Flexible Hydrogenated Amorphous Silicon Solar Cells

Flexible Hydrogenated Amorphous Silicon Solar Cells

Acheiving low cost, non-toxic, high efficiency, high throughput solar cells is the ultimate challenge for the solar energy industry. Traditional glass laminate crystalline silicon solar cells offer relatively high efficiency (up to 20%) but are an expensive product....
Photovoltaics in Residential Applications

Photovoltaics in Residential Applications

Residential grid connected PV systems are relatively simple to design with easy to predict annual yields. However, the headline economics of residential PV in the UK are at present unattractive. A typical small residential PV system (1 to 3 kWp) as shown in the top...
Solar PV Systems at Highfield Campus, Southampton

Solar PV Systems at Highfield Campus, Southampton

The University of Southampton has three permanently grid connected PV systems on its Highfield Campus designed and serviced by the Sustainable Energy Research Group. The installed capacity of these three facilities is about 20 kWp: (a) George Thomas Building –...
Photovoltaic Module Mismatch Studies

Photovoltaic Module Mismatch Studies

Silicon wafer solar cells have a low working voltage (~0.5 V) and so must be connected electrically in series to become useful. A ‘standard’ PV module consists of 36 cells in series, producing a maximum power point voltage of ~18 V suitable for charging a 12 V dc...
Reliable Photovoltaic Connectors

Reliable Photovoltaic Connectors

Background Photovoltaic modules have no moving parts and last upwards of 25 years with no maintenance aside from the occasional cleaning. Realising such a long lifetime for entire PV systems relies on the continued integrity of all system components. The installation...
Keeping Food Chilled – by Solar Power

Keeping Food Chilled – by Solar Power

The Sustainable Energy Research Group has led a programme to develop what is believed to be the world’s first solar powered refrigeration unit installed on a working articulated vehicle for Sainsbury’s Supermarkets Ltd. Power for the refrigeration unit is...
