“Mashu Energy sized our home system perfectly — we barely notice load-shedding anymore and our bill has dropped noticeably.”
“Our rooftop solar cut daytime energy costs and the monitoring dashboard tells us exactly what we are saving.”
“They understood mining electrical standards and delivered a compliant substation upgrade without disrupting production.”
Questions before you commit.
Do I need a Certificate of Compliance (COC)?
Yes. Any electrical installation, including solar and battery systems, must be covered by a valid COC. Mashu Energy issues and updates COCs as part of every installation and remedial project.
Can solar keep my home running during load-shedding?
A hybrid solar system with battery storage will keep your essential circuits running during load-shedding and outages. We size the battery around the loads you most want to protect.
How much does a solar system cost?
Cost depends on your energy usage, roof space, and how much backup you need. We quote after a free assessment so the system is sized correctly and there is no wasted spend.
Do you service commercial, industrial, and mining sites?
Yes. We deliver solutions from single residential rooftops to commercial plants, industrial facilities, and mine sites — including substations, distribution, and compliance.
Which areas do you cover?
We are based in South Africa and deliver projects nationwide, from residential neighbourhoods to remote industrial and mining operations.
What happens after installation?
We test and certify the system, walk you through how it works, and offer ongoing monitoring, maintenance, and support to protect your investment.
