Boeing,the US Aircraft and Military Equipment Supplier had decided to sell its high efficiency solar cells in 2011.Note Boeing Subsidiary had created a record a couple of years ago with a 39.2% multi junction solar cell.These cells are primarily used in spacecraft where low space requirements require the use of high efficiency cells without major cost considerations.Spectrolab has continued to improve on the efficiency of the cells reaching 41.6% in a NREL Lab Test.Boeing has claimed a 60% marketshare of the space solar cell market and hopes to replicate that success on Earth as well.Boeing had earlier said that it would set up a 300 MW capacity by 2010 and market solar cells to CPV companies such as SolFocus.Will Boeing be Successful at Selling High Efficiency Spectrolab Germanium Solar Cells

The US Government has recently approved a number of Large Scale Solar Thermal and Photovoltaic Projects as Renewable Energy Projects rush to meet the December 2010 Deadline for getting the 30% Subsidy Cash Grants from the US Treasury.California has been leading the way with gigawatts of solar thermal plants being approved.However these projects are facing resistance from local groups due to different reasons.Green Activists are questioning the Environment Friendliness of these projects due to the harmful effects on endangered desert wildlife.While some projects have dedicated millions of dollars for the Rehabilitation and Resettlement of Tortoises and other wildlife,Green NGOs are not convinced.The 660 MW,$2 Billion Tessera Solar Thermal Plant has been put under a review of its approval due to protests that the approval was done with haste and without following proper procedures.Note Large Solar Thermal Projects need hundreds of acres of land and are being frequently built on public land.

First Solar,the US based Cadmium Tellurium (Cd-Te) is the lowest cost panel producer in the world today if you don’t include any penalty for low efficiency.Even if you penalize the Cd-Te Technology for its lower efficiency vis-a-vis the higher efficiency crystalline technology,First Solar is clearly the leader with a core cost of 74c/watt.The company has a roadmap of reducing the cost to 52c/watt by 2014 and given its track record it seems quite achievable.In Cd-Te,some new competitors have claimed even lower costs than First Solar but they have yet to prove it in large scale production.General Electric,Abound Solar are some of the other Cd-Te players which are planning commercial production in a year or two.But with around 2 GW of capacity,they will have a lot of catching up to do.

Australia has shortlisted 8 projects with 4 Solar PV and 4 Solar Thermal Projects for its Solar Flagship Program which will be decided in 2011.BP Solar with 150 MW and Suntech/Infigen with 195 MW are on the shortlist.The other 2 companies are energy utilities which are proposing to use Cd-Te Panels ( I think from First Solar).Note both of these energy utilities are small and might face problems in fund raising and execution.The firms shortlisted for the Solar Thermal Projects don’t inspire much confidence either.The selection procedure and how the subsidy will be disbursed has ran into controversy with accusations of bias and partiality.WA has not gotten any projects while Queensland province has gotten most of the projects.The firms shortlisted have also come under fire as they don’t have much experience.Not much information on how the firms were shortlisted but these companies are definitely not the best or cheapest by a big margin.Australia has generally made a mess of promoting renewable energy with New South Wales cutting feed in tariffs sharply after giving an overly generous subsidy.The Solar Flagship Program looks like an expensive mistake in the making if it comes to fruition.

Solar PV Technology have made a huge advance in the last 2-3 years leading to a demand explosion with more than 100% growth forecast this year.Crystalline PV Technology as well as Thin Film Technology like CIGs and CdTe have reduced their costs drastically.While Solar PV still requires generous government subsidies for their growth,grid parity has come very close.Solar PV Technology has become economically competitive in parts of Italy where a unique combination of high electricity rates and sunshine have made Solar PV Technology very attractive.Costs are being reduced at more than 10% per year which would make Solar PV competitive in 2-3 years in most parts of the world.However mainstream and reputed forecasters and companies like Boston Consulting Group remain blind and ignorant to this.BCG in a recent report has said that biofuels and Concentrated Solar Thermal (CSP) Technology will become competitive.I have issues with both of these technologies.

California and the Federal Government have recently approved a number of big Solar Thermal Plants totaling around 2800 MW.These plants utilize Concentrated Solar Thermal (CSP) Technology and uses mirrors and towers instead of normal PV panels.The haste with which these plants are being permitted and approved is mainly due to the expiry of the Treasury Grant Scheme by end of 2010.According the the American Stimulus rules,only Green Projects which have broken ground or spent 5% of their costs would be eligible for the 30% Cash Subsidy.6 Huge Solar Thermal Plants have been approved with the biggest Blythe plant being the most recent.The capital costs for these plants are extremely high at around $6/watt which makes me question their economics.PV panels can be installed at around $3-3.5 /watt which is around 40-50% lower.Despite the higher capacity factors for Solar Thermal Plants and their ability to store energy for a short period,the cost difference is too large.
