More Benefits of Solar

Saves an average of 2400kWh/year/house electricity

Saves $350 - $400 per year at current electricity prices

Prevents CO2 emissions of almost 30 tonnes each house, life of system (0.6kg/kWh)

4 m2 flat plate collector with horizontal tank

Case Study

Family of four in three bedroom house in Nelson:

– Total system cost = $5200 (incl GST) includes building consents and installation

– Marginal cost = $3300 (hot water cylinder = $1900)

– Save 3000kWh/year electricity– Save $360/year (marginal cost of

electricity = 12 c/kWh)– Simple payback = 9.2 years

Solar Water Heating on New Buildings

Building Act 2004 - Greater consideration of renewable energy and energy efficiency in new

buildings

Building Code - Must respond to the Act– Minimum home energy performance standards – Solar water heating may be one ‘acceptable solution’

to meeting requirements of Act.
