Solar energy – flying to the new energy era

/in /by

Although Trump has always wanted to preserve the interests of the gold lords behind it, a simple and clear fact is that coal resources cannot keep up with the changes in the 21st century energy landscape, and even fail to meet the Trump cabinet’s renewable energy. Energy policy. The US Department of Energy recently said that solar energy has defeated coal resources in the issue of the flexibility of key infrastructure and has gradually become the focus of development.

To address emergency power issues in critical infrastructure, the US Department of Energy invested $46 million to build a solar energy storage system. They see this as the most effective means of ensuring the continued operation of critical infrastructure. At the same time, the US military intends to use renewable energy as a means of improving the energy security of its facilities to ensure the resilience of military facilities.

Recently, 216 mayors representing 50 states signed a document to support the deployment of more solar facilities. This means that utility contracts in US states will accelerate the adoption of solar installations. On the other hand, as the cost of solar panels drops rapidly, the way energy is stored becomes more and more economically attractive, enabling more governments and utilities to expand their use of solar energy.

According to the US Energy Information Administration (EIA), in the first half of this year, non-hydropower renewable energy in the United States set a new record in production and consumption. Among them, solar energy production increased the most year-on-year, with a year-on-year increase of 25.4%.

The performance of the data is satisfactory, but in terms of absolute quantity, there is still much room for development of solar power. Recall that a decade ago, solar power was negligible, even though it has been developed so far, it accounts for only 1% of global electricity generation. What will happen in the future? DNV GL recently released a report titled “Energy Transformation Outlook 2018,” which mentions that by 2050, solar energy will increase by 65 times, making it one of the world’s largest sources of energy.

The development trend of solar energy in the United States is becoming more and more obvious, and other countries are expected to continue to follow up. If all goes well, the future energy model will become more and more beautiful. It is expected that some enterprises in the solar energy industry chain will also usher in the opportunity of gold development and it is worth exploring investment opportunities.

How to maintain the drone battery

/in /by

Both the drone battery and the mobile phone battery are lithium batteries, but there is a difference between the two. Compared to cell phone batteries, drone batteries have a distinctive feature – discharge. The drone battery needs to be discharged to meet the requirements of the drone in different environments, such as aerial photography. In the case of strong winds, the battery needs to be able to make a large current discharge to compensate accordingly to ensure the position of the drone. Due to different usage requirements, the life of the drone battery is relatively short.

So in order to better maintain the maintenance of the drone battery, you can do the following

1.Not low temperature

This principle, many flying friends will ignore. In the north or high altitude areas, there will often be low temperature weather. When the battery is placed outside for a long time, its discharge performance will be greatly reduced. If it is to fly at the time of normal temperature, it will definitely cause problems. At this point, the alarm voltage should be raised (for example, the single-chip alarm voltage is adjusted to 3.8V), because the voltage drop will be very fast in the low temperature environment, and the alarm will immediately fall. In addition, the battery should be insulated. Before the take-off, the battery should be stored in a warm environment, such as inside a house, inside a car, or in an incubator. Quickly install the battery when taking off and perform the mission. Try to shorten the time to half of the normal temperature when flying at low temperatures to ensure safe flight.

2. No short circuit

This often happens during battery wire maintenance and transportation. A short circuit can directly cause the battery to ignite or explode. When it is found that the battery has been disconnected after a period of use, it is necessary to re-solder the wire. Pay special attention to the soldering iron not to touch the positive and negative terminals of the battery at the same time. In addition, in the process of transporting the battery, the best method is that each battery is separately covered with a ziplock bag and placed in an explosion-proof box to prevent the positive and negative electrodes of a certain battery from simultaneously encountering other conductive materials due to bumps and collisions during transportation. Substance short circuit.

