Thank you, Gary, and thank you, everyone, for joining the call. Before we disclose our Q1 results, let me quickly start by addressing the inflation of the commodity input costs, one of the key challenges facing the solar industry these days. The good news is by far the higher input costs have not been an issue for ReneSola Power. Now let's turn our attention to Q1 results. I will summarize our financial performance and review our operating highlights in the quarter. I will then turn our call over to Ke, who will cover financial results in more detail and will provide 2021 guidance. We will then open the call to questions. Revenue was $22.8 million, up 39% sequentially and up 8% year-over-year. Gross margin of nearly 30% was well above expectations. Our operating income on GAAP basis was $4.1 million, up significantly, both sequentially and year-over-year. Adjusted EBITDA increased more than 250% from last quarter. Importantly, we reported our fourth consecutive quarter of profitability. Our development pipeline remains strong, ending the quarter with late-stage projects of over 1.3 gigawatts. We see this momentum continues. The expanded pipeline of business activity indicates greater demand for project development, and we remain optimistic about our multi-year growth prospects. We continue to focus on profitable markets, including the U.S. and Europe, where we see tremendous growth opportunities with high-quality projects. Let me now discuss the recent operational highlights. First, we completed the sale of our 12.3 megawatts portfolio of projects in Hungary to Obton, a leading international solar investment company in Denmark. The portfolio comprises 20 solar farms with a combined capacity of 12.3 megawatts. This 20 solar farms are now in operation and are qualified under the Hungary 25-year CAT feed-in tariff scheme. Second, we successfully closed the sale of about 10-megawatt portfolio of solar projects in Utah to Greenbacker Renewable Energy Company. The portfolio consists of three ground-mounted commercial distributed generation sites located in Utah. The projects are so-called "behind the meter" and will sell electricity directly to two off-take parties. The projects were sold at the "Notice to Proceed" stage, and Greenbacker will complete the construction and retain long-term ownership. Third, we executed the JV agreement with Eiffel Investment Group last month. The collaboration between the two companies aims to accelerate the development and financing of our current and future solar projects across Europe. With the signing of the JV agreements, ReneSola Power and Eiffel Investment Group have created European Solar Energy Development JV. The initial portfolio will consist of 340-megawatt advanced stage development projects located in Poland, Spain, and France, which both partners will support and develop to reach ready-to-build stage. The joint venture company intends to fund the development of up to 700-megawatt of solar projects in the next three years across Europe. Fourth, we strengthened our financial position through debt reduction and capital raise in Q1. As shown in our balance sheet, we reduced short-term borrowings by $31 million in the quarter, a major achievement for us. Additionally, we further shored up the balance sheet, leveraging the capital markets to raise capital. In the fourth quarter, we raised $290 million through our registered direct placement of ADS. As a result, we significantly improved our capital structure and debt-to-assets ratio of 0.19. From a capital allocation standpoint, we intend to use the net proceeds to expand our solar project pipeline, further penetrate the solar-plus-storage market, for working capital, and for potential strategic M&A opportunities. We believe the capital infusion will enable us to execute our long-term strategic growth plan as we further consolidate our transformation into an asset-light solar project developer. Fifth, we remain positive on our storage strategy. Energy storage is a large and growing market. The solar storage assets we acquired from Nova Development Management last year are highly complementary to our existing business. Additionally, the acquisition provides us with access to utility projects and development activities in a number of states across the U.S. Building on the successful acquisition of the energy storage business from Nova, we expect to grow our pipeline in the solar-plus-storage market. We are actively evaluating opportunities in both solar-plus-storage and independent storage facility solutions in the U.S. and UK. We are making good progress, and looking forward to capture more market opportunities. Putting it all together, we are making great progress growing our business and achieving our mission to become a leading global project developer. I will now update you on our project pipeline. At quarter-end, our late-stage pipeline was 1.3 gigawatts, up from 1 gigawatt last quarter. We continue to direct resources to the market with the best profit potential. Our objective is to add incremental project pipeline in our core markets to reach 2 gigawatts by the end of 2021. We also intend to monetize approximately 300 megawatt this year. Let's review highlights from certain key geographies. First, let's turn our attention to the U.S. shown on Slide 7. Our late-stage project stand at 340 megawatts, of which 82 megawatts are community solar in Maine, Minnesota and New York. Additionally, we have projects under development with a mix of corporate, municipal and utility off-takers in other states, such as California, Pennsylvania, Florida and Illinois. Meanwhile, we operate 24 megawatts of small-scale utility projects in North Carolina. In Poland, shown on Slide 8, our key asset is a portfolio of project rights. We have a pipeline of 271 megawatts of ground-mounted projects under development and construction. Slide 9 refers to Hungary, where we also invest in small-scale DG projects. Our pipeline has the combined capacity of 42 megawatts in the country. Those projects are all under development. Slide 10 and 11 detail our pipeline in France and Spain. We have 100 megawatt in France and expanded our pipeline to 180 megawatts in Spain, all of which are ground-mounted and under development. We are also getting traction in Germany, as shown on Slide 12. We have a project portfolio of probably 50 megawatts, all of which are ground-mounted projects under development. In the UK, shown on Slide 13, we have a project pipeline of nearly 210 megawatts, including ground-mounted projects and solar-plus-storage. All of those projects are under development. In addition to our development pipeline, we operate a portfolio of 173 megawatts of solar projects that generate high margin recurring revenue. As you'll see on Slide 15, our operating assets, including 148 megawatts of commercial rooftops in China and 24 megawatt of utility solar in the U.S. In China, we are preparing to build at least 100 megawatt of commercial rooftop projects within 2021 and plan to operate them in our light IPP model. In conclusion, we are off to a solid start in 2021. The strong momentum reflects high demand in the markets we serve, the resiliency of our business model and excellent execution by our team. Let me now turn the call over to our CFO, Ke Chen for comments on our financial performance. Ke?
