    European PV demand will be the key swing factor for final global PV demand during 2013. Sound familiar? Demand from established ‘Western’ PV territories (Europe and North America) may comprise as little as 49% of global demand, but as much as 57%. Whether we end up closer to the upper end of this range or the lower range will ultimately shape the outcome of the PV industry this year.

Few companies are adding or updating capacity, both on the crystalline silicon and thin-film PV fronts, and tool firms’ bookings (let alone billings) remain very light.

    By Richard Keiser - 21 August 2012, 13:35 | 4

    Company executives and analysts alike face a number of difficulties in answering this very important question. To reach the answer requires strong fundamentals in solar PV economics. This, however, is unfortunately not enough. The data necessary to answer the question are difficult to collect and even more difficult to structure and maintain. Further, the data are highly dynamic: US incentives change in structure, decrease or expire and electricity prices change in both magnitude and composition. All of these variables affect a market’s attractiveness, which itself can change substantially over time.

    The successful deployment of renewable energy, including solar, is critical for America’s future energy supply. Recently, a lease financing mechanism has been one of the most powerful drivers of solar power deployment in the US. Though solar leases have helped grow the industry, the authors contend that they come at an inflated and higher than intended cost to the US taxpayer compared to cash purchases. Further, if these inflated taxpayer costs become politicized, the industry may suffer another setback.

    The industry has now had a chance to take stock of the US Department of Commerce’s announcement that it will impose an import tariff on PV cells, or PV modules that contain cells, manufactured in China. The preliminary findings of the anti-dumping case, which was initiated in October 2011 when a group of PV manufacturers, led by Germany’s SolarWorld, filed a trade complaint, revealed that a tariff of approximately 31% would be levied against a specified group of the largest Chinese cell manufacturers and a rate of 249% against all other Chinese manufacturers. This was in addition to March’s introduction of less severe countervailing duties to negate the allegedly unfair subsidies that Chinese suppliers benefit from.

    By Marina Temchenko - 20 February 2012, 19:22 | 1

    PV is a global market, but there are currently no global certification standards. As the module market space continues to expand in size and numbers of manufacturers, global regulatory groups are challenged to write and enforce global material and module standards. Currently material and module manufacturers are forced to certify, and develop, according to multiple regional requirements. For the material developer, regulatory approval on both materials and modules takes upwards of a year. As it cannot be conducted contiguous to other development steps, this is a ‘direct add-on’ to the time lag between innovation investment and the profit return.

    By Ash Sharma - 16 January 2012, 16:45 | 2

    The simple answer is yes. Certainly enough modules and inverters were sold, and if installations really did hit 7.5GW in Germany then this would undoubtedly mean that at least 26GW was installed globally last year, with Germany retaining its position as the largest market, followed closely by Italy. We’re still finalising our data for 2011, but we now estimate up to 26.5GW could have been installed last year following the phenomenal year-end rally in Germany. This would have meant an incredible 10 GW was installed in the last quarter of the year – the first time this has ever happened and more than the whole amount installed in all of 2009!

    According the Federal Network Agency, only 3.35 GWp of PV systems were installed in Germany in the first 9 months of 2011. In comparison to last year, this represents a market volume decrease of 40%. In 2010, 5.53 GWp were installed in September alone. Market experts currently estimate that the total additional installations in 2011 will amount to 5.5 GWp. This would mean that the German market would be in a state of regression for the first time, at 25% below the installation rate of the previous year.

In this game, a hypothetical person is given one penny (or one euro cent) on the first day, two pennies on the second day, four pennies on the third day, etc., and then asked to guess the total value of the pennies at the end of one month. Very few people guess correctly – US$21 million – or appreciate that 75% of that value is created on the last two days.
