Wind energy is one of the most promising renewable energy sources in the world today. Therefore, how to increase the power generation of downstream wind turbines is one of the most important research topics in recent years. Recently, extensive experimental and numerical studies have been conducted to examine aerodynamics of wind turbines and wake interference among the multiple wind turbines. In order to gain an in-depth understanding of the basic physics of higher total power generation and better durability of wind turbines.
People have used the power of wind for thousands of years. Wind has moved boats along the Nile River, pumped water and milled grain, supported food production and much more. Today, the kinetic energy and power of natural air flows called wind are harnessed at massive scale to create electricity. A single, modern-day offshore wind turbine can generate more than 8 megawatts of energy, enough to cleanly power nearly six homes for a year. Onshore wind farms generate hundreds of megawatts, making wind energy one of the most cost-effective, clean and readily available energy sources on the planet.

The wind is a renewable energy source caused by uneven heating on the earth's surfaces by the sun. Wind power refers to converting the kinetic energy of wind into electricity. It is a kind of clean and pollution-free renewable energy, that has been used by people in the early times, mainly through windmills to pump water, grind surfaces, and so on. Using wind power to generate electricity is environmentally friendly, and the wind energy accumulation is huge.
The effect of light on the electrical properties of certain materials has been known for more than 150 years. This is called the photoelectric effect. They convert light directly into electricity. Most photovoltaic cells are made from silicon, the core element of all modern electronics. What makes silicon special is its electron arrangement: it has four of the eight possible electrons in its outermost shell. That means it forms perfect covalent bonds with four other silicon atoms to form a lattice structure.

Monday, September 13, 2021
All solar power systems work on the same basic principles. Solar panels first use the photovoltaic (PV) effect to convert solar energy or sunlight into direct current electricity. Direct current can then be stored in batteries or converted to alternating current through solar inverters to run household appliances. Depending on the type of system, excess solar energy can be fed into the grid to earn credits or stored in a variety of different battery storage systems.
Most of people know about different components of solar photovoltaic system, like solar panels, solar inverters and mounting systems. But many of them do not have much details about how to set up and install the whole rooftop solar photovoltaic plant, especially the mounting system, to extent that they may have a concern of damaging their roof in case of installing this mounting system on it.
Solar energy is an essential energy source for all life on Earth. Humans began harnessing solar energy thousands of years ago for tasks like drying food and simple heating techniques, offering numerous possibilities for enhancing daily life. Today, with advancements in science and technology, solar energy has become a critical clean and renewable resource, widely used for power generation and heating, alleviating resource consumption and environmental pressures on the planet. The core technology of solar power generation is the solar cell. A solar cell is a key device that converts solar energy into electrical energy, enabling solar power to play a broader role in modern life and industry. Home Power Inverter will delve into the principles of solar energy, the operating mechanisms of solar cells, application scenarios, and future trends to explore the relationship between solar energy and solar cells.
Solar Inverter is like any electronic device, it is built and sold based on its low price or high quality performance (high price), so the customer can take purchasing decision based on his requirements or budget. Generally, if you are not an electronic engineer, it will be difficult to know the solar inverter internal components efficiency which is the cornerstone for inverter quality and lifetime expectancy. Here, we shall provide two guides for you to indicate the good quality solar inverter even you are not a specialist in solar system inverters industry.
The solar panel is the first working part of solar photovoltaic system to converts the sun light to DC electricity. It is made of silicon element, and the silicon is abundant element on the earth, it represents approximate 30% of the earth crust, and it’s the seventh common element on the world.
Solar mounting structure is an important part of the solar system, it is used to install the solar array on our roofs, and it uses different kinds of frames, and railings. Most of mounting structure systems are made of Aluminum with stainless steel hardware, and designed to integrate with different kinds/power capacities (weights) of solar panels and to integrate as well with different types of roofs.
PV inverter or Solar inverter is one of the most critical components of the solar power system and is often referred to as the heart of a solar PV system. It converts DC (like 12V/ 24V/ 48V) electricity from solar panel into AC (like 120V/ 230V/ 240V) power required to run your applicance. Photo-Voltaic power generation system is mainly composed of solar panels (components), controllers and inverters. They are mainly composed of electronic components, but do not involve mechanical components.
