if this is true, it is clearly a robbery on the part of the government, this is absurd, why would the man be taxed? anyway, maybe this is just an isolated incident, putting up a solar panel is very expensive, but imagine the savings on the part of the owner, it is very economical and environmental, maybe the installation and all that is why he was taxed.
Well I am amazed with this thing, how can a person in single capacity is manufacturing his own electricity. How is that possible? There is no option for any person in any country to manufacture electricity and government is unaware of it. But yes, many people have installed solar panels on their roofs and running their homes on it but still they must pay tax as they are living in that country.
What I think is, as far as he is not getting any electricity bill from government which he definitely should be receiving if he has really owns electricity generating by any means, it is well and good. But he cannot run from paying other taxes. If he thinks he can live without paying a single penny to the state, he needs to wake up from his dream soon.
