From 2014 to 2018 the global solar energy market, or 10 times times

Polaris solar PV net news: according to the latest IHSTechnology report predicts global grid-connected residential photovoltaic energy storage total market size will be 10 times-fold increase from 90 megawatts in 2014 to 2018, more than 900 megawatts.

Report, PV and battery manufacturer facing business opportunities continue to grow, mainly originated from the photovoltaic sector consumption continues to appeal, the Government launched the subsidy mechanism and residential users independent of the grid in real time will increase.

Obstacles to energy market “take off” barriers

In recent years, energy storage systems used in small photovoltaic systems are hosted numerous expectations. However, most of the deployed storage system failed to live up to those expectations. It was reported that the obstacles to energy market “take off” on the road, there are many barriers, which the whole State of the photovoltaic market is one of the most significant barriers.

“Last year, many storage systems for large-scale residential solar markets have weakened significantly, due to cuts in government subsidies to a large extent. “IHS Energy Department research director Sam ˙ Wilkinson (SamWilkinson) said,” we expect, Italy, and Germany and the United Kingdom three market 2014-2017 housing during installation from April 2013 to cut by nearly half. ”

Battery and power conversion equipment prices were still high

Report finds need to be integrated to the battery and power conversion equipment of PV system prices has been at high levels, this is one of the main factors that inhibit market.


Although expects lithium-ion (Li-ion) battery’s average price (account for most residential photovoltaic energy storage facilities) of this year reached 20%, but still high price has been seen as the main obstacle. It can be seen that solar energy profitable business model is complex, only exists in small “niche” – Government subsidies can contribute to market growth and take a keen interest of the end user.

“Frankly, it will add residential PV installations of energy storage systems for fiscal reasons is not, but the business case is still highly dependent on the number of variable factors, such as self-consuming goal can be realized, as well as the future development of retail electricity price level for 20 years. “Wilkinson added,” in fact, these variables cannot be sure so ROI is harder to predict, naturally suppresses the end user wishes of investing in residential solar energy storage system. ”

2015 is expected to break down market barriers

However, 2015 energy storage market is expected to make significant progress, many barriers to eradication. IHS predicted that within three years, lithium ions decreases in average price will be 15%. In addition, the residential PV market will return to growth for the first time. These factors are expected to jointly promote the surge in residential solar energy storage market in 2015, 90%.

PV consumable sector boosts long-term growth

Despite Government subsidies and growing desire for independence from the grid of residential users contribute to the residential development of photovoltaic energy storage market, but IHS think the main motivation is that residential PV system production of consumable electric power increasingly attractive.

In many cases, compared with the costs of PV power, retail electricity prices remain relatively high. Compared to selling to the grid using PV system produces electricity more economically attractive, and solving the electricity bill.

As energy costs continue to decline, install a battery to store surplus electricity has become a viable option, there’s no need to enter the grid. Although Germany battery cost remained up-no storage system for photovoltaic facilities investment return of more than fitted with photovoltaic installations for the storage system, but IHS predicted such a situation reversal by 2016.

Attractive consumable photovoltaic market include Italy, and Germany and the United Kingdom, and Australia. Projected 2018 photovoltaic energy storage market in these countries accounted for just 20% per cent of the global total PV installed capacity, but with a global PV installed capacity exceeds the proportion of energy storage 40%.

Promotes the development of residential energy market dynamics

Despite the consumption sector is driven by residential photovoltaic energy storage market is the most important driving force, but other factors have also played a positive role.

IHS predicted that despite the generous solar subsidies less attractive rates for consumable type Department in 2018, Japan is expected to as much as 200 MW of residential photovoltaic energy scale ranks first in the world. In order to ease electricity shortages in the country, and Japan has launched the subsidy mechanism of lithium-ion batteries used in residential and commercial buildings. Due to frequent power disruption and peak and off-peak electricity price have significant differences, people with energy storage system for photovoltaic facilities interest is getting stronger. Although with energy storage system for photovoltaic facilities capable of providing backup power, but this factor in promoting the development of global markets on the road to play only a small role.

However, the report pointed out that standby power is promoting an energy storage system for PV system users in North America, the only driving force, expected in 2018 will be one of the largest residential solar markets in North America. (Translator: Bian Xiaoyun)
