1. Power Saving


2. Back up

With power rate increases a part of our ever decreasing power supply, the need for reduced energy needs can be accomplished with a grid tied system. This system produces energy during daytime which is then utilized by household consumption. Care should however be taken not to overdesign the system for power fed back into the grid as a result of over production, will be lost. Most commonly used for saving and return on investment is quick.


Back up systems are becoming the most sought after application due to the load shedding programme introduced by Eskom. Batteries and a bi directional inverter are used in this configuration to supply energy in case of power failure. Batteries can be charged with grid power when it is on and thus making the initial cost lower. PV panels can be added to charge batteries in cases where grid failure would be present for longer durations.

3. Both


4. Off Grid

Both options 1 & 2 can be utilized together to save energy costs with the grid tied system and adding batteries for load shedding purposes. It can also be programmed to firstly use PV generated power, then battery power and lastly the grid for extra savings. This method should be carefully explained for you might lose back up power. This is a more costly option and return of ivestment is far reaching.


Same as option 3 but in this instance battery storage is calculated to support the whole load over a 24 hour period and not just for back up. High end good quality batteries and a bigger PV system is required for this setup and therefore it is the most expensive
