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....
UK Micro Wind Trial

UK Micro Wind Trial

The UK has the best wind resource in Europe and this is now starting to be harnessed through both on-shore and off-shore multi-MW scale wind farms. Micro wind power technology, which is essentially the installation of small scale, 1-10 kW wind turbines on buildings or...
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...
Micro Wind Modelling Tool

Micro Wind Modelling Tool

Within the framework of a research project funded by the Economic & Social Research Council (ESRC) a micro wind modelling tool has been developed by SERG prompted by the imminent arrival of the technology. The tool allows the user to define a particular micro wind...
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...
