Hush Speak – Our list of common solar terms, L to Z
Large-Scale Generation Certificate (LGC. Formerly known as a Renewable Energy Certificate) – Under the Enhanced Renewable Energy Target, an LGC is a certificate with a fluctuating price that is created and issued to both individuals or organisations who create large-scale renewable energy projects. These may include solar PV and concentrating solar power plants. Light-induced degradation (LID) – While many solar panel producers utilise anti-LID technology in the production of their systems, light-induced degradation occurs over time when photovoltaic cells lose efficiency due to constant insolation (exposure to the sun).
Megawatt (MW) – a MW is equal to 1000 kilowatts (kW) of power. Monocrystalline Cells – a solar cell made from a single, large silicon crystal Multicrystalline Cells – multicrystalline cell material consists of millions of small crystals of silicon.
Operating range (referring to an inverter) – The operating range refers to the voltage or power range that a solar inverter functions within.
Peak efficiency – refers to the highest level of output efficiency an inverter or solar panel can achieve. Photon – a light particle. Photovoltaics (PV) – the tech that converts sunlight into useable electricity. This is generally semi-conductor based. Polycrystalline Cells – Polycrystalline material consists of millions of tiny silicon crystals, as opposed to one large silicon crystal (like monocrystalline). Power Purchase Agreement (PPA) – the legal document that binds your electricity supplier to you, the buyer of electricity. In regards to solar, it is the agreement contract that will govern the terms when you sell power back to the grid.
Renewable Energy Certificate (REC. Now known as a Large-scale Generation Certificate) – Under the Enhanced Renewable Energy Target, an REC is a certificate with a fluctuating price that is created and issued to both individuals or organisations who create large-scale renewable energy projects. These may include solar PV and concentrating solar power plants.
Small-Scale Technology Certificate (STC) – A certificate with a fluctuating price that is created and issued to individuals who create small-scale renewable energy projects under the Enhanced Renewable Energy Target. An STC includes solar PV systems. Solar Cell – The silicon wafers used to make solar panels. Polycrystalline solar panels have rectangle shaped cells, while monocrystalline solar panels generally have diamond shaped cells. Solar Power – The generation of power from the sun through a variety of means, but primarily through photovoltaic technology, solar thermal or concentrating solar power. Solar Installer – Hush Energy J. More broadly, any person or company who installs solar power systems Solar photovoltaic effect – the process in which electricity is produced through the conversion of sunlight when using materials with photovoltaic properties. Solar Panel – the panels that are mounted to your roof (for example) in an array and which are composed of solar photovoltaic materials, which convert sunlight into electricity. Strings – Similar to an Array, a string refers to the number of panels linked in a line across your roof. Depending on the size of your solar system and the voltage of each panel, you may have around ten panels linked into a string.
Ultraviolet (UV) – refers to an ultraviolet photon, which is a light particle that is emitted from the sun in a nuclear fusion of hydrogen.
Volt (V) – is a unit of measurement, measuring voltage. Volts x Amps (current) = Watts.
Watt (W) – a basic unit of measurement used to determine the capacity of electricity generating devices, such as solar panels.
