About Us - Solar Thermal Collector Manufacturer

Since 1978, SunEarth has designed, engineered and manufactured solar thermal systems that turn the sun’s energy into usable heat.

From residential solar water heating and pool heating to multifamily, hospitality, healthcare, agriculture and industrial hot water applications, we build renewable thermal energy solutions around the way people and buildings actually use hot water.

Our products are manufactured in the United States and supported by a team with decades of specialized solar thermal experience.

Manufactured. Engineered. Supported.

Solar thermal is not one product or one application.

It is the engineering of collectors, storage, controls, piping, heat exchange and system operation around a specific thermal load.

SunEarth manufactures solar thermal collectors, complete solar water heating systems, solar pool heating systems, storage, pump stations, controls, mounting hardware and related components for residential, commercial and industrial applications.

Whether the project is a single-family home, a multifamily development, hotel, hospital, school, military facility, agricultural operation or industrial process, our focus is the same: design a system that delivers dependable thermal energy over the long term.

SunEarth has been manufacturing solar thermal products in the United States since 1978.

Our Fontana, California facility gives us direct involvement in the products we sell; from material selection and fabrication through assembly, testing and shipment.

Domestic manufacturing also keeps product knowledge close to the people designing and supporting SunEarth systems.

No two buildings use hot water exactly the same way.

SunEarth systems are engineered around climate, load, storage, operating temperature and application rather than approached as a one-size-fits-all solution.

We support homeowners, contractors, engineers, architects, developers and facility teams with the products and technical resources needed to design solar thermal systems for real-world conditions

Solar thermal systems are long-term infrastructure.

That means support matters long after the original installation.

SunEarth maintains decades of product and application knowledge and continues to provide technical documentation, replacement components, design resources and experienced support for both new and existing systems.

Solar water heating, solar pool heating and solar-assisted space heating solutions for new and existing homes.

Solar thermal systems designed for buildings with meaningful hot water demand, including multifamily housing, hospitality, healthcare, education, food service and other commercial facilities

Renewable thermal solutions for applications where heat is part of the operation - from agriculture and food processing to large-scale thermal storage and industrial hot water demand.

SunEarth is part of The Solaray Corporation, a 100% employee-owned company.

Employee ownership means the people manufacturing, engineering, shipping, supporting and standing behind our products share directly in the success of the company.

It reinforces something that has always mattered at SunEarth: build products we are proud to put our name on and relationships designed to last.

For our customers, contractors and partners, that means working with people who have a personal stake in doing the job well.

SunEarth was incorporated in California in 1978, making us one of the most established solar thermal manufacturers in the United States.

But longevity alone is not the goal.

Over more than four decades, solar thermal systems, building requirements, controls, storage technologies and energy priorities have continued to evolve - and so have we.

Today, SunEarth combines that depth of field experience with modern controls, system engineering, thermal storage and application-specific solutions for a changing energy landscape.

As buildings electrify and electrical loads increase, efficiently producing thermal energy becomes an increasingly important part of the energy conversation.

Hot water is energy.

Our job is to help produce it intelligently.

Reliable solar thermal performance begins with more than a collector.

SunEarth supports complete system design with collectors, storage, pumping, controls, mounting hardware, heat exchange equipment and the technical resources required to bring those components together.

Our solar thermal products and systems are designed for demanding climates and long-term operation, with certified system options available for residential, commercial and industrial applications.
