Yes, because solar only generates electricity during the day, and the amount generated is dependent on the weather, you will still need a grid electricity supply to cover your evening and additional daytime needs.
You should be aware that the solar power to the premises is not the primary source of energy:
- the solar power offsets part of the energy supplied by your energy retailer and the remainder of the energy is supplied by the grid;
- due to the nature of solar power, neither Matter nor your landlord guarantee continuous solar energy supply to the premises; and
- loss of solar power supply will not interfere with your access to grid electricity.
Simple, when the sun is shining your home will automatically use cheaper solar electricity, avoiding more expensive grid electricity.
The Matter smartbox and meters make sure you are only charged for the solar you use at the discounted price that Matter agrees with your landlord - typically 20% less than your grid rate.
The more electricity you can use during the day, for example by running your washing machine or clothes dryer, the more you’ll save. You also get access to a Matter tenant portal so you can see what you're spending on grid power and how much solar you're using.
Any solar electricity that isn’t used will be exported back to the grid – we normally share the value of the exported electricity between tenants and landlords.
And at night you’ll import electricity from the grid and be charged by your grid electricity provider as normal – it’ll just be a much smaller bill.
No, your landlord pays to install the solar system, Matter's monitoring equipment and the service subscription fee.
Obviously this doesn't come cheap so they recover their investment over 5 years or so by charging you, their tenant for the solar energy you use. So instead of using expensive grid energy during the day you can use cheaper cleaner solar energy straight from your roof at a discount to your grid rate so you see savings!
