Grid-tied vs Off-Grid, What is the difference?
We will try and explain this functional and financially.
Solar Power Systems, they have Pros and Cons
|Grid-Tied Solar System||VS||Off-Grid Solar Systems|
- You can feed excess power back into the grid for credit if you apply with the municipality.
- This system allows you to install a system within your budget and use grid-supplied electricity to make up the slack.
- Shortest payback time compared to off-grid solar systems. You will recover your money sooner.
- Seamless operation, you will never notice if you are running off of Eskom or solar power. No downtime.
- This is the most efficient way of using power from solar panels. at maximum, you will lose about 4% of power over the whole system.
- This system has fewer components, which means a lower likelihood of component failure.
- You don't need to consume any power from the grid.
- You can save your excess power in batteries for night use.
- Your payback time is longer compared to grid-tied solar systems, but still within reach.
- If your area has load shedding you will be unaffected.
- You can choose to upgrade your system as you go.
- If you have bad weather you can use grid-supplied electricity for that day and then switch back to solar later.
- You will consume electricity during the night.
- If Eskom electricity fails, the inverter will shut down for safety purposes.
- longer payback time.
- A Larger cost to grid-tied solar systems.
- Batteries need to be replaced after their life span ends.
- These systems usually cost more than grid-tied solar systems.