3. But not enough

a. Use a dedicated charger. This charger can be a dedicated charger for lithium ion or lithium polymerization, which is very close. Some mobile phone chargers can be used to charge lithium polymer batteries. This will not damage the battery.

b. Accurately set the number of battery cells in the battery pack. In the first few minutes of charging, you must carefully observe the display of the charger, which will display the number of batteries in the battery pack. If you are not sure, you should not charge or use a charger that you are familiar with.

c. Fill a new lithium battery pack for the first time, check the voltage of each battery cell in the battery pack, and do the same work every 10 times for charging and discharging. This is absolutely necessary, a battery pack with an unbalanced voltage will burst when the number of batteries is properly charged. If the cell voltages in the battery pack differ by more than 0.1 volts, you should charge each battery to 4.2 volts to make them equal. If the voltage difference of the battery cells exceeds 0.1 volt after each discharge, it means that your battery has failed and should be replaced.

d. Unattended, do not charge

e. Place the charged battery and charger in a safe location.

f. Generally, there is no special explanation from the manufacturer, and the charging current should not exceed 1C. Current batteries that support high current discharges also support current charging over 1C. But it will greatly shorten the battery life, it is more cost-effective to buy 3 batteries alternately than to buy a battery and have to charge fast.

4. But put

The discharge curve of the battery shows that the voltage drops faster when the discharge starts, but the discharge drops to 3.9~3.7V, and the voltage drops not fast. However, once it drops to 3.7V, the voltage drop speed will increase. If the control is not good, it will lead to over-discharge. If it is light, it will damage the battery, but the voltage will be too low to cause the bomber. Some model friends have a battery because they have fewer batteries, so the battery is short-lived. The strategy is to fly as little as possible for one minute, and the life span will fly one more cycle. It is better to buy two more batteries, and don’t fly the battery beyond the capacity limit every time. To make full use of the battery alarm, an alarm should land as soon as possible.

5. Not full of electricity to save

A fully charged battery cannot be fully charged for more than 3 days. If it is not discharged for more than one week, some batteries will be directly bulged. Some batteries may not be drummed for a while, but after several times of full power storage, the battery may be directly scrapped. Therefore, the correct way is to recharge after receiving the mission. If the battery does not have a mission within 3 days after use, please charge the monolithic voltage to 3.80~3.90V. After charging, there is no flight for various reasons. It is also necessary to discharge the battery to 3.80~3.90V within 3 days after filling. If you do not use the battery within three months, continue to save the battery after charging and discharging it once, which will extend battery life. The battery should be stored in a cool environment. When storing the battery for a long time, it is best to put it in a sealed bag or a sealed blasting box. The recommended ambient temperature is 10~25°C, and it is dry and non-corrosive.

When you buy a drone battery, don’t blindly choose it. Consider the factors such as brand, market heat, evaluation performance, etc., and consider all aspects of factors to consider the battery that suits your drone.

Energy storage has become the key to the future development of the new energy market

New energy + energy storage, leading a new era of energy revolution!

Clean energy has ushered in a golden opportunity for development, and the energy storage market is experiencing explosive growth opportunities. According to the incomplete statistics of the Zhongguancun Energy Storage Industry Technology Alliance, by the end of 2017, the cumulative installed capacity of global energy storage projects reached 175.4 GW, with an annual growth rate of 3.9%. China’s energy storage projects put into operation have a cumulative installed capacity of 28.9 GW, an annual growth rate of 18.9%, and a growth rate of about five times that of the world.

From the current form of China’s energy supply, under the general trend of energy interconnection, the development of distributed power has become a future development trend. At the same time, this is also the key to breaking the current bottleneck of photovoltaics and wind power. In distributed power generation modes and distributed power modes such as offshore wind power, energy storage is extremely important. Combined with energy storage, we can take advantage of new energy sources such as photovoltaics. It can be said that energy storage is the basis for the future development of new energy industries such as photovoltaic power generation.

