Solar Electric Systems are Community Power Systems Ian Shearer Energy Information Services Ltd NZ Photovoltaic Association

Community Power Solutions Providing community power systems: • Needs leadership • Needs community ownership and control • Needs a long term vision for a sustainable community • Needs community financing • Needs a shift in thinking!

Community Power Solutions Community power will help: • Provide education opportunities • Improve health of community residents • Improve employment opportunities • Strengthen community institutions • Improve the environment • Reduce energy poverty in New Zealand

Solar powered electricity (PV) • PV systems are inherently community power • PV is used in rural areas and in cities • PV can be connected to the grid or stand-alone • Rural water pumping • Houses and farm buildings. • Community buildings, schools and institutions • Phones & traffic lights
