“…A closer look at one type of module (Chinese c-Si) shows the dramatic change in the price curve since 2008 (Figure 2). Historically, modules had a share of around 60% of the total PV system cost (Wang et al, 2011), but due to the extraordinary decline in module prices since 2008, its share in the total installed system cost has since decreased (Hoium, 2011). BOS components are now the majority share of the total capital cost-per-watt and therefore represent one of the main potential sources of further PV system cost reductions (Farrell, 2011a).…”

While the economic feasibility of a particular energy generation project is typically evaluated by metrics, such as ROI or IRR, the LCOE is most commonly used by policy makers as a long term guide to the competitiveness of technologies 9 .…”

Abstract:We briefly consider the recent dramatic reductions in the underlying costs and market prices of solar photovoltaic (PV) systems, and their implications for decision-makers. In many cases, current PV costs and the associated market and technological shifts witnessed in the industry have not been fully noted by decision-makers. The perception persists that PV is prohibitively expensive, and still has not reached 'competitiveness'. We find that the commonly used analytical comparators for PV vis a vis other power generation options may add further confusion. In order to help dispel existing misconceptions, we provide some level of transparency on the assumptions, inputs and parameters in calculations relating to the economics of PV. The paper is aimed at informing policy makers, utility decision-makers, investors and advisory services, in particular in high-growth developing countries, as they weigh the suite of power generation options available to them.

“…Research has found that PV modules with higher efficiency lead to systems with lower levelised costs [23]. The main aim for the solar industry in the future is to further reduce production costs through technological innovations and improvements and increasing the performance ratio of PV [24].…”

This paper explores the photovoltaic (PV) industry in the United Kingdom (UK) as experienced by those who are working with it directly and with consideration of current standards, module efficiencies and future environmental trends. The government's consultation on the comprehensive review for solar PV tariffs, proposes a reduction of the generation tariff for PV installations in the UK of more than 50%. The introduction of the Feed-In Tariffs scheme (FITs) has rapidly increased deployment of PV technologies at small scale since its introduction in April 2010. The central principle of FIT policies is to offer guaranteed prices for fixed periods to enable greater number of investors. A financial analysis was performed on two real-life installations in Cornwall, UK to determine the impact of proposed cuts to the FIT will make to a typical domestic PV system under 4kW. The results show that a healthy Return on Investment (ROI) can still be made but that future installations should focus on off-setting electricity required from the national grid as a long term push for true sustainability rather than subsidised schemes. The profitability of future installations will have to be featured within inservice and end-of-service considerations such as the feed-in tariff, module efficiencies and the implications of costs associated with end-of-life disposal.

“…The model has been developed and provided by the US National Renewable Energy Laboratory (NREL) [20]. It has been used to model and simulate solar water heating [21], concentrating solar power (CSP), solar PV, wind, and geothermal power projects [20,22]. Finally, the two types of SWH technoeconomic performance in light of Inland's solar potential were compared, and the extent of SWH penetration in the existing energy system and associated electricity savings were demonstrated and discussed.…”

The aim of this paper is to assess solar potential and investigate the possibility of using solar water heating for residential application in Inland Norway. Solar potential based on observation and satellite-derived data for four typical populous locations has been assessed and used to estimate energy yield using two types of solar collectors for a technoeconomic performance comparison. Based on the results, solar energy use for water heating is competitive and viable even in low solar potential areas. In this study it was shown that a typical tubular collector in Inland Norway could supply 62% of annual water heating energy demand for a single residential household, while glazed flat plates of the same size were able to supply 48%. For a given energy demand in Inland Norway, tubular collectors are preferred to flat plate collectors for performance and cost reasons. This was shown by break-even capital cost for a series of collector specifications. Deployment of solar water heating in all detached dwellings in Inland could have the potential to save 182 GWh of electrical energy, equivalent to a reduction of 15,690 tonnes of oil energy and 48.6 ktCO 2 emissions, and contributes greatly to Norway 67.5% renewable share target by 2020.