After taking the decision to install your solar system, you select the most suited solar company to design the system, get the approval on solar system capacity from your electric utility, then installation is done finally. Actually it takes approx. 3 weeks in average to install your solar photo-voltaic on your roof depending on the system size, and weather conditions.
It's really an important matter to monitor the generation of the solar system, and zthe market nowadays doing such task and providing you the balance between the 2 amount of electrical energies. Monitoring equipment nowadays not only providing energy measurements, but you will be able to control both circuits as well. Also, the monitoring equipment will help you understanding your system well, so can maintain the solar photovoltaic system, and reduce your electricity consumption. The solar systems installers become offering smart monitoring system, which can do many tasks related monitoring and control. Moreover, the monitoring equipment became coming with email alert function, so can inform you when the fault happened, so you can take rapid corrective action accordingly.
The solar panels have a point on their performance curve in which they generate maximum power under a set of circumstances, and this point called (Maximum Power Point), and on the other side, the solar inverter has maximum power point tracking feature "MPPT", so it continuously searches and hunts this point to maximize the generated energy/power from your solar system. Inverter.com offers this feature for each Micro Inverter.
The sun radiation intensity varies along the day, and the solar array output varies accordingly, so the first regulation job of the inverter is to accept and regulate such change in DC electricity, trying maximize the DC energy harvest as described in aforementioned second job. Also, grid parameters like voltage, and frequency change with grid loads variation, so the second regulation job of the inverter is to regulate and synchronize all these variables, so the solar system can be connected to the grid safely within power quality specs, and with No disconnection in case of grid tie solar photo-voltaic systems. Another regulation job of the solar inverter is monitoring, and protection for both DC voltage, and AC voltage sides parameters, so it disconnects in case of faults or for safety reasons.
Solar panels are the main part in the solar system with a job to convert sun lights to DC electricity, and their costs represent a relatively considerable amount of the whole solar system price. The price of the solar panels continuously changes from year to year based on three factors.
The micro grid inverter is a small plug and play device which is usually connected to one solar panel/module to convert DC to AC electricity, and that is its mainly difference from other solar string and central inverters which can be connected to multiple solar panels. In addition, the output from several micro-inverters are always connected together to electrically feed one electrical grid panel.
Solar electricity generation system has a huge environmental benefits in avoiding carbon dioxide gas (CO2) emission, which represents significant amount releases in other conventional electricity generation source. In industrial countries, and to generate one kilo watt hour electricity from conventional energy source, an average amount of 1kg of CO2 will be released, so tones of CO2 will be emitted yearly in only one country, but in fact the actual CO2 released amount differ from one country to another and from one fuel/generation technology to another. You can imagine what will be total released amount for the whole world! And how much you save if CO2 free technology of solar electricity generation is used, it’s really great environmental benefit.
Mainly in 2 cases the solar micro inverter exhibits unique benefits; The first is when there is shading across our solar panels array, and the second is when we need our solar panels to face different directions due to our roof design. As micro solar inverter will allow every solar panel to run on its own, so if one or more solar panels are affected by shading, this will not affect the output power of our whole solar array, because other panels subjected to sunlight will still produce its maximum power capacity and will not affected by shading solar panels.
The inverter is considered as the brain of the solar system. And although there are different types of the solar inverters, but they all have the main components, let us see what are they and what are their functions as following:
1. Capacitor: It is used to filter ripples on the DC bus originated from semi-conductors switching, keep stable voltage on the DC bus, and reduce losses between the solar array and the solar inverter.
2. Monitoring Software: It used to monitor the solar system, providing the status of solar system to installer & owner, and alert them in case of faults. This software is running on inverter internal controller/processor.
3. Solid State Devices: Mainly we intend IGBTs, MOSFETs and transistor, they are used to do the inverter main job which is converting DC current to AC current.
4. Magnetic components: They include transformer and inductor to filter and smooth the AC wave shape for electrical grid connection, also they provide isolation between the DC circuit and the AC grid.
