Articles and News on Solar Energy, Solar Photovoltaics and its applications, Efficiency of Solar cells, On-grid and Off-grid solar energy systems and much more. Here you will get all the technical expertise that one needs to command Solar Energy.
Characteristics of Solar Panels Open circuit voltage Voc can be defined as maximum output voltage at zero output current which means whole current flows through the diode (R is infinite). Short circuit current Isc can be defined as maximum output current at zero output voltage which means whole current flows through the load (R is zero). As we can see in figure 1,2 and ...
ICICI Lombard General Insurance made an announcement today that solar park developers can now be covered under the insurance scheme and stated " The standalone insurance product gives comfort to lenders and investors and is a perfect solution to support project finance. The product will be distributed through the company’s branches and affiliated agencies. " Alok ...
Target of 100 GW Solar energy by 2022 is set up by Government of India, motivating Indian solar PV panel manufacturers but but cheaper chinese solar modules have created a burden on these companies and have risked the employment of thousand of workers. Due to this pressure continuity on Indian manufacturers we may see increase in bad loans next year ...
Occupational Safety and Health Administration (OSHA) is an agency for safety and health legislation and have specified certain mandatory measures for ensuring safety at work place. OSHA is an act passed by United States in 1970. Many countries including India follows safety measures provided by OSHA. Guidelines of OSHA are divided into four categories : 1) Eye and face ...
What is Net Metering ?? Net Metering is an agreement signed by the system owner and utility which allows the owner to buy or sell the energy from utility using Net Meter which tracks energy exchange. An Example During early morning or evening hours when there is no sun, energy required to fulfill the load is taken from the utility grid and net-meter ...
For the past few years, much research has been conducted regarding standalone and grid-connected Renewable Energy (RE) sources all over the world. The HOMER tool has been used to analyze a hybrid electric supply system (hydro/PV/wind/ biomass) and to find the optimum sizing of components for a diesel-based RE system. The name HOMER is an abbreviation of “Hybrid Optimization ...
Government announce various schemes to provide continuous power supply to rural India. Still, hundreds of villages use chimney lamps. ‘Electrified’ villages still waiting for power. In many villages, electricity poles have been installed, but lines have not been laid. In order to improve energy security in such places we need “DC Solar Micro Grid” for providing free electricity ...
Before understanding Tilt Angle, we should get familiar with Latitude and Longitude. Latitude and Longitude are imaginary lines that are drawn on maps for locating different places on earth. Latitude is the distance toward north or south of the equator and longitude is the distance toward east or west of prime meridian. Both equator and prime meridian can be seen in the ...
1. Solar PV Panel It converts sun’s rays into electricity by exciting electrons in silicon cells using the photons of light from sun. 2. Battery Bank For Solar plant lead acid deep-cycle storage batteries are used for storing the energy generated by PV panels for providing backup to the system when sun is not present. DOD is the complement of State of ...
1. First Generation Wafer Based Silicon Cells Silicon wafer based technology is the oldest and most popular due to its highest power efficiency. First generation solar cells are of two types Mono-crystalline and Polycrystalline solar cell. 1.1. Mono-crystalline Solar Cell Mono-crystalline cells are made by cutting a block of silicon that has been grown from a single ...
Circuit of solar cell consists of current source (Ish) in parallel with a diode. As in practical conditions no solar cell is ideal, so a shunt resistance and a series resistance is considered in the circuit as shown in figure. RS is the series resistance and RSH is the parallel resistance and ID is the diode current.When terminals are short circuited, the output voltage ...
Solar cells are of tiny sizes and produce approximately one watt power. Figure (a) represents solar cell which produces voltage around 0.5V to 0.6V. As the voltage of solar cells is quite low so these cells are connected in series for getting sufficient output voltage. The series connection of solar cells is called solar module which is shown in figure (b). The voltage of ...
