This graph shows the difference in production between the solar power plant on the roof and solar power plant on the tracker.
Legend:

• INV2 - 60 modules mounted on the roof
• INV32 - 60 modules mounted on trackers

The graph shows importance of the sun-tracking because with it we ensure that the sun rays always fall perpendicularly to the surface of the module and the production of electricity is significantly higher. The average difference in production in September was 52%.

The power plant on the roof produced 16,000 kWh of electricity and the one on the trackers produced 68,000 kWh of electricity.

Another interesting finding is that in case of bad weather - diffused light - it is important that the modules are positioned as horizontally as possible. With trackers we can lead to such a settlement.
