'Two-thirds of German PV installers now offering storage'

Over two-thirds of German PV installers are now offering their customers energy storage options, while their British and Italian counterparts are beginning to follow suit, according to a new report from EuPD Research.

Two-thirds of German PV installers are now offering storage options, according to EuPD.

In ‘European PV storage market insights 2014’, the market research firm analysed the market development of storage and surveyed the attitudes of installers towards storage in the key European territories of Germany, the United Kingdom, Italy, the Benelux countries and France.

Countries surveyed were selected as target markets which have what EuPD calls “an attractive small system market” and where storage is already being offered to customers, to a greater or lesser extent.

While technological progress in storage is uncertain, EuPD found that in some of the key markets following Germany's lead, as many as a third of surveyed companies intend to begin offering storage to customers this year. Germany, which offers a percentage of storage system cost as a direct subsidy to consumers, leads with the aforementioned two-thirds of installers offering storage. A third of Italian installers and a third of British installers surveyed said that they would begin offering storage this year.

On the other hand, EuPD reported that French installers surveyed did not intend to offer any more storage systems this year than in previous years, with French electricity prices remaining relatively low.

Meanwhile EuPD researcher Angelika Leiss said that the Benelux countries cannot yet be said to have an existing market, but explained that the potential for growth was good in those countries due to the region’s PV market being dominated by private rooftop systems and high electricity prices, “a good prerequisite for the combination of photovoltaic and energy storage systems”, according to Leiss and EuPD.

The EuPD report takes as a starting point the assumption that storage combined with energy management will assist EU countries in reaching targets for renewable energy, by allowing fluctuating wind and solar resources to be used to their full potential at both consumer and grid level. EuPD also sees storage as likely to become increasingly important to the PV industry in terms of added value that installers can provide, as government funding for solar systems decreases or ceases altogether in many regions.

On this basis, the firm examined whether storage systems are being offered and to which customer groups, what kind of storage systems installers might offer, what kind of brands and brands awareness exist in storage and asked how satisfied customers are with the options offered, if any. The report then also examines when economic feasibility of storage will be reached in the target markets identified by EuPD.

At the Ecobuild sustainable building show in London last week, PV Tech spoke to PV companies including Renesola, Sharp Solar and inverter maker Power One, all of which either had already launched storage systems for residential customers or had products being prepared for launch to key markets, in most cases beginning with Germany. With specific regards to the British market, the EuPD report finds that the high price of storage systems is still an obstacle for many installers and their customers.

Andrew Lee, general manager at Sharp Energy Solution Europe’s solar commercial sales division, told PV Tech that having already launched a storage product in Germany, the company was now "soft launching" it in the UK and “gauging what the markets requirements are with the hope of actually doing a firm launch early on in the summer”.

Lee said that in addition to targeting markets such as Germany which offered subsidies for storage, there was a strong argument for offering storage to other markets.

“It obviously does help in countries where they do offer an incentive, but storage itself makes economic sense if you look at the figures, depending on your system size and your own usage in other countries where there aren’t incentives,” said Lee, citing the possibility of enabling self-consumption as a potential strong driver for the storage market.
