The effect of 12 different combinations of diffuse–global correlations and tilted surface radiation models on the accuracy of PV output simulation of a grid-connected photovoltaic (PV) system was studied using statistical methods. A site specific diffuse–global correlation was developed...

The impact of photovoltaic (PV) array size, orientation, inclination, load profile, electricity buying price, feed-in tariffs, PV/inverter sizing ratio ([`]sizing ratio') and PV/inverter cost ratio ([`]cost ratio') on the economic viability of a grid-connected PV system was investigated using a...

Renewable energy generation of electricity is advocated as a means of reducing carbon dioxide emissions associated with the generation from fossil fuels. Whilst it is true that renewable sources do not generate significant carbon dioxide whilst producing electricity, as with fossil-fuelled...

The current research seeks to maintain high photovoltaic (PV) efficiency and increased operating PV life by maintaining them at a lower temperature. Solid-liquid phase change materials (PCM) are integrated into PV panels to absorb excess heat by latent heat absorption mechanism and regulate PV...

The performance of a novel heat exchanger unit (‘Solasyphon’) developed for a solar hot water system was experimentally investigated under indoor and outdoor operating conditions. The ‘Solasyphon’ can be easily integrated to an existing single-coil hot water cylinder avoiding the need...

The internal temperatures of 25 households in Northern Ireland were measured in each house at four locations: the bedrooms, living rooms, halls and kitchens, and analysed on seasonal, monthly and daily bases. In 80% of the homes the winter average daily temperature was between 15 °C and...

The performance of a novel heat exchanger unit ([`]Solasyphon') developed for a solar hot water storage system was experimentally investigated. The [`]Solasyphon' is a simple [`]bolt-on' heat exchange unit that can be integrated externally to a traditional single-coil hot water cylinder (HWC)...
