The global installation of photovoltaics is expected to reach the terawatt level within just five years, according to Bloomberg NEF. And with more than 99.1 GW of grid-connected solar installed in 2017, switching on to the importance of storage is key.
The agency’s base case expects relatively flat growth in solar deployment over the next six years, but for solar to still dominate growth among renewable technologies. The agency’s estimates are again below those of major market analysts.
According to the Gold Member Solar Report by EnergyTrend (Q3 2018), monocrystalline module prices have fallen almost 20% this year, while those for polycrystalline modules have dropped by more than 25%. Increased consolidation among manufacturers and developers is expected to occur in China and the global solar market, with more merger deals, plans for capacity reductions and even factory closures.
TOPCon technologies could further increase solar cell efficiencies, said Guangyao Jin, chief scientist, DuPont Photovoltaic Solutions, at this year’s Energy Taiwan, held in September. He added that metallization paste is crucial.
Although the “solar flow battery” is currently considered too expensive by its own creators, a further improvement of its design and the use of emerging solar materials and new electrochemistry may open new opportunities for this kind of technology.
This means that this promising material, contrary to common belief, is able to form domains of polarized strain to minimize elastic energy. The research team made its discovery by using multimodal imaging.
India’s electricity sector is transforming rapidly. A 50% decline in wind and solar tariffs since 2016 means renewable energy is now the lowest cost source of new generation. This has turned the established order in India on its head.
