  Some of the words and abbreviations used any time describing the solar PV system can be confusing, especially when trying to take in all the information at a time. Below is an attempt to explain some of the terms used in describing photovoltaic systems and how people work. Hopefully it easy to understand.
  
  We are always willing to help explain things, if we have missed something, or there is something you intend to know then please get in touch.
  
  Solar mobile or portable. This is the electricity producing the main system. Cells are grouped together to create a module.
  
  Solar module. A collection involving cells joined together. The group of cells is often a part of an aluminium frame. Otherwise known as a solar panel, though this term more correctly relates to a solar hot water collector.
  
  Sun array. This is when a number of modules are joined together to obtain electricity. Most often for a roof, but can get anywhere, solar power stations may be built in fields or the desert!
  
  Roof mounted. When the array is placed on a frame that is attached to your roof.
  
  Roof integrated. When the array is mounted inside roof, replacing the top material.
  
  Inverter. The inverter converts the DC electricity produced by the array into AC electricity utilised in the national grid.
  
  Age group meter. The generation meter records everything made by the solar PV system. (this is used for your feed in tariff payment)
  
  Isolator. The isolators are switches that break the connections with the circuits in the PV system. The DC isolator turns the electricity from the solar PV array don / doff and the AC isolator turns the mains supply on and off.
  
  Electrical Words and Abbreviations
  
  Kilowatt (kW). This is the standard unit of power. Your electrical appliances are going to be labelled with a kW rating. Your microwave might be a 1000w for example. 1000w is usually 1kw.
  
  Kilowatt/hour (kWh). When your 1kw microwave runs for just one hour it has used 1kWh of energy. The kWh is a unit useful to measure how much electrical power is used over a period of time.
  How much are you looking to invest?
  
  Obviously, the cost of a great installation is dependent on the size of your installation, which itself is dependent on several things:
  
  • The top area of roof well suited for solar panel use.
  
  • Your usage needs.
  
  • Your budget
  
  You benefit from greater value for money on a larger system as a result of economies of scale, but a sizable system can become very expensive very quickly. The typical solar panel installation on a UNITED KINGDOM home is approximately 3kWp and will cost around?? 8000 -?? 10, 000 (including VAT in the rate of 5%). Make sure to get quotes from numerous installers though, because prices can vary quite widely. A 3kWp system will save you around?? 70 per year on the household bills and prevent around one tonne of skin tightening and emissions every year.
  
  How much can I earn in the Feed in Tariff?
  
  By installing solar panels somebody only doing your part for the environment and saving on your electricity bills, but additionally you can earn an income every year for 25 years, thanks to the government's feed in tariff. Solar Panels Yorkshire
