Custom solutions for industrial and commercial applications

E3 Energy consistently delivers innovative, technologically advanced, and leading engineering design solutions for industrial and commercial clients.

Engineering design

Our experienced team will identify current system, equipment problems, opportunities and develop, as well as improve current solutions for efficient energy usage and supply. 

Energy efficiency evaluation

Efficient energy usage and production is now more important than ever. Let us analyse your systems and energy usage in order to optimise your current processes to extend savings and minimise losses. 

Energy monitoring

Due to continuous technological developments, energy monitoring is more affordable than ever. However, energy consumption is still often overlooked. Let us help you monitor, analyse and optimise your energy usage.

The need and the value of solar thermal solutions in the industry is continuously growing, as demand for heating accounts for 47% of the world energy demand. South Africa estimates suggest that between 40 and 50% of all final energy needs is for heat. The demand for heat by industry alone accounts for almost 30% of the total energy demand in the country.

Within industry, 66% of energy use is for process heating. If your need is for electricity - generate electricity, if your need is for heat - generate heat, please get in touch with us and we will advise you how.

Examples of successful large scale solar thermal applications for industrial processes

Cape Brewing Company (CBC)

In South Africa, Western Cape-based brewery, the Cape Brewing Company (CBC), has invested in solar power technology to power its production line. They have partnered with renewable energy firm E3 Energy, to produce South Africa’s first commercially available “green beer” which uses solar heated water in the brewing process. 

Klein Karoo tannery - Klein Karoo International (KKI)

E3 Energy has installed a 600 sq.m. solar collector system at the Klein Karoo International tannery to reduce costs and increase competitiveness, since fuel costs are highly volatile. 

The KKI tannery produces ostrich leather products and has a heated water - intensive operation.



Solar thermal energy systems have emerged over the recent decades for numerous applications in domestic and industrial activities like hot water supply, space heating, desalination, drying, refrigeration, distillation, washing, etc., that can conveniently be carried out within the temperature ranges of 60 to 280 °C.

E3 Energy, since 2008, has developed a trustworthy relationship with the leading manufacturers of the solar thermal energy systems worldwide. Continuous process of product development and technology advancements, requires the supplier to be active and involved, to learn implement newest technologies, being that - we are able to offer our clients trusted solutions and newest technologies that meet their needs and exceed expectations. We can supply solar water heating systems for both - domestic and commercial, industrial use.
