Solar PV cells convert sunlight directly into electricity using semiconducting materials. A single cell can provide only a very small amount of power, but multiple cells can be connected together and fixed in a frame to form a PV module.
The modules can then be connected in series to form a string, and several strings can be joined together to form an array capable of producing scalable amounts of power.
Before the power can be exported to the electricity grid it needs to be converted from DC to AC. This is done using an Inverter which is similar in size and appearance to a small shipping container.
The final stage is to step up the voltage using a transformer to match the voltage at the distribution or transmission system point of connection.
Solar PV is an environmentally sustainable option for productive use of the land. The phosphogypsum is a waste by-product of fertiliser production that is managed by storing in large piles known as "stacks," that are sealed with a thick clay cap. The solar project has been shown not to impact the existing environmental management plan in place, with no significant site disturbance.
The project would also provide green infrastructure and energy-efficient community design and site planning for an existing brownfield site.
