For detailed reasons of performance decline and the Company's countermeasures for improving profitability,
please refer to “Overview” of IV. Core Business Analysis and “(2) Operating Plan” of XI. Prospects of the
Company’s Future Development in Section III Management’s Discussion and Analysis. Contents in this report concerning future plans, performance forecasts, and etc., do not constitute any
commitment made by the Company to any investor or related party. Investors and related parties should
maintain adequate risk awareness and understand the possible difference between plans, forecasts, and
commitments.
(1) Policy-related risks
Although technologies related to renewable energy power generation are still evolving and grid parity has
been achieved in most regions around the world, there are still a few regions where the power generation cost
or the on-grid electricity price is higher than that of fossil energy, and the unit electricity cost per
kilowatt-hour from wind-solar storage applications maintains relatively high. In addition, considering the
various constraints including grid consumption, intermittent fluctuations in new energy availability, as well
as land and taxation, policy support and encouragement from governments are still necessary. Since the
supportive policies are formulated by the governments of various countries, while the global trend of energy
conservation and emission reduction remains unchanged, major changes in the macro economies of major
markets or relevant supportive policies will affect the growth pace of the industry and the Company’s
profitability to a certain extent. To this end, on the basis of maintaining the leading position in the domestic
market, the Company makes market explorations overseas, and strives to achieve a global footprint to
minimize the impact of policy fluctuations within a single country. Apart from the PV inverter business and
the PV power station investment and development business, the Company makes active attempts in other
business growth points, such as energy storage converters, electric vehicle motor controllers and other new
energy oriented applications based on power electronics technologies, as well as in new business sections
such as energy storage system integration and wind farm development, to dilute the impact of single-industry
(such as PV) policies.
(2) Risk of gross margin reduction due to intensified competition 2021 Annual Report (Concise Version in English)
obvious market advantage. However, the huge potential of domestic and foreign markets has also attracted
fierce market competition. If the Company fails to maintain the leading edge in technological innovation,
new product development, and cost control, the products will face the risk of gross margin declination. As
such, the Company needs to further accelerate new product upgrade and product differentiation through
R&D innovation and increasing R&D investment, so as to provide customers with value-added services,
constantly introduce new products that create greater values for customers, and consolidate product
advantages in the market.
(3) Risk of collecting accounts receivables
As the domestic market grows rapidly, the Company puts more focus on product sales. In consideration of
the PV industry characteristics in China, such as subsidy arrearage, large project amount, and long payment
term, the Company's business growth at fast pace will lead to a quick increase of receivables and certain risks
in payment collection. In order to prevent credit risks and accelerate capital turnover, the Company
formulated strict credit management systems and sale-on-credit policies, and actively reduced the risk of
non-performing loans and bad accounts through legal actions. (4) Risk of international trade frictions and the epidemic impact Under the negative impact of intensified international trade frictions and the continuation of the COVID-19
epidemic, the global economy is under huge pressure of inclination, and governments are launching monetary policies and other economic stimulation policies. While boosting the economy, such policies may
cause supply chain fluctuation, logistic efficiency reduction, and cost increase. The PV industry where the
Company is in also faces short-term pressures due to changes in demand tempo. The Company has formulated a series of defensive measures and lean production plans to actively respond to the global
epidemic and expand the global market on the premise of ensuring the safety and health of employees. By
strengthening the global supply chain layout, improving supply chain management capabilities, the Company
makes every effort to reduce trade frictions and the epidemic impact, ensuring that the annual tasks are
completed on time.
(5) Risk of exchange rate fluctuation
USD, AUD and EUR are the three major currencies used for the Company's overseas revenue settlement.
The impact of exchange rate fluctuations is mainly reflected in the following two areas: a. Because of the
RMB exchange rate fluctuation, changes in operating income measured in local currency pose a direct
impact on the gross margin of main products; b. From the moment sales revenue is confirmed and accounts
receivable is generated to the moment of collecting foreign currency, the Company is subject to exchange
gains/losses from the fluctuations in the RMB exchange rate, which also directly affects the Company's
performance. On the foundation of normal operation and relying on specific businesses, the Company takes
various means, including hedging, continuous monitoring, and timely settling foreign currency sales to
reduce exchange-related loss and control operating risks.
