When you decide to place a photovoltaic system to provide electricity and use clean energy sources as best as you can, first you need to take a look at the amount of radiation got to the ground and received by the pannels. So it is better to select an area of ground that receives much radiation and most of the time it happens in summer months when the sun is above our head and in the middle of the sky. Congratulations now you can choose a photovoltaic system and install it. But wait there is one more thing. Here you can see why we can not rely on solar radiation in a month of the year while it has the most and least energetic rays about to place a photovoltaic system or deciding on something else like water heating systems or thermal systems. So it has special analysis when you decide to install an efficient renewable working system.

Sun is a free source of energy that we use it to generate electricity with photovoltaics but that's not all the story about it. Solar thermal energy is another form of energy in solar beams emitted by the sun to the earth as a reason for the vaporization of seawater. Also, solar thermal energy causes the flows of air - winds and flows in oceans all around the globe. It changes the seasons of the year.  Additionally, solar thermal energy is a source of heat in passive or direct forms like preheating or warming water or air by solar collectors to run a power plant, provide domestic hot water or using solar radiation coming through windows directly into space. Now it is possible to use this clean and free energy in our homes and for portable use by application of new packaged collector technologies. So our team designed a solar thermal system in details on the roof of the building. This is a simple design of a solar thermal system.

As the world is going through growing in all aspects to better live by developing new technologies and a new standard of living, the people in a country will increase their use of energy to use that technology and that technology makes it easy to solve our problems until we get in trouble by facing with global warming and climate change or random events caused by nature.  Then, by the way, the source of energy we use is important.  We know that Renewables are the best solution as a reliable and free source of energy; photovoltaic systems produce electricity.  We designed a photovoltaic system and video shows the simulation and layout of that system in the project. Study of shading impact during a day (from 7 am to 4 pm) is the main target of this simulation.

  Energy is something that we are using in our daily life on our planet earth to power our machines and bring comfort to our lives.  Electricity  and  Heat  are the most common  types of energy  that we are using in our homes.  we use electricity to turning lights on, washing clothes, playing video games, cooling ourselves in hot days of summer, having access to the internet, watching television and taking shower by cleaned and pumped water into our homes, etc. we also consume fuels to heat ourselves in winter and cold days.
