Global Responsibility For Nature And The Environment.

Solar Powered Heating, developed in the interest of safety, economical use of resources and enviromental sustainability.

A solar panel package for a hot water heating which allows the consumer to take advantage of the renewable and sustainable energy of the sun.

 

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;

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.
