Photovoltaic (PV) panels account for a majority of the cost of photovoltaic thermal (PVT) panels. Bifacial silicon solar panels are attractive for PVT panels because of their potential to enhance electrical power generation from the same silicon wafer compared with conventional monofacial solar panels. This paper examines the performance of air-based bifacial PVT panels with regard to the first and second laws of thermodynamics. Four air-based bifacial PVT panels were designed. The maximum efficiencies of 45% to 63% were observed for the double-path-parallel bifacial PVT panel based on the first law of thermodynamics. Single-path bifacial PVT panel represents the highest exergy efficiency (10%). Double-path-parallel bifacial PVT panel is the second preferred design as it generates up to 20% additional total energy compared with the single-path panel. However, the daily average exergy efficiency of a double-path-parallel panel is 0.35% lower than that of a single-path panel.

The characterization of thermoelectric modules for power generation applications has only received minimal attention by researchers. This paper describes the development of a test stand for the characterization of the thermoelectric power modules. The test stand has the ability to provide constant temperatures on the hot and cold side of thermoelectric modules and measure the amount of electrical power generated. Great care was taken to provide a uniform temperature on both the hot side and cold side of the module, with the hot side having the capability to provide temperatures of up to 600°C and the cold side able to be maintained at room temperature. The system is able to deliver a controlled heat flux of 140 kW/m2 to a thermoelectric module. A data acquisition system was developed to record the electrical performance of tested modules under a wide range of operating temperatures regulated by the control system. Using the collected data it will be possible to compare many modules and evaluate their performance with one another as well as provide module power generation parameters which can be useful for thermoelectric system design. This project was commissioned through the RIT Multidisciplinary Senior Design program as a capstone to the undergraduate degree curricula.

The cost of solar-generated electricity and battery costs have been decreasing significantly. These developments can be combined to introduce solar-powered charging networks with demand management prices (DMP) to enable electric vehicle (EV) customers to help utilities to manage renewable energy. As solar-generated electricity becomes the cheapest source of power, the need to increase demand for electricity during the day can be met by charging EVs at an attractive DMP in parking lots with solar panels and charging stations that are connected to the electrical grid. The demand for electricity can be managed and controlled by the utility with the goal of increasing demand for power as needed so that all electricity that is generated can be sold. The proposal is to introduce a new DMP rate that is only implemented when the utility wants to increase demand and sell power at this low rate in order to make full use of the supply. As utilities strive to reach 100% renewable electrical power to serve a society transported by EVs, cooperative plans to make good use of batteries in EVs for managing the electrical grid will become more important.

Abstract This paper presents the design of an innovative wave energy converter, namely, Electrical Power Generation - WEC Device System from the Swell, abbreviated as WECFS. This WEC device has been registered for a patent in the Spanish Office of the Patents and Brands (OEPM) with the registration number of the innovative utility model-Patent Model: 202131440(5). The study reported in this paper endeavours to demonstrate the technical feasibility, functional mechanical-kinematic behaviour, and the performance of the proof-of-concept WEC device system, in order to determine their energy extraction capacities and functionalities. The overall energy extracted with eight electrical generators A/C is 0.185 MWatts calculated analytically. The levelized cost of energy is a very important metric in determining whether to move forward with the project, where the cost of energy target has been as cheap as $0.07kWh; this value of LCOE could be improved with optimisations on the practical design parameters. This preliminary study investigates the factors influencing standardized and industrialized for the new WEC device system and can be used to guide the optimization of this type of device technology.

Partnership Program

Rejosari Village has enormous potential, namely there are many abundant rice fields around the settlement. Rejosari Village is located in Kebonsari District, Madiun Regency. Farmers in Kebonsari village have used a water pump that is used in the rice field irrigation system. However, until now many farmers still use PLN as the main source in running electric motors for irrigation systems. So that farmers often experience power outages due to lack of electrical power. Community service activities through a partnership program for farmer groups in Rejosari Village, Kebonsari District, Madiun Regency are focused on making Automatic Transfer Switch (ATS) panels to convert electrical energy source switches from PLN to sources of solar energy from solar panels. This ATS panel contains a switch that can replace the source of electrical energy in an electric motor that was originally from PLN into an energy source from the Solar Panel. The hope is that with this community service program, farmer groups can obtain electrical energy to power the irrigation system and not depend on PLN. This PKM can also reduce the cost of electricity rates incurred by farmers.

Lobular Panniculitis

Background:In medical practice lobular panniculitis-lipodermatosclerosis (LDS) is becoming more and more common. It is manifested by degenerative-dystrophic changes in subcutaneous fat (SCF) and occurs more often in middle-aged women affected by chronic venous insufficiency.Objectives:to evaluate the effectiveness of mesotherapy (MT) and shockwave ultrasound therapy (UST) for LDSMethods:among 539 patients referred to the V.A. Nasonova Research Institute of Rheumatology with the referral diagnoses of erythema nodosum or panniculitis 8.5% (46) of patients (44 women, 2 men) aged 18 to 82 with overweight (32) LDS with the disease duration of 11,8±6.4 months was verified. Patients were randomized into two groups of 23 patients each: group I received daily MT (10 sessions) therapy with drugs that have antioxidant, anti-inflammatory, lymphatic drainage and lipolytic effects, and 3 MHz UST of the node area twice a week (5 sessions). In group II MT was performed daily with 9% Natrii chloridum solution at a dose comparable to group I. The control methods included general clinical examination (characterization of induration on the lower legs with an assessment of the effect of pain pressing according to visual analogue scale (VAS pain), general blood and urine tests and ultrasound with elastography (USE) of the compaction. The main stages of control: initial (T0), after 14 days (T1), 1 month (T2) and 3 months (T3).Results:before treatment 38 patients with LDS demonstrated asymmetric (83%) inflammation of SCF of the lower legs (100%) on its medial surface (91%). LDS regressed faster with normal body mass index (p = 0,04). In all patients of group I, after a course of physiotherapy a positive trend was registered, that is a decrease in VAS pain intensity (T0 50±18 mm; T1 35±11 mm), decrease in diameter (T0 6±2.2 cm; T1 4.5±1, 7 mm) and color intensity of the node (p<0.002), SCF thickening which results in “lumping” with macrovascularization according to USE, and decrease in ESR and CRP. In 44% of cases the treatment effect increased to T2 (p <0.05). After 3 months of observation, 15 patients required a second course of physiotherapy. In group II a positive clinical effect was registered for T2 in 14 patients (60.8%) and for T3 in 19 patients (83%) (p<0.05). Over the entire observation period LDS recurrence was registered in 19 patients (41%), the median of recurrence was 3 [1; 6] months, mainly in patients of group I. Recurrence was associated with node fusion into conglomerates (OR 4.33, 95% CI 1.05-17.8; p = 0.037). MT and UST were tolerated well, no side effects were detected.Conclusion:the use of MT with 9% Natrii chloridum solution allowed us to achieve positive dynamics in patients with LDS, which significantly reduced the cost of treatment. Further studies are needed to evaluate the significance of these techniques.Disclosure of Interests:None declared
