Battery energy storage systems: Positive developments regarding battery costs and improved regulatory frameworks will drive a remarkable growth

2015-10-08 |

The number of battery energy storage systems (BESS) used for stationary applications, both utility-scale and distributed, has started to grow significantly, cleantech advisory company Apricum (Berlin) reports. According to recent estimates, today’s annual market volume of about USD 1 billion is expected to reach an impressive USD 20 – 25 billion by 2024. Apricum identified three major drivers of growth for stationary BESS: 1st, positive developments regarding battery costs and 2nd, improved regulatory frameworks that both increase the competitiveness of batteries to participate in 3rd, a growing market for addressable services.

OELFLEX® SOLAR XLR WP – the waterproof solar cable certified by TUV


If photovoltaic cables are exposed to wet conditions over a long period of time, this may have grave consequences. This is because, with standard solar cables, moisture can permeate a cable that has been lying in water for a long time. The moisture then reduces the performance and insulation resistance of the cable. This can then result in short circuits, which may in turn cause power failures or, in the worst case scenario, even damage to the systems.

To overcome this problem, the Stuttgart-based Lapp Group presented a permanently waterproof solar cable at the Intersolar Europe 2015 exhibition. The cable in question is an electron beam cross-linked solar cable of type PV1-F in accordance with TUV 2PfG 1169/08.07 for durable and weather-resistant use in photovoltaic systems. Its optimised cable design and permanently high contact resistance mean that it will still function reliably even after years in damp environments or in water. Read more...

Solar Interview on desert challenges: O&M in China’s solar market

2014-12-16 |

There is growing discussion around the effects of harsh climatic conditions on the O&M of PV plants. It’s not just an issue for China, is it? No, definitely not. With cumulative global PV capacities reaching ~180 GW this year, the O&M market for solar PV installations worldwide is already substantial. Out of this total, more and more PV installations are operating under demanding climatic conditions, such as in deserts or in highly polluted areas, and this will increase in the future, especially in emerging markets. These challenging environments require module manufacturers and power generators to adapt their module design and O&M strategies accordingly, which is vital for plant profitability. Read more...
