However, the intermittent nature of solar energy results in a high dependence on weather conditions of solar cells. Integrated solar cell-energy storage systems that integrate solar cells and energy storage devices may solve this problem by storing the generated electricity and managing the energy output.
The integrated system achieved an overall solar energy conversion and storage efficiency of 14.5%. Later on, the same group used DC-DC converter to elevate the low-voltage PV voltage to over 300 V and charged the high-voltage NiMH battery pack, resulting in an integrated system with a high solar to battery energy storage efficiency.
While not a new technology, energy storage is rapidly gaining traction as a way to provide a stable and consistent supply of renewable energy to the grid. The energy storage system of most interest to solar PV producers is the battery energy storage system, or BESS.
The energy storage system of most interest to solar PV producers is the battery energy storage system, or BESS. While only 2–3% of energy storage systems in the U.S. are BESS (most are still hydro pumps), there is an increasing move to integrate BESS with renewables. What is a BESS and what are its key characteristics?
The system utilizes a 6.8kW PV array and a 5kW electrolyzer powered by surplus solar power to produce hydrogen, which is then stored in a hydrogen tank via a compressor. In periods of high energy demand, when PV generation is not sufficient, the green fuel is used to produce electricity via a 1.24kW fuel cell system.
The simplest way to integrate the energy conversion and storage units together is to connect them by wires. [21, 23] For example, Gibson and Kelly reported a combination of iron phosphate type Li-ion battery and a thin amorphous Si solar cell. The integrated system achieved an overall solar energy conversion and storage efficiency of 14.5%.
