The Future of Hot Water, Today

The Elon Smart Water Solution transforms electric geysers into smart, solar PV-ready, green appliances.
Real-time monitoring and communication delivers actionable data.

This provides ecosystem stakeholders with the necessary insights to support decision-making and proactive management & service delivery.

Simple installation with plug-and-play solar PV enables reduced reliability on fossil fuels, improving quality of life.

1 House

What is the environmental impact of installing 1 Elon solar PV water heater?

Installation of an Elon solar PV water heater with about 1 kW of solar PV in Cape Town will save about 39 tons of carbon dioxide over the system lifetime.

That’s equivalent to an average car driving 7 times around the earth!

100 Houses

What is the environmental impact of installing Elon solar PV water heaters on 100 houses?

Installation of 100 Elon solar PV water heaters with about 1 kW of solar PV each in Johannesburg will save about 4000 tons of carbon dioxide over the system lifetime.

That’s equivalent to an average car driving 69 times to the moon!

Overall Cost* for Residential Water Heating (R/kWh)

Elon Smart Water Graph

*Overall cost includes capital cost, installation, operations, maintenance, fuel cost over total lifetime. It is the Levellised Cost of Energy (LCOE)

Total Lifetime Cost (Levelized Cost of Energy)

To compare different water heating options that have different initial (capital) cost, different lifespans and different operating & maintenance cost, a common approach used is the so-called Levelized Cost of Energy or LCOE. This approach considers all these different factors to produce a single cost per unit of energy (kWh). This then enables a direct “apples with apples” comparison of different technologies and energy sources. As can be seen from the chart above, Elon solar PV is the lowest cost option on a total lifetime cost basis. Electricity from Eskom or municipalities is the most expensive way to heat water. (For more details on this analysis, see the “Levelized Cost of Energy” tap on this page.)

The Sad Truth

Over the past 15 years, South Africans have experienced dramatic electricity and water price increases whilst quality of service has been steadily deteriorating.

When you consider climate change and the fact that we are one of the worst polluters in the world (for which we also pay a price in air pollution-related deaths), it becomes clear that real change is needed.
