Description

A solar resource monitoring system based on Beidou satellite system

technical field

The invention relates to the field of solar resource monitoring, in particular to a solar resource monitoring system based on the Beidou satellite system.

Background technique

At present, the solar energy resource monitoring device usually uses an illumination radiometer to record solar power data, and then transmits the data to the monitoring terminal server through a wired network or wireless GPRS, 3G and other methods. The information of solar observatories is transmitted through wired network or GPRS, 3G and other wireless methods. However, there are no GPRS and 3G signals in uninhabited remote areas or mountainous areas, and it is not necessary to lay communication lines. Resource areas are uninhabited and have no corresponding communication lines.

Existing solar energy evaluation methods usually evaluate local solar energy resources from a macro perspective through the long-term climate information of the region. However, specific solar energy resources at the location of the solar power station need detailed output power of solar panels, solar energy changes in a day, long-term changes in temperature and humidity, wind power and other power station construction evaluation information, directly using solar cells as sensors Measuring the intensity of solar radiation is more practical for photovoltaic power generation.
