First-of-its-Form Solar Array in Arkansas to Energy Hospitals


Researchers and laboratories are always advancing the science of medication. The noble explanation for serving to others to heal and really feel higher has developed enormously during the last hundred years. A well being care firm with a number of branches in Arkansas helps differently, nevertheless, and it is serving to the chain of hospitals turn into extra sustainable and self-sufficient down the street.

Unity Health has partnered with Bernhard to replace current gear and set up a variety of Earth Mount photo voltaic panels which can generate energy for its rural hospitals and result in better sustainability.

Bernhard’s “Energy-as-a-Service” program may even enable them to promote their extra electrical energy to the grid for revenue.

“Our engineering folks acknowledge that quite a lot of our gear is fairly dated,” stated Stuart Hill, vice chairman and treasurer of Unity Health. “They introduced this venture, power as a service, as a approach to improve gear that wanted upgrading. The economics of it appeared cheap to us.”

The partnership comes after a decade of working with Bernhard on different initiatives. Hill stated the staff has constructed quite a lot of confidence by increasing operations in Searcy.

The venture impacts 4 Unity Health System hospitals: Newport, Jacksonville and two areas in Searcy. The Newport department will solely obtain LED upgrades as a result of it already makes use of totally different power elements than the opposite three hospitals.

The first section of labor is to make hospitals as environment friendly as doable earlier than worrying about power manufacturing. Another aim is to offer full backup technology at one of many Searcy websites.


The better part in regards to the venture, in keeping with Sam Selig, senior vice chairman of renewable power at Bernhard, stated photo voltaic panels assist offset a few of the prices. The panels are anticipated to final 10-20 years, providing power financial savings all through.

“Bernhard upgraded onsite backup turbines and significant techniques to extend reliability and enhance power effectivity,” Selig stated. “The offsite photo voltaic venture completes the trifecta by considerably lowering utility prices.”

The roughly 10,000 panels might be situated on an off-site property bought by the Morrilton hospital system. The plot of land was chosen as a result of it’s inside Entergy Arkansas territory, and due to Inflation Reduction Act, there are extra bonuses for its development in an “power group” designated by the act. Most of the parcel can be situated in a floodplain and isn’t appropriate for different makes use of.

Most of the annual manufacturing happens within the spring and summer season, with December and January seeing the least quantity of manufacturing. During the months, the corporate expects a capability issue of greater than 28%, which barely exceeds conventional photo voltaic installations, in keeping with Selig.

The whole price of the venture, which can take two and a half years to finish, is estimated at $52 million. The group estimates advantages of $63 million in power financial savings over 20 years.

“We’re excited for the lengthy haul,” Hill stated. “It was a problem right here to start with. But the long term is what we would like. “

Earth Mount arrays started gaining traction round 2019, in keeping with Selig, who has been with the corporate since January 2022. He started working within the trade in 2019 when “all the foundations modified in Arkansas .”

The Morrilton website north of I-40 was first cleared after which grated in order that the whole patch was lined with dust. The panels will then be put in, and the grass might be reseeded to fully encompass the panels within the floor. Selig stated that it installs “like a carpet, like the ground virtually.”

“During the planning course of, a substantial quantity of effort was put into making the location as inconspicuous as doable to all neighboring landowners,” Selig stated.


He stated the Earth Mount array would take up a 3rd of the scale of a conventional array. While that is the primary such array to be put in within the state, Selig believes the development will improve as a result of it “simply makes a lot sense.” According to him, Arkansas is within the prime 15 for photo voltaic radiance on the floor of the earth, or the quantity of photo voltaic power that can be utilized per hectare of land.

“Earth Mount photo voltaic is essentially the most environment friendly set up methodology by way of land use and price,” Selig stated. “Bernhard’s enterprise is effectivity and conservation. If we will set up Earth Mount photo voltaic utilizing 60% much less land than conventional photo voltaic, then the choice might be a no brainer. An additional advantage is that the set up is rather more aesthetically pleasing as properly. “

Bernhard will proceed the array. Through an operation and upkeep contract, Bernhard ensures financial savings for many years to come back, guaranteeing that it produces what it claims. The firm makes use of robots to wash the photo voltaic panels once they get soiled.

“The venture has a 40-year design life, and the photo voltaic panels are assured for 30 years,” Selig stated. “Inverters – the gear that converts DC energy to AC energy – must be changed in about 15 years. We price range 5 cents per Watt for this alternative.”

Bernhard is presently concerned in over 250 hospitals and well being techniques throughout the nation. It not too long ago closed a take care of Adventist Health to handle growing old infrastructure at 25 areas in California, Oregon and Hawaii.

The firm is trying to convey endurance and power independence in healthcare corporations throughout the nation, such because the funding in Unity Health. Guaranteed financial savings over the whole 20-year time period of the venture will assist fund the renovations wanted now.

“Solar appeared like the fitting factor to do,” Hill stated. “And to cut back the carbon footprint.”
