Will it be the flagship product of the electric motorcycle & scooter market?

Image
In 2016, the global electric motorcyclist and scooter market is valued at about USD 13 billion it's also expected to grow by about 6.9% each year and reach $ 22 billion in 2025, nearly double the growth rate Electric scooters are only popular in Korea, but major scooters and motorcycle manufacturers around the world are pushing for a market expansion in 2018 with the introduction of new products The electric scooter market accounts for 70-80% of global consumption in Southeast Asia including China It is still a low-cost market using low-performance low-cost batteries However, demand for high-performance scooters is increasing due to the drop in lithium-ion battery prices and the economic growth of Southeast Asian countries including China. Therefore, products equipped with high-performance lithium-ion batteries will be launched in earnest from next year These are the ones that can run more than 100 km in one charge In addition to Chinese manufacturers, Japanese an

How many years can solar panels be used for 25 or 50 years? & How to Repair a Broken Solar Panel

Image
solar panels are usually guaranteed by the manufacturer for 80% performance for 25 years according to a report from the US NREL, the performance of solar panels varies from 0.3 to 0.9% per year silicon-based solar panels have the lowest performance degradation, and thin-film solar panels have a relatively high performance degradation so if you manage well, you can use it for at least 25 or even 50 years special cases, but the solar panels that have been in production for over 60 years are now working If you do not take the performance down, you can use it until it is actually damaged Silicon-based solar panels are protected by transparent tempered glass of front side and Al frame of side therefore, it can withstand a sufficient external impact, but it is not universal, so it is sometimes damaged by impact If the solar panel is damaged, most of the front glass will break continue to use this front side glass broken solar panels? solar panels are electrical products used o

China to cut 15% of PV solar FiT subsidy by 2018

Image
The Chinese government's National Development and Reform Commission (NDRC) says it will reduce its PV solar FiT subsidy by about 15% in 2018 China is divided into three regions according to the solar resources, and in the case of large-scale solar power plants, the subsidies according to the regions no 1 area is CNY0.55/Kw(USD 0.0825), no 2 area is CNY0.65/Kw(USD 0.0975) & no 3 area is CNY 0.75/Kw(USD 0.1125) Rural solar FiT subsidies, which aim to offset the income disparity between urban and rural areas, will maintain CNY0.42/Kw same as this year By the third quarter of this year, the PV solar plant installed in China will be about 43 Gwh, which will reach 54Gwh by the end of the year this is an increase of nearly 50% compared to the installation of 34.5Gwh solar power plant in 2016 The total cumulative facility capacity is expected to reach 77.8 Gwh by 2016, and 132.3 Gwh by adding 54 Gwh in 2017 The new subsidy rate announced this time will apply from Januar

Which brand solar panel is the world's most efficient?

Image
What kind of company is the world's most efficient solar cell solar panel to date? first of all, the best known three companies are candidates LG of Korea, Sunpower of USA Panasonic of Japan all three companies are producing products that exceed 20% of the panel standard LG Sunpower have similar technological backgrounds, they use N type cell and remove the bus bar from the front side of module with back contact Panasonic uses a unique technology called HIT, a so-called "Hetero junction" technology that uses crystalline solar cells and a-Si thin film solar cell technology combined But there are no champions in the three company champion is a small and medium-sized solar panel manufacturer in the United States this company made solar cells with the same technology as Panasonic, and they applied the soldering technology called "Smart Wire System" It uses a very fine wire system, similar to the multi-wire systems used in the LG neon2. It can be solder

mini solar power plant in Seoul, Korea

Image
Seoul is a big city where about 10 million people live Last year, the electricity used by Seoul City in 2016 was about 46TW most of these electricity are developed at rural power plants in addition to Seoul, and then are transmitted to Seoul via ultra-high voltage grid nuclear power plants account for about 30% of total power production in Korea Seoul's electricity self-sufficiency rate is less than 5% more nuclear power plants and more coal power plants are needed to cover the growing power consumption The grid of electrical power supply will also become larger and require more higher voltage for more efficient transmission we need this change now, even if it's a small change. Seoul Citizens If someone wants to install a mini solar power plant in their house window, the Seoul Metropolitan Government subsidizes up to 70% of the total amount so far, about 30,000 houses have installed mini solar systems over the next five years, a mini solar power plan

unveil Korea's net zero house, we called EZ House

Image
Energy-consuming zero-house demonstration complex was completed in Seoul last Thursday In order to save energy as much as possible in terms of energy consumption, the demonstration project with the latest technologies is composed of 100 households, apartments and multi-family houses   High-quality insulation was installed on the outer walls of all houses, and a solar panel for solar power was installed on top of it. All windows were constructed with triple-confidential windows, and geothermal circulation pumping was installed for cold and hot water    In the winter when demand for heating is high, or in summer where demand for cooling is high, electricity will be supplied through the power grid. However, during the rest of the year, electricity generated from the solar panels will be supplied to the grid if you look at it for a year, it's called net zero house because its energy consumption is zero   The central government and the government of the city of Seoul pla

The world's largest industrial ESS device is installed in Korea

Image
Currently the world's largest ESS facility is a 100MW capacity facility installed by Tesla in Australia. the operation started on December 1 and was installed in the north of Adelaide, South Australia this ESS unit, which is connected with the wind power plant for backup system to improve the stability of electric power grid this ESS device is also famous for the so-called 100-day promise of Tesla CEO Elon Musk unfortunately the honor of the world's No. 1 ESS facility is likely to be lost if it goes months late r Because Hyundai heavy industry subsidiary Hyundai Electron is installing 150MW industrial ESS equipment in Ulsan, South Korea this ESS device, which is expected to enter the market by early next year, is simply a facility to reduce electricity costs without regard to solar or wind power generation In Korea, the electricity charge from midnight to the next morning is quite low compared to the time of day. therefore, it is the idea to store the electr

Korea Ministry of Trade, Industry and Energy plans to implement the project "re 3020" re 3020 project is scheduled to start in earnest in 2018 with the plan to expand the current 7% of new and renewable energy to 20% by 2030 this plan to install new facility of 36.8GW of solar power & 16.7GW of wind power and aim to achieve 36.5GW and 17.7GW respectively until 2030 The major players in this project are major power producers and public corporations including KEPCO, and they plan to lead them to 24.1GW, which is close to 50%  The remaining 50% will be led by private operators. For this, the central government is considering regulatory reforms such as introduction of the FiT system If the FiT incentive system for renewable energy is introduced again, it will be resurrected within eight years after the former President Lee Myung Bak abolished the FiT system Opposition parties, mainly opposition parties, say that the policy is too dominated by renew

2016 Korea solar industry insight report

Image
According to KNREC statistics, we have released finalized statistics on renewable energy in 2016  2016, the total Korea domestic power generation capacity is 561,825GW and the PV power generation capacity is 5,122GW.It was 0.91% less than 1%Even if we add wind power capacity (1,683GW), the total is 6,805GW, 1.2%, which is just over 1% . As a matter of fact, except for hydroelectricity, it is not enough to say that any part is meaningful. The inclusion of hydroelectric power will give a plausible figure of 7.24% of total power output In 2016, about 909Mw of PV solar power generation facilities have increased, and the total installed capacity of solar photovoltaics in Korea has been 4.502Mwh
