Our Products
Solar Water Heating Systems
SolarTherm solar water heating systems are designed and manufactured to optimise the heat absorption and efficient heat transfer from solar collector to the water running in the copper riser tubes of the panel. Heated water is transferred to the insulated hot water storage tank by thermo syphon effect. The heated water is stored in storage tank which is constructed from 316L Food grade stainless steel to avoid corrosion. This is a continuous cycle taking place as long the sunlight is available. Since 1982, SolarTherm has established themselves as a 100% solar power solutions provider. As the market Leader in the industry, SolarThem lives to the promise of continued quality and reliable service

Domestic Solar Water Heating Systems

Heated water is transferred to the insulated hot water storage tank by thermo syphon effect. The heated water is stored in storage tank for usage. This is a continuous cycle taking place as long a the sunlight is available.

Commercial Solar Water Heating Systems
SolarTherm solar water heating systems are designed and manufactured to optimise the heat absorption and efficient heat transfer from solar collector to the water running in the copper riser tubes of the panel. Heated water is transferred to the insulated hot water storage tank by using forced circulation system. The heated water is stored in centrally located large storage tanks with necessary control systems.
Solar Electricity Systems

Residential Solar Electricity Systems
Domestic solar electricity systems, also known as residential solar PV systems, produce electricity for homes using solar panels. These systems harness sunlight to generate clean energy, reducing homeowners' electricity bills and environmental impact. They typically include solar panels, inverters, and a connection to the household's electrical system, making it possible to power appliances and lights with solar-generated electricity.

Commercial Solar Electricity Systems
Commercial solar electricity systems, also known as commercial solar photovoltaic (PV) systems, generate electricity for businesses and large-scale operations by converting sunlight into electrical power using solar panels. These systems consist of solar panels, inverters, and mounting structures. They help commercial enterprises reduce energy costs, decrease reliance on non-renewable energy sources, and contribute to a greener environment.
