Which is very low compared to the commercial solar panel efficiency measurement system. The cost saving has been done by using lux meter instead of xenon arc lamp. Also the system measures efficiency under direct sunlight instead of laboratory AM 1.5G environment.
So, to fulfill customer rights and to know the efficiency of the solar panels, a simple portable solar panel efficiency measurement system has been designed and developed. The system includes a single Ardunio Uno, a voltage sensor, a current sensor (ACS712), a multi meter and a lux meter. The measurement has been taken under real sun conditions.
Lux meters were as follows: Lux meter 1, CEM DT-8809A; Lux meter 2, SHINWA 78747; Lux meter 3, TES-1334A. The EQE and reflected spectra were measured through the Solar Cell Spectral Response Measurement System QE-R3011 (Enli Technology Co., Ltd., Taiwan).
Moreover, in this work, a simple prototype low cost portable solar panel efficiency measurement system has been designed and developed. The system includes a single Ardunio Uno, a voltage sensor, a current sensor (ACS712), a multi meter and a lux meter.
We emphasize that a spectrometer is more reliable for measuring the light intensity of indoor light than the lux meters. We also conclude that the non-parallelism of indoor light is one of the main causes for the measurement errors and that the cell with a relatively large area is more suitable for performing PV measurement.
You can use a pyranometer for the exact measurement. As this instrument is relatively expensive you can use a calibrated REFERENCE solar cell: The LUX meter is used to measure visible part of the incident solar radiation. multiply lux to 0.0079 which give you value of w/m2. but your lux meter must be with higher reading capacity.
