 +====== Audit ======
 +
 +
 +It compares estimated and real output of a PV plant in a particular year. Data is presented on condition that you fill in information in submenu Administration/Data for audit.
 +
 +
 +=== Graph's time period ===
 +
 +
 +Graph can show a particular year. Time period stipulates the year shown in the graph.
 +
 +
 +{{:sim:portal:graph:previous.png?nolink&}}button **Previous** shifts time period one year backward. When we click on back arrow and it shows the previous year etc.\\ 
 +\\ 
 +{{:sim:portal:graph:next.png?nolink&}}button **Next** shifts time period one year forward. When we click on forward arrow and it shows the next year etc.
 +
 +
 +    * **A year**  (a current year) - when you click here it shows a graph of a current year.
 +{{  :en:sim:portal:graph:audit.png?direct&200  }}
 +
 +
 +=== Annual audit ===
 +
 +
 +A survey of real enrgy output in each month of a particular year compared to output estimated by PVGIS a ČHMÚ.
 +
 +
 + \\ {{:en:sim:portal:graph:audit-pvgis.png?nolink&}}Output estimated by PVGIS. PVGIS is a mathematical model of European Committee that can calculate energy production in a particular place in Europe or Africa. It uses both data from satellite measurement and ground meteorologic stations. \\ {{:en:sim:portal:graph:audit_chmu_2.png?nolink&}}Output estimated by ČHMÚ. Data ČHMÚ come from measurement of ground meteorologic stations. \\ {{:en:sim:portal:graph:audit-vyrobena_energie.png?nolink&}}Real energy output of your PV plant.
 +
 +
 + \\ Vertical bars of a corresponding colour show monthly production, horizontal bars of a corresponding colour show average annual production.
 +
 +
 + \\ {{  :en:sim:portal:graph:audit_3.png?direct&600  }}
 +
 +
 + \\ Click here {{:en:sim:portal:graph:audit-tabulka_2.png?nolink&}}to show the survey of output with average irradiation.
 +
 +
 +=== Survey of output with average irradiation ===
 +
 +
 +It provides detailed survey and compares monthly irradiation values with estimated and real production. \\  \\ **Average irradiation [W/m2]**  \\ Average of values from the irradiation sensor ( on condition there is an irradiation sensor connected to the Solar Monitor unit). \\  \\ E**nergy produced  [kWh]**  \\ Energy really produced per month.
 +
 +
 +    * red value - estimated output higher than real
 +    * green value - real output higher than estimated
 +
 +
 + \\ **PVGIS [kWh]**  \\ Estimated production according to PVGIS. \\  \\ **ČHMU [kWh]**  \\ Estimated production according to ČHMÚ.
