The ranking of the best power storage from AlphaESS - by German CleanTech Institute with EuPD Resear

Recently, the German research institute EuPD Research released the list of the top ten energy storage brands in the European market in 2018. The ranking was jointly researched by the German Institute of Clean Technology and EuPD Research. With its superior quality and good reputation, the products of Alpha ESS stand out from the crowds of energy storage brands and is ranked among the top ten. The Storion ECO-ES5 is ranked first in the 5kWh.

EuPD Research is Europe's leading sustainability research company, specializing in B2B market research and providing comprehensive customized and quality research services to customers in Europe, Asia and America. EuPD's ongoing investigations continue to deepen its expertise in the field of renewable energy, especially in photovoltaic solar energy. With in-depth market knowledge and professional methods, EuPD has a excellent reputation in the industry and its reports and awards have become the "beacon" of the world's energy storage industry.

The expert of Energy Management at EuPD have analyzed 114 memory models from 75 companies in Europe and divided the models into four performance classes depending on their storage capacity. From the price, performance, installation and service aspects, four groups of rankings were drawn. Of which AlphaESS ranked in the top 10 in 3 groups. In the below 5kWh group. AlphaESS's economically integrated energy storage system, Storion ECO-ES5, topped the list.

The experts have to test on the depth of discharge of a model is, how many charging cycles it is designed for and what efficiencies it achieves. It has set these parameters in relation to the acquisition costs. In addition, they took into account the product characteristics of a storage system, whether it is expandable, can supply emergency power or what continuous output it achieves. In the installation / service category, EuPD has determined, among other things, how easy it is to assemble the storage units, what guarantees the providers grant and what kind of customer service they provide. It was also considered whether the manufacturers provided information on the origin of the related materials. 

A consumer from NRW of Germany points out that only the sun has the unpleasant property of being strongest when there is hardly anyone home. At noon, the residents of the home are usually at work, at schoo. And the e-mobile with them. Of course, the solar system owner can then feed the electricity into the grid. For this he receives around 12 cents per kWh as compensation. And in the evening, when he gets home, he has to buy the same electricity back for 29 cents.

Consequently, more and more homeowners install a photovoltaic system on the roof and a power storage in the basement. Store the surplus electricity during the low price period and use it again during the peak period, which reduces the waste of electricity and saves the electricity bills.

The combination of photovoltaic and energy storage has increased self-consumption rate and can bring more benefits. At the moment, the user's self-consumption rate is relatively low, probably less than 30%. The combination use of photovoltaic and energy storage has been able to Increase the rate of self-consumption to 80%.
