The rise in the surface temperature of a photovoltaic (PV) module due to solar heat significantly reduces the power generation performance of the PV system. Photovoltaic-Thermal (PVT) systems are being developed to overcome these limitations. The study discusses predicting power generation in PV and PVT systems.
Solar PV alone is set to increase its share of total electricity generation from 5% in 2023 to 17% in 2030 and 37% by 2050, while wind will grow from 8% in 2023 to 21% by 2050 (Figure 2).

The power and energy capacity of the battery bank increase along with higher renewable energy penetration. The power capacity and discharge duration of the battery bank is 10% of the wind-PV power installed capacity and 1 h of the 1st batch, they further increase to 15% and 4 h of the rest of the batches.

At the same time, battery storage, which is recently being placed by energy consumers alongside photovoltaics, continues to fall in price. Domestic and community loads may be combined utilizing central battery storage and shared solar power through an integrated grid or microgrid system.
If the PV system is grid-connected, batteries can reduce the fluctuation of PV output or provide economic benefits such as demand charge reduction, capacity firming, and power arbitrage. The work in analyzes the relation between available battery capacity and output smoothing, and estimates the required battery capacity using simulations.
The battery gets charged from the PV generation only when there is surplus PV generated electric power and the battery can still be charged, and gets discharged to supply the load only when the load cannot be met by PV generated electric power and the battery can still be discharged.
For a properly designed photovoltaic system, the energy self-consumption can be up to 90.19%, while self-sufficiency can be up to 82.55% for analysed cases. As an outcome, a large sample size with a variety of setups is recommended for a thorough examination of self-sustainability.
Our setting is shown in Fig. 1. PV generated electricity is used to supply loads: on one hand, if there is surplus PV generation, it is stored in a battery for later use or dumped (if the battery is fully charged); on the other hand, if the PV generation and battery discharging cannot meet the demand, electricity is purchased from the grid.
If the PV generation is not ideal, i.e., there are fluctuations due to clouds or precipitation, the E max c value in Proposition 6 based on ideal PV generation naturally serves as an upper bound on E max c for the case with the non-ideal PV generation.
