The development of science and technology has led to the advancement of solar power generation, and solar power generation systems have also entered our lives. Looking at the foreign solar photovoltaic power generation industry, it has gradually matured, and the domestic market is also in hot condition. How far can solar power go? Sungzu made a simple analysis of the development prospects of solar power generation.

First, Solar power generation prospects – bright future

Looking at this issue from the perspective of a bystander, from a few years ago: solar power is likely to largely replace the current dominant coal-fired power station, and the current view: solar power has replaced coal. For one reason, the cause of global warming is the increase in carbon dioxide, and the characteristics of solar power generation are low-carbon and environmentally friendly, and the two are suitable combinations. Another reason is that the application of distributed solar power generation effectively improves the quality of life of people in remote areas and solves the problem that the national grid is difficult to transport electricity due to cost and technology. In remote areas, people use solar power to solve electricity problems.

Second, the prospect of solar power generation – home solar energy development has bottlenecks

There are two major points in the development of solar power:

1. The direct current generated by solar power can only be directly used for pure electric resistance appliances such as lighting and heating; if used in refrigerators, washing machines, color TVs, air conditioners, etc., household appliances need to be converted into alternating current through inverters, which can increase the investment and Operation and maintenance costs.

2. Household solar power is usually installed on the roof and the sun wall, requiring a unified design plan. Some places with poor lighting are constrained, combining the first two points, limiting the use of solar power in rural cities.

Third, the prospect of solar power generation – the problem that needs to be solved now

All technologies that can be widely used are constantly changing and innovating. Solar power generation must be widely accepted and used, and the following technical problems must be solved:

1. The first is whether it can greatly improve the conversion efficiency of solar panels. For example, the conversion efficiency of solar panels used on a large scale is increased from about 18% to about 30% under the condition of ensuring cost reduction.

2. Solve the safety problem of the power grid that the large power grid is subjected to the impact and vibration of photovoltaic power generation. Otherwise, the large grid cannot withstand the high proportion of solar photovoltaic power generation impact.

3. Significantly reduce the cost of solar power generation equipment, so that the cost per kilowatt is quite or even lower than the cost of conventional thermal power generation. At present, the cost of conventional thermal power is about 5,000 yuan per kilowatt, while the cost per kilowatt of solar photovoltaic power generation system is about 10,000 yuan. At the same time, the annual effective power generation time of conventional thermal power plants is more than 6,000 hours, and the effective power generation time of solar photovoltaic power generation systems is only 2,000 hours.

From the above analysis, it can be seen that in the long run, the future prospects of solar power generation are bright. If the photovoltaic technology problem fails to improve and adapt, it will become one of the constraints that restrict the development of solar power.

1. Preparation before purchase, that is, preliminary determination of capacity and brand

Before purchasing a mobile power supply, we must first consider a few issues and combine our own needs: specific use, location, whether a short-term emergency or long-term outing is required. If it is used for emergency charging, it is necessary to select a relatively small product, such a product is easy to carry, and can also make a call while charging, but relatively speaking, the capacity of the battery is small. If it is used for long-term outdoor use, some products with large battery capacity are needed. This product is relatively large in size and inconvenient to carry. Of course, there are some medium-sized, stylish products that may be a good choice for use on the subway or train. As for the choice of outdoor mobile power brands, I think I want to choose a brand with good quality and good image. You can go to the professional rankings to understand.

2. Try to choose brand products

The establishment of a brand requires advertising, and it needs to be passed on from word to mouth. Choosing a well-known mobile power brand, product quality may be better, and future after-sales service is in place.

3. Selection of energy storage media

The main batteries used in mobile power are nickel-metal hydride batteries, lithium iron phosphate batteries, liquid lithium-ion batteries and lithium polymer batteries. The latter two types of batteries are mainly sold in the market. You cannot choose to use the first two types of batteries. Both types of batteries have low output efficiency and do not have any advantages. Don’t buy them. Liquid lithium-ion batteries and lithium polymer batteries have relatively stable output efficiencies, especially lithium polymer batteries are lighter, safer and more efficient than liquid lithium-ion batteries.

4. Product appearance and weight

Depending on the application, it is necessary to choose different types of mobile power. Simple emergency use should choose a small mobile power supply, and the backup power supply should select a mobile power with a large capacity. For products with the same function, you should try to choose a light weight product that is easy to carry.

5. Product compatibility

There are many types of mobile phones and other electronic products. The circuit design and interface are different. The same mobile power supply is not suitable for all electronic products. Therefore, you must first understand the interface, voltage and other information required for electronic products before purchasing. If you can try to bring the counter to the test machine. Usually, the charging voltage and current of the mobile phone is 5V1A. If your phone is special, you should confirm the interface with the merchant.

6. Determine the conversion rate

The conversion rate of mobile power is very important. If the conversion rate is too low, it means that the line loss of the mobile power supply will be very large, which may cause heat or even explosion. The conversion rate can take into account the evaluation of each mobile power model. If an ad claims a conversion rate of more than 90%, it may be reported incorrectly. Typically, products with a conversion rate of about 85% are already very good.

7. Product accessories and additional features

While the main function of mobile power is charging, some additional features will bring us more benefits. For example, there are multiple charging adapters that can extend the range of use, and dual interfaces can simultaneously charge two electronic products, and LED lighting can be used in emergency situations. In addition, some mobile power supplies have a solar charging function. This is actually a chicken rib. Because many users find that solar charging is basically not enough, the time is too slow.

Is a lithium battery really more dangerous than a lead acid battery? But in fact, it’s not! Which of the lithium batteries and lead-acid batteries is safer because of the understanding of the battery and the explosion in some cases?

In terms of battery structure, the current lithium battery pack is basically packaged in 18650 batteries, and the lead-acid battery is basically a maintenance-free lead-acid battery with good sealing performance. If the internal pressure is too large and the safety valve is abnormal, the risk factors for both are basically the same.

If the battery is overcharged and internally hydrogenated, the electrolyte content of the 18650 battery is very limited and the amount of hydrogen evolved is very limited. However, for a lead-acid battery using dilute sulfuric acid as an electrolyte, if overcharge occurs, internal hydrogen evolution of the battery occurs. This phenomenon is very serious and the possibility of deflagration is greatly increased.

From a battery safety point of view, the 18650 battery is designed with a safety valve that not only relieves excessive internal pressure, but also physically disconnects the battery from external circuitry, which is equivalent to physically blocking the battery to ensure battery pair Other batteries are safe.

In addition, the lithium battery pack is usually equipped with a BMS protection board, which can accurately control the state of each battery in the battery pack and directly solve the problem of root overcharge and discharge.

In contrast, lead-acid batteries appear to lack safety protection in addition to safety valves. BMS protection is almost non-existent, and many inferior chargers cannot even fully charge and power down. Safety guarantees are far from lithium batteries.

Of course, if you use a lithium battery that is similar in price to a lead-acid battery, no one can save you in this situation.

Last but not least, if the battery structure is damaged by an accidental collision, the lead-acid battery seems to be safer than the lithium battery. However, in this type of accident, the battery material is exposed to an open environment for a long time and the explosion is not discussed.

The battery is not a bomb. The explosion is caused more by inferior products. From the perspective of battery safety redundancy design, qualified lithium batteries and lead-acid batteries can fully guarantee the safety of users without obvious safety differences. However, due to the large number of low-end small electric vehicles and scooters on the market, and most of them are poor quality lithium batteries, they are relatively more prone to accidents, which makes consumers have the illusion that lithium batteries are unsafe.
