Located in Keaʻau, on the Big Island of Hawaiʻi, is a Hawaiian language immersion charter school, called Ke Kula ‘o Nāwahīokalani’ōpu’u Iki LPCS, a Lab Public Charter School managed by University of Hawaiʻi (the collaborating university) – Nāwahī for short. The school is comprised of families, teachers asnd staff who have chosen to speak Hawaiian as the first and main language of the home. Nāwahī provides an environment that embraces culturally rooted principles of spirituality, love, knowledge and respect for the environment.
Respecting the Environment
Keeping with these principles, the school engaged local solar experts at ProVision Solar to move toward a sustainable way to generate energy – they chose solar power.
While their system was to be grid-tied, a Tesla battery back up system comprised of 3 Tesla Powerwalls, each with 13.5kWh of energy storage, was also installed.
“With the addition of the batteries, the school can use more solar energy onsite and have backup power in the event that the grid goes down.” states Marco Mangelsodorf, President, ProVision Solar, Inc.
Battery Storage – Makes Good Financial Sense
Having batteries installed on a solar array in Hawaiʻi makes good financial sense because electricity in Hawaiʻi is very expensive. This is due to the fact that much of the energy for the islands are generated from imported fossil fuels. The solar installation for the school will offset 30,000 kWh of electricity purchased from the local utility company. Read article
