It is often assumed that going off-grid is a great solution to South Africa’s energy crisis. While this is not untrue, it is not the only way. There are other approaches. Going off-grid may sound good. However, it can mean that you are completely cut-off.
Is a grid tied solar system worthwhile?
A grid tied solar system is also a beneficial solution. This approach can deliver the best of both worlds. Hence, if you are environmentally conscious, and seek independence, this may be for you.
Solar energy is increasing in popularity in South Africa. Due to the rising cost of electricity and unpredictable load-shedding, people are turning to renewables. Save money. Go solar.
Firstly, what is solar energy?
In short, solar energy is simply the light and heat that come from the sun. People can harness the sun’s energy in a few different ways: Photovoltaic cells, which convert sunlight into electricity is one of the most popular ways. Solar panels are installed either on your roof or on the ground to harness this power. Thereafter, it is converted to electricity.
A grid tied solar system uses this approach to harness the sun’s energy. Additionally, it is connected to the national electricity grid.
Why solar?
Solar power is a, 100% clean renewable energy source. Solar resources reduce our dependence on fossil fields. These include using coal, oil, and natural gas for electricity production. Fossil fuels produce harmful emissions that affect the quality of air, water and soil. Additionally, they contribute to global warming.
In contrast, solar energy does not produce pollution. The sun’s unlimited power is an abundant source of energy. It does not strip the landscape or affect the ozone layer. It conserves non-renewable energy sources and helps protect the environment.
Solar energy is an investment in the future of the planet. A grid tied solar system has many benefits.
What is a grid tied system?
A grid-tied solar system is connected to the electrical grid. Moreover, it requires the grid to be running for the solar system to produce energy. Therefore, it works while the sun shines. Additionally, excess energy is fed back to the grid. This increases the overall energy supply in the area.
The option of a grid tied system is becoming more popular. The available technology is also increasing.
Benefits:
- A grid tied solar system tends to be less expensive than off-grid.
- They are cost effective in the long run
- These systems do not need batteries.
- They are generally reliable
- A grid tied solar system can contribute to energy provision for a whole area
- It will decrease your overall electricity bill
- You can draw power from the grid at night
- The benefits are positive for the environment
- These systems are relatively low maintenance
- A grid tied system can be installed in various places eg on the roof / on land / on water. This depends on your property’s layout
- These systems are suitable for residential and business use
- High efficiency can be reached with the right hardware and installation
Disadvantages:
- A grid tied solar system must be big enough to feed excess energy into the grid
- They don’t generate power at night (Batteries are a solution to this)
- Municipal agreements can be lengthy to conclude if you wish to enter a buy-back agreement
Overall, the pros of a grid tied solar system outweigh the cons. There are multiple benefits for you and the whole environment. Always do your homework. Do some research. Check the options. Read the fine print. The more you know, the more informed you will be. Solar is always a good option. However, it’s up to you to make the right purchase.
