Abstract: 
Nowadays, with the development of industry, people need more and more energy. Most of the portion of energy is from burning fossil fuel but the amount of fossil fuel is going to be exhausted soon. Moreover, when burning fossil fuel, it produces a big amount of CO2, a greenhouse gas, which contributes to global warming and climate changing. We need to find out a better and more environment-friendly source of energy for our life. Renewable energy is a resource that we can explore. Renewable energy, which takes energy from nature source like wind, sunlight, ocean tidal, geothermal… can be considered as a non-exhausted source of energy.
Among the renewable energy, solar energy is the easiest type to access for normal household. Solar cell technology offers a number of significant benefits, including:
 Solar power is a renewable resource that is available everywhere in the world.
 Solar PV technologies are small and highly modular and can be used virtually anywhere, unlike many other electricity generation technologies.
 Unlike conventional power plants using coal, nuclear, oil and gas; solar PV has no fuel costs and relatively low operation and maintenance (O&M) costs. PV can therefore offer a price hedge against volatile fossil fuel prices.
 PV, although variable, has a high coincidence with peak electricity demand driven by cooling in summer and year round in hot countries.
More and more people are using solar panels to power their home by using solar panel system. Most of people put their solar panels on the house root or fixed it on the support frame but the sun moves in the sky during the day, the angle of sunlight with the solar panel varies. Solar panel has highest efficiency when sunlight is perpendicular to the panel. When we fixed the solar penal, most of time, the angle of sunlight and solar panel is not at right angle so solar panel can’t receive the maximum power of sunlight. This is a waste of resource as solar system can collect more energy if it always faces to the sun. To keep the solar panel faces to the sun, we need a solar tracker. The tracker is a device that keeps the solar panel follows the sun during daytime, so the sunlight always hit the panel at right angle. Hence, the tracker can help to increases the amount of energy collect daily.
