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…
Basics The solar photovoltaic On-Grid systems produces, converts and transfers solar electricity to local grid in 230/400V environment. Typical characteristic of an On-Grid system is the connecting and integration with a local electric grid. On-Grid systems can be used as source of electricity for homes or factories. The user can Read more…
Basics A hybrid solar power system is combination of on grid solar system and off grid solar system. It has battery backup in it to store power and it also have the ability to feed surplus electricity into main grid. Hybrid system is fully automatic, programmable and custom engineer system. This allows a Read more…
Basics An off-grid system is not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter Read more…
