What is the Solar Energy?
Solar energy systems, work with captured solar and conversion it to electricity.
The sun is a nuclear reactor and spreads small energy packages reaching to the world in 8.5 minutes from a distance of 150 million km. Within one hour, the photons that are sufficient to meet the energy requirement of our world for one year reach the earth.
As of May 31, 2018 Turkey’s installed electricity capacity is 87 041 MW, the total installed capacity of MW Solar Power Plants is 4,703. According to that, the share of Turkey’s installed electricity capacity of Solar Power Plants is around 5%. With the continuous development of solar energy technology and the steady decline in the costs of solar panels and other solar equipment, our ability to take advantage of the abundance of solar energy increases.
According to a report published by the International Energy Agency (IEA) in 2017, solar energy has become the fastest growing energy source of the world, by leaving behind all other sources. In the coming years, we will experience the benefits of electricity produced by solar energy in some way.
How Solar Panels Work?
When photons strike the solar cells, they cause the electrons to separate from their atoms by activating them. If the conductors are connected to the plus and minus sides of the solar cells, an electrical circuit is formed and electricity is generated if the electrons flow through such a circuit. By large number of solar cells gathering together created the solar panel, a large number of solar panels come together to form the solar energy system. The more solar modules in a solar system has, the greater the installed power of the system.
Solar Panels is Made of What Kind of Materials?
Photovoltaic solar panels (PV Panel) are composed of solar cells. Solar cells are produced from silicium material like other semiconductors. Solar cells are produced in the form of two positive and one negative two layers to produce the electric field just like the batteries.
How do Solar Modules generate energy?
PV solar modules produce DC (Direct Current) electricity. In DC current, the electrons move in one direction in an electrical circuit. In the example of a lamp connected to the battery; the electrons move from the negative lead to the positive lead of battery through the lamp.
In alternating (AC) current, electrons are pushed and pulled in the opposite direction periodically, like the engine cylinder of a car. When a magnet wire rotates just next to a magnet, the generators generate AC power. Many different sources of energy, such as gas or diesel fuel, hydroelectric, nuclear, coal, wind or solar energy can turn the bell crank of this generator.
Due to the fact that conduction to long distances is less costly with alternating current, AC is preferred to DC in electricity networks. Solar modules produce DC electricity. How do we convert DC power to AC mesh? Inverter does that.
What Does the Solar Inverter Do?
A solar inverter converts DC power to AC power generated by solar panels. In addition to converting DC energy to AC, the inverters, which are the brains of solar electrical systems, provide protection against earth leakage maintains current / voltage / generated energy and keep similar statistics and allows it to work at maximum power points (Maximum Power Point Tracking) of the solar panels.
Central and series solar inverters have been widely used in the solar industry since their beginnings. The emergence of micro – inverters and optimizer systems is one of the biggest technological developments in the solar energy industry. Micro – inverters and optimizers are responsible for some of the solar panels in solar power plant like series inverters or individual panels not the entire system like central inverters. In other words, a micro inverter or optimizer is responsible for the optimum operation and keep statistics of each panel.
How Does a Solar Energy System Work?

• First, sunlight hits the solar modules on the rooftop.
• The solar light is converted to DC current by solar panels and transferred to the solar inverter.
• Solar inverter converts DC power to AC, which you can use at home.
All of these processes proceed very quickly, easy and clean way and solar technology is developing day by day.
What if you are not at home on a sunny day and you are not using the electricity produced in the rooftop solar energy system? Also, what will happen when your rooftop solar system is unable to generate electricity during the night? Don’t worry about it. With the solar energy system, your current meter will be replaced by “reversible counter”. With this way, you will be in constant exchange with the electricity grid.
Solar electrical system connected a typical grid will generate more electrical energy at noon ,when the sun at top, then consumed at home, in this case solar energy will be supplied to the electricity grid for use elsewhere. According to the current legislation, you will be selling this solar energy to the electricity distribution company and you will receive return of this energy from this institution every month.
