I. What are Thin-film Solar Cells? Thin-film solar cells are a type of photovoltaic technology that is made by depositing one or more thin layers of photovoltaic material onto a substrate. These cells are much thinner and lighter than traditional silicon-based solar cells, making them more flexible and versatile in terms of installation options. Thin-film … Read more
I. What is Solar Radiation Budget? The solar radiation budget refers to the balance between the amount of solar radiation that reaches the Earth’s surface and the amount that is reflected back into space. Solar radiation is the primary source of energy for the Earth’s climate system, driving processes such as temperature variations, weather patterns, … Read more
I. What are Solar Energetic Particles? Solar energetic particles (SEPs) are high-energy particles that are emitted from the sun during solar flares and coronal mass ejections (CMEs). These particles can include protons, electrons, and heavier ions such as helium and oxygen. SEPs can travel at nearly the speed of light and can have energies ranging … Read more
I. What is Thermography in PV? Thermography in PV, or photovoltaics, is a non-invasive technique used to detect and analyze temperature variations in solar panels. By using infrared cameras, thermography allows for the visualization of heat distribution across the surface of solar panels, providing valuable insights into the performance and efficiency of the photovoltaic system. … Read more
I. What is Community Solar? Community solar is a solar power system that is shared by multiple community members who receive credit on their electricity bills for their share of the power produced. This allows individuals who may not be able to install solar panels on their own property to still benefit from clean, renewable … Read more
I. What is a String Inverter? A string inverter is a crucial component of a solar energy system that converts the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used to power homes and businesses. It is called a “string” inverter because it is typically connected to … Read more
I. What is Direct Normal Irradiance (DNI)? Direct Normal Irradiance (DNI) is a measure of the amount of solar radiation received per unit area by a surface that is always held perpendicular to the rays that come in a straight line from the direction of the sun at any given time. In simpler terms, DNI … Read more
I. What is a Heliostat? A heliostat is a device used in solar energy systems to reflect sunlight onto a specific target, such as a solar receiver or photovoltaic panel. The word “heliostat” comes from the Greek words helios, meaning sun, and stat, meaning stationary. Heliostats are typically large mirrors that track the movement of … Read more
I. What is a Solar-Powered Adsorption Chiller? A solar-powered adsorption chiller is a type of cooling system that uses solar energy to drive the cooling process. Unlike traditional air conditioning systems that rely on electricity to power compressors and refrigerants, adsorption chillers use a chemical process to produce cooling. This makes them more environmentally friendly … Read more
I. What is a Solar Cell Backsheet? A solar cell backsheet is a crucial component of a solar panel that serves as the outermost layer protecting the solar cells from environmental factors such as moisture, heat, and UV radiation. It is a thin, durable sheet that is placed on the back of the solar cells … Read more
