TL;DR: In this article, the authors present a wide variety of solar technologies of varying maturities that can, in most regions of the world, contribute to a suite of energy services and offer significant potential for near-term and long-term climate change mitigation.

TL;DR: In this paper, the authors make the case for grid-connected PV generation in Brazil, showing that with the declining costs of PV and the rising prices of conventional electricity, urban populations in Brazil will also enjoy grid parity in the present decade.

TL;DR: In this article, the authors presented operational results of a 11-07 kWp grid-connected photovoltaic system made up of eight groups with different relationships between the inverter's rated power and the PV generator's maximum power (P 0 Inv /P 0 PV ).

TL;DR: The experience curve trend for photovoltaic modules for electricity generation is updated and the results reinforce the importance of energy technology policy on contributing towards making new technologies commercially competitive.

TL;DR: In this paper, the authors present a methodology that estimates the shading factor and irradiation on a three-dimensional model of a receiving surface in an urban environment, where the main innovations introduced by this methodology are the building of a shading matrix composed by direct shading factor values around the whole sky dome and the analysis of the shading impacts on direct beam, isotropic diffuse, circumsolar diffuse and horizon brightening diffuse solar radiation components.
