Solar power addon

Would be nice to see a setup regarding the solar which would show you own expected production from you own system
As an example i have 4 m2 solpaneler area and my solar panels will have an efficiency og 21%

So if you guys made a formal (m2*solar power)*0.efficienci in procentage

So as an example the solar power would be 500 watt
(4*500)*0.21=420 watt.
So when viewing in the solar power it would show the 420 watt which would be what my system would produce.

@frlh112 Hello, the Solar Power layer is designed for general overview, the calculation for each solar panel then needs to be done by the owner.

Hi frlh112,
In the August post on this subject, Korina mentioned that the solar power numbers were based on a flat detector at the latitude where the projection is made. So, to project your expected energy production, you will need to take into account both the angle of your panels and the length of the day. Assuming you are in Switzerland (my guess) and some of your panels are tipped towards the south, you will actually absorb more power than the projections from Windy. The straightforward calculation is based on the cos of the angle of incidence. This is simply because the projected area of the panel varies by the cos of the angle of incidence.
In order to predict the total energy over a day, you will need to have the solar power numbers for each hour of the day, corrected for the angle of incidence. Sum the total for each hour and you have total energy in kWh. This can be converted to Joules.
If your panels also have an East/West angle component you will need to calculate the compound angle of incidence. And every day the solar power, the angles of incidence and the length of the day will vary.
Hope this helps, greggy74

@greggie74 the solar panel will produce different power according to the year seasson and the sun condition, the Wp informed by companies is a referencial based on estandar condition.

greggie74

@daniel-castrom Yes, and every day the Wp, angle of incidence and length of day will vary for each panel. The only thing that cannot be predicted is the effect of weather.

@Korina Hello, the only improvement that I would suggest to the solar forecast on an hourly or daily total. That would be helpful in knowing which days to reduce the electricity usage, and how many days until the batteries can be expected to be full. I hope you can do this.
