In sunny regions, large-scale solar farms are already generating electricity a lot more cost-efficiently than coal-fired or nuclear power plants. Experts are forecasting that the cost of photovoltaics will continue to decrease, making them the most important energy source worldwide – a goal Bernhard Voll is passionately pursuing. He travels all over the world for SMA, making large-scale PV farms even more efficient and reliable.
PV power plant projects are long-time investments that operators, owners and investors must be able to rely on. Only if the calculated yields are achieved the investment is a success. Emphasis is not only on energy yield but also on availability. In our interview Boris Wolff, Executive Vice President Business Unit Utility at SMA, explains how availability rates, OPEX and 1500V technology contribute to successful utility-scale PV projects.
Decentralized, digital, networked – in the new energy world, various players constantly exchange information to ensure that clean electricity is always available to and affordable for everyone. But how secure is this system? Prof. Bernd Engel, an expert in sustainable energy systems at the Technical University of Braunschweig, and Marek Seeger, Information Security Manager at SMA, discuss the risks and opportunities of the digital energy revolution.
More is expected of them than of others: SMA solar inverters must work perfectly for many years. No matter in which country, in which climate, or to which power network they are connected.
Seals, rust protection, flawless insulation: Reinhard Lehmann, an analysis engineer, has been focusing his efforts for eight years now on helping SMA equip Sunny Central inverters for even more effective outdoor use. One of his responsibilities is ensuring that these high-performance central inverters are fit for outdoor use—at all times, anywhere in the world.
At the climate and stress laboratory the newly developed products are tested for reliability under extreme climatic conditions. SMA customers do not need to fear inverter damage due to freezing or overheating. We test the temperature limits for each new product.
