Many companies sell and install solar panel systems. Always take the time to do your background research and design a solar panel comparison table. When comparing quotes from different suppliers you should check for:

• The size of the system and inverter and what will best suit your needs;
• Any surcharges (such as for difficult access or non-standard mounting of the panels);
• Whether a deposit is required;
• How long it will take to get your system installed;
• The warranty and contract conditions;
• Whether the company uses accredited designers and installers;
• Whether the solar power supplier will liaise with your distributor and retailer to ensure that you have the right type of meter and that you will receive a feed in tariff.

If you have an older type meter your distributor will need to install a new meter that will support your solar PV system. This meter may be called an interval, bi-directional or smart meter. You may be charged for a meter upgrade through the electricity bill you receive from your retailer. You can check with your retailer or distributor for information on a new meter and how much it may cost.

There are also a number of DIY solar installation kits that may offer a cheaper option when considering the initial costs of installing a solar panels system into your home or office
