Access to Clean Energy: SMA Supplies System Technology to Costa Rica's Largest Solar Power Plant HUACAS, Costa Rica – April 5, 2022 ? In the town of Huacas, Advanced Energy, and local partner HiPower are jointly building Costa Rica's largest PV plant. SMA Solar Technology AG (SMA) is supplying 34 Sunny Highpower PEAK3 solar inverters to the 7.24 MWp project, which is scheduled to be commissioned in April. The Solar Huacas project is a milestone for the Central American country, which offers great potential for solar energy expansion. The solar energy generated will flow into the decentralized power grid of Cooperativa de Electrificación Rural de Guanacaste R.L.. The electrification cooperative aims to make as much renewable energy as possible available to its customers in order to provide clean, reliable electric power supply to residents and businesses in Huacas. "It's great to see Costa Rica embracing renewable energy instead of deforestation, providing residents with widespread access to electric power," said Daniel Rosende, managing director of SMA Latin America. "We are pleased to have been contributing to such important and sustainable projects with our innovative solutions for more than 40 years." Advanced Energy, a Central American company, has been building its facilities and projects with SMA inverters for more than 15 years. "We have consistently found that SMA manufactures the most reliable and powerful inverters on the market," said Alberto Giron, managing director of Advanced Energy Holding. The 7.24 MWp system in Huacas is scheduled to come online in June and will generate about 12,277 MWh annually - equivalent to the consumption of about 3,800 Costa Rican households. The solar system consists of 12,243 Canadian Solar modules and 34 Sunny Highpower PEAK3 150 solar inverters. The PEAK3 system solution combines the advantages of a decentralized system layout with those of the central inverter concept and is designed for easy installation and maximum power generation.
