Solar panel efficiency factors

The sun beams more than enough energy onto the earth to meet the needs of global energy demand for a whole year. Solar panels produce energy less than a tenth of one percent of the entire global energy demand. The panels are called photovoltaic cells which are found on things like spacecraft, rooftops, and calculators.

The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells, it knocks the electrons loose from their atoms. The electrons generate electricity as they flow through the cell. A solar panel can generate power with a four-piece battery system that can be filled with unfiltered water, and the battery can recycle water to generate battery or power. If three panels are put together, these can produce enough electrical energy to power a home with a family of four to eight people living within the structure it is powering. It also allows a vehicle to run on solar power.

 In addition, a typical solar panel produces 200 watts of power or more. To power a building like a bank, for example, a five kilowatt-hour array, which is about 25 solar panels, is necessary. The solar panels will absorb 1,000 watts of sunlight per square meter on the panels’ surfaces. To power a high school building, a 6.25 megawatt capacity, equivalent to 24 solar panels, is needed.

There is no such thing as a perfect technology. Research reveals the different factors that can affect the efficiency of solar panel mounting systems. Some of these factors have been studied to either increase or decrease the power production from the three types of mountings such as sun intensity, cloud cover, relative humidity, and heat buildup. When the sun is in its peak (intense), during midday, the most solar energy is collected; therefore, there is an increase in the power output. Cloudy days contribute to the decrease in sunlight collection effectiveness since clouds reflect some of the sun’s rays and limit the amount of sun absorption by the panels.

During summer days when the temperature is at its highest and heat is built up quickly, the solar power output is reduced by 10% to 25% for the reason that too much heat increases the conductivity of semiconductor making the charges balance and reducing the magnitude of the electric field. In addition, if humidity penetrates into the solar panel frame, this can reduce the panel’s performance producing less amount of power and worse can permanently deteriorate the performance of the modules
