Revised solar PV guide to improve installation standards

By Katie Anderson on February 20, 2013

After two years in the making a revised solar PV guide has recently been launched to improve the standards of solar panel installations and increase consumer confidence in the technology. 

According to Climate Change Minister Greg Barker the new guide is set to become the go to guide for solar photovoltaic installers. Barker, who made his comments at the SolarPower UK roadshow earlier this month, said the revised guide would help improve the reliability of installations and give customers increased confidence in the product.

Launched on 8th February, the ‘Guide to Installations of Solar Photovoltaics’ includes changes to the way the performance of solar panels are estimated. The solar PV guide and updated MIS 3002 standard, which will become mandatory from 7th May, means consumers will benefit from far more accurate performance estimates, which will be based on region as opposed to a single geographical location (in Sheffield) and now accurately take into consideration roof pitch and orientation.

Up until now installers have calculated the performance of a solar array by basing their estimates on the SAP calculation which is used to calculate solar PV output based on the Government’s Standard Assessment Procedure rating system used to assess a property’s energy performance.

New calculations for shading, which are more accurate, are amongst other notable changes including banning drilling into slate roof tiles and an update to the way wind uplift is calculated. Shading analysis will be more scientific; to calculate shade factor a horizon chart is supplied. As part of the quote process, installers will be required to produce a shading diagram.

Speaking to Renewable Energy Installer Magazine about the changes Martin Cotterell, founder of Sundog Energy said: “The most significant change which installers need to go away and read about is performance estimates. The previous method was based on SAP, but it was quite crude and did not take into account geographical location. We have now taken location, pitch and orientation into greater account.”

Did you know?

Earn Money via the Feed-In TarrifThe Government's Feed-In Tariff was launched on April 1st 2010 to encourage homeowners to generate their own electricity - it is split into two methods of revenue.

The Generation Tariff earns you a fixed income for every kilowatt hour of electricity you generate. And, The Export Tariff earns you income for every kilowatt hour you generate and sell back to the grid.

An average 3/4 bedroom house fitted with 2.5kw Solar PV panels and normal electricity usage would earn over £850 p/a tax free!

Add this to an approximate £145 reduction in your electricity usage and you could benefit by over £1,000 per year.
