Excess Solar Load Diverters

Why feed your excess solar electricity back to the grid for only 8c per kWh then pay 3 times the price when you use it?

One great was to fix this problem is to divert the excess solar electricity into your hot water system or underfloor heating using excess solar load diverters. But before we jump into it, let’s do the maths, working with typical peak and off peak tariffs available in Victoria.

Assume we have a 5kW solar system and a 3.6kW element in your hot water system. Just say it heats for 2.5 hours a day then your hot water usage is around 9kWh a day on Victoria’s off peak tariff which is cheaper than your day tariff.

Excess Power Usage 

Most 160lt and above hot water systems are able to comfortably run off peak. The above system would use 9kWh day x 365days = 3,285 kW/year. On the off peak rate of 20 cents your hot water would cost $657 a year. However if you divert all your excess solar power (worth 8c if you exported it) to run you hot water system you could save 12c/kWh or $438 year. ( now that's is your offpeak is low as 20 cents )
