Hi guys,
we just bought a house in Sydney, looking at installing solar panels to help with the electricity bills.
has anyone had solar panels installed recently and can recommend to us.
we have a 5 bedroom house with a swimming pool.
3 adults and 2 kids.
what sort of capacity should I be looking at, would 5kw be sufficient.?
c) or west - that way you can generate power into the afternoon/evening when you are more likely to use it.
I prefer east-facing as the panels are very cool and highly efficient early in the morning. West-facing panels tend to be hot when they're in peak generation time. But then again, my system is geared for export, rather than using self-generated power, since I'm on a very generous export tariff.
But having west-facing panels is still way better than nothing, and can work very well for evening power usage. Even hot panels will still crank out those delicious kilowatts.
This is true, cooler panels will be more efficient. You really need to determine your usage patterns and export tariff opportunities to help determine the most efficient layout on your roof. The most efficient power generation may not be the best financial model. it's a compromise between all the factors to determine what is most effective for you.
This is a good guide to start your research:

Our system is 4kw for 5br home with pool and off peak HWS. We use barely any AirCon in summer and gas heating in winter. Half the panels on an unshaded north roof and half on unshaded west. We used approx 24-26kWh per day prior to the install and usage dropped to 16-18kWh post installWe are exporting 11-17kWh. We are generating up to 24kWh per day in perfect conditions. This is in Hunter Valley so not dissimilar to Sydney.
At the time 5kW and battery would have been nearly enough to go off grid, but the cost was high!
Before anyone can be properly helpful on the recommended size of a system, I suggest you indicate:
a) Your typical electricity usage per quarter, in kW (check your last few bills)
b) Where your highest usage is likely to come from (pool filter, AC perhaps?)
c) Do you have a large area of roof that's unshaded and facing north, or perhaps east? A 5kw system could take about 40 square metres.
Other helpful information could include your energy source for cooking and hot water (electricity or gas).
