Solar Thermal Photovoltaics

Just in: New range of low energy (but very bright!) LED lights and floodlights. These are not to be confused with GU10 and similar multiple low power LED lamps, that are very dim. These are a single LED of up to 30W in our most powerful floodlight. See our new page here on low energy lighting for more information. New range of ground sources and air source heat pumps now available. See our heat pumps page here. New range of wind turbines up to 1kW, limited quantities for the time being. Page coming soon. Sharp 180Watt PV panels at very low prices, see here. See also our new photovoltaic installation guide, and new products related to photovoltaic installations We now have almost 12 months of carefully monitored output information from Justin Walters' installation. See here for what you can expect from a solar thermal installation in the UK Midlands. Thanks to Justin for this. Update: Justin's figures correlate with those of Simon Jackson, showing a yield of around 34.5 kWh of useable heat energy per 58mm tube per annum.
We have a no nonsense approach, meaning all our prices are clearly displayed, and that you are welcome to visit our premises to look at our products and discuss your installation. We can currently offer super-low prices on high tech evacuated tube heat pipe solar panels. These are easily the most suitable for use in the UK climate, and provide high grade heat even on cold or overcast days. Learn more about solar thermal technology on our solar overview page, or check out what we sell on our products pages.
