Grid-tied solar is the most common system installed because the power produced from your panels is consumed first, then if you need more you can draw from the grid. When you produce more than you’re consuming, the excess is also exported to the grid. The goal is to install the right size system and align your load as much as possible to the solar output so that you minimise your imported power and maximise consumption of your solar generated power.

Through saving you money on your power bills, residential solar power systems can quickly pay for themselves and soon even bring an effective return on your setup investment.
Using NIWA’s historical data and today's average power prices, we’re able to give you an expected ROI.
These graphs show your expected return based on a 4.16kW system, saving $0.30c per kWh of grid supply.
The sooner you go solar, the greater the return ~ so why hold off on a good investment?
With the solar technology available today, it has become economically viable—and even profitable—to install solar power for many businesses and homes.
Solar Photo Voltaic (PV) systems are cost effective, easy to install and do not require resource or building consent, making them the clear contender for domestic and auxillarary commercial energy production both now and in the future.
Grid-Tied means you rely on the commercial electricity supply grid for when your solar panels are not producing, i.e. at night. Power from the panels is used during the day when they are generating, in priority over grid power. If there is not enough power generating from the solar panels, electricity from the grid is used to subsidise the load required. Surplus electricity from the panels is not stored, but is directed back into the grid.
These are the simplest system and the cheapest to set up, meaning you can see the greatest return on your investment through savings on power bills.
How it works
A solar array is mounted, usually on the roof to capture sunlight through the day time, which the solar panels turn into electrical energy.
The energy goes to an inverter which converts the power to 230V AC electricity (that’s the kind you usually use in the house) and sends it to your switchboard where you use it for all your household electrical load, just as you do normally with grid power.
When the panels are generating more than is being used, the excess electricity is sent into the grid.
During high load demand and at night when the panels are not generating, electricity from the grid is used.
The inverter controls the flow of electricity so that the power from the solar panels is always used in priority over the grid.
