Hundreds of people on Monday flooded a the National Energy Regulator of SA (Nersa) with objections to new draft rules that, if implemented as they stand, would require every solar electricity panel and backup power generator to be registered with the government.
Lobbying group the Energy Expert Coalition (EECO) quietly launched a web form on Sunday that allows consumers to send their comments on the draft rules to Nersa.
By early Monday evening the service had attracted more than 300 comments – and many of them were angry.
"Does the sun and it's light belong to government? Please stop this idiotic taxing of everything in SA," wrote one commenter.
"Absurdly invasive notion," said another succinctly.
The web form sends every comment to Nersa as a separate e-mail, EECO says.
Many of the comments amounted to predictions – or promises – of civil disobedience.
"I say no way and to hell with you all!!" wrote a commenter.
Those using the web form to log comments "ensure an accurate record of submissions is held by civil society (on our encrypted database) so government cannot fudge facts and figures," says EECO. "This process forms a solid foundation for a legal case should the necessity arise."
Comments on the draft rules close on 31 May.
