Micro renewables - Photovoltaics

Solar photovoltaic (PV) uses solar energy to generate electricity for appliances and lighting. PV systems use solar cells, made up of one or two layers of semi-conducting material. As light falls on the solar cells, an electric field is created causing electricity to flow. Whilst higher levels of sunlight will result in more electricity being generated, the system does not rely on sunshine to function – daylight is sufficient.

Solar PV requires south-east to south-west orientation. They can be stand alone (i.e. positioned away from the building), and either mounted or integrated on either the roof or the wall. For example, PV tiles can be fitted instead of roof tiles. This section provides more detailed information about solar photovoltaic systems.

This is a comprehensive document on the use of photovoltaics in building design. Section 3.6 'Forms and Systems' (p 21-27) provides a useful guide to the different applications available (with photos) and section 4 (p 47) introduces the calculations involved in sizing and costing systems. Cambridge Botanic Gardens provides the case study and there is a handy PV glossary on pages 62-64. (DTI ref. URN 99/1274).v show details

A review of active solar heating systems installed in Northern European countries. Section 3.4.6 (p 23) considers the relevance of this data to the UK and Annex 1 (p 28) provides a useful list of parameters for measurement when monitoring an active solar system. (DTI ref. URN 00/1673).v show details

This document includes the results and analysis from a two year (1998-1999) performance study of 4 active solar water heating installations. Outputs of the study include data on quality of collector performance, information on hot water usage and delivery temperature, output from collectors and proportion of household hot water requirement met by installation. Comprehensive data is presented which may be of use when assessing the suitability of solar thermal installations for a property/ies. (DTI ref. URN 01/781)v show details
