SYSTEM FOR CHECKING THE PERFORMANCE OF ENERGY AND MONITORING PHOTOVOLTAIC SOLAR OR WIND PLANTS

摘要

The invention allows verifying the performance of energy over time of any photovoltaic or wind solar plants whose value of energy produced is made available on computers accessible through a public data communication network and monitoring the operation thereof. The performance of energy is verified by comparing the plant production values of an even long past period of time up to the start of the system, with the current ones, even if the amount of energy produced has never been measured by its user in the past. The technical problem of calculating the performance of plants referred to the initial start up values and in the past operation time of the plant itself, the automatic processing of numerous physical data, the automatic production of reports for technical and information purposes, the sending of alarms and alerts on the performance decay, is solved by the invention. The energy production values over time (even from the plant start up) are collected by computers connected to the Internet public network which present them in a hypertext structure of accessible documents, the current ones from an energy meter inserted downstream of the plant and the historical and current weather ones from computers also connected to the Internet public network. The result obtained by the system is the automatic production, i.e. in almost zero processing time, of operating reports that include the energy produced, the revenues and a performance index over time with energy performance measurements, graphs, analysis and alerts of photovoltaic solar and wind plants.
