How do you charge your phone when the sun doesn’t shine?
Seeing our mobile phone running low on juice can induce near panic in many of us these days – we’ve become so reliant on them.
So imagine what it’s like living in a remote village whose only electricity comes from solar power. What do you do when the sun doesn’t shine?
Not only might your phone die, you might not have enough stored electricity to keep the lights on for more than a few hours. You have to light candles or a smelly kerosene lamp to see what you’re doing at night.
But one solar power firm, Azuri, reckons it has an answer to this problem.
Its HomeStart system learns your electricity usage patterns and monitors climatic conditions to make sure the stored solar power is used in the most efficient way.
