A Solar Photovoltaic (PV) cell is an electronic device that produces electricity when light falls on it. As the light absorbed by the PV cell it free's up electrons present in the cell. As the electrons move from the cell, they carry an electrical charge. This is sent to a load RE: A Calculator or to a battery.

A Single PV cell can only absorb a small amount of light at a time. Consequently several cells are usually interconnected to form modules to provide larger amounts of electricity. Groups of modules can be mounted together to form a panel. Panels can be interconnected to form a photovoltaic array; these vary in electrical power from a few watts to several thousands. These systems can last a long time with a expected life span of at least 25 years.

PV panels and arrays are becoming increasingly popular and are being deployed around the world. Systems are also being integrated into existing buildings by replacing the traditional materials of the roof and facades. Building with PV panels which generate more electricity than they use can sell back the surplus to the national grid.

Advantages Of Photovoltaics

• It is a renewable resource
• The Light and energy from the sun is free. In other words, once you have your solar panels installed there are no running costs.
• Solar cells require very little maintenance because there are no moving parts.
• Production of DC current means battery storage is simple.
• PV Cells are totally silient and non-polluting.
• Solar Panels can easily be installed on roofs which means no new space is needed and each user can quietly generate their own energy.

Paynes Service

• We design the system for a given roof space or from a target for electricity generation.
• We deliver the solar panels and required accessories.
• We install, connect and commision the system.

Worcester Greenskies FK240 Solar Panels

Worcester Greenskies FK240 Solar Panels harness the power in both direct and diffused sunlight and convert the energy to heat for the production of hot water for the home.

The solar panels have been designed as a complement to existing heating systems which use a store of hot water in a cylinder.

The existing cylinder is exchanged for a cylinder with two heat exchanger coils; one from the boiler in the property and a second from the solar panels.

Greenskies FK240 Solar Panels Features Benefits Efficient collector with 92% absorption rate. Increases performance of panel. Robust panel design. Minimises risk of damamge and prelongs service life. Enviromentally friendly. All materials recyclable, enviromentally conscious manufacture. Quick Fitting. Labour and money saving. Easy to fit Reduces complexity of installation.(less labour costs) Simple to use controller. Allows quick setting of functions. Selective coating on absorber. Increases collector performance even on cloudy days. Strong solar glass cover Protects collector from damage.

The Worcester Greenskies FK240 Solar Panels are an ideal partner for condensing regular and systems boilers, with boilers running off oil or gas and a cylinder for the storage of hot water. When used together a boiler such as a Worcester Greenstar with solar system provides a highly efficient system to give heating and hot water comfort with 50% less fuel usage thoroughout the year!! A typical well sized solar system should provide around 50% of the domestic hot water requirements of a home, representing a very worthwhile saving on hot water heating costs. The remaining hot water requirement is provided by the boiler.   Principle of operation

Solar Radiation In The British Isles A common question about solar in the UK focuses on whether there is enough sunshine available to make solar worthwhile. The usual idea of British weather is of cloudy skies and intermittant sunshine. Worcester solar panels have been developed with this typical weather in mind and make the most of both direct and diffused sunlight to give a useful annual contribution wherever you are in the UK. Contrary to popular belief the amount of solar radiation recieved by the UK is enough for solar water heating to be viable supplement to existing domestic water heating. Perhaps surprisingly the UK recieves 65% of the amount of solar radiation that is recieved in the south of Spain. The raditation in the UK is made up of direct radiation on sunny days, which accounts for 40%, and diffused radiation on cloudy days, accounting for 60% of the total. Summer will provide the largest amount of radiation over the year but a useful contribution will be provided by other seasons. As an Indication, a well sized typical installation will provide the following proportion of the household domestic hot water requirement; Season % Of Requirements Fulfilled By Solar Summer 80 - 90% Spring & Autumn 40 - 50% Winter 20 - 30% This translates to roughly half of the typical annual domestic hot water requirement.
Controls The Worcester solar package includes a simple controller (TDS10) which allows the user to select the temperature required at the hot water cylinder. The controller then automatically decides when to run the pump to bring the energy from the panels to the cylinder. The control uses a simple temperature difference to define when the pump runs. The temperature in the panel must be 8 degrees higher than the store for the pump to start running. This will continue until the panel temperature gets to 4 degrees above the store and then the pump will stop. This ensures that the pump is only running when the benefit from the solar panel is available.
