Researchers discovered Solar System passed through two interstellar clouds creating global clouds ☁️2M and 7M years ago, plunging 🌏Earth into ice ❄️ages. Earth’s upper atmosphere received an hydrogen, compressed heliopause, and formed Global cloud layer NLC that reduced outgoing long wave radiation by 50% and sunlight at surface by 7%+.

Solar radiation takes a long journey until it reaches Earth’s surface. So when modelling solar radiation, we need to take into account various interactions of extra-terrestrial solar radiation with the Earth’s atmosphere, surface, and objects. Direct radiation The component that is neither reflected nor scattered, and which directly reaches the surface, is called direct radiation. This is the component that produces shadows. Diffuse radiation The component that is scattered by the atmosphere, and which reaches the ground is called diffuse radiation. Reflected radiation The small part of the radiation reflected by the surface and reaching an inclined plane is called the reflected radiation. And these three components together create global radiation. #SolarEnergy #SolarData #SolarRadiation #Solar #SolarPower

Take a look at my article about solar storm Solar storms are bursts of energy and particles from the Sun's surface, caused by magnetic activity. They can disrupt communication, power grids, and cause auroras. Monitoring and prediction help mitigate their impact on Earth's technology and infrastructure. One of the most famous solar storms occurred in 1859, known as the Carrington Event. It caused widespread disruption to telegraph systems and produced auroras visible as far south as the Caribbean. If a similar event were to occur today, it could have much more severe consequences due to our reliance on modern technology. #snsinstitutions #designthinking #snsdesignthinkers

▎1. Direct Irradiance - Definition: Direct irradiance is the portion of solar radiation that comes directly from the sun without being scattered or reflected by the atmosphere or surrounding surfaces. - Characteristics: - It is most intense when the sun is high in the sky, typically around noon. - Direct irradiance is responsible for creating sharp shadows and is the primary component utilized by solar panels that are oriented directly towards the sun. - Measurement: It is measured using a pyranometer or a solarimeter that has a shading device to exclude diffuse radiation. ▎2. Diffuse Irradiance - Definition: Diffuse irradiance is the solar radiation that has been scattered by molecules and particles in the atmosphere before reaching the Earth's surface. - Characteristics: - It is more uniform and spreads out over a larger area compared to direct irradiance. - Diffuse irradiance contributes significantly to overall solar energy on cloudy days when direct sunlight is limited. - It helps in reducing sharp shadows and can illuminate areas not directly facing the sun. - Measurement: This is also measured using pyranometers that do not have a shading device, allowing all incoming radiation (direct and diffuse) to be captured. ▎3. Reflected Irradiance - Definition: Reflected irradiance refers to the portion of solar radiation that is reflected off surfaces (like the ground, water, or buildings) back into the atmosphere or onto other surfaces. - Characteristics: - The amount of reflected irradiance depends on the albedo (reflectivity) of the surface. For example, snow has a high albedo, reflecting a significant amount of solar radiation, while dark surfaces like asphalt have a low albedo. - Reflected irradiance can contribute to the total solar energy received at a location, especially in areas where there are highly reflective surfaces. - Measurement: This can be more complex to measure directly but can be estimated by accounting for the albedo of surrounding surfaces and the angle of incidence of incoming solar radiation. ▎Importance in Various Fields - Solar Energy: Understanding these components helps in optimizing the design and placement of solar panels for maximum energy capture. - Climate Studies: Analyzing how these irradiance types interact with the Earth's surface aids in understanding climate dynamics and energy balance. - Agriculture: Knowledge of irradiance types helps in optimizing crop growth conditions and managing light exposure effectively. #solar #irradiance #direct #diffused #reflected #solarPV #Energy

Solar Panel Tilt Angles https://lnkd.in/dRaE8UZ5 Solar Geometric Angles are all critical to the calculation of solar energy on any given surface at some orientation. To calculate the energy balance across any time scale with respect to the incident solar radiation, you must know the geometric relationships that define the spherical realities of planetary motion relative to the sun for specific tilted surfaces on the planet.

With a solar eclipse on the horizon, we want to test your knowledge with this Astronomically fun fact! Did you know that the sun’s rays travel an equivalent of 92.96 million miles, and take a little over 8 minutes to reach the earth? Given this, how many miles will the earth travel in it’s orbit before intercepting those rays? Comment your answer below!
