How to Measure Efficiency
Put simply, the efficiency of a PV Solar cell can be defined as its ability to convert sunlight into usable energy for consumption by the consumer; or in technical terms, peak power output (Wp) x peak sunlight hours (h) = expected energy output (Wh). Using a Solar cell with a higher efficiency rating offers the consumer the opportunity of installing a smaller system, as the maximum amount of energy can be generated using fewer panels.
Until recently, the highest rated efficiency Solar Cells delivered a rating of between 14.5%-15.5%, however, earlier in 2011, a new product was introduced to the UK market which looks set to revolutionise Solar Panel installations in the years to come.
The Sanyo Innovation
On gaining MCS (Microgeneration Certification) accreditation in February 2011, Sanyo Component Europe GmbH (SANYO) was free to launch its HT series N2205E10 Solar cell on to the UK market in March 2011. Believed to have the highest efficiency rating of any Solar panel currently available in the world, the N2205E10, already used commercially in mainland Europe, needed the MCS accreditation prior its use in the UK. Consumers wanting to install solar technology on their properties, and benefit from the government backed FIT (Feed-in Tariff), can only use cells with MCS accreditation in order to comply with current legislation.
The HIT N2205E10 Technology
The innovation behind the efficiency of these cells comes from their construction using HIT technology. Heterojunction with Intrinsic Thin Layer or (HIT), combines singl
