Objective:

• drafting proposal
• Research CICB

Content:

• Abstract & introduction
• Block diagram of CICB

Result & analysis:

• The solar energy is an energy from the sun that is converted into thermal or electricity energy.  The amount of energy falling on the earth is given by the solar constant, but very little use has been made of solar energy. The main purpose of the solar energy system as known as renewable energy is to prepare or replace for the depletion of the present source of electricity energy especially coal, oil and gas. It is possible that the world now lacks the source of energy and the world will face a global crisis of cheap oil and recommendations to a decreasing dependency on fossil fuel. This has led to increasing interest in alternate power or fuel research such as fuel cell technology, hydrogen fuel, solar energy, geothermal and wind energy. So the government encouraged to uses the solar energy system in our country in order to overcome the energy crisis in the future. This research knowledge (Development of Solar Photovoltaic Remote Monitoring System) will be hoped to help implementation of the solar technology. Furthermore each renewable energy plant or system plants needs the monitoring control systems. Same as solar photovoltaic system, where the performances and parameters must be closely monitored and controlled, thus allow adequate data acquisition system.  The data acquisition system requires large number of measured data where very frequent recording necessary needs to be automated to eliminate the probability of human error as well as to save time. This project is mainly about computer based real time monitoring system center which use Visual Basic as Graphic User Interface (GUI) to provide graphical display output chart, graph or pie chart. With VB software the solar researcher can be display the measured value from Photovoltaic house. To collect the data from Photovoltaic house to the main computer, the system require interfacing board which consist of microcontroller serial port board. reading measured data, storage data, control the system derive by microcontroller board and to interfacing the microcontroller board through main computer the project use serial port. For the convenience of researcher, the Global System for mobile communication (GSM) technology was attaching in the monitoring system to overcome data transfer. Usually the location of solar photovoltaic is different with the places where we work. So, a remote monitoring system using GSM technology has been used in this research. Beside that, the solar power system can be monitored everywhere.
