I = Current and V= Voltage Voc = OPEN CIRCUIT VOLTAGE We can see the point called Voc (open circuit voltage). This is the point at which there is an open circuit. This means that the PV system is turned off. As we can see, the voltage is as high Read more
Blocking Diodes A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from the battery to solar panel thereby preventing the battery from discharging. Current streams from high to low voltage, so on a bright day, the voltage of Read more
Understanding the Efficiency of Solar Modules Solar panels are usually able to process 15% to 22% of solar energy into usable energy, depending on factors like placement, orientation, weather conditions, and similar. The amount of sunlight that solar panel systems are able to convert into actual electricity is called performance, and the outcome determines the solar panel Read more
Theory The photovoltaic effect is an electrical phenomenon in which light energy is converted to electrical energy. This works on the principle of how semiconductor materials behave when exposed to light. Photons from sun rays are absorbed by the semiconductor crystal which causes an array of free electrons to be Read more
The COVID-19 had significantly affected the energy sector value chain. The international price for oil and gas has come down to a record low which we have seen in early 1995. The electricity demand has also come down by 20 to 30% due to reduced economic activities during this pandemic Read more
It is a common misconception to be confused between kW and kWh. Let us break it down one by one. kilo watt kW stands for kilowatt. A kilowatt is simply a measure of power. For example, a 10,000 watt electric shower is often referred to as a10kW shower. However, kilowatt Read more
Now that we have discussed the difference between power and energy we can better understand where each term is respectively applicable. Let us look at this into more detail with regard to solar energy. Since we know, power × time = energy & solar power × time = solar energy Given Read more
Time in the early era was always calculated on the basis Sun’s position in the sky. Solar Noon is referred to as the phenomena when the sun is as high in the sky as it will get for the day. Sunchart is revolves around the concept of the Sun following Read more
Solar Radiation can be classified into two types: Direct radiation also known as “beam radiation” or “direct beam radiation” is used to describe solar radiation travelling on a straight line from the sun down to the surface of the earth. Diffuse radiation, on the other hand, describes the sunlight that Read more
In any PV system design, it is essential to know the amount of sunlight available at a particular location at a given time. The two common methods which characterise solar radiation are the solar radiance (or radiation) and solar insolation. Solar radiance is an instantaneous power density in units of Read more
