Does Solar system work on a cloudy day?
Yes it does however low light does affect the system efficiency.
Am I able to use solar power during a blackout?
This one is a no. For safety reasons it is mandatory that the system shuts itself down during blackout and resume generation as soon as the grid is online. This protects the technicians who may be working on the disconnected grid.
Can I use solar electricity at night?
Storing solar electricity for night usage means you need to have a battery bank. The cost it against the returns only suits a very few exceptional cases. It is rather viable to use your grid electricity for night usage.
Is solar PV system and solar hot water system the same?
Though both systems work on Suns energy they are relatively different
Solar hot water system uses the thermal energy of the sun in other words it is dependent on the heat of the sun.
Unlike hot water system a Solar PV system works on the photon energy. Solar panels work on the exposure to sunlight instead of the heat.
Which direction the panel need to face?
Australia is located in the southern hemisphere which makes the north facing roof the most optimum for Solar.
I don’t have a north facing roof. Can I still have solar?
Yes, you can definitely have solar. While north remains the most optimum direction, any direction from west to east are suitable for solar, this results in a marginal drop in efficiency however can be compensated by other means.
At what angle my solar panel would sit?
The optimum angle for solar panels change in different parts of Australia however most Australian homes have a ~22 degree pitch which is suitable for solar. In case of flat roofs a ‘Tilt Kit’ can be used to achieve the desired angle.
Can I expand my solar system in the future?
Yes you can however you need to prepare yourself in advance just taking a bigger inverter doesn’t help. When the solar consultant is at your premises share this thought and they will be able to suggest you the right way to go about it after assessing your electricity use.
