“…Other studies such as e.g. Johnstone et al (2010) find little empirical evidence for a strong and positive effect of feed-in tariffs on innovation. 18 We might expect that price-based policy instruments such as feed-in tariffs are more effective if the energy market is open to competition.…”

“…Since the duration over which the feed-in tariffs are paid differs across countries as well as within countries at different times, we decided to use the annuity of the stream of paid tariffs instead of the tariff for the first year as in e.g. Johnstone et al (2010). This enables us to account for the decreasing feed-in tariffs over time which Germany introduced from the very beginning.…”

“…Only recently however, researchers have paid attention to the question about the impact of individual policy instruments on innovation (see e.g. Klaassen et al, 2005;Johnstone et al, 2010). 1 Our study continues to ask how effective environmental policy instruments are in stimulating innovation.…”

SummaryWe study the impact of environmental regulations on the patent activities for wind turbines between 1980 and 2008. We explicitly control for energy market liberalisation and take a potential interaction between liberalisation and policy instruments into account. We find a strong and highly significant effect of environmental tax revenues, which we regard as a proxy for the extent to which energy prices changed in favour of renewable energies, as well as foreign demand for wind turbines on innovation activities. In addition, we find that pricebased policy instruments are more effective in fostering innovations in the wind turbine technology when energy markets are fully open to competition. In contrast, non-price-based policy instruments such as grants or low interest rate loans are largely independent from whether or not energy markets are liberalised.

“…Most models compared in a study [16] set technological progress exogenously by assumption. Examination of the effects of public policies on innovation in the area of renewable energy in a cross-section of OECD countries over the period 1978-2003 finds that the empirical results indicate a strong influence of policies on innovation in renewable energy technologies [17]. A comparison of two CGE models with regard to the modelling of technical change (endogenous/exogenous) and the resulting effects on the impacts of carbon taxes on different industries is presented in [18].…”

This paper brings together the debate on economic impacts of renewable energy (RE) deployment and the discussion on modelling endogenous technological change on the global markets for the different renewable power generation technologies. Economic impacts of RE deployment are still mostly discussed on national level, where different effects have been identified. Recent research for Germany shows positive effects on the macro level and different distributional impacts. High investment in solar photovoltaics (PV) from 2010 to 2012 and induced increases in the RE surcharge are the main drivers. At the same time, cost reductions for wind and solar PV take place on global markets, with global learning curves explaining the cost reductions very well. This calls for better including the international dimension into the modelling. The complex feedback loops between global cost curves and national policies, which react to global learning with some time lags, are not yet integrated into complex economic models. These models have to capture different RE technologies, different industries, either delivering the RE technologies or strongly depending on electricity prices, which are influenced by national support policies and macroeconomic development. As a first step to better understand the role of international markets, assumptions on RE exports based on global scenarios can be used. Results show the importance of global markets at least for the German RE industries. If the international dimension is taken into account, mainly positive economic impacts of further RE deployment can be observed.

“…Many types of research have been made on various renewable energy sources to meet the rise in consumption and price of fuel. The renewable energy includes tidal, the wind, biomass, geothermal and solar energy production [1], [2]. Most of these technologies are at demonstrative stages but shown promissory results to control greenhouse emissions [3].…”

Effect of accumulated dust on the performance of solar PV module

A Solar panel is rated such that it can yield optimum output under Standard Testing Conditions (STC). But due to different environmental factors the efficiency of the panel is reduced gradually after installation. Accumulation of dust on solar PV panel is one such natural phenomenon. When dust accumulates on the PV panel, the temperature of the cells increases which subsequently decreases the open circuit voltage. The short circuit current is also reduced as deposition of dust causes shading on the panel surface. As a result, the output power of the module decreases. In this paper, the effect of dust on the performance of the photovoltaic module has been studied. The increase in temperature due to dust accumulation has been visualized through the thermal camera and the reduction in power has been analyzed through PSpice simulation and experimental data for the different amount of dust accumulated.
