How Much Do 1 MW Solar Farms Make Yearly? [Profit Per Acre]
On the average, the solar farm profit per acre is somewhere between 21,250 and 42,500 on an annual basis.
Whenever any entrepreneur wants to start a new business, one of the first questions that they usually ask is how profitable the business is or how much they are likely to make on the average daily, weekly or yearly from the business. This narrative also applies to entrepreneurs who are looking towards starting a solar farm business.
They would want to know how much they are likely going to make monthly and annually from their farm. Megawatts are used to measure the output of a power plant or the amount of electricity required by an entire city. One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts. Gigawatts measure the capacity of large power plants or of many plants.
You are expected to have an idea of the number of solar panels needed to generate 1 MW and 1 MW is equal to one million watts. If you divide this one million watts by 200 watts per panel, we are left with needing 5,000 solar panels to produce one MW of power.
The truth is that there is no one-mold-fits-all when it comes to how much a 1 MW solar farm is expected to make. There are some factors that we are going to look into before giving an estimate of how much an average 1 MW solar farm make yearly and these factors are;
Factors That Determine the Profit Per Acre of a 1 MW Solar Farm?
One cannot conveniently state the amount a 1 MW solar farm is expected to make yearly if you do not know the amount of electricity the solar farm is expected to generate. A 1MW system can generate between 1,300,000.1,600,000kWh per annum. This equates to around 3,500 – 4300 kWh/day on average.
When it comes to setting up a solar farm, location plays a major role which is why feasibility studies and market survey are essential before settling for a location.
Usually, if your solar farm is located in an area that is known to be sunny year in year out, you are sure of generating enough solar energy and, you may not have to struggle to make good money from the business. But if you locate the solar farm in a location that hardly sees sunlight, then you will sure make lower money from your 1 MW solar farm.
Alternate Power Sources in the Area (Competition)
Another important factor that will determine how much a 1 MW solar farm is expected to make yearly is the type of alternate power sources available in the location.
Aside from solar energy which is power generated from the sun, we have Geothermal energy from heat inside the earth, Wind energy, Biomass from plants and Hydropower from flowing water. If residents of the area where you have your solar farm have a cheaper source of power, they would want to price down your power supply.
Land Acquisition and Permitting
One of the first expenses associated with building a solar farm is acquiring suitable land. The cost of land varies significantly depending on factors like location, accessibility, and local regulations. In addition to purchasing the land, you will also need to obtain the necessary permits and approvals, which can add to the overall cost.
- Land acquisition: The cost of land for a solar farm typically ranges from 450,000 to 4,000 per acre, depending on location and other factors.
- Permitting: Obtaining permits for solar farm development may cost between 10,000 and 200,000, depending on the size of the project and local regulations.
Equipment and Installation Costs
The equipment required for a solar farm includes solar panels, mounting structures, inverters, and other electrical components. The cost of this equipment, along with labor and installation expenses, represents a significant portion of the total solar farm investment.
- Solar panels: Solar panel have decreased significantly in recent years, with the average cost per watt now ranging between
Operation and Maintenance
Solar farms require ongoing operation and maintenance (OM) to ensure optimal performance and longevity. OM costs include regular cleaning of solar panels, preventive maintenance of equipment, and monitoring system performance. These expenses typically range from 10,000 to 50,000 per year for a 1 MW solar farm.
Several other factors can influence the overall cost of building a solar farm, including:
- Financing: Depending on the financing method chosen, interest rates and loan terms can impact the total cost of the project.
- Incentives and rebates: Government incentives, tax credits, and rebates can significantly reduce the cost of a solar farm investment. Research and take advantage of any available programs in your area.
- Interconnection: Connecting a solar farm to the grid may require upgrades to the existing infrastructure, which can add to the overall cost.

