From $2,500 to $74: Solar Power Transforms a Dairy Farm’s Electricity Bills
A Pennsylvania dairy farmer has dramatically reduced his monthly electricity bill after installing solar panels on his barn roof.
Richard Perkoski, owner of Main Street Milk, cut his bill from $2,500 to just $74 with a 321-panel solar installation costing $284,000. The USDA’s Rural Energy for America Program (REAP) provided a $110,208 grant, helping offset the investment.
Operating a 590-acre farm with 300 cows, Perkoski relies on electricity for milking equipment, vacuum pumps, lighting, heating, and milk-cooling systems. Excess solar generation can also earn utility credits, further reducing electricity costs.
The savings are helping fund farm improvements, with plans to expand the herd and explore electric tractors.
This example highlights how targeted financial incentives can make solar energy more accessible to agricultural businesses, reduce operating expenses, and strengthen rural energy resilience.
