Off Grid System

Not connected to the grid.

This system operates in areas where no grid is available, or the system is not connected
to a grid. This off-grid system requires a large capacity of battery capacity to store the energy, generated by the solar array, to be used when solar energy is not available, or to provide additional capacity supplying maximum loads when required. This requires a significant investment in PV modules, Inverters, and batteries, which is not required when a grid is available. Therefore, the off-grid systems are more suitable in rural areas with little or no grid connection.

Should these grids become unstable or not available due to power outages or load shedding, these systems can become a more viable option in the future.

Advantages

Advantages:

Off-Grid Systems

9

Independant

Power can be generated without connected to a grid

9

Power is Always Available

Power is always available, provided the battery capacity is sufficient to provide back-up for the period when solar energy is not available

9

No Surges

No surges of transients will harm electrical appliances if correct type of Surge protection is used and installed on the PV array and AC Supplies

9

System Lifetime of 25 Years

System design is for 25 years, inverters can be warranted for additional years at an additional cost and Lithium Batteries for 10 years.

9

Tax Deductible

The system is tax-deductible and savings is directly related to the annual increase of Eskom – this year was 15% compare to the interest of savings account around 11% only.

Disadvantages

Disadvantage:

Off-Grid Systems

9

Large Investment

The system requires large capital investments.

9

Battery Maintenance

If lead acid batteries require lots of maintenance but for Lithium less to low maintenance is required.

9

Extra Appliances Needed

If a generator, PV Array or Grid is not available to charge the batteries, power generation is not possible during periods when no sun is available
