Corporate Social Responsibility Report
Chairman’s Statement
In 2020, in response to global challenges such as COVID-19 pandemic, 
climate change and resource depletion, it has become a broad 
consensus of the international community to promote a higher-quality 
"green recovery" of the world economy and promote global sustainable 
development. We need to accelerate the transition towards new energy, 
improve energy conversion efficiency with greater determination and 
courage, so as to deal with climate change more professionally. 
Sungrow always takes “Clean power for all” as the mission of our 
business, and is constantly committed to the research, development, 
promotion and application of clean energy conversion technologies. As 
a responsible corporate citizen, we added a new topic on climate change 
in this year’s report and disclosed the company's action plan to deal with 
climate change. We have joined RE100. By constructing our own new 
energy power plants, installing rooftop photovoltaic system in factories 
and engaging in green card transactions, we tried to increase the 
proportion of green energy use at an annual rate of 10% with the hope of 
covering the use of green electricity in production and operation by 2028. 
With the introduction of ISO14064 and 14067 standards, we have taken 
several measures to quantize the carbon emissions such as carrying out 
carbon inventory and carbon footprint accounting. We have gradually 
established a scientific system for carbon emission management, and 
promoted the implementation of various emission and carbon reduction 
measures.
In the past year, Sungrow has strengthened ESG management, 
continued to improve the corporate governance system. Its increasing 
revenue has brought more returns for shareholders. We continuously 
optimized the quality management system, promoted product and 
technology innovation, and responded quickly to meet customers’ 
service demands. We increased investment in safety production to 
protect employees' occupational health and safety, accelerated the 
training of international talents, and promoted employees' dual-channel 
career development. We actively assumed the primary responsibilities of 
fighting against epidemic and promoting production resumption, aided in 
the construction of Wuhan Leishenshan Hospital, helped partners 
achieve work and production resumption, strived to ensure the supply 
and service for global customers, and achieved a win-win result with all 
parties in the value chain. We continued to promote public welfare 
programs on education, support scientific research of related specialties 
in colleges and universities, carry out voluntary activities such as energy 
education, and strived to make more contributions to community 
development.
For a long time, Sungrow has been exploring the business model of 
green development, hoping to create more value for shareholders, 
customers, suppliers, employees and the community by giving full play 
to its business strengths and advantages. In the future, Sungrow will 
further accelerate the scientific and technological innovation and 
development and application of the new energy industry, work with more 
industrial chain and supply chain partners to speed up the global 
decarbonization process, and actively meet the expectations of 
stakeholders, provide more innovation and professional solutions, so as 
to promote the green transformation of global economic and social 
development and people’s lifestyle, and build a more sustainable future.

——Response to Global Climate Change
Climate change is a key issue in our times. The United Nations Intergovernmental Panel on 
Climate Change released its fifth assessment report in 2013, which made it clear that climate 
change really exists and that human activities are the main cause of it. The goal of temperature 
control of 2 ℃ put forward on the Paris Agreement in 2015 makes carbon reduction a clear policy 
anticipation, which has a direct or indirect impact on all walks of life. At the same time, people from 
all over the world pay unprecedented attention to climate change, making it a public expectation 
for enterprises to cope with climate change.
At present, the global climate conditions are becoming more and more grim with COVID-19 
pandemic, which have a profound impact on the sustainable development of economy and 
society. We are standing at a turning point. The goal of global carbon neutrality injects new vitality 
into the global green recovery after the pandemic, and promotes the realization of the 
temperature control goal of the Paris Agreement and global climate governance.
While governments adopt firm policies to support rational climate change, clean energy 
enterprises are facing development opportunities brought by climate change actions. In addition, 
how enterprises further reduce non-fossil energy costs, make energy more stable, more friendly 
and more accessible to people and make contributions to coal neutrality with their professional 
technologies and products have become major issues for the development of enterprises. As a 
global enterprise, Sungrow，who adheres to the social responsibility concept of "Green Missions, 
Better Future", shows its responsibilities to stakeholders and the entire global environment and 
takes decisive and strong actions to tackle climate change. Sungrow has reaches a green and 
low-carbon consensus, further reduces resource consumption and carbon emissions, and strives 
to make everyone a climate citizen.

