Maximum Power Point Tracking (MPPT) is a new technology, which is an upgraded product of the traditional solar charge and discharge controller. Principle of MPPT To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery. If the voltage of the solar panel is lower than the voltage of the battery, the output current will be close to zero. Therefore, for safety reasons, when solar panels are manufactured, the peak voltage (Vpp) of solar panels is about 17V, which is set according to the standard when the ambient temperature is 25°C. When the weather is very hot, the peak voltage Vpp of the solar panel will drop to about 15V, but in cold weather, the peak voltage Vpp of the solar energy can reach 18V. Let's go back and compare the difference between the MPPT solar controller and the traditional solar controller. The traditional solar charge and discharge controller is a bit like a manual gearbox. When the engine speed increases...

What is energy efficiency? We define it as using less energy—and therefore paying less money—to achieve the same level of comfort in the home. It uses less and less, and now this means using technology as much as possible, because it changes your behavior and uses less energy. Using energy and water more efficiently can not only reduce your monthly utility bills, but also reduce the load on our power grid and water supply system, and help protect the environment. Home solar power systems are also one of the ways to save energy. 1. Kitchen If you buy an electric oven on the market, look for an electric oven with an induction cooktop, which usually consumes about 30% less energy than standard coils. If you like hot drinks, please buy an electric kettle to boil water faster and more efficiently. When cooking, make sure to follow energy-saving tips, such as using appropriately sized cookware for the burner and the most energy-efficient appliances you have (such as a microwave or toaster i...

Solar energy system is not a product of modern times. As early as the seventh century BC, people discovered and used solar energy. After the first discovery in 7 BC , the Greeks and Romans quickly adopted the ability to use the sun's rays to make fires, and could do anything from lighting a torch to lighting a wooden boat as a combat exercise. Later, China also began to use these Greco-Roman "burning mirrors" to light fires. The sun room was invented in ancient times to capture solar energy to obtain its natural warmth. These normally south-facing rooms capture and concentrate sunlight from the famous Roman bathroom to Native American adobe and are still popular in many modern homes today. A legend in the history of the Greek sun is that the scientist Archimedes set fire to the wooden ship of the Roman Empire. Legend has it that he used a bronze shield to reflect the light energy of the sun, concentrating the light and attacking enemies before they landed. This has been ...

 A complete home off-grid solar system is a system with all the necessary equipment to generate, store and supply solar energy in the field. Because off-grid solar systems do not require any external power to operate, they are also known as "independent solar systems". Next, this blog will show you the steps to install a home off-grid solar system. 1. Calculate the total power demand Start by listing all the devices you plan to use and the number of hours you will use each device. This allows you to calculate the power consumption of each device, as well as the total power consumption for the day. Knowing how many kilowatt hours a day will be used, you can determine the size of your solar panel array and solar cell storage. 2. Select the battery storage capacity according to the load Next, you need to decide how much energy you want to store. Do you want to cover your day's usage, or do you want additional backup capacity? When it comes to solar backup, the rule is usuall...

With the progress of society, we need more and more electricity. When the weather becomes extremely cold or hot, the energy consumption of household appliances or the company's electricity bill becomes very expensive. So solar energy as an alternative energy source emerged. To use solar energy, you need to install a  home solar power system . In the past few years, residential solar panels have gained a lot of power and popularity. In fact, they can benefit you in many ways. For example, did you know that using a residential solar panel system can actually reduce or eliminate your electricity bill altogether? This is because solar panels use a set of solar cells or photovoltaic units to capture solar energy and convert it into electricity or gas. They are designed to withstand extreme weather conditions, so you never have to worry about unobstructed power outages. Benefits of installing a home solar system: 1. Cost savings One of the main reasons many homeowners choose home solar ...

Green and environmentally friendly solar systems are currently widely used in various fields, bringing us electricity. The  home solar system  can bring electricity to the family and save costs. The  portable solar system  allows us to be outdoors, which can bring power to the mobile phone during the day without being in the dark at night. I believe we will all be curious about the solar panels in the solar system. How the solar panels are made, we have summarized the secrets of making solar panels into 8 easy-to-understand steps! Step 1: Collect the silicon-rock in its original form. The main component of solar panels is silicon. It is a material used in various electronic products. Solar panels require the purest silicon, which is found in quartzite and quartzite gravel or sand. The raw materials are mainly from large quarries. Step 2: Melt and purify the silica Quartzite melts at high temperatures up to 2000°C. Sparks are emitted violently and must be handled with...

  Governments around the world have implemented a variety of incentive policies to promote the development and application of solar energy and other renewable energy. Among them, solar energy is considered to be a promising energy source. Generally speaking, solar power generation systems are mainly divided into two types, one is centralized, such as large-scale northwest ground photovoltaic power generation system; the other is distributed, such as industrial and commercial enterprise factory roof pv power generation system. Below, we briefly introduce several different basic types of ground photovoltaic power generation systems. 1.Independent and strip concrete foundation Advantages: Independent and strip concrete foundation adopts reinforced extended foundation, simple construction method, strong geological adaptability, foundation embedded depth can be relatively shallow. Disadvantages: Large amount of independent and strip concrete foundation works, more manpower required, lar...
