A Solar installation is made up of two main elements: the panels and the inverter. Residential Solar Solutions in Pakistan The Solar panels are connected to the inverter, which transforms the direct current produced by your panels into alternating current, itself connected to your electricity meter.
Your entire installation is thus connected to the common distribution network in order to be able to inject or withdraw electricity when you need it. Discover in detail the components of a Solar installation.
Basic Principles
Solar panels are made from silicon-based Solar cells. Silicon is a semiconductor; it uses the energy of photons contained in sunlight to produce direct current. This electricity is called “green” because its production does not emit greenhouse gases.
The inverter then transforms this direct current into alternating current, the current used in the electrical circuit of our homes.
Solar panels produce electricity using sunlight, not heat. They, therefore, work very well in colder regions.
Moreover, this source of energy is inexhaustible because its source is the sun. It is therefore particularly suited to our energy needs.
The Solar Panels
In the majority of cases, your installation is placed on your roof. However, there are other types of poses. Your panels are fixed on a metal structure and connected with cables. They transform the energy contained in sunlight into electricity thanks to the Solar effect that appears in the layers of silicon, the main element of the Solar cells of your panels.
The Solar inverter
The inverter, generally placed near the electrical panel, transforms the direct current produced by your panels into alternating current to allow you to power your various electrical appliances.
As this activity gives off heat, it is best to place it in a cool place like your garage or basement.
The inverter is always accompanied by a circuit breaker to protect you against the risk of electrocution.
Compensate For Production Losses
The solar panels and the inverter are the main elements that make up a Solar installation. For these elements to work optimally, it is necessary to assemble the panels in chains or connected them to an inverter. This method avoids having to connect each panel to its own inverter.
Indeed, the panel strings make it possible to send all the voltage to a single inverter. The voltage is therefore optimized. The number of panels that can be connected in the chain is determined by various factors.
The maximum power of the panel string cannot exceed a certain proportion of the maximum input power of the inverter. The maximum voltage of the string of panels cannot exceed the maximum voltage admissible by the weakest element which makes up the direct current circuit.
Shading
The panels work in sunlight, so out of shaded areas, otherwise, the intensity decreases. If a panel or part of it is shaded, the total yield of the panel decreases.
To avoid current losses, the Solar panels are installed in series, called The principle of the string of panels implies that they are all linked together and that they adapt to the production of the weakest panel.
How To Choose Your Solar Panels?
There are different types of Solar panels and different brands, each offering several models of panels. These models vary in aesthetics (black or classic panels), power (in Wp),
the dimension (lxwxh mm), of the design (e.g. half-cut), etc The choice is therefore made on the possibilities of an installation to meet your electrical consumption needs and the aesthetics that you wish to give to your installation.
