Implentation of solar power plant in lpu
- 1. IMPLENTATION OF SOLAR POWER PLANT IN LPU Environmental studies(CHE110) case study Under the Guidelines of Ms. Anjali Singh
- 2. Introduction The solar plant is capable of producing 99kw Per day it produces 400 to 500 units Per year 150000 units So by using Solar energy LPU is saving so much energy produced by the non renewable sources and money also LPU is contributing so much to save environment By running the solar power plant LPU is promoting sustainable development So we should use the energy properly
- 3. History of Solar power William Grylls Adams first discovered the solar energy. Inn 1953 silicon solar cells were discovered From 1956 solar cells were commercially available In 1960’s people started using solar cells in satellites Further many new modifications came up and now people are widely using solar cells for various purposes. In present days solar energy is considered as the best energy source
- 4. Components of solar power system 1.Solar panel 4.Wires 3.Solar Inverter2.Solar batteries
- 5. Working of solar panels Solar panels actually comprise many, smaller units called Solar cells or Photovoltaic cells. Many cells linked together make up a solar panel. They convert only light energy in electrical energy but not the heat energy. The photovoltaic cell is made up of an PN junction diode in reverse biased condition. When the sun light falls on the solar cell the photons activate the electrons in the diode and the electrons start to move.
- 8. Working of solar inverter A solar inverter converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating current (AC) that can be used. It gives the data about how much power was produced
- 11. Solar plant in LPU Located on the top of 38th block Constructed in 2013 Took 3 months to construct Amount of 1 crore was invested 30% subsidy was given Punjab government Produces 99kW If it is 100kW it becomes commercial So some panels are removed to get subsidy
- 12. Specifications of solar power plant in LPU Each solar panel produces: i. 250W ii. 37.25V iii. 8.75A iv. 77.06% Specifications of solar inverter: i. Max volatage-1000V DC ii. Max current-41A DC iii. Max output-3X400V AC iv. Max output-3X29A AC v. Frequency-50(or)60HZ vi. Power-19.2kW
- 13. Connections The solar panels are of “Vikram solar” company The solar inverters are of “REFUsol” company There 396 solar panels There 5 solar inverters Every 20 solar panels are connected in series These set of 20 panels are connected in parallel at the inverter All the outputs of 5 solar inverters are connected and transmitted to the sub-station In the substation the solar power is connected to the load The voltage of solar power is higher than the govt. electricity So the solar power is consumed first
Editor's Notes
- The history of photovoltaic energy (solar energy) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. The selenium cells were not efficient, but it was proved that light, without heat or moving parts, could be converted into electricity. In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, discovered the silicon solar cell. This cell actually produced enough electricity and was efficient enough to run small electrical devices. In the year 1956 first solar cells were available commercially. The cost however is far from the reach of common people. In 1960’s people started using solar cells in satellites Further many new modifications came up and now people are widely using solar cells for various purposes. In present days solar energy is considered as the best energy source
