“…In recent years much research on outdoor measurements of PV systems has been done, but the majority of them refer to warm climate conditions [21][22][23]. Nonetheless, spreading of PV technology all over the world implies the need for this kind of study also in locations characterized by lower insolation level such as temperate climate [24,25].…”

This study presents a comparative analysis of energy production over the year 2015 by the grid connected experimental photovoltaic (PV) system composed by different technology modules, which operates under temperate climate meteorological conditions of Eastern Poland. Two thin film technologies have been taken into account: cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS). Rated power of each system is approximately equal to 3.5 kWp. In addition, the performance of a polycrystalline silicon technology system has been analyzed in order to provide comprehensive comparison of the efficiency of thin film and crystalline technologies in the same environmental conditions. The total size of the pc-Si system is equal to 17 kWp. Adequate sensors have been installed at the location of the PV system to measure solar irradiance and temperature of the modules. In real external conditions all kinds of modules exhibit lower efficiency than the values provided by manufacturers. The study reveals that CIGS technology is characterized by the highest energy production and performance ratio. The observed temperature related losses are of the lowest degree in case of CIGS modules.

Due to the variable nature of the photovoltaic generation, energy storage is imperative, and the combination of both in one device is appealing for more efficient and easy-to-use devices.Among the myriads of proposed approaches, there are multiple challenges to overcome to make these solutions realistic alternatives to current systems. This paper classifies and identifies previous efforts to achieve integrated photovoltaic storage devices. Moreover, the gaps and future perspectives are analysed to give an overview of the field, paying attention to low-power devices (<10 W) as well as high-power devices (>10 W). We focus on devices that combine solar cells with supercapacitors or batteries, providing information about the structure, materials used, and performance. On the one hand, small power devices must concentrate on including power electronics to increase the efficiency of the system as well as ensuring a safe operation; likewise, more attention should be drawn to validate the feasibility of novel concepts by carrying out more realistic and standardised tests, including long-term testing. On the other hand, high-power devices must be researched thoroughly to evaluate the impact of high temperatures on energy storage and solar module ageing; furthermore, optimum system sizing is a relevant topic that deserves attention and its relation to modular solutions. This critical literature review serves as a guide to understand the characteristics of the approaches followed to integrate photovoltaic devices and storage in one device, shedding light on the improvements required to develop more robust products for a sustainable future. KEYWORDS battery, one device, PV-storage integration, solar-battery integration, solar energy, supercapacitor 1 INTRODUCTION Solar photovoltaic (PV) energy generation is highly dependent on weather conditions, making solar power intermittent and many times unreliable. Moreover, energy demand is widespread during the day, and solar energy is available for few hours, provoking a mismatch between demand and supply. These two issues are the driving force behind the use of energy storage (ES) devices, which help decrease the fluctuations from the generation side but also provide the possibility of performing ancillary services. Consequently, it is fundamental to find the most appropriate energy storage device for particular applications and operational conditions.According to the characteristics of ES devices, the criterion that defines when the energy is stored and utilised may vary, even for the same component. Some ES devices can supply power during extended periods (hours, days), while others are more suitable for shorter periods of operation (seconds, minutes). For instance, rapid changes in PV power due to rapidly changing illumination conditions can be smoothed using supercapacitors (SCs); they deliver power when solar supply is scarce, so the load is still satisfied. For devices with lower self-discharging values like electrochemical cells (batteries), the electrical energy produced by...

“…In the case of static physically integrated PV battery systems, such as the PBIM, several studies have touched upon the energy management system and system architectures. According to [18], several commercial components can be picked based on the characteristics of the systems and coupled to operate the device. One element optimizes the PV output, while the charging and discharging processes are controlled in two different power stages.…”

Energy Management System for the Photovoltaic Battery Integrated Module

Given the complementary nature of photovoltaic (PV) generation and energy storage, the combination of a solar panel and a battery pack in one single device is proposed. To realize this concept, the PV Battery Integrated Module (PBIM), it is fundamental to analyze the system architecture and energy management. This paper focuses on selecting a suitable architecture among the different options, while also indicating the control strategy that the converters must follow to ensure appropriate performance. Also, several modes of operation for the complete system are introduced to implement energy management. For the selected DC architecture, two case studies, viz. off-grid and peak-shaving for a grid-tied system, were employed to characterize the response of the model demonstrating its utility to perform maximum power-point tracking, excess solar power curtailment, and battery charging and discharging. The proposed control and system architecture prove to be feasible for a PV Battery Integrated device such as PBIM.
