Net Metering is one of the dominant arrangements the electricity company dealing us in billing when we install our new solar photovoltaic system. Under this arrangement, the electricity generated from the solar inverters and the solar photovoltaic system will go to feed our home (electrical loads) at first, and then the additional excess generated electricity which is not required by our home electrical appliances/loads will be exported to the power grid.
In some kind of solar photo voltaic system called Off Grid system, your solar system will incorporate batteries that can feed your loads with electricity in case of low sun radiation and night time. But such batteries add a significant cost to your solar system, so it is usually recommended to be used in remote areas in where there is No regular electricity supply exists.
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.
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.
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.
Why Clean Up Solar Panels?
Monday, September 27, 2021
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.
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.
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.
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.
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 second main benefit of the solar system is reducing or even eliminating our electricity bill, which goes up by time passing, and nowadays in most of countries it constituted as considerable amount to be paid by the customers. Moreover, and if our solar system is large enough, we will get paid from the electric utility for surplus electricity we shall export to the electric network (considering your solar system is connected to the grid, and it generates electricity more than you will use).
In general, the amount of sunlight a solar panel receives in a day is expressed in terms of peak solar hours. It means how many hours of rated power the solar panel can deliver on an average day. For example, if we have a solar panel rated at 450W and the site has 4 hours of peak sunlight, this means that we can supply this solar panel with about 4 x 450 = 1800W hour of energy per day, or 1.8kWh.This is because the amount of electricity a solar panel can produce is directly proportional to the amount of solar energy it receives, so it is important that our solar panel is installed in a direction that collects most of the direct sunlight.
First Phenomena: Its yellow and brown colors appear internally in the solar panel. Due to solar panel poor manufacturer understanding of material science, there will be unusual chemical reactions happened internally and cause the rear white plastic to turn to brown or yellow, also, this may happen to solar cells surface due to chemical reactions between silicon cell surface and chemicals used to treat the solar panel glass.
Solar panels like any other product are Not the same, as some solar panels manufacturers use the high quality equipment and materials in manufacturing process, while others do Not. The used high quality materials will lead to high solar panels performance and high reliability. Those solar products manufacturers who always conduct researches to develop their solar panels manufacturing process are absolutely the best for us to buy from even their prices may be a bit higher than others.
Those are 3 important components in any solar panel with high influence on solar panel quality, performance and life span. So, let us show their effects and how can we choose the best characteristics as following:
