Why do the graphs on the live data feed seem to flicker from time to time?

Why do the graphs on the live data feed seem to flicker from time to time?

The flickering occurs when the display is updated as new data comes in.

Can information on PV electricity production be gained from other sources?

Can information on PV electricity production be gained from other sources?

Yes, inverters can monitor the incoming DC and outgoing AC power and can feed this information to loggers that record the PV electricity production. Inverter data is collected from UQ PV arrays but is not used in the live data feed displayed on this website.

How are the $ savings calculated?

How are the $ savings calculated?

The $ savings are the savings for year to date (YTD). That is, from the start of each year to the present time. They are calculated by multiplying the amount of electricity produced YTD by the average cost of peak period electricity (7 am to 11 pm) in Queensland.

How are the carbon savings calculated?

How are the carbon savings calculated?

The total electricity produced (kWh) since PV was installed at a site is multiplied by an emission factor (kg/kWh) that applies to grid electricity consumed in Queensland. The Commonwealth Department of Climate Change and Energy produces and updates these emission factors.

What does live feed mean?

What does live feed mean?

The data from the meters is transmitted every minute to the server that generates the live data feed. Due to the time needed to send, receive and process data, the information on the live feed display is less than two minutes “old”.

What is the source of the data used on the live feed display?

What is the source of the data used on the live feed display?

The source of the information is a number of electrical meters that directly monitor the amount of AC power produced by the PV arrays.

Where does the weather data come from?

Where does the weather data come from?

The weather data comes from a number of weather sensors at the UQ St Lucia campus. Eventually, we will be able to display weather data from each of our sites.

Where in the electrical system are the meters located?

Where in the electrical system are the meters located?

Inverters convert the DC electricity from the PV arrays to AC power which is then conducted to distribution boards.  The meters are on the distribution boards and measure the incoming AC power produced by the PV arrays.Electricity is distributed from these boards to end uses such as lighting, and power office equipment.  The right hand thumbnail at the bottom of the St Lucia-Multi-level Car Park page shows a typical single line diagram with meter locations. 

Who developed the Live Data Feed Website?

Who developed the Live Data Feed Website?

This was a collaborative effort involving the UQ Property and Facilities Division (Electrical Engineering, Energy Management and Sustainability Units), the Global Change Institute and the UQ Office of Marketing and Communications;  assisted along the way by UQ ITS and using the services of outside IT consultants.
