want to contribute to saving the planet by switching to renewable energy, installing solar panels on your property is the perfect choice for you. This process can also be a bit confusing, so continue reading to find out everything you need to know about solar panels in Louisiana.

Solar System Installation Costs In Louisiana


The first question many potential customers ask is the price of installing solar panels. The answer largely depends on several factors.

The Material Of Solar Panels

There are two main options used in the production of photovoltaic panels nowadays – monocrystalline and polycrystalline solar panels. They are both made out of silicon, but they differ in how the crystals are distributed in the cells of the solar panels.

Monocrystalline solar panels have one crystal per cell, and in polycrystalline panels, several crystals are molded and put into one cell. You can see the difference just by looking at them – blue panels are polycrystalline, and the black ones are monocrystalline.

Apart from the aesthetics, you should know that monocrystalline panels are slightly more effective and expensive. If you decide to install them, you should be ready to pay a little more, but your payback period will be shorter too.

Size Of The Property

The next factor that affects the total price of installation of the solar panels is the size of your property. Naturally, the larger the area you want to cover with photovoltaic panels the more expensive it is. However, keep in mind that most manufacturers and companies offer a lower price per watt for larger systems – kind of like wholesale.

Residential Vs. Commercial

Finally, the price can be different whether you choose to install a residential or a commercial solar system. The two main differences between the two are size and efficiency. Commercial panels are slightly larger and they are a bit more efficient than the residential ones (by around 2-3%).

This makes them more expensive as well. It’s good to consider commercial solar panels if your property is very large because your profit will be higher, but if you plan to cover a smaller area, you will be just fine with the residential system.

In the table below you will see the average price that you can expect to pay considering the area individual sizes of solar systems cover.

System size Area it covers System cost before ITC
1 kW 90 sq. ft. $3060
2 kW 180 sq. ft. $6120
3 kW 270 sq. ft. $9180
4 kW 360 sq. ft. $12240
5 kW 450 sq. ft. $15300
6 kW 540 sq. ft. $18360
7 kW 630 sq. ft. $21420
8 kW 720 sq. ft. $24480
9 kW 810 sq. ft. $27540
10 kW 900 sq. ft. $30600

Keep in mind that this is the raw price, without any subtractions. Keep reading to find out if you qualify for any of the incentives, tax credits, or rebates the state of Louisiana may offer.

Incentives, Tax Credits & Rebates For Solar Panels In Louisiana

Louisiana had one of the best programs and financial options for solar energy until a few years ago. Most of them are not available anymore, but there are still several incentives that you can take advantage of.

Investment Tax Credit (ITC)

Investment Tax Credit is an incentive implemented by the U.S. government in 2006. It applies to every state, including Louisiana, and it can reduce the total cost of your new solar system by 30%. The ITC can be used both for residential and commercial systems. Keep in mind that it drops to 26% in 2033, and the systems that begin installation after 2025 will not be eligible anymore.

solar Tax Credits

The ITC is not a rebate – you don’t get the money right away. It is rather a reduction of the taxes you would normally pay the government in the amount of 30% of the total cost of your solar system. To be eligible, you need to be a property owner and the owner of the solar system – renters do not qualify for this perk.

Here is the table with the prices after a 30% ITC is applied.

System size Area it covers System cost after ITC
1 kW 90 sq. ft. $2,265
2 kW 180 sq. ft. $4,488
3 kW 270 sq. ft. $6,672
4 kW 360 sq. ft. $8,856
5 kW 450 sq. ft. $11,100
6 kW 540 sq. ft. $13,332
7 kW 630 sq. ft. $15,564
8 kW 720 sq. ft. $17,776
9 kW 810 sq. ft. $19,998
10 kW 900 sq. ft. $22,220

Net Metering

Net metering is a great way to not only save money but also potentially earn it when using solar panels as your main source of energy. Whenever your solar panels produce more energy than you use, the excess energy is sent to the grid, and you are paid for it.

This usually happens during the summer when your solar panels generate more energy than you need for your electricity consumption, especially when you are not home for extended periods.

Home Energy Loan Program (HELP)

Louisiana Department of Natural Resources offers a five-year loan for a solar system that costs up to $12,000. They pay for half of it at 2% interest, which is lower than what you can get on the market. The other half is paid by another lending institution of your choice at their interest rate.

Property Tax Exemption

Installing solar panels on your property increases its overall value. Normally, you would have to pay taxes, but the state of Louisiana offers property tax exemption, meaning that you don’t have to pay taxes for your increased home value. If you decide to sell your house, it can be up to $ 10,000 more than those without a solar system.


Finally, don’t forget about all of the money you will save over the years your solar panels produce electricity for you. The average monthly electric bill in Louisiana is around $112. With the typical lifespan of a solar system of 25 years, you can save more than 30000$!

What To Look For When Installing Solar Panels In Louisiana


One of the most important things that can predict the efficiency of a solar system is the climate. Luckily, Louisiana is very hot, with mild and short winters, giving it plenty of sunny days to power your solar panels properly.

This state averages 216 sunny days per year with an average temperature of 68.15 degrees Fahrenheit. It has around five peak hours per day, meaning that there are five hours every day when your solar panels get enough sunlight to produce 1000 watts of energy per square meter. Anything over four hours is a good amount for the efficiency of a solar system.

When it comes to the position your solar panels should be put at, it depends on the exact city where you live. However, here are the approximate numbers. If your solar panels are fixed throughout the whole year, they should be at around 27 degrees.

If you want to change the position of your solar panels two times a year they should be at around six degrees during summer and at around 45 degrees during winter.

When the position of solar panels is changed four times a year, they should be at approximately 27 degrees in spring, 50 degrees in summer, 3 degrees in autumn, and again 27 degrees in winter. However, you shouldn’t worry too much about the angle and the direction at the beginning as your contractor will do that.
