No. That assumption is incorrect. At the equator there is little loss due to the atmosphere. Moving toward the poles, the atmosphere blocks more and more radiation.
Due to rotation of the earth, the effect becomes even stronger. And at the poles there is for a long period of the year even zero sunlight. .
Also note, the best area is not necessarily directly on the equator, because photovoltaic solar panels produce less energy at higher temperatures. Best place: a cool site, on a high mountain, somewhere in the tropics.
OP forgot to incorporate the tilt of the earth into their diagramm as well.
