Theoretically ideal power and energy

Inverters and installations

The theoretically achievable solar power depends on the amount of irradiation in the area of the panels.

The theoretical ideal solar power of an asset such as an installation or inverter is calculated in one of the following ways:

• Simple: In this case, only a kWp is entered. This is equivalent to a panel configuration with a single horizontal panel configuration.
• Panel configuration: One or more panel configurations are passed on for an asset, each with its own kWp, azimuth and tilt. The theoretical ideal power of the asset is calculated by taking the sum of the theoretical ideal power of the panel configurations.
• Based on the underlying devices: In this case, the theoretical ideal power of the asset is calculated by taking the sum of the theoretical ideal power of the underlying devices

In all situations, if the asset is an inverter, a maximum output power can be set. In that case, the theoretical ideal power of the inverter is reduced to the maximum output power if the ideal is higher than this value.

Panel configuration

A panel configuration is a group of panels with the same orientation (azimuth and tilt) and a given number of kWp. The theoretical ideal power of a panel configuration is calculated by calculating the irradiation in the plane of the panels at any time (in W/m²) and multiplying this by the number of kWp of the panels.

The irradiation in the plane of a panel is approximated linearly by taking the sum of the diffuse irradiation and the direct irradiation, whereby the latter is multiplied by a number between 0 and 1, depending on the angle at which the sunlight falls on the panel. This factor corresponds to the cosine of the angle between a normal vector on the solar panel and a vector oriented towards the sun.

Azimuth and tilt

The azimuth indicates how many degrees the panel surfaces deviate from the exact north orientation.

Enter in the available field how many degrees the panel surfaces deviate from the exact north orientation. For a deviation to the east, enter a positive value (e.g. 20), for a deviation to the west, enter a negative value (e.g. -20).

The performance ratio is a number expressed as a percentage and represents the ratio between the measured and theoretically achievable solar power, both calculated over the same time interval.

In the table on the overview page of the SmartgridX portal, the PR is calculated over the period of 2 days and 3 days ago, in the graphs the PR is calculated over the selected interval.

Formulas

Yf = kWh/kWp over an interval.

Yr = reference yield over an interval. If the interval is one year, we talk about the final yield.

PR = Y,f / Y,r x 100

For example:

Production currently: 15kWh

Installed power: 200kWp

Irradiation currently: 101W/m²

Yf = 15/200 = 0.075

Yr = 101 / 1000 = 0.101

PR = 74.2%

Alerts

Our portal alerts you if the PR falls below 50% and installations with a low PR can be found by clicking on the installation alarm tile, or by sorting by it.

Note that a correct PR calculation requires you to indicate how many kWp of panels are connected to an installation (or inverter). You can do this via the settings page of the installation or inverter in question.

The uptime is the percentage of time during which the installation is active during the moments when it has to perform (i.e. there is enough sun / a certain threshold has been exceeded).

The uptime is calculated over the period of 2 days and 3 days ago on the overview page of the installations, inverters and strings.

In the graphs the uptime is calculated over the selected interval.

Uptime = (Tuseful – Tdown)/Tuseful x 100

Tuseful = period in which irradiation is higher than the minimum irradiance threshold (MIT), expressed in hours.

Tdown = period during Tuseful during which the installation is not producing, expressed in hours.

MIT is typically 50 – 70W/m².

L'auto-consommation peut être calculée à condition qu'un compteur soit installé au point de raccordement.