Ecological Restoration and Biodiversity Conservation
During the development of photovoltaic and wind power generation projects, Sungrow strictly abides by relevant 
environmental laws and regulations, strives to integrate ecological environment with photovoltaic and wind power 
generation projects, and preserve and improve local fragile ecological environment system through technologies. The 
Company has created a three-dimensional model of land use of “PV power generation on panels + cultivation below 
panels" and a “New energy+” model for land quality improvement and contaminated land use, which benefits local a lot.  
Development site: The Company pays attention to environmental protection and people and nature harmonious 
coexistence, adds ecological sensitive factors into risk investigation in the early stage of the project, including public 
welfare forest, ecological red line, basic farmland, high-standard farmland, wetland, flood detention area, water source 
protection area, and formulates and adjusts construction plans to terrain and environment to ensure the feasibility of the 
project.
Project construction: The Company conducts their work in strict accordance with the design of land acquisition boundary, 
uses temporary barriers and slope protection at the land acquisition boundary externally and adopts covering, solidification 
and greening internally to ensure that civil construction will not cause additional disturbance and damage to the 
surrounding ecological environment. At the same time, the Company established environmental factor control ledgers 
during the whole construction process, strictly following the principle that safety facilities of a construction project must be 
designed, constructed and put into production to carried out green construction and acceptance.
Case:
This 150MW soil remediation and comprehensive utilization photovoltaic power generation demonstration project 
in Renhua County, Guangdong Province is the country’s first contaminated soil restoration and PV utilization 
project. There are two heavy industrial and mining enterprises in this county, where the content of heavy metals 
in soil was extremely high, leading to Renhua Blood Lead Event. Based on the local situation, Sungrow 
customized an integral solution that combines PV power generation on panels with soil restoration below panels 
for Renhua County. The Company conducted research and demonstration in joint force with several top soil 
research institutes in the country, and decided to plant shade-loving hyper-accumulators to reduce heavy metal 
contamination in soil through the accumulation and extraction effects of plants, and gradually restore 
contaminated land to cultivable land. This project provides a new approach to ecological restoration and 
comprehensive governance that can be reproduced and popularized across the country. The project generates 
more than 150 million kWh of green power every year and saves 1.5 million tons of standard coal.

environmental facilities, such as project application and approval, environmental impact assessment and approval, and 
environmental protection acceptance upon completion, must be completed in accordance with national laws and 
regulations. For commissioned projects, environmental monitoring and maintenance of environmental protection 
facilities must be performed regularly to ensure the effectiveness of environmental protection measures. For suspended 
projects, registration for suspension should be made according to the provisions, and relevant paper work should be 
completed when projects are restarted. Upon completion of a project, auxiliary facilities should be dismantled and the 
site should be restored, in order to minimize impact on environment.
The Company organizes various departments to identify and assess environmental risks every year. If key elements or 
regions of business activities have changed, specific analysis will be made to ensure the accuracy and effectiveness of 
risk identification. If environmental risk identification is found to be insufficient or missing during internal and/or external 
audits, the environmental risk identification methods should be adjusted and optimized immediately, and a new round of 
environmental risk identification and assessment should be made. According to the results of environmental risk 
assessment, different countermeasures should be taken, and environmental incident prevention and contingency plans 
should be implemented in procurement, logistics, production and sales.

Corporate Social Responsibility Report
Develop and construct PV poverty alleviation power plants according to local conditions. The Company has customized 
power plant construction plans for residential poverty alleviation, village poverty alleviation and centralized poverty 
alleviation in different regions of the country. Meanwhile, the Company has carried out trials of “centralized construction 
and continuous development” in many areas, which applied unified planning, unified site survey, unified design and 
development, and unified application for grid connection to poverty alleviation power plant projects, maximized resource 
allocation and utilization.
Promote the localization of labor employment and increase income for local personnel. In the process of carrying out 
targeted poverty alleviation projects, the Company not only sent power generation devices to poverty-stricken 
households, but promoted the localization of labor employment in the construction of power plants. After the power 
plants were completed and put into operation, the Company provided operation and maintenance staff with localization 
training. The localization ratio of labor employment and training both exceeded 80%. In this way, poverty-stricken people 
could truly feel that industrial poverty alleviation expanded income sources and increased employment.
Pay attention to the full life-cycle management of projects. During the construction of the power plants, the Company 
strictly controlled the quality of equipment, carefully controlled the process in the installation, project commissioning and 
acceptance,  so as to strengthen the management and control of full life-cycle of PV poverty alleviation projects from the 
source and ensure the best quality and highest efficiency of project implementation, thus creating poverty alleviation 
demonstration and excellent projects that truly reassure the government and satisfy the masses. To tackle the practical 
problems such as monitoring and management, cost settlement and low operation and maintenance efficiency after the 
completion and operation of PV poverty alleviation projects, the Company has specially developed an intelligent platform 
for PV poverty alleviation management to improve the unified information management of power plants projects, realize 
the unified and centralized management of users, and the unified and classified management of information resources 
of PV poverty alleviation projects. Through real-time data and information sharing, failure warning of power plant 
equipment and big data analysis, the Company reduced power generation loss, reduce humans costs of operation and 
maintenance, give early warning in time, and avoid potential safety hazards.
Attach great importance to environmental protection and consciously safeguard the interests of all parties. During the 
implementation of poverty alleviation power plant projects, the Company required the project personnel to always take 
into account the local natural and cultural environment. In addition, the Company has pioneered in adopting the 
"six-party confirmation " including forestry/water conservancy, land, environmental protection, power grids, owners, 
village committees, which ensures that all work meets the requirements and conforms to the rights of stakeholders. This 
measure has been gradually recognized by local poverty alleviation authorities and relevant parties since the poverty 
alleviation project was first launched in Yuexi County, Anhui Province in 2015.
Sungrow will continually give full play to our technical advantages, actively engage in operation, maintenance and 
supervision of related PV power plants in the "post-poverty alleviation era", empower poverty alleviation efforts with PV 
digital intelligence technology, constantly improve intelligent operation and maintenance service network, and expand 
the scope and depth of services, so as to ensure the safe, efficient and reliable operation of poverty alleviation power 
plants, help poverty-stricken families gain continuous and stable power generation income, and contribute to the 
long-term efficacy of the national poverty alleviation undertakings.
