Sun Power is the current market leader in efficient solar energy modules, the conversion ratio of sun power solar panels is 19.3%, among which Sanyo is having the most efficient modules at 20.4%. How so ever, a whole range of other companies like Holo Sun, Gamma Solar, Nano Horizons are also emerging which are offering new creations in photovoltaic modules, having a conversion ratio of around 18%. These new creations involve power generation on the front and back sides as well as increased outputs; yet, most of these companies have not produced working systems from their strategy plans, and are mostly still working in order to improve the technology. 2.1 Hardware Components : 1. Solar panel 2. voltage Regulator 3. Resistors 4. Switch…show more content…
E. Becquerel. Though, it was not until 1883 that the first solar cell was built by the scientist named Charles Fritts, who coated the selenium semiconductor with an extremely thin layer of gold in order to form the junctions. This device was only around 1% efficient. After Russian physicist Aleksandra Stoletov built the first solar cell based on the outer photoelectric effect which was discovered by Heinrich Hertz earlier in 1887. The photoelectric effect was also explained by Albert Einstein in 1905 for which he received the Nobel Prize in Physics in 1921. In 1946, Russell Ohl patented the modern junction semiconductor solar cell, which was discovered while working on the series of advances that would lead to the transistor. Chapin was the first to develop the highly efficient solar cell, Fuller and Pearson in 1954 using a diffused silicon p-n junction. In the last four decades, eccentric progress has been made, along with Megawatt solar power generating plants which are now been…show more content…
Photovoltaic modules usually have a sheet of glass on the front side, which allow light to pass while protecting the semiconductor wafers from the elements like rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. A higher current will be yielded if the cells are connected in parallel. Hence, these modules are interconnected in any way that is series, parallel or both to create an array with the wanted peak DC voltage and current. Watts or kilowatts is the unit in which the power output of solar array is measured. Watt-hours, kilowatt-hours or kilowatt-hours per day is often used to calculate the typical energy needs of the application. A usual rule of thumb is that average power is equal to 20% of peak power, each and every peak kilowatt of solar array output power is equivalent to energy production of 4.8 kWh per day that is 24 hours x 1 kW x 20% = 4.8 kWh. In order to make practical use of the solar-generated energy, the electricity is mostly fed into the electricity grid with the help of inverters, in stand-alone systems, the energy that is not needed immediately is stored in
