Trinidad and Tobago: The National Energy of Trinidad and Tobago has installed a Solar PV System at the – Preysal Service Station. This is the first-of-its-kind Solar Photovoltaic (PV) system.
This system includes – 320 solar panels, Inverters, Batteries, Electrical cabling/wiring, Cable trays, Charge controllers, Mounting racks for the panels, Power control units, Temperature sensors, Weather sensors.
A battery bank has been designed to provide power autonomy for 24-hrs System performance and monitoring units.
What is Solar Photovoltaic (PV) system? –
A photovoltaic (PV) system comprises one or more – solar panels combined with an inverter and the other electrical and mechanical hardware that use energy from the – Sun to generate electricity.
PV systems can vary significantly in size from a small rooftop or portable systems to large utility-scale generation plants.
How does this system work?
The light from the Sun, which is made up of packets of energy called – photons, falls onto a ‘solar panel’ and creates an electric current via a process that is called the ‘photovoltaic effect’.
Every panel produces a comparatively small amount of energy but can be joined together with the other panels to provide higher amounts of energy as a – solar array. The electricity generated from a solar panel (or array) is in the form of a direct current (DC).
Although numerous electronic devices use the DC electricity, which also includes – ones’ phone or ones’ laptop, they are designed to work using the – electrical utility grid, which provides (and needs) alternating current – (AC).
Therefore, in order for the ‘solar electricity to be useful, it must first be converted from a – DC to AC using an inverter. This ‘AC electricity’ from the inverter can then be utilized to power electronics locally or be sent to the electrical grid for use elsewhere.
