The global solar market grew by 29.3% in 2018 2. Growth rate slowed in the previous year compared to 2016 3. China remains the world leader in solar power with 52.8GW 4. US ranks second in new solar power installation with 10.6 GW followed by India at 9.6 GW. Janaki Rajagopal_ 18068 GROWTH OF SOLAR ENERGY CAPACITY WORLDWIDE Janaki Rajagopal_ 18068 RECENT DEVELOPMENTS IN SOLAR ENERGY LATEST EMERGING PANEL OF TECHNOLOGIES INCLUDE: 1. Solar skin design: Makes it possible for solar panels to match the appearance of a roof. 2. Solar powered roads It has ability to generate clean energy and includes LED as well as thermal heating capacity 3. Solar Water Purifiers This solar devise can purify water when exposed to sunlight. 4. Solar thermal fuel It is a chemical that can absorb solar radiation, store and release it again as heat. 5. Wearable solar Tiny solar panels can now be stitched into fabrics of clothing used to power portable devices. Janaki Rajagopal_ 18068 What is the FUTURE of solar energy in the next 5–10 years? Will solar energy’s costs decrease? If so, by how much? Will its efficiency increase? If so, by how much? • Climate change is a real and present threat to the future of human life and all other life on Earth. • Solar is by far the largest energy resource available on Earth— renewable or otherwise • Solar photovoltaics is growing fast— faster than any other energy technology. Cumulative installed PV capacity worldwide has doubled. So now we know a few things: Climate change is happening, we need lots of low-carbon energy to stop it, solar is one of our only practical options, and solar PV is growing faster than anyone ever imagined. • Solar photovoltaics are by far the leading solar technology in terms of total deployment, it operates silently and at low temperatures, and it doesn't require much maintenance over its 25+ year lifetime. • Aside from solar heaters, which are used widely in China for heating domestic water and in the U.S. for keeping swimming pools warm. Solar heating can’t be compared directly with PV since its output is heat rather than electricity • Today's commercial thin-film (TF) PV technologies, they use much less material and can be made at relatively low cost with high efficiency • The future of solar energy is very bright until unless we will find some other means of generating energy which is cheaper than solar. • Free:- Yes, solar energy is free. The sun will rise everyday and you can utilize solar energy • No pollution:- If we ignore the pollution of manufacturing the solar panel, there is no pollution while generation. • Less Maintenance: There are a lot solar technology which require very minimum maintenance. CHALLENGES • High initial installation cost • Efficiency • Short battery lifetime Wilson Pinto-18186 • Shortage of skilled power • Lack of technical knowhow on behalf of user • Unsustainable weather condition Wilson Pinto-18186 • Solar intensity • Reliability • Effect on environment Wilson Pinto-18186 conclusion • solar electric generation has the highest power density among renewable energies, and with thermal storage can generate electricity in a predictable manner even when the sun is not shining. • Solar energy is a clean, pollution free and renewable source of energy.
