AlsoEnergy has developed several new reporting and collaboration enhancements to its cloud-based ‘PowerTrack’ Energy Management Services software. The newest features allow developers and investors in solar energy systems to create performance models and compare operation between sites and models to quickly detect underperforming components and generate better system returns.
DuPont Microcircuit Materials (MCM) has introduced ‘DuPont Solamet PV416’ photovoltaic metallization paste used to raise the efficiency of thin film photovoltaic cells. The front-side silver paste material has the capability to be processed at temperatures below 140°C, and is designed to provide improved contact resistance, conductivity, adhesion and fine line resolution when printed on Transparent Conductive Oxides (TCOs). The new paste has been claimed to have boosted CIGS thin-film manufacturer, Midsummer AB’s cell efficiencies by as much as 0.5%.
centrotherm photovoltaics is offering an upgrade package for its centaurus technology, which combines a selective emitter with a dielectric passivated backside. The technology implementation is said to already be combined with fine line printing, reducing paste consumption of the front side silver paste by more than 20%. The achieved conversion efficiencies on 156x156mm² monocrystalline (cz) wafers have already reached the 20% level. Currently, centrotherm said it has more than 50MW of centaurus technology being ramped into volume production.
Venture capital investors love to use baseball as a metaphor for their wins and losses. The technique to score a home run puts the hitter at risk of being caught out or missing the ball: swinging for the fences is an all-or-nothing strategy.
In 1854, Matthew C. Perry - the Commander of the US Navy - compelled Japan to openup to its economy to foreign trade, after more than 200 years of a self-imposed isolation policy enforced by the ruling Tokugawa Shogun. The Commander arrived in Japan with four black-coloured US Navy warships, billowing black smoke. Later the term ‘Black Ships’ would be coined in Japan to symbolize any threat imposed by Western technology.
Net metering is becoming an increasingly divisive issue in the US, with a dividing line as distinct as night and day. Solar companies and their customers count their sunshine dollars earned or saved – utilities count their revenue losses.
The PV industry has historically trusted global PV installation figures released by PV inverter market leader, SMA Solar Technologies due to the fact it had a direct route to a major part of the sector. This was often supported by market research figures or at least an alternative measure to compare different figures produced due to the difficult task in accurately reporting annual global installation levels. Not surprisingly, when SMA claimed its own market share figure for inverter sales the figure was rarely questioned.
Enlightening opinions from US energy commissioners on what they really think about renewables and the electricity industry's incumbents can only be said out loud once they've left their post: a reversal of poacher turned gamekeeper.
As California's "dumb" grid gets smart over the next decade, a clever convergence between technology and PV systems is also required. Otherwise, attempts to harmonize the state's 33% Renewable Portfolio Standard are at risk of turning into a cacophony for policymakers, utilities and technologists.
Despite the phenomenal success of California's Renewable Portfolio Standard in creating a market for utility-scale solar, many in the industry are forecasting the end of the transmission line for large central stations stranded out in the desert.
