  • SOME STUDENTS ASKING CIRCUIT DIAGRAM, EVEN THOUGH IF I GIVE TO CIRCUIT DIAGRAM U CAN NOT ASSEMBLED&TESTED REASON IS THE PROJECTS ARE FULLY BASED ON EMBEDDED

    MICROCONTROLLER-PIC16F877, SO U NEED TO HAVE PROGRAmming KNOWLEDGE ALSO THEN ONLY U DEVELOP THE OWN PROJECTS.

IEEE BASEDSOLAR PROJECTS:Tracking suns path for efficient use of solar cell

  1. 1. Tracking Suns Path for Efficient Use of Solar CellRenewable energy SourcesRenewable energy sources can be replenished in a short period oftime. The five renewable sources used most often are: o biomass o hydropower o geothermal o wind o solar 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
  2. 2. IntroductionWeve used the Sun for drying clothes and food forthousands of years, but only recently have we been ableto use it for generating power.The Sun is 150 million kilometres away, and amazinglypowerful.Just the tiny fraction of the Suns energy that hits theEarth (around a hundredth of a millionth of a percent) isenough to meet all our power needs many times over.In fact, every minute, enough energy arrives at the Earthto meet our demands for a whole year - if only we couldharness it properly. There are three main ways that we use the Suns energy:- 1Solar Cells (really called "photovoltaic" or"photoelectric" cells) that convert light directly intoelectricity.In a sunny climate, you can get enough power torun a 100W light bulb from just one square metreof solar panel. This was originally developed in order to provide electricity for satellites, but these days many of us own calculators powered by solar cells. 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
  3. 3. 2Solar water heating,where heat from the Sun is usedto heat water in glass panels onyour roof.This means you dont need touse so much gas or electricity toheat your water at home. Water is pumped through pipes in the panel. The pipes are painted black, so they get hot when the Sun shines on them. This helps out your central heating system, and cuts your fuel bills. However, in the UK you must remember to drain the water out to stop the panels freezing in the winter. Solar heating is worthwhile in places like California and Australia, where you get lots of sunshine. 3Solar Furnaces use a huge array of mirrors to concentrate the Suns energy intoa small space and produce very high temperatures. 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
  4. 4. Advantages • Solar energy is free - it needs no fuel and produces no waste or pollution. • In sunny countries, solar power can be used where there is no easy way to get electricity to a remote place. • Handy for low-power uses such as solar powered garden lights and battery chargersDisadvantages • Doesnt work at night. • Very expensive to build solar power stations. Solar cells cost a great deal compared to the amount of electricity theyll produce in their lifetime. • Can be unreliable unless youre in a very sunny climate. In the United Kingdom, solar power isnt much use except for low-power applications, as you need a very large area of solar panels to get a decent amount of power. However, for these applications its definitely worthwhile.Proposed Idea:Tracking Sun’s Path:Normally solar cells are placed in a ground in one direction only. But sun movesin a elliptical path. So only few hours the sunlight falls into the cell. During therest of the hours the percentage of Sunlight, which falls into the cell, is very less.Which results in less amount of energy generation.To overcome this problem we can construct a model where we can place thesolar cell in it and which can move in elliptical path .To track the sunlight. This isachieved with the help of light intensity sensors. The sensors are fixed into themodel in an elliptical path. So depending on the sunlight the sensors outputdiffers. So according position the solar panel, which results in good efficiency.(i.e.).the solar cell can produce energy by tracking the sunlight with the help ofsensors and mechanical model. The Movement is controlled by a PICMicrocontroller. Also we have an LCD Display to Show the current Position. 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
  5. 5. The delivered power of a Solar Panel is used to charge a DC Battery. Whichis finally provided to the run a small fan or to provide dc light source.
