TL;DR: In this paper, the patterns of electricity consumption were studied for 27 representative dwellings in Northern Ireland, and a clear correlation was found between average annual electricity consumption and floor area, and the difference in the annual demand on the grid between detached and terraced houses is between 24 and 30%.

TL;DR: In this article, a review of recent research in Building Integrated Photovoltaics (BIPV) is presented with the emphases on a range of key systems whose improvement would be likely to lead to improved solar energy conversion efficiency and/or economic viability.

TL;DR: In this article, the authors explored the variation of life-cycle operational and embodied energy and capital cost as a function of building parameters, and showed that additional embodied energy gained over the building life is larger than the operating energy over the same period.

TL;DR: In this paper, the optimum PV/inverter sizing ratio for grid-connected PV systems in selected European locations was determined in terms of total system output, system output per specific cost of a system, PV surface orientation, inclination, tracking system, inverter characteristics, insolation and PV/INverter cost ratio.

TL;DR: In this paper, the performance of a 13 kWp roof mounted, grid connected photovoltaic system in Northern Ireland over a period of three years has been analyzed on hourly, daily and monthly bases.
