“…Although storing the surplus energy of a solar system seems an obvious decision, the cost of adding batteries is substantial. While several authors suggest a PV/battery system combination for self‐consumption, in this study, it is suggested to use the battery only to store power of the PV system, rejected by the grid, during daytime and unload the battery only during nighttime by injection in the grid, when the PV system is not generating energy.…”

“…In Deutsch and Graichen, a study can be found assessing a high penetration level of PV generation and battery storage in Germany. In de Oliveira e Silva and Hendrick, the cost of self‐sufficiency for a PV battery system is calculated in detail for the Belgian electricity regulatory framework. Typical price levels of 30 to 40 c€/kWh are derived for self‐sufficiency levels of 70% to 80%.…”

“…Most studies address the combination of a PV and a battery system, based on the concept of self‐consumption on a local or house scale, and assess the cost‐effectiveness of such a combination. However, battery storage makes this solution still relatively expensive, compared with the traditional electricity generation technologies . A system with subsidies is required to enable a business case for the combination of PV and battery storage to realize self‐consumption for houses, or alternatively, more complex business models for batteries are needed .…”

“…One hundred percent self‐consumption would require a very uneconomic setup with unrealistic large battery and PV sizing . With more realistic numbers of sizing the PV and battery system, already a high ratio of self‐consumption may be attained . During the periods in which the system does not provide sufficient power, it is most convenient to use the electricity grid.…”

An overall model and scenario for increasing the share of renewable electricity consumption in the Belgium grid is proposed by simulating different PV and home battery capacities. The model is balancing the electricity generation of these renewable sources on an hourly basis with the historical consumption profiles of 2014, 2015, and 2016 to estimate how much renewable energy can be consumed directly. The model considers the problem of potential overloads on the low voltage grid, by limiting with curtailment the total PV injection on the low voltage grid to a level that can be currently sustained. A simple algorithm for grid injection limitation of this curtailment during daytime and nighttime is proposed, with and without the use of batteries. The share of renewable electricity consumption is calculated, investigating the impact of battery sizing and different levels for the power injection limit. Above a certain level, additional battery capacity has no effect. With increasing total PV deployment, the optimal power injection limit is reduced. A realistic and effective deployment scenario for renewable electricity from wind and PV is developed (up to 9 GW wind and 50 GWp PV for the Belgian case). It is possible to reach a share of consumed renewable electricity of almost 50% with a curtailment of 9% without the use of batteries. With higher PV deployment and a minimal amount of home battery capacity (1.5 kWh/kWp), a 70% share of consumed renewable energy is realized, with a curtailment of less than 20%.

Summary As a global common trend for fossil fuels independence, renewable energy plays a great role to save a clean source of energy. As a result of the high solar energy potential in Egypt, successive incentive polices had been introduced by the Egyptian electricity authority to encourage the deployment of small‐scale residential rooftop photovoltaic (PV) systems. This paper explores the impacts of installing a grid‐connected PV battery system from both technical and economic point of view under the existing incentive policy and energy purchasing and selling price in Egypt. The Egypt case is considered as a case study. The study investigates the current Egyptian Incentive Policy situation and criteria for high electricity load profile. The economic evaluation of various sizes of the PV battery system is carried out based on different economic measures such as net present value (NPV), self‐sufficiency (S‐S), and electricity bill savings. The methodology is based on the assessment of different technical and economical indices as well as on performing sensitivity analysis. A MATLAB code was purposely developed and implemented to evaluate the economic effect of the installed system considering the effect of battery capital cost and discount rate variations. A net energy metering (NEM) incentive policy is suggested to increase and maximize the financial profits from installing PV battery system and increase the independency from the utility grid. The results showed that doubling the sellback power price to $0.089/kWh instead of $0.04/kWh will decrease the profitable PV system size to the half and will increase the NPV to the double. Under FiT incentive policy, installing 25 kWp PV system can achieve 50% of S‐S and adding 12.5 kWh of batteries will increase it to 75%, while under the NEM incentive policy, installing 15 kWp PV system can achieve 47% of S‐S and the 75% S‐S can be achieved by adding 15 kWh of batteries.

The photovoltaic (PV) system has a very significant growing global trend and its role is essential in combating climate change. However, its intermittent nature requires integration with a battery energy storage system (BES). This work proposes an economic analysis based on net present value (NPV) for an integrated PV + BES system in a mature market (Italy). The analyses are applied to different policy (used for both PV and BES) and market (purchase price, selling price) contexts. Results show that the NPV(PV) ranges from 1061 to 7426 €/kW. The work identifies the conditions under which BES is affordable. The required increase in self‐consumption varies in the 14%–35% range. The purchase price and the percentage of energy‐self‐consumption play a crucial role in the profitability assessment of a PV + BES system. Incentive policies based on subsidized tax deductions and subsidies for energy produced and self‐consumed can enable a more sustainable energy future in the residential sector. This work suggests a mix of policy choices: (i) a subsidized tax deduction larger than 50% and a bonus for energy produced and self‐consumed for PV plants; (ii) subsidized tax deduction also for BESs but at a lower value than for PV plants; and (iii) encouraging a recycling industry.
