New Solar tracker was invented to overcome the self contradiction of PV technology like using much land thus causing environmental damage. This makes it possible to build PV plant on a small area no matter what its topographical condition is. Therefore this can make PV plant popularized to everywhere-no matter what the size of countries are, no matter whether the country is mountainous or not, no matter how rich the country is and no matter whether the country is islands or not. This solution is very economic accessible for PV plant because a single system is not a huge scale like a hundreds MW but a much useful scale like 100~1 MW. Every country and everyone can build the needed amount of plants progressiveliy
