Solar PV Module Buyer's Guide 2023

May 30, 2023

For the 2023 PV Module Buyer’s Guide, we sent a questionnaire to every major solar panel manufacturer. This Guide is a snapshot of their global and U.S. capacity, what’s new this year, and their top product lines. Click products to expand for more information.

The solar module market is more competitive than ever in terms of pricing and power rating. So, what else should residential and commercial solar installers and procurement teams consider when selecting solar modules?

“With the Inflation Reduction Act (IRA) expected to accelerate residential and C&I solar deployment, thanks to more certainty around the long-term extension of the Investment Tax Credit (ITC), demand for high-power and high-efficiency modules with long-term warranties will grow more competitive. Installers must ensure they have access to a dedicated module supply to avoid project delays, procurement problems, and customer dissatisfaction,” – Melissa Cavanagh, Marketing Manager, North America, Trina Solar.

“The variety of solar modules available in the U.S. market, from both established and new players, is growing. Installers know that not all modules are created equal, and selecting a relatively unknown module company comes with risks in terms of warranty, reliability, performance and customer service. Established, bankable brands – whose modules go through rigorous third-party testing by labs like PVEL and RETC – offer peace of mind and a proven track record,” Elena Zhang, General Manager of DG North America for LONGi Solar.

“As the solar industry grows in importance, so does our responsibility to become more sustainable too. Consumers are far more cautious about the environmental footprint of the products they are buying and want to make more responsible choices. Installers must be aware of sustainable aspects of their modules’ portfolio, on top of technical features.” – Cary Hayes, President, REC Americas.

What’s new? Since its founding 25 years ago, accumulative shipments of Trina Solar’s modules totaled 140 GW, while 210mm module shipments exceeded 65GW by Q1 2023, ranking first globally. As the first mover of 210mm modules, Trina recently put 210mm n-type capacity into mass production, reinforcing the company’s competitiveness with next-generation n-type cell technology. Trina’s newly upgraded n-type i-TOPCon modules with Vertex 210R (rectangle cells) n-type 605W and Vertex 210 (square cells) n-type 695W modules, with up to 22.4% efficiency. The company’s newest facility has already begun production of 210mm monocrystalline ingot and will have 20GW of planned capacity once fully operational. Trina’s 6.5GW wafer facility in Vietnam marks the milestone of a completely restructured and independent supply chain.

Perfect for: Rooftops

At 210 x 210 mm, the G12 wafers and cells in the REC Alpha Pure-R are larger, providing higher power output. By arranging the 80 half-cut HJT cells in a gapless design, it is possible to maximize the power-generating area of the module. Advanced cell interconnection technology improves current flow and eliminates invasive soldering processes, contributing to high efficiency and long-term performance. The four-section junction box divides the module into four strings, reducing the size of the sections that shut down when shaded. This allows the module to generate more energy even when partially shaded. The low temperature coefficient also causes the solar module to operate efficiently even on hotter days, generating more energy for homes. With the rapid growth of the solar industry, solar modules and their manufacturing need to become even more sustainable. High efficiency like for the Alpha Pure-R, high durability with guaranteed long-term performance, and no lead save resources and make recycling easier when the solar module reaches the end of life.
