Since the founding of our monastery in 1878, our goal has been to become self-sustaining, as Saint Benedict envisioned for his monks 1,500 years ago. Consistent with this, over the years our monastery has undertaken water management by building three lakes that provide water for our monastery and the neighboring city; hog production; gardening; a vineyard; dairy production; a cattle farm; and numerous other ventures. Some of these sustainability efforts have been successful, while others have ceased operation. In recent years, we have switched to LED lighting, replaced our inefficient high pressure steam boilers with smaller efficient units for our heating needs, timber management of our land, engaged in an ongoing recycling program, and now will use solar power for our electrical needs. We researched wind management and solar power but found that our location and availability of land with continuous sunlight would allow solar to be the most viable option. To that end, we began exploring solar power more diligently in the past two years by forming a Solar Committee of people knowledgable in technology, electricity, engineering, land management, and finance. Under our Procurator's leadership, we also explored solar power projects already in operation nationwide to gauge the long-term value and return on investment in those projects. It has only been in recent months that government incentives and an advancement in technology have allowed us a payback that makes this project ecologically sound and cost-productive for our monastery.
Subiaco's project is privately funded at $2.7 million. This project also hopes to avail itself of rebates, federal tax credits, and incentives available in the Inflation Reduction Act. Over 30 years, the estimated electrical bill savings will reach $5,927,591, with a payback period of 9.8 years.
The facility will be located on 6.45 acres of abbey land northwest of our Subiaco Academy football field. This would be west of Highway 197 at the coordinates 35°18'10.5"N 93°38'10.7"W. We explored various areas of our total abbey land, and this proved to be the more viable and cost-effective.
This Solar Tracking Array is projected to produce an annual energy output of 2,247,925 kilowatt-hours (kWh). Thus, 94.8% of the electrical needs of Subiaco will be provided by the new solar facility.
2,784 modules at 450 watt per module.
A tracking system follows the sun's arc through the sky each day and maximizes energy production in all seasons. Tracking arrays are more complex, but tracking systems actually cost less than fixed due to the reduced amount of panels needed. Tracking arrays also have a smaller footprint thus requiring less land. This adds a bit of cost and complexity to the array but the 15% of added energy production increases the systems cash flow over time and brings more savings to Subiaco.
Our US-made solar modules have a 30-year warranty and will continue to produce power after this warranty expires. We model system financials in line with this 30-year warranty but expect these systems to continue to be productive long into the future. At some point, the original solar modules will degrade far enough to be replaced by the newest and most efficient modules on the market at that time – reusing the racking and electrical infrastructure put in place for the original installation. This continues to bring lower electrical costs for Subiaco far into the future with less capital input as the system ages.
Solar modules are tested to hail resistance as part of their UL listing. Modern modules are very resistant to hail but at some point the tempered glass on the front of the module can shatter due to impact from very large hail stones. Once shattered this module needs to be replaced with a module of similar size and electrical characteristics. All entities need to carry current insurance on their solar powerplants and then this insurance is used to replace the broken modules in an array. Subiaco has included the estimated insurance cost in our financial models for the project since it will be an ongoing cost for the client.
Subiaco Academy is a mission of Subiaco Abbey. Our Academy is an internationally famous college-prep day and boarding school for boys in grades 7-12. Our Academy has invested heavily in STEAM (Science, Technology, Engineering, Arts, Mathematics) through a renovated Alumni Hall school building and dedicated staff to mentor and form our students in state-of-the-art facilities and classes. Partnering with Entegrity, our new Solar Power facility will allow our students to have hands-on learning with cutting-edge technology rarely afforded to high school students. Our abbey also hopes to partner with Solar International, a leading solar training and renewable energy education organization, to allow our students and community an opportunity to interact with our solar facility and learn about renewable technology in real-time.
Hundreds of monasteries and religious communities worldwide have successfully invested in renewable energy over the past twenty years as part of our care of creation. Some examples from monasteries in North America that undertook solar projects include:
Subiaco contacted several companies to explore the options for partnering in this endeavor. Entegrity stood out because they were a firm with over 350 projects completed and over 45 years of experience in this field of sustainable energy. After contacting the leadership of previous projects completed by Entegrity, Abbot Elijah and the Monastic Chapter made the final decision and noted, "From day one in a meeting with Elston and Flint, we could easily see how this was truly a firm of integrity. We monks are cautious in doing business only with those we know will maintain our values and understand the mission to which God has entrusted us. We are proud to partner with Entegrity in this truly transformational project for our Abbey, Academy, County, and State."

Laudato Si’ (“Praise be to you”) is the second encyclical of Pope Francis. The encyclical has the subtitle On Care for Our Common Home and was published in 2015, addressed to “every person living on this planet.” (LS 3) Pope Francis describes the encyclical as “a new dialogue about how we are shaping the future of our planet,” calling upon the Church and the world to acknowledge the urgency of our environmental challenges and to join him in embarking on a new journey to integral ecology. You can read that encyclical by clicking HERE.
Laudate Deum (“Praise God”) is the third encyclical of Pope Francis and is meant to address what Francis in the document calls the “global social issue” of climate change. The pope said that in the eight years since Laudato Si’ was published, “our responses have not been adequate” to address ongoing ecological concerns. You can read that encyclical by clicking HERE.
