DiY Solar Panel & Measure Datas

Test equipment: one solar panel, 12V12AH battery, 10A solar charger. The aim of the research is to develop a power supply solution that can power our measuring and Lora GW devices in the long run. in stage 2, we continuously measure and record the voltage of the solar cell and the battery for 1 year together with the temperature and humidity data. The results of the tests, I will be made public. Anyone can use it.
