Analysing quarter by quarter electricity consumption helps to identify which seasons have the highest energy.  Generally, in cooler climate zones that are heating dominated, winter will have the highest energy use.  In the warmer cooling dominated climates, summer generally sees the highest energy consumption.

Even though your home may achieve the zero energy balance, you might still end up having to pay for connection to the electricity grid.  In addition, most electrical retailers only pay a minimal amount for excess electricity you put into the grid compared to the electricity you purchase from the grid. Having batteries installed can help even this out and can also provide you with electricity if there is a disruption to the grid.

Electricity produced from roof top mounted solar panels is the primary method used for generating renewable electricity at your home.  Solar input will vary over the year depending on the amount of sunlight that their receive.  In southern latitudes during winter, solar generation is significantly reduced.

Analysis of daily usage helps to identify those peak days and times of the year.

Detailed timed usage data helps to understand what times of the day are peak energy use times.  Often peak use times and peak generation times do not align, so if it is possible to shift some of this peak use activities to times of peak generation, then less electricity will be exported to the grid.  Charging of batteries and EVs can also be scheduled for peak generation times.
