Solar Photovoltaic (PV) Installation of PV systems to Our Services convert sunlight into electricity This electricity can be used on site or exported back to the grid system Solar Thermal Installation of Solar collectors to convert the radiant heat from the sun to hot water for Space and Water heating Heat Pumps Heat pumps are used to convert latent heat stored in the ground, water or air to high temperature water for space and water heating
Energy Efficient Lighting Our Services Installation Lighting schemes which are designed to reduce running costs, reduce maintenance costs and reduce heat gain in buildings Improved energy control Installation of control systems to provide more effective use of the energy provision Heat Recovery Ventilation Changing the air in buildings is a major heat loss factor By installing systems which preheat the replacement air using the exhaust is a great way of making savings.
The boring bits you can ignore PV Panels PV Cells convert sunlight into electricity The do this by absorbing the photons in sunlight which causes electrons to flow in the semiconductor which produces current flow. PV Panels are made up of a number of these cells joined together like the cells of a battery. They have normally between 60 and 72 cells and produce around 36Vdc.
The boring bits you can ignore Solar Thermal Solar Thermal Systems collect the radiant heat in sunlight and transfer this energy to the glycol mixture used in the primary transfer circuit and then on to the Hot water. The main plus of Solar Thermal is that once installed it produces hot water for no more than the cost of running a small circulation pump (<£50 p.a.)
The boring bits you can ignore Heat Pumps Heat pumps extract latent heat stored within the air, the ground and natural bodies of water and convert the relatively small changes in temperature to useful heat for Space and Water heating They use the standard compression and evaporation cycle found in our fridges and freezers
The important bits Solar PV A 4kWp PV system will generate around 3300kWh of electricity in one year The government will pay you 21p per kWh for 25 years You will use around 50% of what you generate saving 1650kWh @ 12p Your energy provider will pay you 3p for each kWh (or 5p if you go with UW)
The important bits Solar Thermal A 2.5m2 (two panel) Solar Thermal Array will generate around 55% of the Hot Water requirement for a normal three bed semi (2 adults 2 kids) It has almost zero running cost and minimal maintenance requirement Other than a dual coil cylinder or thermal store it requires no major changes to the existing system
