UWS Kingswood Solar Project

Solar Project at Kingswood Campus

Did you know that over 200 solar panels at Kingswood generate almost 7% of the electricity requirements for the Kingswood campus?

The Kingswood Project has been in operation for the last 3 years. Solar power generation capacity for the roof mounted UWS Kingswood Campus project is approximately 36kW per day. The estimated annual generation is 51MWh.

The above Solar Panel Generation Display Unit is installed in the main foyer of Building K on Kingswood campus and displays the following:

  • current power produced
  • energy produced today
  • total energy produced
  • carbon dioxide (CO2) reductions in kilograms

The Solar Panel Generation Display explained

The 'Current Power' being generated at the time is measured in kilowatts (kW). When the power generated is 25kW (or 2500W), it is sufficient to power approximately 275 computers in the campus.

The 'Energy Today' is energy generated each day and is also measured in kilowatt hours (kWh). The daily average electricity generated by the solar system is equal to 140kWh. This daily solar energy produced is sufficient to meet the energy requirements of nine suburban houses for the day.

The 'Total Energy' is the total amount of electricity that has been generated since the panels started functioning on 15 April 2008. The annual estimated energy offset from the electricity grid is 50,920kWh (or 50.9MWh). This is equivalent to 6.6% of the UWS Kingswood Campus’ annual energy consumption.

The 'CO2 Reduction' is the total amount of carbon dioxide that has been reduced since the panels started functioning on 15 April 2008. The average solar system daily output saves enough CO2 for you to drive emission free from UWS Kingswood to Brisbane in a Toyota Prius Hybrid 5 seater vehicle (1395km). Similarly the annual average CO2 savings are enough for you to drive emission free more than twelve times around the world (509,210km).

What is a Watt or a Kilowatt?

Each of the 216 photovoltaic panels at Kingswood can generate up to 156 watts of electricity at a time. A single 165 watt panel can produce that amount of power when optimum conditions apply. The average house uses about 18 kilowatt hours of electricity per day.

Other Solar Projects

Solar Panels on Hawkesbury.JPGThere are other solar panels projects located on Hawkesbury Campus, as well as on the UWS Hawkesbury Riverfarm.

The solar power generation capacity for the ground mounted on Hawkesbury Campus is 98kW and estimated annual consumption is 132MWh. This is the largest ground mounted solar project in any tertiary institute in Australia. The Hawkesbury Campus project in operation from June 2011 and feeds to early it collects back into the energy grid.
