I've run Google translate over Werk_AG's orginal post which translated it from Portuguese to English (quite well I must say too?) as it's quite interesting and something I'd like to do with my WeatherDuino Pro2 in the not too distant future.
Measuring Solar Radiation based on Photovoltaic Cells
One of the most frequent requests for information that come to me is on the meter Solar Radiation used here in MeteoCercal. For this reason I decided to choose precisely this theme, one of the first topics in this section.
For purists, it is clear from the outset that I will not write about building a real pyranometer, but about simple equipment Constructed using economic materials and easy to purchase. Do not have a laboratory quality, but it has enough to get the measurements that can be observed in Meteocercal, and that over time have proven very comparable to those obtained by reputable brands, quality stations located nearby.
By way of example, below a graph generated by Cumulus corresponding to the day 5/3/2014.

Prelimiar made this explanation, then move forward:
Step 1 - Study of Theory
For building success with this equipment, it is very important to understand the principles on which it is based. That said, the first step is to thoroughly investigate the matter in an article authored by Charles G. Wright , whose link I indicate below.
Measuring Solar Radiation
Again I mention that before proceeding, it is very important to realize that perfectly understood the theory presented in the previous article, because the steps depend on it.
