The energy metering system is an important component in our solar system, because it tells us how much electricity our solar system generates, how much electricity our electrical appliances and equipment are using and the amount of electricity we are still buying for the power utility or export to the power utility after connecting our solar system to the power grid.

There are many different solar photo-voltaic monitoring systems in the market, and the basic element which doing such monitoring is the solar inverter itself. So, the solar inverter usually comes with some monitoring levels starting from simple convenient level to sophisticated level.

The solar inverter is the main crucial part of our solar photovoltaic system, so we have to take care about all details related to it, like mainly choosing the high quality brand when purchasing, and proper technical installation, etc. One of the important details is: Should we install it inside or outside the home? Where we should install it in our home? And what is the best place?

Actually there are three main types of solar panel in the market, and they differ between each other mainly in 3 parameters: Efficiency, capability to withstand high environment temperature, and capability to deal with diffused sun light.

After installing our new solar photovoltaic system, our electricity consumption from the electric grid may be changed, resulting in new / modified electricity consumption pattern. Also, as a result we may be subjected to a new metering regulations according to our country rules. The question is: Will there be a tariff change due to our new solar system installation? The answer for this question will be provided by your electricity retailer. Moreover, we have to get the answer for this question even before installing our solar panel power inverter, so we can weigh up the dis-advantages and advantages of the new installation before making our decision.

When Solar System company/installer design our solar photo-voltaic array, they specify two standard slopes: The first is the orientation which means the solar panels face direction, whether it will be to North, South, East or West, and the second is tilt angle which means the solar panel angel with horizontal surface "roof angle". Ideally, solar panels should face the south, and the tilt angle should equal to the solar system location latitude, so we can get maximum electricity production from our solar phot-voltaic system.

In grid tie solar photovoltaic system in which the solar inverter output is connected to the AC power grid, there are 2 ways of electrical energy metering scheme: gross metering and net metering. And here we shall discuss the difference in between.

The solar panel efficiency is the ability of the panel to convert sunlight power to usable electrical power, for example, if the solar panel efficiency is 16%, that means only 16% of the sun light hits the panel will be converted to usable electricity. Actually in the market, the average solar panels efficiency ratings vary in the range 15% up to 20%.

We can confirm that solar panel size will be indicated based on the solar system application available space installation area, as if you have a small area in which you will install the solar system, then small size solar panel with high efficiency will be considered which will cost a bit higher, but for large areas, we can sacrifice with the high efficiency factor, and buy larger size solar panel with lower efficiency and of course it will be price cheaper.

There are many advantages of micro inverter over central inverter, the first advantage is that micro inverter is performing much better in case of shading, as if there will be a partial shading on a part of our solar system due to chimneys or trees, the overall output power of the string will not be affected, but only the shaded solar panel output power will be affected, while in central inverter the overall output power of the string will be affected, and there will be much power loss. The second advantage is the capability of micro inverter to track maximum power point for each connected solar panel, resulting in high efficiency and output power from the solar system.

Monitoring the solar Photo-Voltaic system is a very important matter because it shows you how much electricity saving you got from your solar system, in addition, it assists you knowing if the system is running properly producing its rated power or it may have a fault, so you can take a rapid troubleshooting action.

A wind turbine is a mechanical device that uses the kinetic energy of the wind to generate electricity, mainly for commercial use. Wind turbine technology is one of the most reliable and cost-effective technologies for generating large amounts of electricity. It is a clean energy source that uses wind power without producing harmful gases. Windmill is one of the earliest and most efficient forms of man-made electricity. It uses wind power to generate electricity and uses it for many functions such as pumping water, sawing wood, grinding grain, etc.

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, has been used by people in the early time, mainly through the windmill to pump water, grinding surface 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.

Zero waste and no pollution: concepts that run the world today. Everyone is trying to make the world greener and cleaner. To achieve everyone's vision, switching from fossil fuels to renewables like solar energy is a must. Solar power system is important for us. In the process, 1000W portable solar power generator plays a vital role. Especially when it comes to buying solar panels and consuming solar energy, there are multiple advantages of being affordable and inexhaustible. However, without proper cleaning procedures, it is impossible to enjoy the benefits of solar energy and its equipment. Solar panel cleaning is an important part of solar power generation. Without it, photovoltaic systems will not operate efficiently, thus shortening the product life cycle.

As we all know, the current urban landscape is seriously polluted. In addition, the amount of natural resources is drying up. Although it is considered that sustainable resources in the world today are better than exhausted resources, the current resources are still insufficient to meet the necessary quotas of the entire society. Like sun, water, and wind into energy to solve this problem. To convert and make good use of solar energy, the “Solar Combiner box” has been invented.

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.
