The Grid Explained

The grid, a phrase often thrown around by the energy companies in regard to buying off, sending to, or being more independent from, but never stopped and explained. So what exactly is the grid, and how do we actually interact with it? Lets look at some basics to help us understand what this four letter word has to do with our energy.

What is the Grid

What is referred to as ‘The Grid’ is an electrical grid connected to the network, and created to deliver electricity from the supplier to the consumer. It is how energy providers supply electricity to our homes, or businesses, for a retailed price, and what is reflected on our electricity bills.

When solar is introduced, it changes this, and the grid starts to interact differently to us dependant on if we have a gross, or net system. To break it down, gross systems operate by feeding back all the energy generated from the solar system to the grid, with the home or business owner still paying for all of their electricity they use, but being credited for all the energy they feed back. Net systems differ here by first feeding the energy they generate into the home or business for power, with any excess then feeding back to the grid, again, earning the consumer money for their contribution. Both instances allow the consumer the ability to feed energy back to the grid, which is how solar alters the usual relationship between consumer and the grid.


Now if we want to then take this further, the introduction of energy storage systems can do this by storing the excess energy generated inside the battery instead of sending it back to the grid. This energy is then able to be used during periods of bad weather, at night, or even at times of high-usage, meaning the consumer can rely more on their own solar generation. Smart home technologies can also be added onto this to help the consumer monitor how much energy they use, patterns, and behaviours, or to learn when they could sell back to the grid at times when the price is best.

Going Grid Free

Although the conversation often revolves around being less dependant on buying power off the grid, it is often suggested that homes or businesses do not go completely grid-free if they expect to continue a high level of energy consumption. Going off the grid is a lifestyle choice, with consumers needing to be certain that their energy needs can be met without the use of the grid. And this can be very beneficial to some, especially if the consumer operates in an area of constant power outages, or without need for excess energy, and SolarHub are able to assist with these, having an off-grid installer on team.

However, in saying this, for many consumers, being connected to the grid but utilising optimisational technologies, consumers are able to still become less dependant on the grid, but still have the security of being able to draw excess energy from the grid when it is needed, and their solar is not able to produce enough energy for their requirements. Either situation must be best for the home or business owner, which is where our Sales Representatives are able to step in and help by evaluating the energy requirements, usage, and ambitions of each individual, and offering personalised advice on each situation.
