Is energy storage a viable option for utility-scale solar energy systems?

Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.

Can homes share surplus solar capacity & stored energy in a virtual battery?

We present an energy sharing algorithm that enables homes to share surplus solar capacity and excess stored energy in a virtual battery with households experiencing energy deficits and discuss monetary incentives for borrowers and lenders to incentivize such sharing.

Can photovoltaics be used in buildings?

Photovoltaics (PV) application in buildings has been vastly researched, worldwide 3, 4. D’Adamo et al. 5 evaluated that PV has low risk source of solar energy with high economic returns. It is evident that there is an essential need to implement more sustainable ways of generating energy due to the expected shortage of fossil fuels in the future.

How do residents share solar and battery energy?

Note that the residents share only their portion of the community solar or battery energy. The share of solar and battery for each home is determined based on their energy consumption in the previous year, i.e., we assign a solar and battery proportionate to their overall yearly load.

What is community energy storage?

In urban areas, community energy storage serves various purposes including increasing self-consumption, enabling the seamless integration of intermittent renewables, and providing economic incentives (Barabino et al., 2023; Koirala et al., 2018; Zhang et al., 2023).

Can a community-based solar system save energy?

This is because, with larger solar installations, most homes will have surplus energy to lend, which will reduce the need to borrow energy from others. We note that a virtual community-based system can reduce its solar array size by 14.6%, through energy sharing, to achieve 60% energy cost savings compared to a dedicated system.
