November 2012 FiT rates revealed

Ofgem has released its official installation figures for May, June and July which determine what the feed-in tariff rates will be starting from November 1 2012.

The Department of Energy and Climate Change (DECC) has identified three capacity bands in which installed capacity is monitored: Domestic Scale (0-10kW), Small Commercial (10-50kW) and Large Commercial installations (50kW-5MW). The installation levels in each of these bandings will determine how much the various FiT banding rates will be reduced by. Installations in the domestic-scale banding stood at 163.769MW. As this lies in between 100-200MW this will enact a 3.5 percent tariff digression on the existing ≤4kW tariff band (16p) and >4-10kW tariff band (14.5p).

PV System Values: Solar Energy Needs Electrical Storage Now

By Joseph McCabe, PE

Why Storage 

In 2002 the California Energy Commission Public Interest Energy Research (CEC PIER) funded an investigation into the value of electrical storage combined with PV by Dr. Richard Perez of the State University of New York Albany. This work was intended to address the intermittency associated with PV technology.  Intermittency is the reduction of solar output caused by the movement of clouds over PV modules. Dr. Perez came up with the term Solar Load Control (SLC).

REA STATEMENT – Current situation regarding FiT rates for solar PV

As you are aware, last week the Government lost its appeal against the Court ruling in December that its proposals to change the FiT tariff rates for solar PV were unlawful. However, the Government is now seeking leave to appeal to the higher level – the Supreme Court. They have 28 days from the judgment on 25 January 2012 to apply. It is not known whether the Government will be granted leave to appeal nor how long it will take for them to find out.

Record breaking: Solar Frontier pushes CIS thin-film efficiency to 19.7%

Solar Frontier has broken the record for CIS thin-film solar cell conversion efficiency using a sputtering and selenization process. The current CIS efficiency record at 20.3% was set with the co-evaporation processes.

The record conversion efficiency figure of 18.6%, verified by Japan’s Advanced Industrial Science and Technology (AIST), had stood for 10-years.  However in a joint collaboration with Japan’s New Energy and Industrial Technology Development Organization (NEDO), Solar Frontier has pushed the record to 19.7%, using solar cells measuring approx. 0.5 cm2, cut from a 30cm x 30cm substrate.

Regen welcomes announcement on Green Investment Bank

Renewables experts Regen SW have today welcomed Nick Clegg and Vince Cable’s announcement today that the Green Investment Bank will be an ambitious institution that will aim “catalyse an additional £15 billion of investment in the green infrastructure.”

Touching on many of the points that Regen raised in its recent Role of the Green Investment Bank paper, Nick Clegg stressed that the bank would be an independent organisation with a potential initial remit to focus on offshore wind, waste and non-domestic energy efficiency.

Merlin Hyman, chief executive of Regen SW, said: “This is good news for renewables companies and good news for the economy as a whole, as it will give businesses and investors the confidence they need to invest in renewables.”
