How Much Does a 1-Acre Solar Farm Cost: Breaking it Down

You may have seen commercials for solar panels and wondered how much they cost and if they’re worth it. While the cost of solar panels has come down in recent years, the price of a full solar farm is still a bit more than your average home system.

So, how much does a 1-acre solar farm cost?

Keep reading to find out.

What Goes into a Solar Farm?

When it comes to solar farms, size isn’t everything. Although they come in all shapes and sizes, there are some common components that go into every one. So, what goes into a solar farm?

Well, the main component is obviously the solar panels. But there’s more to it than that. You need an inverter to convert the direct current (DC) from the solar panels into alternating current (AC), which is what power grids use.

Furthermore, You also need wiring and mounting hardware to attach the panels to your chosen surface, and a system to track the sun’s movement so that the panels can be adjusted throughout the day.

All of this hardware adds up, and that’s why solar farms vary in price so much. The cost of a 1-acre solar farm can range from $400,000 to $500,000 or more, depending on the size and complexity of the installation.

Solar Panel Costs

Now that you know the basics of solar panel installation, it’s time to look at the cost. How much does a 1-acre solar farm cost, anyway?

Solar panel costs have come down in recent years, making them more affordable for homeowners and businesses. The average cost of a solar panel is around $3-$5 per watt.

So, for a 1-acre solar farm, you would need around 2000 panels. That would total $6000- $10,000 for the solar panels alone.

But that’s not all! You also need to factor in the cost of installation, permits, and labor. The average cost of installation is around $5 per watt, meaning the total cost of installation would be around $10,000, but really depends on your location.

The cost of permits and labor will also depend on the location of your farm, but the average cost for labor is $10 per hour.

Inverter and DC Disconnect Costs

Solar inverters and DC disconnects are two of the most important components of a solar farm. They’re responsible for converting the direct current (DC) output of the solar panels into the alternating current (AC) that’s needed to power homes and businesses.

As you can imagine, these components are critical to the function of a solar farm, and as such, they come with a price tag. So, how much does a solar inverter cost? And how much does a DC disconnect cost?

Well, the average cost for a solar inverter is around $1,500, and the average cost for a DC disconnect is around $500. So, if you’re looking to install a 1-acre solar farm, you can expect to pay around $2,000 for these two components alone.

Cost Considerations for Solar Racking

So, what kind of costs are you looking at when it comes to solar racking? Generally speaking, you can expect the price per watt of mounted solar panels to range anywhere from $2.30 to $5.30 per watt.

That is quite a range, but the actual cost will depend on things like the type of mounting system used and the complexity of installation.

For example, if you are dealing with sloped or hilly terrain, then that usually means additional labor costs to account for the extra effort involved in leveling out the land or constructing a racking system from scratch.

Alternatively, if you are dealing with flat land and already have an existing racking system in place, then the cost will be significantly lower.

Therefore, if you want an accurate estimate of the cost for your 1-acre solar farm project, you should factor in all these considerations and consult with a professional contractor who can provide tailored advice on what type of racking system would best suit your needs.

Electrical and Utility Expenses

You can’t forget about the electrical and utility expenses when you are budgeting for your 1-acre solar farm. Depending on your location, these can vary greatly.

These expenses will include items such as energy monitoring systems, energy storage systems, installers for equipment, and connection fees to the grid.

Another important factor to consider is the price of the solar panels themselves. The price of panels has come down significantly in the past few years, so you should be able to get a good deal.

However, as with any purchase it pays to shop around for competitive prices.

Finally, you also have to factor in the maintenance costs of the solar panels and other equipment over time. Regular maintenance such as panel cleaning and checking for damage due to inclement weather can add up over time.

But with proper maintenance, your solar farm will be producing clean energy for years to come!

Additional Costs to Factor In

There are several additional costs to factor in when calculating the total cost of a 1-acre solar farm. First and foremost are the inverter costs, these systems convert direct current from the solar cells into alternating current that powers homes and businesses.

Depending on the size of your system, you may require multiple inverters, which can increase your costs.

You’ll also need to consider O&M (operations and maintenance) costs. This includes any costs associated with monitoring, inspecting, and repairing your system periodically over its lifetime.

In addition to these costs, you will also need to consider your insurance coverage to protect against losses due to damage or natural disasters.

Finally, you’ll want to factor in battery storage if you want to store excess energy for later use. Batteries can be costly, but they are essential if you want your system to be fully self-reliant and reduce your reliance on external energy sources.


The cost of a 1-acre solar farm ranges from $400,000 to $500,000 per acre. However, this cost could go down if the solar farm is located on land that is already owned by the company. Solar farms can also provide other benefits such as revenue from the sale of electricity and tax credits.
