Case studies

In 2015, we helped PV system owners increase their profits by more than 10 million Czech crowns.

PV systems with centralised inverters - South Moravian Region

PID regeneration was carried out during a test run of the facility for about three weeks in January 2015. The technical parameters of all modules connected in three strings were measured before and after the regeneration. Two of the strings then took part in the regeneration process. The third one was used as a reference when evaluating the results. Measurements carried out prior to the start of the regeneration process showed a high degree of PID, namely 10-15%. This equals an annual loss of 0.5 million CZK.

PV systems with centralised inverters - Central Moravia


The power output of PV modules dropped by 4-6%. Its increase after a month of regeneration was 5.5%.
