When you get solar installed, a good installer will give you projections of how much you will generate per day, for every month of the year. This is ours, for those interested. They’ll also give you an estimate of how much money you’ll save, shown here too. You can see the seasonality of sunshine (length of day and angle of sun in the sky), the big dip in winter. Though even at 26 kWh per day we get more than enough for an average household. You can also use ‘time of use’ electricty rates for grid power, should you need it, which gives you cheaper power in off-peak times. If you have a battery, the battery can be asked to store energy in those off-peak times, and then deliver it to you in peak times, to save you money. It figures that all out by itself with its software, how to minimise your bill. I posted the other day that you could buy a battery for example, with no solar, and use it to store off-peak power, for you to use in peak times. There are lots of smart options.
