The use of diesel to run the turbines to keep the lights on is expensive and unsustainable, I have had numerous customers who are sitting with quotes but decided to postpone the purchase of their solar system as load shedding had abated.
Over and above the long term cost savings from generating your own electricity, the other advantages are numerous. no down time, no loss of business or productivity, security and IT systems stay alive and many more.
Rather place your order for your system, while it is quiet, when the next round of load shedding starts, the demand means that you will be at the back of the queue, you can also negotiate a better deal for yourself by being a bit more proactive!
