Different Photo Voltaic systems with their advantages:
Typically, grid connected PV systems are utilized purely for energy cost reduction and self-consumption of green power. Unutilised power generated by the Solsquare PV Grid-Tie system may be fed back into the utility network.
This avoids green power being lost as may be the case with an Island system, once batteries have been fully charged.
This ensures that your Solsquare PV Grid-Tied system always operates at maximum capacity, yielding the lowest possible cost of generating green power per Kw/H. Also, as result of this and the lack of battery storage, Solsquare PV Grid-Tied systems have the shortest payback periods. As these systems do not require any batteries, the required maintenance efforts are virtually negligible.
Grid-Tied systems do not offer backup in case of grid failure. Grid systems can be expanded to multi-hybrid systems at a later stage.
- Cost effective (short payback)
- Staged, modular expansion
- Easy installation
- Reduced carbon footprint
- Grid parity today
- No serious lifestyle changes
- No power storage losses
- Low maintenance
- High efficiency
How the energy of the sun is converted into electricity
The question is – how does solar work and why solar at all?
The most important provider of energy to the earth is not coal as many of us are led to believe, but is the sun – furthermore, coal is the worst fuel for carbon emissions.
Everything living is dependent on the sun for its survival as it not only gives us light but it also offers warmth and is inexhaustible in addition to being renewable, plus there is so much of it that is so readily available, especially to the continent of Africa.
The amount of solar energy that the earth receives on a daily basis is far more than the total energy that we need – as a matter of fact – almost 6 000 times more. Southern Africa is swathed in a solar resource easily available and is perhaps the highest in the world enjoying sunshine almost all year round. The solar radiance levels, particularly those in the Northern Cape and the North-West Province, which means that the strength of the solar power received can be used over and over again.
- Solar or photovoltaic cells are designed in such a manner as to capture as much of the sun’s rays as possible.
- The daylight energy from the sun is converted into electricity.
- A singular solar cell consists of two paper-thin plates that are made out of semi-conductive material such as silicon with a layer of chemicals on their surface.
- The photons are converted into electrons.
- When the sunlight falls on the cell, electrons are released from the silicon.
- They then move over the layer of chemicals which generates an electric current.
- This solar energy can be used to power most electrical appliances.
- Although these were thought to be a costly method to produce electricity, price reductions in recent years have caused solar PV generated electricity to become more accessible to the ordinary man in the street.
- Solar energy is already cheaper than using coal to produce energy.
If you are keen to cut back on your monthly electricity bill, solar is the way of the future.
Needless to say South Africa is well-placed to make use of this free and reliable source of energy which the sun has to offer.
