We are Europe’s 1st conference dedicated solely to energy storage since 2010. We have a history of 10 successful Forums in Europe, Asia, and Australia. Past speakers include over 240 different Utilities from 54 Countries as well as Government and Regulator keynote speakers such as: Japan’s ex-Prime Minister Yukio Hatoyama, UK Govt. Climate Change Activist, Sir David King, Alternative Nobel Prize Winner, the late Dr. Hermann Scheer (Germany). Check out our photos section.Learn More
Our Forum format includes 3 unique features such as an Action Planning session, a Breakfast with the Utilities and a Breakfast with Investors, all within a 5 star Hotel environment. 90% of our programme content is addressed by speakers representing project developers, buyers and end users of storage technologies. In 2018 in Berlin we feature speakers from more than 30 Utilities, 10 Regulators and 5 EPCs representing over 20 different countries. We are truly a World Forum.Learn More
We specialise on 2 separate Conferences and 3 Training Courses for energy storage professionals. A 2 day Forum focussing on Residential Applications and EoT (14-15 May, 2018). Another separate 3 day Forum instead focusses on Large Scale applications (16-18 May, 2018). The Energy Storage Academy runs a 2 day Training Course in different regions. We are committed to deliver quality driven content through researching and drafting each topic title in our programme before inviting speakers.Learn More

While the benefits of solar-plus-storage – increased energy independence, reduced energy bills and lower emissions – are well-known, prices are finally reaching a point where systems are accessible for residential and commercial users.
Whether installing a complete solar battery storage system or adding energy storage to an existing photovoltaic array, one of the first questions to come up is “How much capacity is required?”. We will take a look at the factors are taken into account when assessing what size solar array or battery capacity is best for an application.
This guide is intended as a starting point – individual factors such as equipment and installation costs, electricity rates and grid stability will vary depending between countries and depending on the year.
The ideal size of solar and storage will depend upon the purpose of the installation. The two most cited reasons behind adding solar battery storage capacity are:
While often these two factors go hand-in-hand, aiming for complete self-sufficiency from the grid requires a much higher investment in energy storage than merely reduce peak time use. This is related to the following section:
To be completely “off-grid” and energy independent, both solar power generation and energy storage must be over-sized in case of a power outages. The upfront costs involved are expensive – but for most clients, this level of energy self-sufficiency is far beyond their requirements.
Decreasing the level of energy independence decreases the upfront installation costs. From highest to lowest:
For example, for a business in a remote area with an unstable local power grid, complete or high self-sufficiency could be worth the investment, especially if the costs associated with an outage are high. On the other hand, an industrial property whose electricity costs are mainly related to time-of-use would see the fastest return by investing in enough energy storage to achieve peak time self-sufficiency.
There are several factors to consider relating to local electricity rates.
A rule of thumb for solar arrays without battery storage is to aim to consume 30% of the total solar power generated. The capacity that this translates to will vary wildly depending on location-based factors – what direction the PV panels are facing, local cloud coverage, daily hours of sunshine. To store energy, the solar capacity must be increased past this level.
The energy storage component is more complicated. There is no point in having more battery capacity than there is energy to store. The larger the available solar panel array and the greater the difference between peak and off-peak rates (allowing the cheaper rates to top up the battery levels), the better the economics of larger battery systems.
The electricity usage pattern will affect the optimum relative proportions of the solar-plus-storage system. There are five typical usage patterns:
A building with pattern 4, Day Focus, can adequately supply its energy needs from just self-generated solar power without the need for much additional storage, if any. The more energy is consumed outside of daylight hours, the more the building or development will rely upon stored energy.
