Energy technology: Cheaper and better solar-powered electric lights promise to do away

WHICH plastic gadget, fitting neatly in one hand, can most quickly improve the lives of the world's poorest people? For the past decade the answer has been clear: the mobile phone. But over the next decade it will be the solar-powered lamp, made up of a few light-emitting diodes (LEDs), a solar panel and a small rechargeable battery, encased in a durable plastic shell. Just as the spread of mobile phones in poor countries has transformed lives and boosted economic activity, solar lighting is poised to improve incomes, educational attainment and health across the developing world.
As previously happened with mobile phones, solar lighting is falling in price, improving in quality and benefiting from new business models that make it more accessible and affordable to those at the bottom of the pyramid. And its spread is sustainable because it is being driven by market forces, not charity.Phones spread quickly because they provided a substitute for travel and poor infrastructure, helped traders find better prices and boosted entrepreneurship. For a fisherman or a farmer, buying a mobile phone made sense because it paid for itself within a few months.In the spring and fall, make sure that solar panels are clear of falling leaves or other blowing debris. China Portable Wholesalers should also take care when raking or leaf blowers do not damage any solar lights or solar panels. Many people take solar accent lights in during fall clean-up and place them back outside during the spring, especially if they hire other people to do yard work. The economic case for solar lighting is even clearer: buying a lamp that charges in the sun during the day, and then produces light at night, can eliminate spending on the kerosene that fuels conventional lamps. Of the 1.4 billion people without access to grid electricity, most live in equatorial latitudes where the sun sets quickly and there is only a brief period of twilight. But solar lamps work anywhere the sun shines, even in places that are off the grid, or where grid power is expensive or unreliable.
The potential savings are huge. According to a recent study by the International Finance Corporation, an arm of the World Bank, $10 billion a year is spent on kerosene in sub-Saharan Africa alone to illuminate homes, workplaces and community areas. Globally, the figure has been put at $36 billion. Flexiway, an Australian-Argentine maker of solar lamps,Designed for China Solar laptop charger Offers on the move, the Generator provides up to 45 minutes of laptop runtime for every hour in the sun. It will power most modern laptops, tablets, professional digital cameras, and smart-phones. Even when solar charging is not an option, the internal battery holds enough power to more than double the runtime on many laptops and can also be re-charged from the included wall charger. found in its trials in Tanzania that households often spent more than 10% of their income on kerosene, and other studies have put the figure as high as 25%. And kerosene does not merely eat up household income that could be spent on other things. It is also dangerous. Kerosene lanterns, a century-old technology, are fire hazards.The company has plunged into this business with an aim to bring awareness among the people for energy conservation. Lighting Africa Offers are well recognized for famous eco-friendly solar lights products comprising solar lantern, solar water submersible pump, solar led light, solar water pump etc.This is the reason that solar power is getting special attention in all over the globe such as Indian. The wicks smoke, the glass cracks, and the light may be too weak to read by. The World Health Organisation says the fine particles in kerosene fumes cause chronic pulmonary disease. Burning kerosene also produces climate-changing carbon-dioxide emissions.
