We aim to provide clients with information so that they can make informed decisions when looking at solar installations for home or business.
âGoing off the gridâ
This term is frequently misunderstood by the general public and installers alike when it comes to solar power and installations. So what does it really mean to go âOff the gridâ? It means to literally use NO Eskom electricity. You are completely disconnected from your municipal supply.
To go âoff the grid,â would mean that you require enough solar panels to generate sufficient electricity for all your electrical household needs during the day - connected to your electrical system (geysers, stoves, fridges etc.) - as well as enough solar panels to charge the backup system (batteries), so that their full capacity will be available when the sun sets. The electrical load can be reduced by using gas stoves, solar geysers and gas fridges. Keep in mind that to qualify as a âGoing off the grid system,â you still need a substantial amount of back up energy from your solar system and batteries. The backup system also needs to be big enough to supply your nightly electric demands to run all your appliances like lights etc. until solar power is available and adequate. The calculation of the number of solar panels and batteries needed, needs to take into account the different seasons and the amount of sunlight hours available. In addition to this, a generator with the right capacity is also needed for rainy or overcast days to supply electricity for all household needs when solar power is not available, or the batteries are low on energy. A few solar panels, and 2-3 batteries cannot be classified as a âGoing off the grid system,â but rather as a type of inverter systemâŠ.be informed!
