We generate brighter future
Energy for the future
The planet is the real legacy that future generations will inherit. If nothing is done to reverse the current situation, we could miss our chance to limit the concentration of greenhouse gases in the atmosphere to approximately 450 parts per million of CO2 – a level that would cap rising global temperatures at 2ºC. Solar power generation, as the cleanest and most abundant renewable source, is one of the best-proven options available to reduce our impact on the climate. We believe that ours is a remarkable contribution to ensure the planet is a better place for future generations.

Environmental Contributions and Economic Benefits
Responsible and forward-thinking governments around the world are increasingly harnessing the power of the sun and embracing solar power investments and projects. We support governments in their initiatives to promote energy independence and security, and to meet energy objectives for a greener future.
Our ground-breaking solar energy projects help build stronger economies and a cleaner environment by adding renewables to the energy mix. We also make valuable contributions to education, skills training, R&D, innovation and job creation in the communities in which we work.
Solar Explained
Energy from the sun is harnessed by photovoltaic cells, otherwise known as solar cells.
Photovoltaic (PV) cells are comprised of a semiconductor material. There are three basic types of PV cells:
- Monocrystalline photovoltaic cells are cut from a single crystal of silicon and have a smooth texture. They are the most efficient production scale solar cells for absorbing sunlight and creating electricity but are also the most expensive to produce. Monocrystalline cells are rigid and must be mounted to a frame.
- Polycrystalline photovoltaic cells are the most common type of panels on the market. These cells are cut from a block of silicon and have a large number of smaller crystals with a speckled reflective appearance. They are slightly less efficient but more cost-effective than monocrystalline cells. Polycrystalline cells also need to be mounted to a rigid frame.
- Thin film photovoltaic cells are manufactured by putting a thin film of solar reactive material onto a variety of surfaces. They are the least efficient and least expensive to produce. They can be made from various materials.
The sun’s rays shine down onto panels of PV cells, otherwise known as solar panels, which begins the energy harnessing process:
- Particles of sunlight known as photons hit PV panels and are absorbed by the silicon found within the panels.
- Photons knock electrons loose from their atoms causing an electrical potential difference.
- Current flows through the panels to cancel the potential charge difference, which in turn is captured as direct current (DC) The semi-conductive properties of the silicon allow the current to flow in one direction only.
- The electricity is harnessed as DC electricity and converted by an inverter into alternating current (AC) electricity and fed into the power grid for local consumption.
