There is no point harnessing an energy resource that has no economic value. Solar energy poses a strong threat to other forms of energy due to its purity and availability. The problem associated with harnessing solar power mainly comes from the cost and efficiency of the photovoltaic (P-V) panels. This work proffers a solution to this problem by combining the effect of colours and lenses based on the principle of white light spectrum and its behavior with lenses. A 0.9m by 0.3m mono-crystalline solar panel with a manufacturer specification of 18% efficiency, 50W maximum output power, 18V maximum voltage output & 2.77A maximum current output was used for experiments in combination with a sheet of convex lens, glass panes dyed with various colours of the light spectrum, a battery operated portable multi-meter, a meter rule, and a mount frame. Experiments were conducted for different time schedules for three days of assumed equal intensity. The results of the experiments are presented in stages and it was discovered that at stage 3, the system which is a combination of solar panel, violet colour filter and convex lens yielded a productivity of over 96% with power output of 47.67W.A. This is almost a total extortion of white light energy as provided by the solar panel
