Riada has supplied solar thermal systems to several projects such as airports, schools, low income housing, and seniors housing. Using the sun to heat water directly instead of generating electricity to heat water is much more efficient. These systems make sense for projects with a high domestic water demand that are looking to minimize reliance on fossil fuels or grid power. With solar thermal systems we need to ensure all components are sized & controlled correctly with proper domestic water storage and heat dissipation strategies in place. Riada can help select all components in the system to offer the best solar fraction without oversizing. Systems can include a dedicated solar controller with start up & commissioning by Riada to ensure proper long term operation of the system.
Riada represents 3 leading brands of solar thermal equipment: DualSun, Naked Energy, and SunEarth. Scroll down to learn more about each brand!
Featured Products
DualSun combines photovoltaic and solar thermal technology info one hybrid solar panel. The cooling effect of the solar thermal water increases efficiency of PV electricity generation, and the otherwise wasted heat from PV panel electricity generation can be utilized for domestic hot water preheating, pool heating, or as a source for heat pump water heating. Made in France, DualSun panels offer a 25-year performance warranty for photovoltaic efficiency, and a 10-year parts warranty on hybrid panels. PV-only panels are available which match the look of the hybrid panels in case a higher ratio of photovoltaic panels is required. All DualSun panels are Solar Keymark and IEC certified.

Naked Energy is a UK company that has revolutionized solar thermal with the world’s highest energy density solar technology. Virtu is a direct-flow evacuated tube solar thermal collector that does not have to be installed at an upright angle to be effective. Tubes lie flat on a rooftop or façade with minimal wind loading, meaning reduced structural mounting requirements. Tubes, frames, and manifolds are supplied by Naked Energy as a cohesive package, with supporting solar thermal system components available from Riada for a complete system approach. Remote monitoring service is available to ensure a successful energy-producing system for the life of the building.
– 20% of the sun’s energy is converted to electricity by a PV cell
– 50% of global energy demand is for heat
– 80% of the sun’s energy can be captured as heat
– 300% more space needed by a PV module to achieve same same carbon savings as Vitru
