“…Solar energy is one of the commonly used renewable energy sources, which has been widely utilized for heating (i.e., solar thermal collectors [8]) and electricity generation (i.e., photovoltaic panels [9]) during past decades. Solar photovoltaic (PV) system has the advantages of modularity, easy maintenance and relatively long lifetime [10]. However, the amount of solar energy is related to the geographical location [11] and the solar radiation conditions are also different between summer and winter [12].…”

“…But the use of batteries, besides the environmental problems, increases the cost of maintenance due to their short lifespan. Ajiwiguna uses a seasonal water storage tank to store water instead of electricity and optimizes the capacity of the main units of the system to achieve the minimal cost of the water treatment system 15 . In addition, Ben Ali has replaced the use of a hydraulic reservoir in tanks with electrochemical batteries for photovoltaic water treatments.…”

Summary This paper investigates the performance of a battery‐less photovoltaic desalination system. Lead‐acid batteries have been removed from the system due to adverse environmental effects, a shorter lifespan, and to reduce the total cost. Due to the lack of a storage device, starting a high current load like an AC compressor leads to electrical instability of the system. The proposed solution for this problem includes using a combination of two high‐capacity electrolyte capacitors, one at the PV terminals and the other at the single‐phase inverter input terminals. Suitable resistive starters have also been sized and added to the circuit to limit the inrush current of capacitors at the energization moment. An analytical procedure has been introduced to design the optimal size of the capacitors and the starter resistors. The results of a 1.1 kW test system show that using two capacitors, 12 000 μf/ 350 Volts as C1 and 330 000 μf/ 50 Volts as C2, at the same time, can handle a starting current of 12 Amps for the starting period of 100 ms of the AC compressor. The maximum voltage drop on the capacitors will be 48 and 17%, which are in the accepted range, and no instability happens.

Stand-alone hybrid energy systems based on solar and energy storage are an effective option for rural areas to meet the load demand. The objective of the current work is to the optimal configuration of a stand-alone hybrid photovoltaic/battery energy storage system with the help of an efficient metaheuristic algorithm, improved harmony search, to supply electrical of a residential load in Iran. The objective function is a minimization of total life cycle cost (TLCC) subject to the reliability index (loss of load probability). The optimal configurations of hybrid systems are compared in respect of different losses of load probability (0 to 20%). Sensitivity analysis and effects of economic parameters based on photovoltaic and battery prices are carried out to study the possibility of the suggested scheme. The results show that, by increasing the reliability index from 0 to 20%, the optimal number of panels and batteries decreases by 52 and 1202. Also, it is found that the TLCC of the system and cost of system components are increased by decreasing of the reliability index value.
