Solar Cell Capacity Improvement Using Fresnel Lens Concentrator with Solar Tracker Control

The current solar panel efficiency level reaches only about 5-16% of the total solar energy that can be converted to electrical energy. Even to get a high level of efficiency requires high quality solar panels and expensive investment costs. So to increase the efficiency required tools to increase the intensity of sunlight by combining solar panels with Fresnel lens and use solar tracker control. Solar tracker working system is to find the direction of the coming sun that uses two sensors that provide information on the intensity of light received by each sensor. The characteristic of the Fresnel lens is similar to that of a convex lens that collects light and passes it into a single focal length. Based on experimental results with a 20 ° deviation angle facing north using Fresnel lens optimization has increased power in sollar panel by 119.2%. From the results of the overall test, the highest power was obtained at sollar panel output using Fresnel lens optimization of 29.7 watts. While the experimental results using diesel tracker, the average voltage percentage is 6.1% larger on the first day, the average percentage of average voltage is 3.8% on the second day, and on the third day the average voltage is 6.1 %.
