Puerto Rican mining company, Ecologica Carmelo, is turning to solar to supply electricity. While 80 percent of the island’s electricity comes from burning oil, Puerto Rico reportedly receives more sunlight than the California desert. In October, Prairie Gold Inc. completed the installation 1MW of Stion solar modules. Stion modules consist of dual stacked thin-film solar panels.
Prairie Gold installed 6,908 Stion “Simply Better” 145W frameless (STL-145) solar modules on a ground mount for the project. The solar array is expected to generate 1,738 megawatt hours per year. Stion says that this output is about 6 percent more than a similarly sized traditional crystalline silicon array.
Stion’s modules maintain the Salt Mist – Severity 6 IEC certification and are certified for installation in the Commonwealth of Puerto Rico. Prairie Gold selected Stion modules for their increased energy generation, and for their durability and proven performance in marine settings.
Prairie Gold built the solar array for Ecologica Carmelo, which mines sand and aggregates. The mining facility expects to save about $300,000 per year in energy costs.
A nearly 3-day, island-wide blackout that occurred in September underscores how Stion solar modules can offer a more dependable energy source for industrial and commercial companies in Puerto Rico.
Allied Energy Services, a Georgia-based company developed the project before selling it to Prairie Gold which owns it. Prarie Gold is now awaiting commissioning of the system.
“We were excited to team with Prairie Gold Solar when entering the Puerto Rican market because it simply made sense. With the warm climate in the Caribbean and Stion’s industry leading temperature coefficient, Prairie Gold, who owns the system, will realize a much better ROI than they would have with crystalline modules.”
