Sharma also said: "Although China will become the world's largest market for PV demand, it will also face the biggest risk of supply and demand balance in the photovoltaic industry. If China can complete more than 17 GW of PV installed capacity in 2015, it will create a photovoltaic company for China. A healthier operating environment returns to a more reasonable profit margin."
PV inverters resume growth
IHS also predicts that the PV inverter market will resume growth. According to Cormac Gilligan, senior analyst of IHS PV inverters and system balances, sales of PV inverters will increase from $6.6 billion in 2014 to $7.5 billion in 2018, a growth rate of more than 10%. With the growing demand for photovoltaics in China, Japan and other emerging markets, it is expected that global PV inverter production (calculated by AC grid connection) will increase to around 70 GW in 2018. However, price pressures will still exist. According to forecasts, the average global inverter price will decrease by 9% per year, in 2013 it will be 0.17 US dollars / watt, and by 2018 will be reduced to 0.11 US dollars / watt.
By 2018, three-phase low-power inverters below 36 kW will contribute 34% of the global inverter market. “Low-power inverters are becoming more popular in the global business and utility sectors, especially in China, the US and other core markets,†Gilligan said.
Increased demand for energy storage
The number of new PV systems with energy storage systems has grown rapidly. Against the backdrop of stable national policies and declining battery prices, IHS is optimistic that the capacity of newly installed energy storage systems will reach 3.6 GW in 2018, 15 times that of the 2014 231 MW energy storage system. Isabella Ni, senior analyst for energy storage and photovoltaic demand, said: "The growing demand for electricity and renewable energy will drive demand for energy storage."
At present, the biggest obstacle to the large-scale development of energy storage systems is the high battery prices; however, the cost of future energy storage systems is expected to drop significantly, and the price of lithium-ion batteries is expected to fall by 40% in the next three years. Ni said: "At present, lithium-ion battery technology is the current mainstream technology, which will account for most of the market share of the grid-connected photovoltaic energy storage market."
The price of crystalline silicon photovoltaic modules fell slowly in 2015
In 2015, the global production capacity of crystalline silicon photovoltaic modules will be greatly improved, and is expected to reach 76.6 GW. At the same time, capacity utilization will also increase due to increased downstream demand. IHS predicts that the operating rate of crystalline silicon PV modules will increase to 72% in 2015.
IHS forecasts that the global average price of crystalline silicon PV modules will decline slightly by 5% in 2015 compared to 13% and 11%, respectively, in 2013 and 2014. Jessica Jin, senior analyst of the PV supply chain, said: "The rising demand for downstream installations and the increase in the operating rate of manufacturers will prevent the continued decline in the price of PV modules in 2015."
High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
