How to save R881 176.81 and contribute to the planet!
Consider the facts that:
- the price of electricity per kWh will increase year on year
- installing Solar Power effectively locks you in to a fixed price per kWh for the life of the system
Then take your calculator out and apply a conservative annual price increase from Eskom of 8.5% over 20 years. If you are currently paying R1.70 per kWH that means in year 20 you will pay R8.69 per kWh.
Assume that an average family consumes 1000 units per month.
They install Grid Tie Solar only and enough to cover their annual electricity consumption. Greenpeace estimates that the cost of solar generated power is 0.79c per kWh which equates to a 20 year cost of the solar installation (in our scenario) of R186 900.00.
Whereas the family that continues to pay Eskoms inflation linked prices will pay R1 070 776.81 over 20 years (conservatively)
Greenpeace had the following to say in an article titled: Major Renewable Energy Myth Busted:
Not only is renewable energy delivering on time and within budget, it is increasingly also doing so at a much lower price than coal based electricity. In the latest bidding round, the price of wind power had dropped to 62c/kWh while solar power came in at 79c/kWh. Compare this to the predicted cost of electricity from Medupi which is currently 128c/kWh, and it is clear that renewable energy is a much better choice. The economic case for renewable energy is clear and now, based on independent research, it is becoming increasingly clear that the traditional arguments against renewable energy are unfounded. South Africa has some of the best renewable resources in the world, and renewable energy is the clear solution to the current electricity crisis, the time to act is now.
Wind and solar power are currently feeding into the energy grid within South Africa and are doing so on time and within budget. Independent Power Producers have effectively produced 4 322MW of renewable energy for inclusion into the grid in four years. To put this in perspective, Medupi (when it eventually comes online) will produce 4 764MW of electricity. The Department of Energy is quick to laud the private renewable energy program as being first class, and this program is applauded in the Global community. However, barriers to renewable energy uptake in South Africa still exist, and to truly achieve the potential from wind and solar resources these barriers to renewable energy need to be removed. Essentially, this would involve removing all the remaining barriers to rooftop solar, and expanding renewable energy projects along with implementing much more ambitious renewable energy targets.
