“…Solar Home Systems are quite popular throughout the off-grid rural areas in the developing world. Although very successful as a primary step towards energy access, the main criticism levelled against them is the low power output that cannot accommodate many of the household gadgets [28][29][30][31]. As a consequence, there is much discussion about the inclusion of economic activities beyond the capacity of a regular solar home system for lights [32,33].…”

This paper presents the feasibility of using solar photovoltaics (Solar PV) as the energy source for cooking with special focus on the loss mechanisms and possible remedial measures. If the heat loss is minimized, to reduce the temperature losses, it is possible to cook with a low power source less than 500 W. A slogan has been adopted by the researchers—‘It is temperature that cooks food not heat’, meaning that it is not the flow of energy that cooks food, but rather, that food is cooked when held at a key temperature for a time. The slogan draws attention to the core concept that if heat loss is minimized, maintaining the temperature inside the cooker and the cooking pan, then the cooking process becomes very energy efficient. The paper considers ways to maintain temperature, but with due reference to the ‘art of cooking’, those all-important cultural processes that determine how meals are made. A prototype solar home system e-cooker was designed, fabricated and tested for cooking different foods in Bangladesh. Experimental results are presented to show that cooking is possible using much less power and energy than is commonly thought. A cost analysis is also presented to show that such a cooker can be cost effective in off-grid areas if connected to a properly designed Solar Home System.

“…However, lithium battery solutions are becoming increasingly more common due to their lower overall lifetime cost and stable field performance. A side-by-side comparison of lead vs. lithium for off grid power is found in [2] where lead-based battery systems are found to be implemented more often based on their lower initial cost. However, the lithium-based battery systems are ultimately found to be lower in overall levelized cost of energy (LCOE) due to their longer life.…”

In this communication, the measured behaviour of a lead-acid battery bank within a stand-alone residential solar photovoltaic (PV)-genset-battery hybrid power system in Canada is presented and discussed. In order to capture rare field-based battery performance data, a newly commissioned lead-acid battery bank was equipped with a battery monitoring device capable of logging voltage, current, temperature and amp-hours every 30 s for the life of the battery. The measured data captures a severe loss of battery capacity due to a combination of short-term deep discharge and extended partial state of charge operation—conditions not unusual during winter season PV-genset-battery hybrid power system operation. Subsequent manual override of the system control set points to encourage gradual battery overcharge are shown to recover the lead-acid battery bank’s performance over the following three months. Limitations of the power conversion system’s battery management approach are discussed and a novel closed loop control system for improving lead-acid based PV-genset-battery hybrid system performance is rationalized and proposed for further research.

“…Considering the important role energy storage systems have in the feasibility of the complete PV model design, in the last decade particular attention was paid to the development of a safer storage solution regarding battery management [9]. Comparison of off-grid power supply systems using lead-acid and lithium-ion batteries is presented in several research papers [10][11][12]. By late 2015, several manufacturers such as Tesla Motors, NEC and Panasonic, introduced their improvements in energy storage devices to the PV sector [13].…”

The aim of this paper is to find an optimal size of different components of an off-grid PV system in the HOMER software with different types of batteries (lead-acid batteries and lithium-ion batteries). The proposed model shows the optimal size of the off-grid PV system for a holiday cottage with regard to eligibility criteria for various types of batteries and the net present cost (NPC). The observed off-grid PV system consists of PV modules, a load, a converter and batteries and it is modelled in the HOMER software. The load is modelled with a daily load diagram for the holiday cottage. For lead-acid and lithium-ion batteries the optimal size of different components of an off-grid PV system for five different scenarios (in respect of the price and life-time) is obtained. In addition, the optimal size of the presented model with respect to different values of capacity shortage ranging from 0% to 5% is presented
