Introduction to commercial and industrial photovoltaic power generation program, and how to save energy and reduce costs?

​

With the rise of global electricity energy costs and the tightening of carbon emission policies, more and more enterprises are focusing on the use of commercial and industrial solar photovoltaic (PV) power generation in order to reduce electricity costs, enhance electric energy dependence, and practice green and low-carbon development strategies. This paper will introduce in detail the commercial and industrial solar photovoltaic power generation program recommendations, and analyze how to achieve the goal of energy saving and cost reduction through rational planning and technology optimization.

I. Advantages of commercial and industrial photovoltaic power generation

1. Reduce electricity costs

The cost of electricity often accounts for a large proportion of the cost of production and operation of enterprises, and the use of solar photovoltaic power generation can effectively reduce the enterprise's dependence on utility power, realize “self-generated, self-consumption, surplus power on the Internet”, to reduce the economic burden brought about by the peak price of electricity.

2. Improve energy independence

Enterprises in some regions face unstable power supply and power limitation problems, such as India and Africa, where power consumption is very tense. Commercial and industrial photovoltaic systems can provide a stable energy supply, especially when equipped with energy storage systems, can continue to supply power at night or grid failure.

3. Flexible mode of electricity consumption

Combined with the PV energy storage system, it can realize “peak shaving and valley filling”, and reduce the cost of purchasing electricity from the grid during peak hours.

4. Enjoy policy subsidies and carbon trading benefits

Some regional governments have launched different PV incentive policies, such as electricity subsidies, tax incentives, carbon trading market revenue. Enterprises can enjoy policy dividends through PV power generation and further reduce investment costs.

5. Enhancing corporate image and practicing ESG development

Installing PV systems not only helps enterprises fulfill their social responsibility (CSR), but also improves brand influence and enhances supply chain competitiveness, especially for environmentally conscious international enterprises, which is conducive to compliance with ESG (Environmental, Social and Corporate Governance) standards.

Ⅱ.Introduction of commercial and industrial photovoltaic power generation programs

1. Rooftop Distributed PV Program (applicable to factories, shopping malls, logistics parks, etc.)

Program features:

Make full use of rooftop resources

Convert the roofs of enterprise plants, warehouses and shopping malls into PV power stations, realizing self-generation and self-consumption, with surplus power going online.

Suitable for long-term operation enterprises

The investment return cycle is generally 5-7 years, and the system life can be more than 25 years, with long-term stable income.

Technical Solution

Adopt high-efficiency monocrystalline silicon module + intelligent inverter to optimize power generation efficiency.

Applicable Scenario:

Applicable to manufacturing, warehousing and logistics with high power consumption and large roof area; as well as large shopping malls and shopping centers with a high match between daytime power peaks and PV power generation, and educational institutions and hospitals that wish to reduce the cost of utility power consumption.

Revenue model:

Self-generation and self-consumption can be used to prioritize power supply to enterprises and reduce the cost of purchasing power from the grid.

Utilize surplus power to go online and sell power to the national grid or local grid for additional revenue.

Using the peak and valley tariff optimization scheme, combined with the energy storage system, to store power at low valley tariffs and use it at peak times.

2. BIPV Building Photovoltaic Integration Program (for new factories, commercial complexes)

Program features:

Combine PV modules with building materials, such as PV curtain wall, PV tiles, etc., to realize the integration of building power generation, the BIVP program. It can also reduce building energy consumption. PV curtain walls and PV roofs can play a role in heat insulation and cooling, reduce air conditioning loads, further reduce energy costs, and can achieve both aesthetics and functionality, which is applicable to green buildings, low-carbon parks and other high-standard building projects.

Applicable Scenario:

Applicable to high-end commercial complexes, office buildings, to achieve the effect of both aesthetics and energy saving. It can be used to build green intelligent parks, such as industrial parks, science and technology parks, as well as related government agencies and public buildings.

Revenue model:

Combined with architectural planning, it realizes long term low carbon income. Grid-connected photovoltaic power station to obtain power generation revenue.

3. Energy storage + PV smart microgrid program (this program is applicable to areas with limited electricity and peak electricity prices)

Program features:

Photovoltaic + energy storage system, storing excess electricity during the day and releasing it at night or during peak electricity consumption.

Enhance energy independence and avoid the impact of grid power limitation on enterprise production.

Intelligent scheduling system to optimize power consumption strategy and improve economic efficiency.

Applicable scenarios:

Data centers and communication base stations with high requirements for power supply stability. Limited power, industrial enterprises that need to reduce peak electricity costs, as well as large power consumption, peak power consumption is obvious large-scale supermarkets, hotels, etc..

Revenue model:

Peak period with energy storage electricity, charging in the low valley, reduce peak electricity costs.

Ⅲ.How to realize energy saving and cost reduction?

1. Translated with www.DeepL.com/Translator (free version)

Optional self-investment and self-build mode, where the enterprise invests independently and enjoys long-term income, applicable to enterprises with sufficient capital.

Third-party investment (EPC+PPA): invested and constructed by professional PV companies, enterprises buy electricity according to the contract, no initial investment required.

2. Improve PV system efficiency

Prioritize the use of high-efficiency PV modules, selecting high-performance monocrystalline silicon modules with a conversion efficiency of more than 22% can improve power generation capacity.

For smart inverters, AI optimization algorithms need to be used to regulate power and improve the match between power generation and power consumption.

And regular maintenance and cleaning, such as dust, bird droppings, etc. may reduce the efficiency of the module, regular cleaning can improve power generation by 5%-10%.

3. Optimize power consumption strategy

Reasonable scheduling of electricity load, you can adjust the operating time of high energy consumption equipment to the peak period of PV power generation, reducing the dependence on the power grid.

And combined with the energy storage system, through the tariff arbitrage to reduce the cost of electricity, optimize the structure of electricity use.

4. Fully utilize government policies

In areas with policy subsidies, PV subsidies and tariff subsidies can be applied to reduce initial investment costs.

As well as participate in the carbon trading market, sell carbon emission reduction (CCER), get additional income.

5. Risk Control Suggestions

Regarding the warranty of PV equipment, you need to choose a first-tier brand with 25-year warranty for modules and 10-year warranty for inverters to reduce the risk of failure.

IV. Summary

Commercial and industrial photovoltaic power generation can not only effectively reduce corporate electricity costs, but also enhance energy independence, is the enterprise to deal with rising electricity prices “buffer”, but also to realize the “gas pedal” of the low-carbon transformation, help green sustainable development. Whether it is rooftop distributed photovoltaic, BIPV building photovoltaic integration, or energy storage + photovoltaic microgrid mode, the optimal solution can be customized according to the needs of enterprises to achieve the goal of energy saving and cost reduction. Through scientific site selection, high-efficiency equipment combination and intelligent operation, enterprises can significantly reduce the cost of energy consumption, and at the same time gain both policy dividends and market competitiveness. It is recommended to give priority to photovoltaic system integrators with rich project experience to ensure that the whole life cycle benefits are maximized.
