An off-grid power system is one that isn't connected to any electricity grid. This means that it needs to have battery storage of some sort. It is often used in rural areas that do not have grids near them. While these are more expensive than on-grid options, they're cheaper than others.
HOW DOES IT WORK?
Your solar panels are either a DC or AC coupled system. DC systems tend to be used for off-grid systems more than on-grid options. AC systems send the energy to appliances first then store it in a battery. All systems are equipped with a backup generator.
Hybrid systems are similar to off-grid systems, but hybrid systems don't have a diesel-powered backup generator, making them cheaper. Likewise, with this system, you will be hooked up to the grid, so if you have excess energy, you'll give it to the grid. If not, you'll get it from the grid.
WHY CONNECT IT?
At iSolarNT, we can do either off-grid or hybrid systems. Hybrid systems have an added benefit of getting return money from sending excess energy to the grid. In addition, any type of solar energy system also increases your property's value in Greater Darwin.
