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 Read more
Module Mismatching When PV modules are connected in series, there is something known as “the Christmas light effect”. If one module has less current, then it eventually limits the amount of current to flow through the whole series-connected PV source Read more
For fenestration with a permanent external projection, including but not limited to overhangs, side fins, box frame, verandah, balcony, and fixed canopies that provide permanent shading to the fenestration, the equivalent SHGC for the proposed shaded fenestration may be determined Read more
The attempt to renegotiate solar projects tariff by states such as Andhra Pradesh Gujarat Uttar Pradesh and Telangana is not a healthy sign for the investors in Renewable Energy Projects. During last decade we have witnessed that solar tariff have Read more
China’s imports have come recently into the spotlight because of the Indo Chinese geopolitics and conflict on the Doklam Valley. While Indian government has already imposed safeguard duty of the order of 20% on solar PV modules and cells. Be Read more
For all climatic zones, vertical fenestration compliance requirements for all three incremental energy efficiency levels, i.e. ECBC, ECBC+, and SuperECBC, shall comply with the following: (a) Maximum allowable Window Wall Ratio (WWR) is 40% (applicable to buildings showing compliance using 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 Read more
U-value Thermal transmittance (U value) is the heat transmission in unit time through unit area of a material or construction and the boundary air films, induced by unit temperature difference between the environments on either side.Unit of U value is Read more
What is Daylighting? Daylighting is the controlled admission of natural light, direct sunlight, and diffused-skylight into a building to reduce electric lighting and saving energy. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, 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 Read more
