Solar energy is a ubiquitous renewable resource for photovoltaic (PV) power generation; however, higher operating temperatures significantly reduce the efficiency of PV modules, impacting their electrical output and increasing levelized cost (LCOE). This study aims to enhance conventional systems’ annual recovery while reducing LCOE through thermal management using microchannel heat sinks (MCHSs) under forced convection. A 600 W monocrystalline module was analyzed, recognizing an reduction ~20% actual conditions due effects, with surface temperature reaching up 63.76°C without cooling. In addition, analytical calculations were used determine incident solar irradiance 957.33 W/m 2 industrial location in Lahore, Pakistan. Similarly, computational fluid dynamics (CFDs) simulations conducted single dual‐layer MCHSs configurations water as coolant at inlet velocities ranging from 0.01 1.0 m/s. The reduced module’s 63.76 ~25.65°C velocity m/s, achieving 38.11°C. increased 18.33% (without cooling) 22.27%, gain ~4%. improved substantially; configuration by 227,954 kWh/year (about 21.89%) compared no‐cooling scenario, 1,269,131 kWh/year. Furthermore, low 6.27 PKR/kWh over 30‐year operational lifespan lower velocities, demonstrating cost‐effectiveness. Meanwhile, optimal identified between 0.2 0.5 balancing performance economic viability. Finally, this concludes that effectively enhances efficiency, increases recovery, reduces LCOE, contributing sustainable economical integration applications.

This paper aims to broaden the concept of Net Zero Energy Building (NZEB), assessing its suitability emerging grid-based energy sharing models. The exchange between two buildings with shifted load schedules, namely, a new residential NZEB (prosumer) and an existing school building (consumer), is analysed investigate dynamics. are in Southern Italy, region high solar radiation. model calibrated on measured data study performed by dynamic simulation. Three scenarios based design photovoltaic system installed roof have been investigated, i.e., PV peak power designed: satisfy target annual basis; monthly fully exploit available area NZEB. Considering net balances, oversizing leads compensation share non-renewable consumption. However, self-consumption analysis hourly basis shows that increasing size negatively affects rate renewable community, presence only mitigates this effect.

Global warming is an environmental issue that threatens life on Earth. A significant rise in global temperature at the end of century estimated to be 2.4 °C, which necessitates action. The growth energy needs urges scholars/researchers think about developing suitable solutions. key goal achieve zero-net emissions by 2050 accordance with goals outlined Paris Agreement (Climate Accords). To accomplish this, it vital have a strong strategy initially includes high reduction and addresses challenges our planet. Therefore, 2050, aims eliminate from industry zero. It worth noting most consumed comes transport, power generation, industry, buildings. use renewable technology method widely recommended such challenges. Solar has two main technologies: solar photovoltaic (PV) concentrating (CSP), great potential fulfilling needs. This work provides insight into technology's role decarbonisation towards net-zero through wide deployment yield. perspectives technologies can save environment reducing supply, lowering bills, creating job opportunities. Hence, investment other clean will substantially sustainable development coming decades; as forecasted, installation capacity worldwide.

In supporting the phase-out of fossil fuels, Roof Top Photovoltaic (RTPV) deployment has been adopted worldwide as an important step a bottom-up driving pathway citizens' transformation to become net energy producers within community their localized building environment. However, diverse bioclimatic conditions this environment may affect best RTPV implementation. This is facilitated by climate-related characterization and regional adaptation. Hence, built globally function global horizontal irradiation (GHI), local environmental parameters different climatic zones associated technological developments are surveyed. work, we have critically assessed effect on building's overall performance found beneficial over range moderate warm climates. By applying adequate insulation beneath RTPVs, increased heating needs in winter cold climates or higher nighttime cooling summertime can be avoided. To design low-energy buildings, propose analytical framework based space coverage irradiation. Moreover, at elevated temperatures improves efficiency up 20% increases generated electricity 15%. Increasing with emerging technologies could extend decarbonization high-rise buildings measures. accelerate clean transition, rooftop PVs should widely for sustainable solar applications. Combined electrical storage, will allow renewable resources cover large fraction future worldwide.