How many megawatts do we need?
We must understand the amount of renewable energy needed to meet our climate goals. Before 2030, we need to install an additional 1,041,000 megawatts of renewable energy globally to stay on track with the Paris Agreement.
To put that into perspective, an average home in the US consumes about 10.65 megawatt-hours each year. Keep in mind that can vary based on the climate as air conditioning will require more electricity consumption; for example, someone in Florida will use more electricity in August to cool their home than someone in Oregon. According to the 2019 census, there were 120,756,048 households in the US. That would mean that if we ignore climate fluctuations and assume average usage, the US consumes almost 13 quintillion kilowatt-hours each year! With only 12% of total US energy consumption and 20% of electricity generation coming from renewable energy sources, we have a lot of work to do to get to net zero.
Now that we know how much energy we’ll need let’s look at how solar and wind power can make an impact.
Solar Energy
Solar energy is created through the generation of solar power through solar panels. You can read more about solar energy in our renewable energy primer. To give you a brief recap, solar photovoltaic (PV) panels take the energy emitted by the sun and convert it into electricity using semiconductors. In contrast, solar thermal systems use thermal heat from the sun. Concentrated Solar Power (CSP) is a solar thermal system that uses mirrors to FOCUS the sun’s rays to create heat, thus producing electric power.
To generate a megawatt of solar energy, you need a large space such as a huge roof or a field. A megawatt can cover 6 to 8 acres, which is roughly 4.5 to 6 football fields.
It’s important to remember that you aren’t guaranteed a full megawatt of electricity production just because you install enough solar panels to cover 6 football fields. You have other factors to consider, such as the location of the panels. Specifically, how much sunshine the panels receive and the temperature.
The best way to capture solar energy is when the sun is shining directly at the earth. The geographic location of the solar panels and season play a major role. As the time of day and season change, so does the earth’s position in relation to the sun. Thus, a location closer to the equator will have a greater number of optimal days for solar energy production. For example, California will likely have better conditions for solar than Alaska, even though Alaska will have longer sunlight hours than California in the summer. California’s closer proximity to the equator means that there will be more days when the sun is almost directly over the panels, producing more solar energy. There will also be more days in the year to have enough sun to produce solar energy.
As for temperature, all solar panels are tested at “standard test conditions” with temperatures of 77 degrees Fahrenheit. That’s not to say that the panels won’t work in colder or warmer temperatures, but the panels are rated based on those conditions.
Depending on the manufacturer, the range of electricity output for solar panels can vary. This is due to the solar panel’s cells’ ability to absorb solar energy. Three different silicon solar cells are used in solar panels: monocrystalline, polycrystalline (sometimes called multicrystalline), and amorphous. The former being the most expensive and effective, and the latter being the cheapest and least powerful of the three.

Solar power production will vary by type. There’s a difference between solar PV and thermal systems, and there’s also a difference between utility-scale solar and the solar that you’ll find on single-family homes.
Utility-scale solar systems are massive systems that are at least one megawatt. You will only find CSP systems on utility-scale solar because those systems are very large and usually found in very sunny rural or remote areas. Utility-scale solar tends to produce more electricity than smaller systems on single-family homes. This is in part due to location. Utility-scale solar will be placed in the most optimal location for solar, whereas most homeowners have to work within the confines of their existing property lines.
Current state of solar-powered electricity generation
The Solar Energy Industry of America (SEIA) and National Renewable Energy Lab’s PVWatts looked at each state’s average solar PV performance. They averaged it to determine that one megawatt of solar can power 190 homes. If you’re curious to learn how this is calculated, check out SEIA’s website.
If we were to put that into other terms, one megawatt of solar could power over 174 million smartphones – that’s enough power for 59% of the smartphones in the US. That’s also the same as swapping 54,346 incandescent light bulbs for LEDs. That’s almost 5.5 times the number of lights in the Chrysler Building in New York (fun fact: they did a lighting retrofit in 2014 and saved 55% of their electricity costs by switching to LEDs in the building’s spire).
The US’s current solar capacity could power 17.7 million homes! But with over 120 million households in the US, currently, we are falling short.

Erthos, an Arizona-based startup, has developed a new way to install solar power plants directly on the ground, without the need for mounting structures.
“It takes advantage of the heat absorption properties of the earth, offers unbeatable aerodynamics, and is the lowest cost installation method in the world,” the company said in a statement.
Erthos claims that the new method enables the construction of solar plants in half the time and one-third of the land compared to conventional ground-mounted facilities. The new method also uses 70% fewer cables and trenches, and reportedly reduces installation costs by at least 20%.
Daniel Flaningan, head of marketing and product at Erthos, said the project design only requires light civil engineering. The method is also usable in different topographies, with little to no grading. In addition, projects built under this system can withstand “category 4” hurricanes, according to the company.
The company recently signed an agreement with US developer Industrial Sun LLC for a new solar project of more than 100 MW in Texas.
“As it is an area with minimal developable land, the developer could not install such a large project with conventional solar technologies, which usually require between five and six acres of land per megawatt,” said Erthos. “In contrast, Earth Mount Solar PV typically requires less than 2.5 acres per MW, achieving more than double the energy density of typical systems.”
