This is for my wish list but you can pre-order them now at https://solargaps.com/. SolarGaps smart blinds automatically track the sun throughout the day, adjusting position to the optimal angles to generate solar electricity to power devices in your home, apartment or office.
At about $1,000 a m², they’re not cheap… but discount the cost of curtains, the ability to control your blinds with your mobile phone, and maybe you can justify them. But you can be sure, if this catches on, prices will drop!
They generate up to 100W-150W of renewable energy per ±1m² of window, enough to power 30 LED light bulbs or three MacBooks. So with ±4m² of window on the north-eastern face of the house, I would be able to generate 1.6-2.4kWh over four hours just on one side of the house.
