Which system is best for you?
There are different types of solar systems that cater for different needs and budgets. The simplest and most cost effective is a “grid tied” system where the solar energy produced while the sun is shining is consumed to reduce electricity bills. Another option is to store some of that solar energy in batteries to use at night or when there is load-shedding – via a “hybrid” system. Finally, you can go “off-the-grid” with no reliance on the Eskom at all. Let us help you decide which option is best for you.
Grid Connected Solar Power
- Solar power is fed into your building when the sun shines.
- When there is no sun (e.g. at night or during load-shedding), you draw power from the grid.
- No battery backup included, but an existing generator can be incorporated to feed power as needed.
- This is the most cost-effective / budget-friendly option. The main benefit is a significant reduction in your electricity bill.
- Main disadvantage – no sun, no solar power.
Battery Backup – Hybrid System
- Solar panels feed energy into the building while the sun shines.
- The panels also supply power to batteries, which on full load feed the building.
- When power failure or no sun, power is drawn from batteries to feed specially selected plugs and lights.
- Automatic switch over between solar, grid and backup power.
- Length of battery backup capacity dependent on how many and type of batteries installed.
- Similar to a Hybrid system, but with a much larger backup system that runs whole building.
- May be supplemented with other energy sources like wind turbines, a generator, solar water heating, etc.
- System fully self-reliant and pulls no power from the grid.
- Highest upfront costs, but largest savings over time.
- Removes the inconvenience of municipal grid power outages and provides peace of mind.
