Building Efficient Solar Panels For A Solar Water Heating System

One way of making a solar water heating system is to use solar panels: these are small solar collectors, each in a waterproof, well insulated box which can be mounted anywhere convenient and connected to a hot water cylinder. Commercial solar panels have cases made of aluminium or glass fibre which will not rot or … Read more

Calculating The Energy Gained From Solar Heating

We can work out the benefits of solar heating from work carried out by several government agencies. The Building Research Establishment estimates that the average household uses 170 litres of hot water daily at a temperature of 55°C. This represents a useful energy demand of about 3350kWh per year. Another BRE estimate gives the consumption … Read more
