Grid Connected Systems
A grid-connected solar power system is the most cost-effective and simple type of solar power system. The main components of a grid connect systems are solar panels and an inverter. Solar panels convert sunlight into DC electricity, and an inverter will turn DC electricity into usable AC electricity. A grid-connected solar power system will export excess solar power to the grid but maintain the use of regular power from the grid at night (when panels not producing power).
Things to look out for when looking at a solar system for your grid-connected home.
- How much power do you use during the day and during the evening?
- How much of your daily loads do you want to cover by solar?
- Do you want to have the ability to use your solar system when there is a power cut? If so, a battery system is needed.
- The aim is to be as self-consuming as possible to get the most out of your solar
- Exporting power back to the grid is only 8-10c/kWh. This is why you want to consume as much of your power within the house as possible before it gets exported back to the grid.
If you have a solar system with no battery storage and there is a grid power cut. Your solar system WILL NOT FUNCTION until the grid connection returns. Once it does, then your whole house will be provided power by the solar system.
If you have a solar system with battery storage and there is a grid power cut. Your solar system will engage your batteries to provide power to your essential loads like your refrigerator and freezer, but it does not include your hot water cylinder or oven until the grid power returns. Once it does, then your whole house will be provided power by the solar system.
- Not every roof is designed for solar, so you need to look at what your roof can fit vs what your power requirements are
- An import/export meter is required to allow excess power to be exported back to the grid for a credit on your power bill
- A Distributed Generation (DG) application is required to get approval to install a solar system onto the local lines network.
- The phase supply into a house can vary from – One, two or three phases. This supply type will depend on how we design your solar
Our popular Whānau Freedom package suits three to four-bedroom houses that have three or four people using 10-15kW/day. This system is still connected to the grid, so you will need batteries - but this will allow your whānau the freedom to use the energy from the sun for those months when power bills can go through the roof! Our systems come with full monitoring so you can monitor your solar production, loads and battery capacity.
Our Kōtuku Kit package is perfect if you are living with up to 5 people in a 3-4 bedroom whare. With this package, you can generate your power during the day and store any excess energy in your supplied batteries for nighttime use. Our technology allows you to be either grid-connected or off the grid.
The Stormtrooper Kit is our largest system available and is ideal for when there are five or more people living in a home, using 30-40kWh/day. This system has the ability to comfortably run a small energy-efficient fridge/freezer and washing machine and a small water pump, along with LED lightbulbs, and smaller appliances.
Korero mai, we love talking about solar
