Solar lamps are becoming increasingly popular in the last few years, and for good reason. Solar-powered lighting systems are a greener, cleaner, and more sustainable alternative to traditional energy sources. Solar-powered lamps work by capturing sunlight and converting it into electricity, using photovoltaic cells. This electricity is then stored in a chargeable battery, ready to be used to power the lamps during dark hours. Solar lamps are much more efficient when positioned in direct sunlight, but they can still charge even in indirect sunlight. Solar lighting systems are much more economical than traditional sources, as there are no ongoing electricity or fuel costs. Solar lamps are also much safer, as they don't produce any heat or emissions, making them a safe option not just for the planet, but for people as well. Solar lighting systems can be used both indoors and outside, and they are an especially useful tool for people living in remote or rural areas that don't have access to conventional electricity. Solar lamps are also reliable and durable, meaning they can last up to 25 years. The Sustainable Development Goal 7 calls for universal access to clean and sustainable energy for all by . Solar lamps can help us achieve this goal by providing a clean and renewable alternative to traditional energy sources. Hopefully, solar lamps will continue to become more popular in the years to come.
