How the solar panel system works
Solar energy originates from the sun. Solar panels (also known as “PV panels”) are used to convert light from the sun, which is constituted of particles of energy called “photons”, into electricity that may be used to power electrical loads.
How can solar energy power your home?
In this part, we’ll discuss the mechanism by which households may create and consume solar energy by employing.
Usable solar electricity is created in 4 steps:
- Solar panels create DC power
- The solar inverter turns power into useable AC electricity
- The solar inverter gives electricity to the home
- Excess solar power is sent to the grid
1- Solar panels create DC power
Homes withs often have between 15 and 25 s placed on their roofs.
Each solar panel contains a string of 60 or 72 photovoltaic cells, each built out of monocrystalline or polycrystalline silicon. The solar cells are meant to catch sunlight and convert it into direct current (DC) power using the photovoltaic effect.
The quantity of solar power that is generated relies on the strength of the sunlight and the design of the solar panel. As of 2022, individual solar panels generally generate between 250 and 400 watts per under optimum circumstances.
2- The solar inverter turns power into useable AC electricity
Home appliances are intended to utilize alternating current (AC) energy, so the DC power produced by the solar cells has to be converted before it’s given to the home. This function is done by a solar inverter.
In most residences, there is a single “string” inverter installed. These string inverters often referred to as “central inverters”, receive the combined electricity from all solar panels before converting it.
However, solar inverters may also be deployed at the module level; in such circumstances, miniature microinverters are linked to each individual solar panel to accomplish the AC-to-DC conversion.
3- The solar inverter gives electricity to the house
The inverter will subsequently supply AC power at the necessary voltage (120V/240V) to your circuit board; this power is now ready to serve any electrical loads inside your property.
With grid-tied solar power systems — the most typical sort of solar system installed in houses — you may, at any moment, utilize either solar electricity, grid power, or a mix of both.
If the demands in your home are more than the power provided by the inverter, then your loads may be satisfied by a mix of sources: partially from your rooftop solar power, and partly from the electrical grid.
4- Excess solar electricity is sent to the grid
If you have solar panels installed, it’s typical to create more solar electricity than your overall electrical loads need (what your energy demands are) (what your energy needs are). When this occurs, the extra energy flows out from the house to the electric grid through your utility meter.
The utility meter will need to be a special “net meter”, which can maintain a separate record of what power you export to the grid and what you consume from the grid.
Solar panels work by absorbing sunlight with photovoltaic cells. The panels convert this sunlight into direct current (DC) energy which travels inside the house to an inverter, which in turn converts it to alternating current (AC) energy. Any excess electricity will be sent off to the electric grid, which then provides you with the electricity needed if you use more than the panels create.
