The constraints in using solar panels during is the absorption capability from the panel itself so it can not store electricity optimally.To overcome this problem, a company in Israel has developed a solar panel that has two sides which is claimed able to absorb more energy, the bSolar.
bSolar is having a solar panel on both sides (front and rear). And if this solar panel positioned vertically it will absorb 50% more energy and only about 10-30% when positioned like a regular solar panel installation.
Unfortunately, there is no further information about bSolar pricing and its availability.Source: bSolar
