Although there exist different procedures and methodologies to focus the sunlight on solar panels, we have suggested a new approach to enhance the energy generation from the photovoltaic panels, i.e., by keeping the two layers of photovoltaic panels as collectors of energy one above the other with the same size and orientation. Our results of two layer solar panels have shown about 75% increase in efficiency as compared to a single layer solar panel. This study can also be extended to n number of photovoltaic layers piled up one above the other, if the cost economics are justified with respect to the land cost.
