Rooftop photovoltaic (PV) systems are represented as projected technology to achieve net-zero energy building (NEZB). In this research, a novel energy structure based on rooftop PV with electric-hydrogen-thermal hybrid energy storage is analyzed and optimized to provide electricity and heating load of residential buildings. First, the mathematical model,
The long-term energy storage (energy storage period of more than one month) is necessary. In the baseline scenario, P PV is 0.598, between 0.46 and 0.67, and there is only hourly PV oversupply and daily PV supply without monthly oversupply. Therefore, long-term energy storage is not necessary for the station in this study.
3.3. Optimal Dimensioning of a PV System and an Energy Storage Facility for the Building Considered as Total Load. When considering an energy storage facility in addition to the PV system, the optimization model and calculations given in Section 3.1 have to be adapted.

Solar energy is also available at scale. The global roof surface area suitable for solar PV installation has been estimated at 36 billion m2, or 4.7 m2 /capita, leading to a potential for rooftop photovoltaic of 8.3 PWh/y, roughly 1.5 times the 2015 global residential electricity demand (Gernaat, D.E.H.J., et al., 2020).
The storage is used to consume surplus solar PV power locally during PV peak, and the stored energy is utilized in the evening for the peak-load support. A charging/discharging control strategy is developed taking into account the current state of charge (SoC) of the storage and the intended length of charging/discharging period to effectively utilize the available

Showing that although DERs can provide support to the power distribution system, the support is dependent on the weather (solar irradiance availability) and the availability of energy storage, i.e., without energy storage, roof-top solar can only provide limited support to the distribution grid. This can be observed in Fig. 14, Fig. 15.
There are a number of open-source tools available to evaluate and size residential energy systems that are inclusive of rate tariff, net metering policy, tax incentives, and solar resource, including the Energy Storage Evaluation Tool (ESET) [2], the System Advisor Model (SAM) [3], QuESt [4], and more.The intent of this study is not to replicate the
Physical approaches usually involve developing 3D models to estimate the solar energy received by the roof, This further suggests that there is no need to prepare a very large storage capacity for cost effectiveness. With a target curtailment rate of 5%, 3.8 h, 5.0 h and 6.6 h storage capacities are necessary for a grid with 100%, 90% and

in home energy storage. In 2021, there were 30,246 home en-ergy storage systems installed at a total capacity of 333 MWh. Since 2015, a total of 133,000 battery storage installations have been installed. This suggests that 2 in 13, or 15%, of Australian households with a solar PV also have battery energy storage (BES) [6].
Based on the hourly load profiles we calculated in Figure 4, we estimated the required energy storage capacity in different scenarios of PV curtailment for the Kyushu grid, as presented in Figure 5 B.
