PV requires only daylight &#8211;  not direct sunlight &#8211; to generate electricity, so can still generate some power  on a cloudy day. PV systems produce no greenhouse gases. <\/p>\n<p><strong>What are the costs and savings?<\/strong><\/p>\n<p>You  could be saving up to 1.1 tonnes of CO2 a year and \u00a3150 &#8211; \u00a3200 off your electricity  bill (assuming the excess electricity is sold to your electricity supplier). The amount of energy each solar PV cell can  generate in full sunlight is measured as Kilowatt Peak  (kWp). For the average domestic system, costs can be around \u00a35,000- \u00a38,000 per  kWp installed, and \u00a0most domestic systems  are between 1.5 and 3 kWp. The <a href=\"\/\">Energy Saving Trust<\/a> gives more details on costs and savings.<\/p>\n<p>   <strong>Important  points<\/strong><\/p>\n<ul>\n<li>Any electricity generated that you can\u2019t use may  be able to be exported to the grid and sold back to your electricity supplier. <\/li>\n<li>You need a roof or wall that faces within 90 degrees of south, with  no other buildings or large trees overshadowing it. If the roof surface is in  shadow for parts of the day, the output of the system decreases. <\/li>\n<li>Solar panels are not light and the roof must be strong enough to  take their weight, especially if the panel is placed on top of existing tiles. <\/li>\n<li>You may require planning permission to fit a PV system,  especially in conservation areas or on listed buildings. <\/li>\n<li>If you intend to have major roof repairs carried out it may be  worth exploring PV tiles as they can offset the cost of roof tiles. <\/li>\n<li>PV systems connected to the grid require very little  maintenance, generally limited to ensuring that the panels are kept relatively  clean and that shade from trees has not become a problem. The wiring and  components of the system should however be checked regularly by a qualified  technician. <\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Solar PV (photovoltaic) uses the energy from the sun to create electricity to run appliances&hellip;<\/p>\n","protected":false},"author":6,"featured_media":20097,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-19984","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-green-energy"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Solar electricity (PV) - Palae Energy PLC<\/title>\n<meta name=\"description\" content=\"Solar PV (photovoltaic) uses the energy from the sun to create electricity to run appliances and lighting.
