ABSTRACT

The paper presents a solar radiation monitoring system, using two scientific pyranometers and an on-line computer home-made data acquisition system. The first pyranometer measures the global solar radiation and the other one, which is shaded, measure the diffuse radiation. The values of total and diffuse solar radiation are continuously stored into a database on a server. Original software was created for data acquisition and interrogation of the created system. The server application acquires the data from pyranometers and stores it into a database with a baud rate of one record at 50 seconds. The client-server application queries the database and provides descriptive statistics. A web interface allow to any user to define the including criteria and to obtain the results. In terms of results, the system is able to provide direct, diffuse and total radiation intensities as time series. Our client-server application computes also derivate heats. The ability of the system to evaluate the local solar energy potential is highlighted.

f14-sensors-08-00963: Evolution of the total solar radiation intensity, for a succession of 10 days in August.

Mentions: Figure 13 is highlighting how in three days of September, were reached high values of the total solar radiation intensity (more than 1000 W/m2). It can be observed that in each of the selected days, the morning was cloudy, and with probable rain periods, which could clean the atmosphere. In these conditions, if sun appeared at noon, the values of the total solar radiation intensity were high. Figures 14 and 15 are presenting the evolution of the total solar radiation intensity, for a succession of 10 most sunny days in the month of August respectively September.
