The PCB board used in the earlier version was made of all SMD components as result users who don't have SMD soldering experience can't take advantage. So I thought to redesign the PCB by using all through-hole components so that anyone can make it.
This board can easily be assembled by school children which can be used for STEM education in the school. By making this project they will aware of the sustainability and use of renewable energy.
Now the kit is available on Tindie
