Changzhou Longquan Solar Energy Manufacture Co., Ltd

Changzhou Longquan Solar Energy Manufacture Co., Ltd. has been in business since 1991, which is much longer than most new suppliers — giving them experience and stability in a competitive market. Their key products like solar water heaters, vacuum tubes, and heat pipes are common in solar thermal systems, making them a familiar choice for buyers in regions with high heating needs. Being headquartered in China gives them access to large-scale manufacturing and low production costs. However, none of their verification details — phone, work email, or account email — are confirmed, which raises concerns about legitimacy and responsiveness. Buyers should verify these details before placing large orders or sharing sensitive requirements. Without document verification, it's harder to trust the company's operations or compliance with international trade standards. This lack of verification is common among older suppliers who may not have updated their digital presence, so buyers should cross-check with other sources or request additional proof.
