Once you’ve decided that your house is suitable for solar, you’ll need to think about what size system to install.
The factors you need to consider are:
|System size||Number of panels||Price range|
You can find some good advice about installer and components on the Whirlpool forum.
Once a solar installer gets in touch, they’ll look a few of your previous bills and figure out how many units (kWh) you use on average per day. From there, they’ll ask you a few questions about your lifestyle and family size to work out what percentage of that daily usage you use during the middle of the day.
Once they’ve figured this out they’ll suggest a system that will produce a similar amount to this or one that produces slightly more depending on anticipated growth in usage or how much power usage you can shift into the middle of the day such as washing machines and dishwashers.
From there, they’ll recommend a few sizes with different quality components depending on your budget.
Important: We recommend that you get a few different quotes so that you can tell if their numbers are overly optimistic.
