Today the customer was fortunately enough to have three-phase, which gave the ability to go up a seven kilowatt inverter and allow us to chuck 9.3kW worth of PV on the roof, which is around 27, 345s. The house is basically got a near perfect pitch, facing north, which is really great for installing solar panels obviously. So where we've actually pin pointed to put the solar is basically where there's no shading at all, and the best outcome will happen due to the sun being able to hit those panels all day long without any shading issues. Working with this particular customer, she wanted quality, reliability and efficiency. And the first brand that come to mind obviously was LG. The LG345 NeON? 2, basically ticked all three of those boxes. So she went with that. Customers like this, we really love to work with, because they want quality, and LG gives us the ability to offer quality and give them confidence for the future.
The return on investment for a property like this is around three years. In Darwin we're still experiencing a one for one tariff, which basically means you will sell your power back to the grid for the same price that you purchase it for. The residential sector really looks for maximizing their systems straight off the bat. So commonly we'll install five kilowatt inverter on a single-phase, and a seven kilowatt on a three-phase, pump that up to 9.3 or 6.6. Out of that the customer obviously makes around, you know, 30 to 43 kilowatt hours per day and it saves her anywhere from $700 -$900 a quarter. For the home consumer, she has three-phase, which is great, which means we can upgrade the system to a seven kilowatt inverter, and go up to around 9.3 kilowatts worth of PV on the roof.
For a single-phase we would usually do a five kilowatt with around 6.6 kilowatts. So the advantage is to grab that extra three kilowatts and really create more power.
What are the advantages of having three-phase power for homeowners around Darwin installing solar?
