PV Installers | Residential Case Studies



Project: Solar PV installation Malvern
Location: Worcestershire

A residential installation of ten panels was designed and installed for Malvern customers, Mr & Mrs Morgan. The 1.85kWp Sharp panel system was installed in September 2010 with an output prediction of 1623kWh for the first year.

The September 2011 readings showed a total output of 1782kWh over the year, exceeding the output prediction by just under 10%. Marketing Director, Claire Davies said: "Not all solar panels are equal. We have always believed in fitting the top branded solar PV panels - for a 25 year investment it would be short sighted do do anything less. Mr & Mrs Morgan have Sharp panels from one of the world's leading manufacturers and we are confident that they will continue to produce excellent readings long after unknown brands have started to degrade."

 “The financial return of about 10% on our investment has far exceeded our expectations.  We regret that we did not have a larger installation,”  Mr Morgan.

Anglesey herb grower, Rowena Mansfield asked The Green Electrician to install 15 high efficiency Suntech solar panels to offset electricity costs incurred in running her power hungry home-based nursery, 'Herbs from Wales'. 

 

  

“We chose The Green Electrician for their competitive pricing and professional site visit where every aspect of the installation was explained in detail. To date our system has recorded over 1155 kWhours and regular three-monthly re-imbursements have been paid into our bank account from our electricity supplier.Rowena Mansfield, Anglesey

 

It is estimated that the investment in the solar modules will have repaid itself in 10 years and thereafter the returns will exceed anything that could be achieved by investing in a bank. For more information on the herb nursery visit www.herbsfromwales.co.uk.

Project: Solar PV Installation Warwickshire
Location: Stratford-upon-Avon

James Pavitt, a member of sustainable action group, Transition Stratford, approached specialist pv installers, The Green Electrician to install a solar array on his home in central Stratford-upon-Avon. After a site survey, a design of 10 Sharp 180 Watt solar panels (1.8kWp) was installed on a south facing roof, either side of an existing solar thermal system. The photovoltaic system would incur some shading from a neighbouring house during winter, reducing the efficiency a little during December and January. 

 

James and Elizabeth, his partner, decided to install solar PV for a number of reasons, but chiefly to reduce carbon emissions. “We like to think that we are reasonably green, but even after installing solar water heating and a wood burning stove, we felt that we were still far too dependent on fossil fuels, so the next stage was to generate solar electricity ourselves,” explains James.

Solar PV Integrated System

As part of a re-roofing project, The Green Electrician was asked to design and install an integrated solar pv system on a private house in Bolton.  We discussed the project with the customer and worked with the roofers to coordinate the project.

 

Once the roofers had completed to membrane and batten stage, our installation team installed the 2.52 pv system.  The roofers then completed the roof, tiling around the system.

Benson PV installation Oxfordshire

The Green Electrician designed and installed a solar PV system on this private house Oxfordshire. After conducting a site survey and talking to the customer, we designed a 1.8kWp photovoltaic system, an array of 10 Sharp 180 solar panels to be installed on a single storey tile roof.  The customer also purchased the Sunny Beam stand-alone meter to show instantaneous power output and daily output over the last 31 days.

 

The system exceeded its estimated annual output of 1240kW hours in the first year.

 

 

"One advantage of installing the system is that it has made us much more conscious of electricity usage and hence has reduced our overall consumption signigicantly," the owner reports.  "Looking at the price difference between cost and selling, I am expecting very low bills for this year."

  Lower Brailes PV installation

The Green Electrician was asked to install a domestic array of PV solar panels to generate enough electricity to supply 100% of the family’s electricity requirements.

 

Located in a Conservation Area, the owners contacted the Planning Office and were advised that planning permission was not required, as it came under the 'Town and Country Planning (General Permitted Development) (Amendment) (England) Order 2008'.  The property is 150 years old, with a new roof dating back 30 years.

 

The site survey showed the roof of slate with a southwest orientation, with slight shading during summer. Maximising the roof space, we were able to design a system of 16 Sanyo hybrid panels, to produce an estimated 2,800 kWh/year, enough to cover annual electricity requirements. The Sanyo hybrid panels were chosen for their efficiency. Whilst more expensive than standard panels, their output is higher.

 

The homeowners benefited from a grant from the Low Carbon Buildings Programme and are eligible for the new Feed-in Tariff (36.5p/unit generated). The grant programme finishes in April 2010.

"We are now self sufficient in electricity, which was our target.We have been monitoring our meter and our record so far is 16.5 units in one day. Very promising!"  said homeowner Jo Taylor.

holiday house solar pvThe
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 owner reports

In the first year of installation, the system made 35 kWh over the estimated annual output. In June it averaged 11kWh/day. This demonstrates how close the Government SAP figures are in estimating the annual output of a solar electric system.

“I was surprised by how easy the installation process was.  It was smooth, easy and hassle free. My thanks go to The Green Electrician for a highly professional job on both occasions.”

Michael Jones

We were approached to design and install a solar PV array on the stable block of a small-holding in Shropshire.  We were asked to install a second array three months later on the house roof.

Our initial site survey confirmed both locations were suitable, in direction, pitch and roof structure.  Both installations were completed in the agreed timescales.  An import export metre was also fitted to enable the customer to keep track of how much energy is being produced and sold back to the grid at any time.

The two systems have a combined output of 1.96kWp with an energy output of 1,700kWh/year to be used to offset current electricity bills with surplus sold back to the grid and extra revenue in the sale of ROCS.
