Costs were dropping rapidly, with the price per watt of solar modules falling from around $100 in 1975 to under $10 a decade later. While still a tiny fraction of overall energy generation, solar was becoming an increasingly viable technology. The stage was set for a solar energy revolution.
26 Απρ 2023 · With the way the cost of solar has plummeted in the past decade, it's easy to forget that going solar had a completely different meaning even just 15 years ago. Let's go back a few centuries to the origins of solar PV and explore the history of solar energy and silicon solar technology.

From 2011 to 2012 alone, the average price of residential solar fell from $6.62 per watt to $4.67 per watt. By 2015, the price decreased even further to $3.36 per watt, leading to more residential solar power being installed in the U.S. in 18 months than ever before.
Key takeaways: Ancient civilizations harnessed solar power with mirrors and architecture. First functional solar cell created in 1883, improving efficiency to 1%. 1950s saw practical silicon photovoltaic cells and solar power in space. Solar technology advances in the 1980s, lowering costs and increasing efficiency.
8 Ιουλ 2022 · Over the decades, continuous improvements were made to solar power technology, reducing costs and improving efficiency, leading to the commercialisation of solar panels. In 2016, researchers at The University of South Wales reached 34.5% efficiency.
