1 Solar water pumping- Cheaper, Cleaner, Sustainable Improving People s lives

2 Solar Energy Principals Energy emitted by the sun. Measure in watts/m 2, at standard testing conditions max solar irradiance = 1000w/m2 Converted to thermal (e.g solar water heaters) and electrical (e.g. Photovoltaic modules) energy. Energy optimised by tracking sun s E-W axis. Varies throughout day and year.

3 Solar Energy Basics Solar Energy Thermal Energy Electric Energy Solar Hot Water Systems Solar Power and Lighting Systems Solar Water Pumping Systems

5 Water Supply a Global Challenge Increased demand for natural resources Climate change Energy required to access ground water Fossil fuels are expensive Grid power often not available or not reliable

6 Our alternative The Sun Sunshine is free It will deliver for another 5 billion years Africa has plenty of it!
