Solar System Installation Costs in Houston


Let’s start with the most important thing – the initial investment that you have to make in order to go solar. The good news is, Texas is one of the cheaper states in the USA when it comes to this type of renewable energy. The price per watt ranges from $2.60 to $2.80 in 2023.

The average price that you can expect to pay per watt of solar energy in Houston is $2.70. Depending on the size of the property you want to cover with solar panels, you can expect to pay anywhere between $2700 to more than $20,000.


Here is the table that will help you determine how large your solar system should be and what price you will have to pay for it (and that is before the federal tax credit reduction).

Size Area it covers Cost
1 kW 90 sq. ft. $2,700
2 kW 180 sq. ft. $5,400
3 kW 270 sq. ft. $8,100
4 kW 360 sq. ft. $10,800
5 kW 450 sq. ft. $13,500
6 kW 540 sq. ft. $16,200
7 kW 630 sq. ft. $18,900
8 kW 720 sq. ft. $21,600
9 kW 810 sq. ft. $24,300
10 kW 900 sq. ft. $27,000

The table shows what you can expect to pay with the average price. However, as with anything you buy in large quantities, the more area you want to cover, the less you pay per watt. This depends on the company that installs the solar panels so check beforehand if there is any discount for larger systems.

Installing solar panels is a huge investment, but as with any other investment, it’s important to know the benefits it will bring you. The one great thing about this particular investment is that it almost certainly pays off.

Apart from doing your part in saving the planet, you can expect to save a lot of money. The average yearly bill for a Houston home is around $1,900. The average lifespan of a solar panel is 25 years. This means that you will be able to save around $47,000 during the time you get your electricity from the sun!

Incentives, Tax Credits, And Rebates For Solar Panels in Houston

Wherever you live in the USA, you are eligible for ITC – Federal Solar Investment Tax Credit. This is the biggest benefit that you can take advantage of when installing a solar system. It takes 30% off of the total cost of the installation process and material.


You should try to hurry up and go solar as soon as possible because this amount drops to 26% in 2033. This perk can save you thousands of dollars! Here is the table that compares the prices before and after the ITC.

Average solar panel cost in New Jersey (after 30% tax credit)

Size Area it covers Cost
1 kW 90 sq. ft. $1,890
2 kW 180 sq. ft. $3,780
3 kW 270 sq. ft. $5,670
4 kW 360 sq. ft. $7,560
5 kW 450 sq. ft. $9,450
6 kW 540 sq. ft. $11,340
7 kW 630 sq. ft. $13,230
8 kW 720 sq. ft. $15,120
9 kW 810 sq. ft. $17,010
10 kW 900 sq. ft. $18,900

As you can see, the reduction of the cost is far from negligible, for any size of the system you choose.

The next incentive is the increase in property value. Your home is worth 3 to 4 percent more if it is powered by solar panels. In addition, homes with installed solar systems sell up to 20% faster than those without them.

Even better, you don’t have to worry about higher taxes! Texas offers Solar System Property Tax Exemption, which means that even though the value of your property increases, your taxes stay the same.

While Texas doesn’t have a net metering program per se, there is the Clean Energy Credit program. Houston is a sunny city, so it is very likely that your solar system will produce more power than you are able to use.

In this case, the excess power is sent back to the grid and you will earn credits. When you don’t produce enough energy, you will be able to take it from the grid and pay for it according to the standard electricity rate.

When you take into account all of the incentives and benefits that you can use, the total cost of your solar system can drop by thousands and thousands of dollars. Once you have the system installed, you will be saving money constantly.

What To Look For When Installing Solar Panels in Houston


The climate in Houston is optimal for the efficiency of solar panels. The average number of sunny days is 204, and there are not a lot of days when the clouds are blocking the sun entirely.

Solar panels are most efficient when the temperature is around 77 degrees, and Houston meets this criterium perfectly – its average temperature is around this number for seven months of the year. This means that you will not have to worry if your solar panels will produce enough energy for your home.

Another thing to be careful of when installing solar panels is the number of peak sun hours your system receives. This means that your system will produce at least 1000 watts hourly per around 10 ft. of solar panels.

The optimal number of peak hours per day is 4. If your system is fixed, the number of peak hours Houston gets is almost 5! This number is even higher if you decide to use 1-axis or 2-axis tilt solar panels.

Finally, the solar system needs to be positioned properly so it can produce energy at the highest possible efficiency. You have three options – the solar panels can be fixed throughout the whole year, or you can change their direction multiple times per year.

If you decide to have your solar panels fixed, they should be tilted according to the latitude of the city. Houston’s latitude is 29.7 degrees, so your solar panels should be positioned at that angle, facing south.

If you decide to change the position twice a year, they should be at 14.7 degrees in summer and 44.7 in winter. If you want to alter the position four times a year, they should be at 26.8 degrees in the spring and autumn months.
