Interesting Breakthroughs

  • One in five Australian homes uses solar energy. Amazingly, 19 percent of all Australian households have solar panels or solar water heaters installed.
    Of the 19 per cent, 14 per cent of these households have rooftop PV.
    A report found an inverse relationship between average incomes and solar penetration levels; that is, as income levels increased, solar uptake declined.

  • One of the more promising solar technologies that researchers have been working on for years is spray-on solar cells.
    The idea is that being able to apply solar cells to surfaces like House and car roofs, airplane wings, basically anything that is exposed to sunlight and turn them into a solar panel.
    The researchers say that a surface the size of a car’s roof wrapped with CQD-coated film would produce enough energy to power three 100-Watt light bulbs—or 24 compact fluorescents.

  • Solar PV customers understand that they can generate cheap electricity with rooftop solar. That electricity is good for lighting, appliances, air conditioning and other household uses only. But homeowners often ask about heating their homes with solar. There is an option: heat pumps combined with rooftop PV.
    There are new generation pumps called “mini-split systems” that allow you to heat and cool a few rooms at a time, instead of your entire house.

  • L&T Construction, India’s largest solar EPC Company, has recently commissioned the world’s largest Solar Photovoltaic Plant of 7.52 MWp capacities on a single roof at Amritsar in Punjab in September 2014.
    For this project, L&T employed multi-crystalline module technology and central inverters to optimize efficiency. More than 30,000 panels were erected on the rooftop of the shed spread over 94,000 sq.m area.

  • Tamil Nadu, a state that has faced power supply and demand issues for some time, is the latest province to join the solar frenzy in India. The Tamil Nadu Energy Development Agency (TEDA) has announced plans to set up rooftop solar arrays at about 300 government buildings across the region.
    The agency is planning to cover 50 village government buildings and 234 local government buildings in the area with rooftop solar with a capacity of 7 kW each.

  • Americans installed a record number of rooftop solar panels in 2013 with a total capacity of 4GW, A drop in solar panel prices combined with the rise of leasing programs has made it less costly and easier for homeowners to invest in rooftop solar panels.

 

  • Team DTU from Denmark has incorporated brand new innovations into their extra slender FOLD house at the Solar Decathlon Europe.
    Three main elements are crucial to the elegance of this prefabricated home: a super thin rooftop photovoltaic system, strong Finnish kerto wood and high-insulating Rockwool Aerowolle.

 

  • Oahu’s rooftop solar photovoltaic energy industry saw its 19th straight month of year-over-year decline in November.
    Through the first 11 months of this year, 5,914 permits were issued on Oahu, down 51 percent from the same time period last year, which saw 12,163 permits issued.

 

  • Marks & Spencer recently announced that it will be installing the UK’s largest solar roof by mid 2015 at its distribution centre at Castle Donnington. The roof array will be linked to one of Europe’s largest solar thermal walls.

 

  • Brazil’s stadium Estádio Governador Magalhães Pinto has rooftop solar panels. The 1.4 MW solar array lines the stadium’s circular rooftop.
    The stadium joins Mané Garrincha stadium, which will have a 2.5 MWp solar array that will provide enough solar energy to power nearly half of the stadium.

 

  • MGM Resorts announced that it has installed the largest rooftop solar array in the US – the second biggest in the entire world – on top of the Mandalay Bay Resort and Casino.
    Also keep in mind that the stunningly massive array will only generate a mere 1/5 of the building’s needs.

 

  • Danish practice GPP Arkitekter unveiled their groundbreaking Plus Energy Headquarters for Syd Energy (ES) Company in southwest Denmark. The round building is one of Europe’s five largest office buildings designed according to passive house sustainability principles
