Farm solar energy opportunities expand in Ohio

As well as being environment-friendly and economical for home and commercial purposes, photovoltaic solar energy has a lot of applications for farms everywhere. The US Department of Agriculture tells us that 36,331 farms use solar energy, making it by far the most common type of renewable energy technology for farming in this country. (Other stats place the number closer to 90%.) In Europe, production of renewable energy from agriculture increased almost sevenfold over only six years recently. Though California uses more renewable energy systems in agriculture than any other US state, the technology is up and running in Ohio, too.


Energize Ohio demostration project (OSU)You may not be aware how Ohio farms currently use PV solar. One farmer uses his new system to decrease grain drying costs. Another has invested in on-farm solar to offset some of the electricity needs at a swine finishing facility. Five years ago, there were 115 installations in the state, and the numbers have been growing swiftly as the word gets out about new advances in solar technology and financial incentive programs.

Tech improvements and market development have cut the price of on-farm solar systems for farmers in Ohio by more than half. Some basic information about prices: a Department of Energy Sun Shot Report points out that the average installed PV solar price for a midsize system (10 kW to 100 kW) has dropped by 6-7% annually since 2000. Average installed cost then: $10 per watt; 2012, $4.62 per watt.

Eric Romich, a field specialist in energy development and leader of OSU Extension’s Energize Ohio signature program, thinks solar offers important benefits to ag operations.

“Farmers have access to open land and often have high electricity demands. Solar energy reduces volatility of future energy costs, has low maintenance costs and positive environmental attributes, and once the initial capital investment is recovered, the energy is free.”

Romich and his Energize Ohio program have put together some amazing resources for both food and livestock farm solar systems in Ohio. They show step-by-step how solar energy can benefit farm operations and the nitty-gritty of farm solar costs. You may be interested in their video series on renewable projects and energy efficiency. One especially useful program (video below) gives an overview of Ohio’s renewable energy policy, net metering, solar PV technology, on-farm solar applications, and a review of Ohio examples.

Currently, Energize Ohio is assembling fact sheets that deal with important topics for farms and similar operations:

  • Basics of on-farm solar energy systems,
  • Estimating the size of a solar energy system,
  • Site assessment for a project, and
  • Financing.

The team has also recently designed and built a Mobile Solar Unit with a 140-watt PV solar panel, charge controller, battery back-up system, 2000-watt inverter, and safety disconnects. Very useful for remote outdoor events, field days, county fairs, and 4-H camp demonstrations, and it offers attendees a ready-made charging station for cell phones and laptops! It fits in the back of a pickup truck and needs only a projector, TV, computer, or microphone. To reserve the Mobile Solar Unit for an event, fill out the application form here.

When greater interest in solar energy picked up with Ohio farmers earlier this year, the OSU extension, government agencies, and industry responded with some educational programs tailored specifically toward farm use. Van Wert/Paulding held an Agronomy Day in February, and Huron County provided a workshop in April. Some of the participants are already putting together farm solar energy systems on their properties.

Most on-farm systems in the state are connected to the existing power grid. Fortunately, Ohio has net-metering policies that allow all utility consumers to generate their own electricity and then offset a portion of what they buy from the grid. Off-grid solar systems, increasing in popularity, may also be useful to the state’s farming community, especially to people in remote locations without access to standard power options.

Romich says he sees a great demand from farmers to improve their operations with this renewable technology.

The USDA’s Rural Energy for America Program (REAP) is available to farmers as well. It offers both loan guarantees and grants and provides a 30% tax credit on the cost of the project. This can mean you’re able to recover the cost of a complete system in as few as four years, with payback starting within five to seven. Contact the program here for eligibility requirements, technology details, and financing information.

Saving the best news on farm solar systems for last: the White House just announced an investment of $68 million in renewable energy and energy efficiency projects in rural areas across the country. Almost 250 of over 500 projects are solar. Some other items that may be helpful to you:
