A complete off-grid system can be used; However, it must be determined how large the solar system must be to function independently and meet the requirements of the entire family. You'll also need a place to store the solar energy produced by your solar panels. For this, you will need solar power stations or solar cells. They are absolutely necessary to store off-grid solar energy.
Now, how big should the off-grid system be? Well, it depends on how much electricity your house needs, how much roof space you have available, the amount of direct sunlight the solar panels receive each day, and the type of solar panel you choose. On average, if you want your entire family to rely on solar energy, your house will need a 7 kW solar system. Keep in mind that you will find solar panels of different sizes and shapes. There are also DIY kits that you can purchase.
In addition, there are grid-connected solar systems that will connect to the grid and generate electricity when the utility grid is available. To do this, you don't have to rely on batteries or battery packs to store energy. Panel performance will now be rated under standard test conditions STC. In general, larger panels will give you higher performance. For example, if your house demand is 7 kW and you want 200 watts of solar panels, you will need at least 35 panels to meet the energy demand.
