Sustainable Production and Use of On-Farm Energy

The use of solar energy on the farm can take many forms: heat collectors to dry crops, livestock buildings and greenhouses; water heaters to provide hot water for dairy operations and cleaning; or photovoltaics (panels) to power water pumps, lights and electric fences. Renovating buildings and barns to capture the sun’s energy can provide for cost savings, increased self-reliance and reduced fossil fuel emissions. Financial incentives exist to help offset initial investment.

The following resources will guide you through options for incorporating solar energy into your operation.

Solar Electricity


This series explores generating electricity from the sun, including the considerations you need to make before deciding to invest in a solar electricity system.

Solar Hot Water


This module describes solar hot water systems, which are designed to capture the sun’s energy to heat water.

Solar Energy Training Program


Fact sheets/bulletins on the fundamentals of solar photovoltaic energy systems. 

On-Farm Energy Production - Solar


This solar electricity and solar thermal module provides a basic understanding and how to calculate a simple payback term for the installation of different size systems. Learn about programs that may be available to subsidize your investment.

Integrating Traditional Foods with Aquaponics in the Desert Southwest


Claudio Rodriguez takes you through the basics of aquaponic growing at Arevalos Farm in McNeal, AZ. Project partially funded by Western Sustainable Agriculture Research and Education.

Thirsty Livestock? Use Sun or Wind to Power a Remote Watering System


Are you getting tired of hauling water to livestock in remote pastures? Jonathan Barter will show us the renewable energy powered watering system on his 210 acre livestock farm. This webinar is part of the 2014 Sustainable Farm Energy Webinar Series, partially funded by the Northeast SARE's New York Professional Development Program.

Dreaming of Local Lemons: Solar Energy Virtual Tour


Summit Naturals Organic Farm has a high tunnel and greenhouse, whose active solar heating systems allow them to grow greens throughout the winter and tropical fruits such as oranges, lemons, pineapples and figs. This webinar is part of the New Generation Energy Webinar Series, partially funded by the Northeast SARE's New York Professional Development Program.

Thermal Banking Greenhouses


Steven Schwen uses thermal banking to significantly reduce the energy costs of running a greenhouse for cold-season production.

Developing an Energy Efficient, Solar-Heated Greenhouse in Maryland


This project investigated the effectiveness of energy-efficient greenhouse design and the ability of water-heating solar panels to heat a greenhouse as a propane alternative.
