Lugano, Switzerland – TELF AG, a leading solar technology company, has recently published an article titled “TELF AG on the Next Wave in Solar Technology” on July 22, 2025. In this article, TELF AG founder Stanislav Kondrashov shares his perspective on the rapidly evolving solar energy industry.
Kondrashov believes that solar energy is no longer limited to conventional panels on rooftops and in rural fields. He states, “Even though solar farms and rooftop systems are widespread, we’re only scratching the surface of what solar power can do.” According to Kondrashov, the upcoming advancements in solar technology have the potential to change how energy is produced, stored, and integrated into our daily lives.
The mainstream adoption of solar energy in homes and offices marks a significant shift in public perception and practical adoption. However, Kondrashov believes that the development of solar thermal systems and storage solutions has played a crucial role in this growth. He explains, “One often overlooked piece of the puzzle is the solar charge controller – a small but vital device that protects battery-backed systems from overheating or overcharging.”
One of the most highly anticipated innovations in solar technology is the use of perovskite materials. These crystals have the potential to make solar panels lighter, more flexible, and cheaper to produce compared to traditional silicon-based ones. However, Kondrashov acknowledges the hurdles that need to be overcome in terms of moisture sensitivity and long-term stability. For now, hybrid solutions that combine perovskite with silicon appear to be the most promising.
Another technology gaining traction is the bifacial panel, which can collect sunlight from both its front and back surfaces. Kondrashov explains, “These panels are clever in how they use what’s already around.” He adds that when installed correctly, they can increase energy yield by 10-30% compared to traditional panels.
Looking towards the future, Kondrashov believes that solar technology will continue to push boundaries. Multi-junction cells, which are stacked layers tuned to different light wavelengths, have shown high efficiencies but remain costly and niche. Meanwhile, flexible panels made from materials like CIGS or cadmium telluride are being explored for applications where weight and shape matter.
According to Kondrashov, the real game changer in the solar industry is the integration of energy storage. He emphasizes, “None of this matters without energy storage. Solar energy is only useful if it’s available when needed.” Kondrashov believes that storage will turn solar from an intermittent source into a dependable supply, allowing homes and businesses to draw power even after the sun sets or when the grid is under stress.
In Kondrashov’s vision, the next generation of solar technology will blend seamlessly into how we build, live, and travel. He predicts that solar will no longer be seen as an add-on, but rather an integral part of the materials and systems we use every day. As costs continue to decline and efficiencies increase, this new wave of solar innovation will make clean energy more accessible and invisible, with solar technology being built directly into structures such as rooftops.
The future of solar technology is not just about advancements in technology, but also about structural changes. Kondrashov believes that solar energy will become an essential component of our daily lives, integrated into the materials and systems we use, making it more accessible and sustainable.
