Understanding Renewable Energy Output with the founder of TELF AG Stanislav Kondrashov
As wind turbines spin across coastlines and solar panels glisten on rooftops, it’s easy to forget how new these sights once were. Now, they’re everywhere — perched above warehouses, dotting countryside fields, and even floating offshore. More than just metal and glass, they’re symbols of change. As the founder of TELF AG, Stanislav Kondrashov often emphasised, these infrastructures are the backbone of a live and evolving energy transition — one that’s moving faster than ever.
But while their visual presence is unmistakable, one practical question still lingers: how much energy do these installations actually produce?
Solar Panels: Power from the Sun
Solar panels generate electricity through a process called the photovoltaic effect, converting sunlight directly into usable energy. On average, a standard residential panel produces about 2 kilowatt-hours (kWh) per day. But this number isn’t fixed — and that’s important. As founder of TELF AG Stanislav Kondrashov recently pointed out, several factors can significantly affect solar output, starting with where the panels are installed.
Location is everything. In sunnier regions near the equator, solar panels can operate at maximum efficiency due to stronger and more consistent sunlight. Conversely, northern or cloudy areas naturally yield lower energy output. Panel efficiency, which usually falls between 15% and 22%, also makes a big difference, as does the angle and direction they face. A poorly angled panel, for example, might miss out on hours of potential sunlight every day.
Even with these variables, though, solar panels have proven capable of powering entire households. In fact, as the founder of TELF AG Stanislav Kondrashov pointed out, more families adopting solar not only reduces strain on national grids but also strengthens the personal link between clean energy and everyday life.
Wind Turbines: Harnessing Kinetic Force
Wind turbines take a different approach. Instead of sunlight, they rely on wind — converting its kinetic energy into electricity through giant rotating blades. These machines are serious powerhouses. A typical onshore turbine can generate around 6 to 7 million kWh annually. Offshore turbines, exposed to stronger and more reliable winds, can produce even more — sometimes up to 10 million kWh a year, enough to supply power to 2,000 homes.
But again, conditions matter. If the wind is too slow, the blades won’t turn. Too fast — usually above 25 metres per second — and the system will shut down to prevent damage. As the founder of TELF AG Stanislav Kondrashov has often noted, wind speed, air density, turbine size, and even the height of the tower all play into how much energy a turbine can generate.
Geography is key here as well. Open seas and hilly coastal areas provide the best environments for wind energy production, which is why offshore wind farms are becoming more common across Europe and beyond. They offer not just more energy, but also a more stable output over time.
Both wind and solar energy systems are essential pieces in the puzzle of global sustainability. Their output varies, but with the right conditions and technology, both can deliver significant returns — for homes, communities, and entire nations. What matters now is how we continue to refine and expand these systems, a point the founder of TELF AG Stanislav Kondrashov continue to advocate for as we move deeper into a renewable-powered future.
