Solar panels are playing an increasingly important role in life. How can we improve its efficiency? Let's discuss it.
The answer for this question is, the solar product can generate electricity via the photovoltaic solar cell which consists mainly of silicon material. Actually, when a special type of silicon is stroked by the sun light, it generates usable electricity in small amount because some electrons will be freely ejected from the solar cell surface in response to the sun lights effect, thereby improving the working efficiency of the solar cell panel.
The sun light is a range of spectrum, it consists of units called photons. When these photons strike the solar cell surface, they can be absorbed by the cell or reflected by the cell. The absorbed amount of photons will be converted to electricity as described above, and the reflected amount are just a waste with no benefits. So, when solar cell manufacturer wants to increase the solar cell efficiency, he is trying to reduce reflected amount of photons, and increase the absorbed amount of photons, and nowadays there are ongoing different technologies aim to increase the solar cell efficiency, and moreover, they are developed day after day via scientists and original designer manufacturers.
Usually the vast majority of solar panels exist on the market are made of 60 solar cells, and its 1.6m height & approx. 1m width physical dimension. So, if the manufacturer has succeeded in increase efficiency of each solar cell, then the whole solar panel efficiency would have been increased obviously.
When the sun light photons strike the load cell, the electrons move from his position in the atom, and become free electrons, then they start to move through the solar panel ribbons, and this flow of electrons represent the electrical current flow. The type of electricity generated from the solar panel is DC "direct current" which move through the solar panel, junction box, and wires. In order to use such DC electricity for powering our commercial or residential equipment, like computers, air conditions, washing machine, lights, heaters, etc., we need to convert DC electricity to AC electricity "Alternating current", and this conversion is done via solar inverter.
The solar inverter can be one of 3 types: Central, or string, or micro inverter. Each type has a certain application to be perfectly used for, but all do the same main job which converting DC electricity to usable AC electricity. The inverter is an important component which we can not use the solar system without it.
