How does a solar panel work step by step

Solar panels absorb clean renewable energy in the form of sunlight and convert that light into electricity which may then be utilized to supply power for electrical loads. They are formed of multiple separate solar cells which are themselves composed of layers of silicon, phosphorous (which produces the negative charge), and boron (which provides the positive charge).

Let’s take a straightforward, step-by-step look at how solar electricity works.

Step-1: Solar Panels convert sunlight to energy

Solar panels receive sunlight throughout the day which they convert to electricity via the photovoltaic effect. In basic words, solar panels feature silicon cells as the active material which when exposed to sunlight produce free electrons which travel via an electrical circuit. Read our entire explanation of how solar panels operate here.

The amount of solar panels you will need for your installation depends on a variety of factors:

  • The quantity of sunlight you get in your area
  • The angle and orientation of your roof
  • How much energy do you generally spend in winter and summer

Step-2: Solar Inverter converts from DC to AC power

The direct current (DC) power generated by the panels is then linked by electrical wire to a solar inverter which is normally positioned someplace near the switchboard. Regular equipment in a house or office requires alternating current (AC) power, therefore the solar inverter’s purpose is to convert the DC energy to AC energy. There are numerous kinds and brands of inverters and they need to be constructed to fit the size of the solar panel array.

Step-3: Switchboard distributes solar energy to house appliances

The freshly converted AC energy is then linked into the switchboard so it may be utilized as a power source. If the home also has a connection to the grid, then the house will prioritize first the use of inexpensive solar energy and if there is any more energy necessary then that may easily continue to be pulled from the grid. If the solar system is producing more than adequate energy, then the excess may be ‘exported’ back to the grid for use elsewhere on the network.

Step-4: Utility meter records

Once solar is installed the responsible merchant is obligated to replace the current meter with a bi-direction meter. The meter can then record all the electricity that is pulled to the home but also record the amount of solar energy that is exported back to the grid. Often there is a little fee for the homeowner to pay to turn over this meter. The recorded power that is sent back to the grid might receive a “feed-in tariff”

Step-5: Grid rules specify system permissions

The Distributed Network Service Provider (DNSP) is the firm that owns and manages the grid (poles and wires) in your local region. A part of your energy expenditures is paid to the DNSP as a contribution to the maintenance and operating costs of the network – albeit for residential users this is not apparent and is bundled into your power supplier bills. Each DNSP has somewhat varied laws on how much solar may be placed and if you are able to export electricity back to the grid or not.

Final Words

Solar panels are the most obvious component of a photovoltaic system but only account for about 30% of the total cost of a solar farm. Photovoltaics are used to harness renewable energy from the sun, rather than relying on fossil fuels such as coal or gas.