At present, energy storage is mainly used in distributed generation and microgrid energy storage systems, accounting for 56% of the total installed capacity, followed by renewable energy development. In the field of centralized renewable energy generation, energy storage is mainly used to track planned output, smooth output and participate in peak shaving and FM auxiliary services.

Two major opportunities for the future development of China’s energy storage

As a reasonable solution to solve new energy consumption, improve grid stability, and improve utilization efficiency of power distribution systems, the development of China’s energy storage industry needs to accelerate under the trend of global energy storage applications. Relying on China’s huge market capacity and scale advantages, the future development of China’s energy storage has ushered in two major opportunities.

Opportunity 1:

With the development momentum of distributed photovoltaic power generation, with the “photovoltaic + energy storage” as a breakthrough, enter the distributed power market, so that energy storage becomes the standard of distributed power plants. In this way, not only can the proportion of spontaneous use of the distributed power source be increased, but also the local energy consumption of the new energy source can be improved, the stability of the power grid can be ensured, and the power limitation problem of the new energy source can be solved. In this development, commercial-grade energy storage on the user side is a hot spot, including the energy storage of this valley fill, for energy storage or integrated energy services in industrial and commercial buildings. There are such microgrids and so on. Shengshi Sunshine Container Energy Storage Equipment is mainly for large-scale industrial and commercial, off-site power generation and grid-side energy-saving requirements for backup power and peak-filled filling. At the same time, it provides users with container-type large-scale energy storage system solutions, bringing benefits to enterprises and bringing benefits to investors. The benefits of stability provide power support for the country’s stable power development.

Opportunity 2:

It is predicted that China’s new energy vehicle market will usher in the first wave of power battery “recycling tide” in 2018. By 2020, the cumulative scrap of China’s electric vehicle power batteries will reach 170,000 tons. At that time, the use of power battery ladders will become an important opportunity for the energy storage market. With the improvement of technical and policy guidance, the use of power battery ladders is expected to further open up energy storage applications.

In any case, the energy storage market has erupted on the eve. As long as we seize the opportunity and use production, China’s energy storage market is expected to rise like photovoltaic power.

Type of photovoltaic power generation

/0 Comments/in /by

1. Independent photovoltaic power generation

Independent photovoltaic power generation is also known as off-grid photovoltaic power generation. It consists mainly of solar modules, controllers and batteries. To power an AC load, an AC inverter needs to be configured. Independent photovoltaic power plants include village power supply systems in remote areas, solar home power systems, communication signal power supplies, cathodic protection, solar street lights and other independently operating photovoltaic power generation systems.

2. Grid-connected photovoltaic power generation

Grid-connected photovoltaic power generation is directly connected to the public power grid after the DC power generated by the solar module is converted into AC power that meets the requirements of the power grid. It can be divided into grid-connected power generation systems with and without batteries.

The grid-connected power generation system with battery is schedulable, can be integrated into the grid or merged from the grid as needed, and has the function of a backup power source, which can be powered urgently when the grid is powered off. Photovoltaic grid-connected power generation systems with batteries are typically installed in residential buildings; grid-connected power generation systems without batteries do not have the functionality of schedulability and backup power, and are typically installed on larger systems.

Grid-connected photovoltaic power generation concentrates on large-scale grid-connected photovoltaic power plants, generally state-level power plants.

Advantages: It can be directly delivered to the grid, and the grid can be deployed in a unified manner to supply power to users.

Disadvantages: Power station investment is large, construction period is long, area is large, and development is not much.

Decentralized small-scale grid-connected photovoltaic power generation, especially photovoltaic building integrated photovoltaic power generation, is the mainstream of grid-connected photovoltaic power generation due to its small investment, fast construction, small floor space and strong policy support.

3. Distributed photovoltaic power generation

Distributed photovoltaic power generation systems, also known as decentralized or distributed power sources, refer to the configuration of small photovoltaic power generation systems at or near a user site to meet the needs of specific users and to support the economics of existing distribution networks.
