High-Performance Solar Hot Water Collectors
SunEarth manufactures high-performance solar hot water collectors engineered for residential, commercial, and industrial solar thermal systems worldwide. For almost five decades, SunEarth collectors have powered renewable hot water solutions across a wide range of climates and applications, from multifamily housing and hospitality properties to military installations, agriculture, and industrial process heating.
SunEarth solar thermal technology is deployed throughout the United States, Puerto Rico, Guam, Mexico, Canada, and international markets including the Middle East, where large-scale solar hot water systems support energy independence, operational cost stability, and long-term building decarbonization.
As organizations increasingly pursue Scope 1 emissions reductions, solar thermal water heating has emerged as one of the most effective and immediately deployable strategies for reducing fossil fuel consumption in buildings. SunEarth collectors deliver reliable renewable heat that directly offsets natural gas, propane, and electric water heating demand across both residential and commercial facilities.
Manufactured in the United States and engineered for long-term durability, SunEarth collector systems align with Build America, Buy America (BABA) procurement requirements and support compliance pathways for projects navigating Foreign Entity of Concern (FEOC) supply chain considerations.
Designed for durability, performance, and seamless system integration, SunEarth collectors are trusted by engineers, architects, developers, and installers who require proven solar thermal solutions that meet demanding building codes and project specifications. SunEarth flat plate collectors are SRCC certified and engineered to integrate efficiently into commercial and residential solar hot water systems delivering dependable performance for decades.
Solar hot water collectors, also known as solar thermal collectors, capture energy from the sun and transfer that heat into a working fluid to produce domestic hot water for homes, businesses, and industrial facilities.
For project design teams, SunEarth also provides Building Information Modeling (BIM) objects and digital engineering resources, enabling architects and mechanical engineers to integrate solar thermal systems directly into building designs and energy models.
How Solar Hot Water Collectors Work
Solar hot water collectors capture energy from sunlight and convert it into usable heat for water heating systems. This technology, often referred to as solar thermal, provides renewable heat for residential, commercial, and industrial buildings.
A typical flat plate solar collector consists of several key components designed to maximize heat capture while minimizing energy loss.
Absorber Plate
The absorber plate captures solar radiation and converts it into heat. SunEarth absorber surfaces are engineered to maximize solar energy absorption while maintaining long-term durability in outdoor environments.
Transparent Glazing
A durable glass glazing layer allows sunlight to enter the collector while reducing heat loss through convection.
Insulated Collector Housing
High-performance insulation surrounding the collector housing helps retain heat within the system, improving overall efficiency.
Heat Transfer Fluid
A heat transfer fluid circulates through internal piping inside the collector. As sunlight heats the absorber plate, the fluid absorbs that heat and carries it to a heat exchanger or storage tank where the energy is transferred into usable hot water.
This process allows solar water heating systems to deliver reliable renewable heat throughout the day while significantly reducing conventional energy demand.
SunEarth's Available Collectors:
SunEarth Flat Plate Solar Collector Series
SunEarth manufactures high-performance flat plate solar collectors engineered for long service life, efficient solar heat capture, and reliable system integration across a wide range of climates and installation environments.
All SunEarth collectors can be used in both residential and commercial solar thermal systems. Selection between collector models is typically driven by factors such as system design requirements, desired efficiency characteristics, installation constraints, and regional climate conditions.
From single-family homes to large commercial installations, SunEarth collectors are designed to operate effectively as part of scalable solar hot water systems.
SunEarth Empire Series collectors are engineered to deliver dependable solar thermal performance across a wide range of solar hot water system designs.
Empire collectors feature durable construction and high-performance absorber technology that efficiently captures solar energy and transfers that heat into circulating system fluid.
These collectors are widely used in solar hot water systems where balanced performance, reliability, and installation flexibility are important design considerations.
Empire collectors are commonly installed in:
• residential solar water heating systems
• multifamily buildings
• commercial domestic hot water systems
The Thermoray Series collectors are engineered for reliable performance in areas of the country where system overheating can be an issue. The ThermoRay series is the industry performance leader maximizing the amount of solar energy collected while maintaining the robust characteristics of a SunEarth liquid flat plate solar hot water collector.
SunEarth Oasis Series collectors are engineered specifically for solar pool heating applications, providing efficient solar heat transfer for swimming pools.
The Oasis collector features an all-copper absorber and copper tubing, allowing solar energy to be efficiently captured and transferred directly into circulating pool water.
Copper construction provides superior thermal conductivity and long-term durability compared with many alternative materials used in solar pool heating collectors.
By harnessing solar energy to heat pool water, Oasis collectors help extend swimming seasons while reducing the energy consumption associated with conventional pool heating systems.
Why Engineers Specify SunEarth Solar Collectors
SunEarth collectors are engineered to meet the performance, reliability, and compliance requirements demanded by modern building design and infrastructure projects.
Engineers, mechanical contractors, and developers choose SunEarth collectors for several key reasons:
Proven Solar Thermal Performance
SunEarth flat plate collectors are designed to capture solar radiation efficiently and transfer that heat into circulating fluid for use in domestic hot water systems, space heating support, and industrial hot water applications.
With decades of operational history across thousands of installations, SunEarth collectors deliver reliable performance in diverse climates ranging from tropical island environments to northern continental conditions.

Frequently Asked Questions
Flat-plate solar collectors are composed of metal boxes with transparent glazing , and an absorber plate. The sides and bottom of the collector are covered with insulation to minimize heat losses to other parts of the collector.
SunEarth manufactures flat-plate solar collectors for residential, commercial, and industrial use.
As flat-plate solar collectors are exposed to the sun, the plate heats up, transferring the heat. SunEarth ties everything into the plumbing system of your house.
When it comes to solar collectors and solar panels, terminology refers to the technology involved. The term solar collector is primarily used for solar hot water/solar thermal technology. The term solar panel is primarily used for photovoltaic/pv technology. However, collector and panel can be interchanged by those within the industry.
There are Active Systems and there are Passive Systems. In an active system, a heat pump sends water to the collector to be heated and then flows back to a storage tank for use. In a passive system, there are no moving components. The collector gets filled with pressure and heats water as it sits on the roof, and then the water travels to your heater.
