What is the performance of your solar panel dependent on?
The first factor influencing how much electrical energy you will generate is the size (otherwise known as rated power) of your solar panel. A larger panel ( more watts ) will produce more electrical energy (just as a bigger car engine has more grunt).But if we move past the obvious impact of size, the amount of energy your solar cells produce depends on how much fuel they are fed (just as the amount of energy a car engine will produce depends on how much petrol you pump into it via your foot on the throttle). In the case of solar cells, their fuel is the sun.
The amount of sun your solar cells are exposed to (and hence how much energy they will generate) depends upon:
- The of your installation (which you always try to optimise but depends on the situation)
- Whether there are shadows cast over your panel (due to trees, buildings etc)
- The number of daylight hours (governed by where you are located in Australia)
- The intensity of the sunlight (governed by where you are located in Australia )
- The number of hours of full sun vs cloudy days (governed by the weather)
If we exclude the first two factors, which you have a degree of control over, your location in Australia is the primary variable dictating how much energy your panel will produce. Hence, say a 100 watt system in Melbourne will typically not produce as much electrical energy over the year as the same system in Alice Springs.
