About us
A solar company run by installers, not salespeople
Deye Sunsynk RSA Energy designs, supplies and installs hybrid solar and storage systems across gauteng, limpopo, mpumalanga, north west & nationwide projects. We've built our reputation on the unglamorous things: correct cable sizing, honest system sizing, tidy boards and paperwork that passes inspection.
Our approach
Every system we build has to make financial sense
Solar is a capital investment, not a gadget. Before we quote, we audit your loads, check your tariff structure and model what an outage actually costs you. Sometimes the answer is a modest backup system; sometimes it's a full off-grid build. We tell you which — even when the smaller number is the right one.
Then we install to standard: SANS-compliant DC protection, labelled boards, earth testing, surge protection and a documented commissioning report. Your installation is registered for full manufacturer warranty on the day we finish.
Design before hardware
We start with your consumption profile and tariff, not a catalogue page. The system follows the data.
Our own teams
No subcontracted labour on the roof. The people who quote you are the people who commission your system.
Measured results
We hand over commissioning readings and monitor performance so savings are proven, not promised.
Long-term relationship
Batteries live for a decade. So does our support, including firmware, tariff changes and expansions.
