Photovoltaic Solar Panels

Power Your Home From The Sun

A Photovoltaic Solar Panel generates electricity from capturing the suns rays and convertimg it into electricity using photocells. When an array of Solar Photovoltaic Panels are installed, the amount of electricity generated becomes quite significant and can help reduce household electricity bills.

When the sunlight hits the solar panel, a reaction is caused in the photocell and a DC electric current is created. The electricity is then converted to alternative current via an inverter to make it compatible with the electricity supply in the house.  Alternatively it can be stored as DC in a battery for use later.

Contrary to popular belief, a Photovoltaic Solar Panel system does not necessarily need bright sunlight in order to operate successfully. A correctly engineered system will continue to  generate electricity even on cloudy days.

There are five main factors that will impact how much energy a Solar PV system will generate:

  • The efficiency of the panel
  • The overall size of the PV array.
  • The latitude of the location.
  • Which direction the panels face.
  • The angle at which the panels are mounted.
  • The amount of shade that may cover the panels.

How They Work

Sunlight is made up of photons, and when it hits the semi-conductor metal of the PV panel, electrons are released; these electrons form a direct current. People have been using PV for years; your pocket calculator for example typically has a number of PV cells. العاب 365 NASA has been using and developing this technology for years, satellites and other space going bodies rely on this technology to produce the power in order to run.

A typical solar PV systems consist of three main elements:

  • an array of solar PV modules
  • an inverter(s)
  • cables, display and switchgear

The inverter is an electronic device that converts the DC electricity produced by the solar array into AC with the same voltage and frequency as the mains supply. The inverter also performs various safety functions, constantly monitoring the grid and switching off in the event of a fault or major fluctuation in mains supply. هل الربح من الانترنت حقيقي

The output of the inverter goes directly into the building’s fuse box – feeding solar electricity into the building’s conventional electricity supply which means you will not have to buy so much electricity from your electricity supplier.

The appliances in the building will use the free electricity generated from your solar PV system and any surplus power will automatically be exported into the grid so that others can buy the “green” electricity you have generated

Most solar PV systems are grid connected, which means that the electricity generated is fed directly into (and synchronised with) a building’s existing mains supply. On a sunny day, the power generated by the solar PV system reduces the amount of electricity that needs to be bought from the electricity supply company. On very sunny days, or at times when not many loads are turned on, the PV may generate more power than is needed in the building, and the surplus will be exported out into the grid.​
