Solar panels buying guide

05.Checklist and more info

Checklist

Before buying a solar panel:

• Improving the energy efficiency of your home can save you up to 30% on your bills – turning off appliances, using the dishwasher when full and purchasing energy-efficiency appliances.
• Check if the roof faces the right direction. Only north-facing panels will produce their full capacity.
• Find out what local council approval is needed. Increasingly, local councils also have advisors that can assist you with making the best decisions on solar.
• Determine what energy reduction you would like to achieve. Assess what energy you currently use and the capacity panel you need (and can afford).
• Do the sums to estimate the system’s payback time and the environmental difference it will make. See Weighing up the costs.
• Identify various providers/installers available. Seek quotes. Make sure the installer is accredited and that the panel meets the international standards. See choosing the panel/installer.
