What is P50, P52 & P90 ?

By -
P52, P53 and P90 are terms often used in the renewable energy sector, particularly in the context of wind or solar energy production analysis. These refer to statistical probability levels used in energy yield assessments to estimate the expected production of renewable projects over a certain time frame. P50 : Represents the median or "best estimate" production scenario. It means there is a 50% chance that the actual energy production will be higher or lower than this value. It is the expected average production in a typical year. P52 or P53 : These are uncommon notations, but they might represent slight variations from the median estimate, with a slightly higher probability of occurrence than P50. P90 : This represents a conservative estimate, meaning there's a 90% chance that the actual production will be equal to or exceed this value, making it suitable for financial risk assessments. In summary, P-levels like P50, P52, or P90 provide different confidence levels for ...

Is Solar Energy a 100% Renewable Energy Source for Power Generation?

By -
Solar energy is a renewable energy source that harnesses sunlight to generate electricity. It is considered renewable because the sun provides an abundant and continuous source of energy that is not depleted by usage. How Solar Energy is Converted into Electricity: Photovoltaic (PV) Conversion : Solar panels contain photovoltaic cells, primarily made of silicon. When sunlight strikes these cells, it excites electrons, generating an electric current through the photovoltaic effect. Solar Thermal Power : In concentrated solar power (CSP) plants, mirrors focus sunlight onto a receiver. The heat energy is used to produce steam, which drives a turbine connected to an electricity generator. Manufacturing Process of Solar Panels: Silicon, derived from silica (SiO₂), is purified and melted to form ingots. These ingots are sliced into thin wafers using diamond wire saws. Wafers are processed into photovoltaic cells and assembled into solar panels. Is Solar Energy 100% Renewable? Yes , solar en...
