Foldable Solar Roof For Parking Lots

Today, solar energy is used all over the world. There are many improvements in already existing solar technologies. Entirely new technologies and innovative solar devices are emerging. More and more people have solar-powered homes. Back in 1956, the cost of solar used to cost around $300 per watt. Now, in the US, you can get rooftop solar for $1.49/watt from Tesla and a similar price from others.According to the latest news, a company in Switzerland and its partner, Kronberg and St. Gallish-Appenzellische Kraftwerke (SAK), have created something unique in the field of the solar technologies - a foldable solar roof, that comes out only when the sun is shining. It is not a typical roof designed for residential use. This roof is meant for parking lots and would keep vehicles cooled when the weather is hot. In this case, the energy from the sun is used for cooling, not for heating.

The companies started this project back in the spring of 2020 when they built the foldable photovoltaic system on the Kronbergbahn’s parking lot. When the sun rises, the solar roof unfolds and soaks up the rays to generate solar power, then when it’s cloudy, raining, or during night time, it folds up. 
The parking lot has 1,320 solar panels and produces 350,000 kWh per year. Right now, the companies are looking for investors who are interested in sponsoring a system. There are 660 panels available for the right of use - 330 panels are used directly by SAK and Kronbergbahn AG - and the license agreement is for 15 years.
Investors will receive five different experience vouchers during their 15-year right of use - the vouchers vary depending on the investment. If you are interested in investing in a panel, you have two options. You can invest in a whole panel or by the quarter:

1. Entire Panel CHF 800 ($852)
2. Quarter Panel CHF 200 ($213)
