Project: Solar PV Installation

Location: Rhosneigr, Anglesey, N Wales

Date: June 2009

The The Green Electrician was approached to design and install a solar PV array on a holiday house in Anglesey, North Wales.

The site survey showed the roof to be north west orientation and clear of obstruction and shadow.  We advised as the orientation was optimum and the solar panels would be less efficient than a more southerly orientation and we provided comparison graphs and calculations to show the difference in output. The customer was keen to proceed on this basis.  We designed a 2.16kWp array of 12 Sharp solar panels to be installed on a slate roof.

The customer also purchased the Sunny Beam stand-alone meter to show instantaneous power output and daily output over the last 31 days.

“We think all holiday cottages should do the same, a roof with a solar PV panel is an investment, whilst a roof without solar panels is a wasted asset. The Green Electrician advised us on an export only tariff with Southern Electric.This gives us 28p for every unit we export, so we are making money whilst we ar not there.

In the first 7 weeks after installation we made nearly 500 kw of electricity, a third of what we expect in the year.  This means our holiday home will be self sufficient for electricity, this is good for us and good for the environment. the owner reports
