Competitive capital cost, no maintenance costs and a long lifetime.
Converts a standard electric geyser into a solar PV water heater. No element change and no inverter or batteries needed.
Easy compliance with SANS 10400-XA2 and can help achieve EDGE certification.
The Elon 100 Solar PV Water Heating unit
The Elon range operates on a basic principle: enabling a direct connection of electricity produced by solar PV panels to a standard electric geyser. This means the Elon can run completely off-grid, or with AC power as back-up… No inverter or battery needed!
A smart and simple way for property developers to meet SANS 10400-XA requirements while ensuring that future homeowners have access to a reliable, maintenance-free solar PV water heating solution that will also translate into years of cost savings.
Designed to match the decades-long lifetime of solar PV panels, the Elon is robust, has over- and undervoltage protection. Up to 5-year extended warranty.
"Build-to-rent" property developers can take advantage of the Section 12B tax savings.
Thousands of Elon solar PV water heating systems installed across South Africa. No maintenance and simple user controls means fewer callouts and user support requests.
The Elon is the most affordable solar PV unit in its class.
Easy installation: No need to replace elements or install and wire multiple components.
Over 90% efficiency and only requires 20V to switch on under load. This means the Elon can start heating the geyser in lower-light conditions (cloud cover; Winter; earlier in the mornings and later in the afternoons).
