Every property and power requirement is different. Here are the three main types of solar system, explained simply — we’ll help you decide which one suits you.

Solar + utility grid
On-Grid
Your solar panels work alongside the regular electricity grid. Solar power is used first, and the grid tops up whatever your property still needs. It is the most common choice for homes and businesses with reliable grid supply.
A fully independent system. Solar panels charge batteries during the day so you have power whenever you need it, even where grid supply is unavailable or unreliable.
The best of both worlds. A hybrid system combines solar, battery storage and a grid connection, so you use solar first, store extra energy and still have backup when the power goes out.

Greater Energy Independence
