My system was installed in April this year.
When I sum all Monthly estimates the amount is 3.240 MWh, but looking at the Yearly page it shows 3.493 MWh as estimated out.
How come?
The estimate is taken from the first 271 days of the year, i.e. number of recorded days, the results will be different if your recordings does not start from the beginning of the year.
Ok, thanks for clearing this up, but it is a strange way to calculate the yearly estimate…
For the monthly estimate out values it seems to work fine, even when the first recorded day is not on the 1st day.
So why not use these monthly estimate out values and sum all of the months for the yearly estimate out?
If there are no recorded days in the first months they will be zero.
In that way it does not matter if a systems did not start from the beginning of the year and the yearly estimate out is correct.
But perhaps more difficult to implement.
And it will also slow the page loading down as well.
