A 120-year old private school in Western Australia is expecting to save around $235,000 a year on its energy costs after installing an impressive 512kW of rooftop solar.

Scotch College, a 1,500-student, 50-building facility located in Perth’s western suburbs, has installed 1,280 PV panels across multiple rooftops of the senior, junior/middle and maintenance school areas.

The system, installed by energy services business Verdia, will displace about 26 per cent of the school’s grid electricity use, including from a 50 metre pool, multipurpose library, and a large dormitory big enough to house 170 boarding students.

“It’s cheaper and cleaner than grid power and is a working example to students of a 21st century distributed power system,” said Verdia CEO Paul Peters.

The global appetite for ethanol is growing. Breaking the previous record of 1.2 billion gallons set in 2011, the United States exported 1.4 billion gallons of fuel ethanol in 2017, according to the U.S. Energy Information Administration. The majority of demand came from Brazil, where ethanol exports increased for the fourth consecutive year, reaching 450 million gallons in 2017 and accounting for approximately one-third of all U.S. fuel ethanol exports.

For the school, the cost of the system is expected to pay for itself in just under five years and save the school $4 million in reduced energy costs over the life of the assets.
