How to maximize CO2 reductions

See how to cover the emissions of 4 other houses as well as your own with solarprod.

Solarprod has very sophisticated algorithms to determine the best way to use the stored power in your battery. We offer several optimisation options to use this power, depending on your goals. By default, we use your battery to make you the most money (Best price). In this blog post, we show you how to maximise CO2 reductions instead.

To do this simply choose the "Lowest Co2" option in the dropdown box (see blow).

Now when you do calculations, like the week ahead calculation below, Solarprod works out the best way to use your solar power each day, together with the best way to import and export electricity to reduce the total CO2 emissions of the grid. The graphs below show how this works for a house in Melbourne over a week in October.

The total CO2 reduction of this solution is calculated to be 210 kg over 7 days. How does this work? Look at the graphs below, especially the bottom one.

Here we show a plan for how much and when power is imported and exported to the grid to maximise CO2 reductions. Note that exports always occur when the grid has the highest CO2 intensity. That means your emission-free solar, along with low-CO2 grid imports, displaces high-intensity electricity. Calculated over one week, the total displacement is 210 kg. That's equivalent to driving 1000 km in an average car! Also note that most of the effect is from your solar exports: 183 kg. This is much bigger than simply avoiding your own CO2 emissions (50 kg) in this example, and it shows how you can actively reduce emissions overall. In this example, the effect is cancel out the emissions of 4 other houses as well as your own.
