We are committed to conducting our business with integrity, reducing the environmental impact of our products and operations, supporting our communities, striving for improved conditions in our supply chain and creating an inclusive, safe and healthy workplace. From helping over 2 million global installations lower their environment carbon footprint, to accomplishing it ourselves at home; Morningstar’s employees & facilities live and breathe clean, renewable energy! Here are just a few examples of our commitment:

Facilities & Operations:

Using our own TriStar™ MPPT Charge Controllers we are running a 4.2kW Grid-tied with Battery Back-up solar-electric power system at our Newtown, PA (USA) office and a 30kW Grid-tie system at our Jessup, Maryland (USA) office.


Creating an inclusive, safe & healthy workplace; our manufacturing facilities are CNS 15506, ROHS & REACH compliant; furthermore, they classified as Class I sites and are certified to the international management standards ISO 14001 & OHSAS 18001.

Packaging Innovation:

Reducing the weight and volume of our product packaging, improving recyclability and expanding our use of recycled materials.

Supply Chain:

Supporting high labor and environmental standards in our supply chain—strengthening the work product of both Morningstar and the suppliers we work with. These efforts are essential to maintaining the quality of our products and the success of our business.

Community Support:

From supporting education, to volunteerism, to environmental protection, to helping non-profit aid organizations bring clean, dependable solar-electric power to the developing world; Morningstar is happy to be helping the communities where we work, live and operate.
Our sustainability goals are simple and have been at our core since we started operations in 1993. We strive to always maintain our focus on environmental excellence and to help build a more sustainable world. We endeavor to positively influence the impact on our climate and to save our planet’s natural resources by lowering carbon dioxide (& other greenhouse gasses) and reducing waste. The success of our environmental stewardship efforts is echoed & supported by the commitment and enthusiasm of our employees. Together we are protecting the environment & supporting the communities where we work, live and operate.
