Design And Fabrication Of Single Axis Solar Tracking System
While a majority of the world's current electricity supply is generated from fossil fuels such as coal, oil and natural gas,
these traditional energy sources face a number of challenges including rising prices, security concerns over dependence on
imports from a limited number of countries which have significant fossil fuel supplies, and growing environmental concerns over
the climate change risks associated with power generation using fossil fuels. As a result of these and other challenges facing
traditional energy sources, governments, businesses and consumers are increasingly supporting the development of alternative
energy sources and new technologies for electricity generation. Renewable energy sources such as solar, biomass, geothermal,
hydroelectric and wind power generation have emerged as potential alternatives which address some of these concerns. As
opposed to fossil fuels, which draw on finite resources that may eventually become too expensive to retrieve, Solar energy is
unlimited in availability.
Solar energy has emerged as one of the most rapidly growing renewable sources of electricity. Solar energy production does not
require fossil fuels and therefore there is less dependency on the limited and expensive fossil fuel resources. Although there is
variability in the amount and timing of sunlight over the day, season and year, a properly sized and configured system can be
designed to be highly reliable while providing long-term, fixed price electricity supply. But there is the problem of changing
angles of sunlight during a day which poses a problem for collection of solar energy.
Our project presents a solution by power generation and sensor based solar tracking system to utilize the maximum solar energy
through solar panel by setting the equipment to get maximum sunlight automatically. This proposed system keeps tracking
continuously for maximum intensity of light. When there is decrease in the intensity of light, this system automatically changes its
direction to get maximum intensity of light. Hence this system attains the maximum amount of input light on the solar panel by
tracking sunlight throughout the day thereby consequently increasing the amount of power generated.
