  • eBay is awash with these solar mobile power banks, most claiming way more storage capacity than is genuinely inside – this one has just 4,800mAh of LiPos. The unit only charges properly in full sun – in low light it wastes all the energy it receives by burning it up in 4 blue LEDs that seem to stay on continuously. The physical construction is dreadful – everything inside is held together with sticky tape and foam pads. Even the circuitry on the PCB is nothing special. It’s a waste of money – don’t buy it.



    The facility in Kamuthi, Tamil Nadu, INDIA has a capacity of 648 MW and covers an area of 10 sq km. This makes it the largest solar power plant at a single location, taking the title from the Topaz Solar Farm in California, which has a capacity of 550 MW.
    As of 30 September 2016, the country’s solar grid had a cumulative capacity of 8.63 gigawatts (GW).
    In January 2015, the Indian government expanded its solar plans, targeting US$100 billion of investment and 100 GW of solar capacity, including 40 GW’s directly from rooftop solar, by 2022.
    India is ranked number one in solar electricity production per watt installed, with an insolation of 1700 to 1900 kilowatt hours per kilowatt peak
