( Cronkite News ) – WASHINGTON – For 31 consecutive days final summer season, temperatures in Phoenix hit or topped 110 levels, the longest streak ever. That scorching warmth in Arizona dehydrates crops and evaporates water that the state must preserve.
Creating a shadow is one option to overcome the issue.
By utilizing photo voltaic panels, farmers can concurrently defend their crops, save water and decrease their power payments — and a few are doing that with assist from federal packages designed to this sustainable technique of progress can be inspired.
Photovoltaic panels are positioned over the crops, harnessing the solar’s power whereas offering useful shade.
“Solar arrays … assist shade and assist cut back our water use and enhance our water use effectivity, which is essential in locations like New Mexico and Arizona,” stated Derek Whitelock, supervisory agricultural engineer on the US Department of Agriculture. “The crops do not want as a lot solar as they do right here within the West.”
Three-quarters of Arizona’s water provide goes to agricultural irrigation, in response to the Arizona Department of Water Resources. The Colorado River Basin is in a Tier 1 water scarcity, requiring restrictions for agricultural customers. As the drought continues, farmers are in search of new sustainable strategies of rising.
The University of Arizona, in partnership with the US Department of Agriculture, has created an agrivoltaics analysis website to check ways in which photo voltaic farming can profit Arizona.
“You get vital water financial savings,” stated Greg Barron-Gafford, the UArizona professor main the trouble.
A examine led by Barron-Gafford discovered that when watering daily in an agrivoltaic plot, soil moisture stays 15% greater than in a close-by plot with out photo voltaic panels.
Some crops really produce extra water. Cowpea beans, for instance – also called black-eyed peas – have the next yield when grown within the shade of photo voltaic panels. A full day requires twice as a lot water, it seems.
“Agrivoltaics really helped us get extra seed manufacturing as a result of now we’re offering shade, so they don’t seem to be careworn,” Barron-Gafford stated.

Its small 4.8 kW system produces about 40% of the farm’s whole power wants, with an anticipated discount of 17,000 lbs of carbon per 12 months in comparison with standard energy technology, says Sarah Bendok, founding father of Growing Green, and with many panels, “it may be mainly. energy all on the farm. They have a chilly storage the place they put all their merchandise that they need to retailer, the lights, the loos, most all the things there.
“It’s a fantastic feeling…to do a challenge that may profit the group and the crops and the atmosphere on the whole,” he stated.
A variety of federal packages are meant to advertise sustainable rising practices, particularly along with renewable power methods. The Rural Energy for America Program is sending $63 million to Arizona from 2018 to 2022.
REAP offers loans and grants to farmers who make clear power investments. Funding from the Inflation Reduction Act, signed by President Joe Biden in August 2022, is a significant tax overhaul that features incentives for clear power and local weather mitigation.
Among many different provisions, the IRA provides farmers a 30% tax credit score for putting in photo voltaic panels.
The Gila River Indian Community started putting in photo voltaic panels above the Casa Blanca Canal earlier this 12 months, with $5.65 million in federal funding. Nearly 3,000 toes of the canal can be lined, conserving water by decreasing evaporation – and producing greater than 1.31 megawatts of inexperienced power, in response to the US Department of the Interior.
