Abstract The main objective of the paper is to investigate the feasibility of small-scale grid-connected PV systems with various PV technologies (mono-crystalline silicon and poly-crystalline silicon) and sun-tracking modes including fixed tilt and 2-axis systems for rooftop households in Amman, Jordan. A case study is applied to Al Jama’a and Abu Nusir, Amman, Jordan. Typical households were chosen for this region to establish a load profile according to monthly electrical bills. The results show that the annual electrical energy from fixed small-scale PV panels tilted at an optimal angle was ranged from 3499.04kWh to 8811.62kWh, while the annual electrical energy from the PV tracking system was within the range of 4788.05-12128.30kWh. This amount of energy output would contribute significantly to reduce fossil fuel consumption and CO2 emissions in the country. Moreover, it is found that the highest energy consumption can be covered by PV systems is recorded in winter. Also, the average energy production cost is ranged from 0.0444-0.0530$/kWh for all proposed systems based on the financial assumptions used in this study. It is concluded that the small-scale grid-connected rooftop PV systems are found to be economically justifiable.

Heating Medium

Evacuated-tube solar collector (ETSC) is developed to achieve high heating medium temperature. Heat transfer fluid contained inside a copper heat pipe directly affects the heating medium temperature. A 10 mol% of ethylene-glycol in water is the heat transfer fluid in this system. The purpose of this study is to modify inner structure of the evacuated tube for promoting heat transfer through aluminum fin to the copper heat pipe by inserting stainless-steel scrubbers in the evacuated tube to increase heat conduction surface area. The experiment is set up to measure the temperature of heat transfer fluid at a heat pipe tip which is a heat exchange area between heat transfer fluid and heating medium. The vapor/ liquid equilibrium (VLE) theory is applied to investigate phase change behavior of the heat transfer fluid. Mathematical model validated with 6 experimental results is set up to investigate the performance of ETSC system and evaluate the feasibility of applying the modified ETSC in small-scale industries. The results indicate that the average temperature of heat transfer fluid in a modified tube increased to 160.32 °C which is higher than a standard tube by approximately 22 °C leading to the increase in its efficiency by 34.96%.

Solar Thermal Collector

Increasing focus on alternative energy sources has produced significant progress across a wide variety of research areas. One particular area of interest has been solar energy. This has been true on both large and small-scale applications. Research in this paper presents investigations into a small-scale solar thermal collector. This approach is divergent from traditional micro solar photovoltaic devices, relying on transforming incoming solar energy to heat for use by devices like thermoelectrics. The Solar Thermal Collector (STC) is constructed using a copper collector plate with electroplated tin-nickel selective coating atop the collector surface. Further, a unique top piece is added to trap thermal energy and reduce convective, conductive, and radiative losses to the surrounding environment. Results show a capture efficiency of 92% for a collector plate alone when exposed to a 1000 W/m2 simulated solar source. The addition of the top “glazing” piece improves capture efficiency to 97%. Future work will integrate these unique devices with thermoelectric generators for electric power production. This will yield a fully autonomous system, capable of powering small sensors or other devices in remote locations or supplementing existing devices with renewable energy.
