Solar Hot Water Systems Solar panels use the power of both direct and diffused sunlight, converting the energy into heat, to produce hot water for the home. A well-sized solar panel system could provide up to 60% of your annual hot water requirements. Solar panels are designed to go with existing heating systems that use a cylinder to store hot water. Air to Water & Air to Air Heat Pumps Air source heat pumps offers a choice of two systems: air to air or air to water, both offering significant savings compared with a conventional heating system. The air source heat pumps convert the free and sustainable latent energy in the air into heat, delivering green, low-cost, energy-saving heating and hot water all year round. For every 1kW used to power the heat pumps, 3-4 kW can be produced by the heat pumps. © Website Design SOS4Biz 2010 ~ Content PT Willis Ltd  2010 Photovoltaic Systems (PV System) A photovoltaic system (or PV system) is a system which uses one or more solar panels to convert sunlight into electricity.
