St Paul’s College in Walla Walla is set to lower its power bill and its carbon footprint after installing 360 solar panels.
The school has placed solar panels on top of the gym, chapel and Jacob House – one of the original boarding houses now used as classrooms.
The project cost more than $90,000 and was funded by the school.
It is expected the system will generate 20 to 25 per cent of the school's electricity needs.
Business manager John Clarke said he expected the panels to pay for themselves in five or six years.
“We started investigating the prospect last year,” he said.
“Electricity is a major cost and the price of solar panels has dropped in recent years.
“It will help us reduce expenses and savings made will be in invested in other areas.”
