Free energy!
Many people believe that solar panels only work in the summer, however this type of free energy is available throughout the year. From May to September Grant Solar can produce 100% of the energy required for heating your domestic water (see right). The Grant Sahara collector operates not just with direct sunlight, but also diffused sunlight, so they even work on cloudy days.
On average Grant Solar can provide up to 70% of your hot water needs per year, for free!
Solar Radiation in the UK & Ireland
The diagram on the right shows the total average solar radiation falling on 1m² surface, inclined at 30° to the horizontal, measured in kilowatt-hours. The average property requires approximately 3,000 kWh per year for domestic water heating.