(6) Risks in the supply chain of semiconductor components
Semiconductors used in the Company's power electronic devices mainly include power semiconductors and
chips that are mostly sourced from overseas since there are limited local supply and the performance of local
components are yet to be improved. With the rapid growth of new energy vehicles, renewable energy power
generation, 5G use cases, and charging infrastructure, plus the epidemic impact on the production capacity of
the above-mentioned manufacturers, semiconductors are facing certain risks of short supply and price
2021 Annual Report (Concise Version in English)
partnerships with suppliers, and locked orders in advance, so as to get hold of the industry supply dynamics
and secure the supply chain to the maximum extent.
(7) Risks in construction management of PV power station investment and development projects PV power station projects feature large amount of investment and short lead time. These projects not only
involve ground resources but also commercial roofs. For these projects, the investment decision-making is
quite challenging, and a lot of uncertainties exist in project engineering and implementation, which may lead
to project delays and jeopardize timely grid connection for power generation. While challenging the
Company's project management, the projects also require a huge amount of working capital. In response to
such risks, the Company makes cautious considerations when selecting new energy power generation projects to prioritize those with better grid connection conditions, clearly communicated subsidy policies,
controllable installed cost and higher gross profit. Meanwhile, the Company further enhances engineering
management and improves project management level. After entering into sales contracts with customers, the
Company reinforces project construction management in a timely manner, adequately communicates with
customers on the progress, and adjusts the work schedule according to the result of communication, so that
the impact of project delay on the Company's production and operation is eliminated or alleviated to the most
extent. By providing project owners with safe, efficient and intelligent PV power stations that meet their
needs, the Company's reputation in PV power station investment and development is improved. (8) Risk of module price increase
Module price increase may lead to a certain degree of delay in the installation of PV power stations the
Company invested and developed, thereby affecting the revenue and gross profit of the Company’s power
station investment and development business. In view of the overall supply and demand of the industry, as
the upstream production capacity is gradually released, the supply shortage will be further alleviated, the
module price will gradually fall back to a reasonable level, and the increase in global installed capacity will
be resumed.
The board meeting has deliberated and approved the following profit distribution proposal: Based on a base
quantity of 1,485,215,984 shares, a cash dividend of RMB 1.10 per 10 shares (tax inclusive) will be
distributed to all shareholders, no bonus share (tax inclusive) will be distributed, and no share distribution
from capital reserve.

Section III Management’s Discussion and Analysis
I. Discussion and analysis of business situation
In the reporting period, due to unbalanced supply and demand in the upstream and downstream of the industrial chain, the long
lead-time of upstream capacity expansion, and the high installed capacity expected in the PV industry, the price of silicon materials
rose sharply, causing different price increases across the entire PV industry chain, including silicon wafers, cells, and modules.
According to data from the China Photovoltaic Industry Association, China's initial investment cost of PV systems in 2021 increased
by 4% year-on-year, marked the first increase in many years. Due to the price increase, installation schedules were postponed. The
National Energy Administration’s data shows that, in 2021, China’s newly installed PV capacity was 54.88 GW, a year-on-year
increase of 13.9%. According to the data of the International Renewable Energy Agency (IRENA), the global PV installed capacity
in 2021 was 133 GW, a very small year-on-year increase of 5.5% only. In the context of global warming, green and low carbon has become a global consensus. Governments around the world have actively
released policies to promote the development and utilization of renewable energy. More than 170 countries around the world have
put forth Zero Carbon or Carbon Neutrality targets, and the development of renewable energy such as PV and wind power has been
globally acknowledged. In 2022, as the silicon material production capacity is gradually released, the supply shortage will be
alleviated, the market price of silicon material is expected to drop, and PV power generation will become the most competitive power
supply in more and more countries. Driven by the carbon neutrality goals, the clean energy transformation and green resurrection
across many countries, a rapid growth is expected in the average annual installed capacity of global PV during China’s 14th
Five-Year Plan period.
