This article is the continued investigation of the Texas Instruments BQ25570, the MPPT solar charging chip. In the following article, I will present my field tests as well as their results. I tested it with two types of solar panels, of various sizes. The tests were performed indoors as well as outdoors. The results are striking and much better than I anticipated. If your starting hypothesis was right and your lab test results were valid, then your field outcomes…

To achieve an uninterruptible operation means having an uninterruptible energy supply. One of the methods, to build an uninterruptible power supply, is to use energy harvesting techniques. This article will be an introduction to charging a lithium-ion battery with the sun’s energy. This will be the…
