Introduction
Optimizer by Forcast.Solar focuses on optimizing self-consumption and helps to predict how your own electricity from the PV system can be used optimally.
Based on these recommendations, self-consumption can be controlled, the consumption of expensive grid electricity and electricity costs can be reduced and energy independence can be increased at the same time. In practice, the time of electricity consumption hardly coincides with the time of solar power generation by the PV system.
Self-consumption is defined as the portion of photovoltaic production that is consumed on site. Maximizing it is synonymous with maximizing the positive share of the remaining PV generation that results after deducting uncontrollable electricity consumption.
Surplus, self-generated solar power is sold to the grid operator at a very low price, while expensive grid electricity has to be purchased if the PV system generates no or too little solar power. So why not consume more electricity when the PV system is generating electricity and save electricity at night or in bad weather?
To use the Optimizer, you need at least a "Professional" account.

Data
The optimization is based on your
- location (latitude, longitude)
- declination and azimuth/orientation of the solar panels
- loads definitions
You can download your data variant and upload it again later.
Location
Planes
You can define up to 3 planes (Professional) resp. 4 planes (Professional Plus) as described in the documentation.

Optimization data
If you notice any inconsistencies/anomalies in the calculation, please send me an e-mail and always include the following information:
- What did you expect as a result and what do you think is not as expected, describe as precisely as possible what you found.
- The full content from "API call" below

How to interpret ...
- Starting with forecast and consumption(s), the development of the energy balance is calculated.
- The optimizations during the best variant were run through in the order shown and the value after each step is the kWh balance.
- After the last step, positive values represent an energy surplus (Feed-in), negative values an energy deficit (Electricity purchase).
