Sippy Downs, QLD
Education
When the outgoing Principal of Siena Catholic College in Sippy Downs Queensland announced his retirement at the end of 2016, he wanted to be able to leave behind a legacy item – an 80 kW solar system from Planet Ark Power, for the school and its students to benefit for years to come.
Challenge
Siena Catholic College was looking for a way to reduce energy costs, reduce CO2 emissions and provide a more sustainable campus.
With 1,000 students onsite, the project had to be completed within WHS guidelines and accommodate logistical, scheduling and construction restrictions. Planet Ark Power was able to design and implement an integrated, end-to-end solution.
Solution
Planet Ark Power designed a rooftop solar system, consisting of 80 KW of rooftop solar using 308 solar panels and 3 inverters.
Anticipated to generate 120,000 kWh to mitigate against cost of future energy price rises saving an estimated $26,475 in annual energy costs. Estimated annual emission savings of 92 tonnes of carbon – the equivalent 200,000 kms travelled by car in a year.
Results
92 TONNES
CO2e Savings p.a.
Environmental Impact
80.08 kW
SYSTEM CAPACITY
31%
Annual Savings
Reduction in power cost
The Siena College installation has been operating smoothly since its commissioning in late 2016. The system has been a success and operated as a reference point for Planet Ark Power securing additional school sites for its commercial rooftop installations.
We have installed an 80 kW system that meets the complete needs of the College and significantly reduced our $75,000 a year electricity bill.
