Solar water heating (SWH) systems have been available commercially in the United States since 1891. Solar water heating systems are popular and highly effective in Maine where electricity, oil, or propane are used for water heating. These systems also provide an effective supplement for wood and pellet boilers by minimizing the need to burn fuel during the non-heating season in Maine.
Solar water heating systems are cost-effective solutions for Maine homes and businesses with moderate to high water heating loads. In residential heating applications, these systems are designed to offset 60-70% of the energy required for annual water heating. With an auxiliary source of heat, such as oil, propane, or electricity, owners always have the comfort of hot water without the typical energy costs.
High commercial hot water consumers such as hotels, car washes, laundromats, breweries, and dairy farms across Maine can also benefit significantly from this technology. By utilizing our solar design expertise and attention to detail, Maine companies can distinguish themselves by making a solid long-term investment that demonstrates their leadership and commitment to value with a solar water heating system.



The proper integration of solar water heating with auxiliary heating sources such as electricity, oil, propane, and wood ensures an ample supply of hot water regardless of demand and available sun. Because Maine homes and businesses use a wide variety of appliances for water heating, each project requires careful consideration.
