What you need to know about commercial and industrial PV + energy storage?

1. What is PV + energy storage?

In recent years, with the growing importance of environmental protection and renewable energy, PV + storage technology has gradually become a hot topic in the global energy field. PV+Storage refers to the combination of solar photovoltaic power generation technology and energy storage technology, by converting solar energy into electricity and storing it, in order to meet the real-time demand for energy and balance the energy supply.

2、Advantages of PV + Energy Storage?

2.1 Make up for the problem of unstable solar electricity production and intermittency of photovoltaic power generation and solve the problem of energy transmission and storage to provide continuous and stable power.

The system solution emergence of photovoltaic + energy storage is to solve the instability and intermittency that exists in photovoltaic power generation. In traditional photovoltaic power generation systems, the generation of electricity fluctuates with the intensity of solar radiation and weather conditions, which cannot meet the continuous supply and stability of energy. Solar power generation takes place during the daytime (roughly between 7:00am-18:00pm), and solar energy cannot be accessed at night or on cloudy or rainy days, while the traditional power grid is unable to effectively store excess energy, resulting in a waste of resources. Photovoltaic + energy storage technology solves this problem. Photovoltaic power generation systems can convert solar energy into electricity and utilize energy storage devices to store the excess energy and release it when needed. This not only ensures the stability and reliability of solar power generation, but also makes energy more flexible. Energy storage technology provides a reliable backup energy source for the solar power system, enabling the PV system to meet the user's real-time demand for energy, while reducing energy losses when transmitting energy.

Note: Solar power laws:

The power of photovoltaic power generation starts to rise slowly when the sun has just risen from 7-9 a.m.; from 10 a.m. to 14 a.m., the power generation peaks due to the high solar altitude angle and better light conditions; subsequently, with the gradual decline of the solar altitude angle, the power generation gradually decreases from 15 a.m. to 18 a.m., and eventually tends to be close to zero.

And peak electricity consumption is usually in the middle of the day and at night. This tends to create an imbalance between power generation and power usage, where there may be excess solar energy during the day and no solar energy at night. Then the storage battery can be a good solution to this problem, storing the excess solar energy during the day and discharging it to the load when there is insufficient solar energy.

2.2 Provide clean electricity and reduce carbon dioxide emissions.

Solar power is a clean, non-polluting energy source, and the use of PV+storage power generation systems can reduce dependence on fossil fuels, reduce air pollution and greenhouse gas emissions, and contribute to environmental protection and sustainable development. PV+storage technology will promote the transformation and upgrading of the energy industry and make an important contribution to global energy security and sustainable development.

2.4 Improve energy utilization efficiency, reduce energy loss, and solve the problem of electricity consumption in off-grid areas.

PV + energy storage can be distributed layout, reducing the construction of long-distance transmission lines and energy loss in the process of power transmission. In remote areas or places without grid coverage, PV+storage system can supply power independently to meet the power needs of local residents and improve the efficiency of energy utilization. The price of PV+storage is gradually becoming reasonable and the cost is decreasing, which makes PV+storage system gradually become an affordable energy choice.

3. Challenges facing PV+energy storage

3.1 High investment and installation and maintenance costs

PV+storage systems have higher installation and maintenance costs, require larger investments, and currently have relatively low penetration in certain regions.

3.2 Energy storage battery safety to be further improved.

Energy storage technology currently still has certain limitations in terms of safety, energy density, and cycle life, which require further technological innovation and improvement. The efficiency and performance of PV+storage systems also need to be further improved to enhance the overall energy utilization.

Photovoltaic + energy storage technology is gradually becoming a major trend in the energy field with its stability, reliability and environmental friendliness. With the continuous innovation and maturity of the technology, PV+storage system will be applied in a wider range, providing strong support for the sustainable development of the energy industry.
