“…The temperature dependence is the most important factor [45,47]. In Figure 8, it is shown that the original cells (uncorrected signal), which do not include the temperature sensor, have a CV higher than 7.5%, which excludes it as an acceptable model, whereas the CV of the corrected sensor is less than 1%, or within the category of very high precision models [74,75].…”

“…There are papers that have modeled the thermal dependence of this type of sensor performing laboratory tests [45], and other authors with similar objectives have carried out the tests in outdoor conditions [44]. In this case, the use of natural radiation was chosen, tests were carried out in outdoor conditions in order to model the influence of the transient thermal drift as realistically as possible.…”

“…Plesz et al [45] have studied the working principle, design, and thermal characterization of a low cost solar irradiation sensor. The sensor is based on a photoelectric cell and thermal tests were performed in a climate chamber in the temperature range of −20-80 • C in increments of 10 • C. They conclude that the self-made solar cell's thermal dependence was 0.26% • C −1 , revealing higher temperature dependence than in the case of an industrial reference cell.…”

Abstract:The energy consumed to cool buildings is very elevated and solar gains represent a high percentage of these cooling loads. To minimize the thermal load it is necessary to control external shading systems. This control requires continuous measurement of solar radiation in different locations of the building. However, for such applications the use of conventional irradiance sensors increases the cost and reduces the profitability of the installation. This paper is focused on the development, modeling, and experimental validation of low cost irradiation sensors based on photovoltaic effect in order to reduce the costs of dynamic external shading devices and to improve the profitability of the system. With this proposal, firstly, small commercial photovoltaic cells have been adapted for use as an irradiation measurement device. Subsequently, quasi-stationary and continuous experimental measurements of these silicon cells, facing south and installed horizontally, have been carried out in Jaén (Spain) in 2009 and 2010. Finally, a nonlinear multiparameter function has been developed to evaluate the irradiance using the electric current generated by the cell, cell temperature, ambient temperature, and absolute humidity. A favorable agreement between the model predictions and experimental data has been observed with a coefficient of determination around 0.996 for all cells.

“…Photovoltaic detectors that have been integrated in various types of irradiance measurement systems [7] [8] are typically chosen for solar heat flux measurements because of their relatively accessible prices and ease of use [9]. However, they are sensitive to the spectral distribution and ambient temperature [10] [11].…”

Development and assessment of a low cost sensor for solar heat flux measurements in buildings

This paper presents a new type of low cost solar sensor, i.e. a black and white sensor (BWS). The BWS uses the difference in temperature of a white surface (solar energy highly reflected) and a black surface (solar energy highly absorbed) to estimate the solar heat flux through building openings. Results are obtained through a correlation based on a thermal model of the sensor. The correlation contains calibration factors determined from an initial on-site calibration. Results of estimated solar heat flux with two designs of the BWS over two different periods of time were compared with solar measurements of a high precision pyranometer. The two designs of BWS have shown mean weighted relative errors over the sampling periods under 4% for the daily integrated solar energy measured. Finally, a sensitivity analysis of the calibration period was conducted and it was observed that ideal calibration period should consider at least half a day of measurements, including solar peak time, and should be done during clear sky conditions.
