Since I first came across solar energy in the newspaper, I was already fascinated that I always try to find updates on the technology. There was even a Solar company here that sells solar energy system. But based on my research, the solar panel is affordable but the battery is the crux. A simpl computation would take 20 years for the cost to be recouped and in that span of 20 years, the battery would need to be replaced several times. That means solar power is not cost efficient for now.
