Combining advantages of photovoltaic（ PV） grid-generation and energy-saving control

an intelligent control system is completed

which is based on programmable logic controller（ PLC）. A distributed structure is used

industrial Ethernet is used to achieve the communication of PLC of lower PC and touch screen of upper PC and Groov server and remote publishing

real time remote monitor based on network is achieved. By intelligent control

energy consumption of this system is reduced and the objective that there are an appropriate illumination and air quality and constant temperature in the house is accomplished

and balance between grid-generation capacity of PV system and power consumption of system.
