For a street light that consumes 900WH, after calculation, the battery panel power required by the former =900*1.333/6.2=193.5 Wp, and the battery panel power required by the latter=900*1.333/4.6=260.8 Wp. From this we can conclude that the more sunlight there is, the smaller the solar panels you need and vice versa.
