The Need for Grid Access

Image
Over the years with the increase in population, the demand and needs for electrical energy has also seen an exponential growth. Since electrical power is constantly used in the daily lives of citizens , without it, life as we know it will not exist. In order to get electricity to our jobs and homes the electricity grid is used. The electricity grid is an electrical power system network made up of the electricity generating plant, the transmission lines, the substations, transformers, the distribution lines and the consumers. In Trinidad and Tobago, we have an interconnected national grid system which transports the electricity from the power plant to the consumers and is totally controlled by the Trinidad and Tobago Electricity Commission (T&TEC). T&TEC purchases electricity from independent power generators and then sells it to consumers at commercial or residential rates. It is illegal to access the electricity grid without obtaining necessary permissions from T&TEC, ...

Solar Power Day & Night

Image
You are probably wondering how is it possible to have solar power both day and night if all we have in Trinidad and Tobago is approximately 12 hours of sunlight a day. Over the years talks of renewable energy went from murmurs to whispers to full conversations as declining oil, gas and coal reserves negatively impacts the world.  In T&T, with the abundance of sunshine available, solar power seems to be the most plausible type of renewable energy for the twin island. The most popular way to generate electricity from the sun is through the use of solar panels. Solar panels also known as photovoltaic (PV) panels, which are made of photovoltaic cells that use photons from sunlight to excite electrons, causing them to move, producing electricity.  Electricity is basically a flow of charge which is carried by free flowing electrons through a conductor such as copper. Solar panels, contrary to popular belief, does not operate on the heat coming from the sun. The hotter the...
