kesian T20.

if u want the contra way, should have do solar properly to have battery storage and have your household electricity to draw from the solar generated electricity first and the only topup via TNB electricity. not "sell" the electricity to TNB.. trololo... just like currency exchange, customer selling to bank, always at a "lost"...

yeah, no point install solar(connected to tnb grid) where the generated electricity > your average usage during the day, only waste of money coz the unit u sell also not really cover much in comparision with the tax and whats not.. better just save up the panel cost and install just enough.

rich.. but not too smart.

depend on what "logic" TNB use.. what they do is more like buying and selling of electricity... "selling" of electricity from solar user only occur when there are surplus of electricity during the day, if not, then no "selling" occur. when TNB "buy" your electricity, it is this rate. when u "buy" electricity from TNB is that rate, there's that. similar to currency. u sell to bank USD in the morning, then buy from bank USD in the night, will bank just "give back"(contra) the USD you sold earlier?

what lapiji mention is renting out our roof space.. arguably that a better income than this "investment" shit coz you dun have to throw load of money for the installation, but rather just collect the rental fees.

yes, if it is used/install for the right conditions. if you dun use much electricity during the day, i would say better forget it. the export/selling part to TNB is not worth it.

buy 2 EV... rotate charge during the day, spend more to solve problem that does not exist in the first place.

most likely coway machine. fridge these day pretty efficient, especially if you dun open it much.. coway machine that keep water at/near boiling temperature on the other hand.. not so.

just get something like this and plug it in on the appliance u want to monitor.

depend.. not all EV support bi directional charging. also if you do that, most likely not enough power to use the car when u need it. might as well spend half of the price and buy a big ass LiFePO battery for that kind of ussage.
