Cape Town homeowners with solar can offset their entire municipal bill (electricity, water, waste removal) by feeding excess power back to the grid. But only once your system is registered. We handle the application. You get the cash back.
"Most Cape Town solar systems are done correctly.
The solar paperwork almost never is."
Your installer's job was the panels and the inverter. The City of Cape Town's solar registration — e-Services submission, ECSA professional sign-off, grid connection approval — is a separate process that most homeowners discover only when they try to export, or when they sell. Without it, your exported power earns nothing. We handle it so you don't learn that the hard way.
We review your system specifications, existing documentation, and grid connection to confirm solar export eligibility before any paperwork begins. No surprises.
We prepare and submit your complete application via the City of Cape Town's e-Services portal — including all required technical documents and ECSA professional sign-off.
We track your application status, respond to any City queries, and confirm when your system is cleared for export. You receive notification when credits begin appearing on your municipal account — offsetting electricity, water, and solid waste charges. If your account runs into credit after all municipal charges, the City will refund the balance.

Incentives offset your total municipal account — electricity, water, and solid waste. Cash refunds only apply if your account is in credit after all municipal charges are settled. Figures based on published City of Cape Town generation offset incentive rates and average export yields for a south-facing 10kW installation. Verify current rate before submitting.
