i think its how it works

they install solar panels, you pay partial price, RM1500

then they use your roof, to sell you electricity, at RM0.46 per KW, u save RM0.11 per KW after hitting the maximum tariff at about rm500.

but you paid them already RM1500, until you use up to 13636 KW in total, you cant make back the initial investment.

i honestly think u better diy it, they sell you 0.46 per kw, which i think its expensive(unless you dont put your roof into calculation). cause you cant install your own panels anymore after you go with them, your roof space is gone, and they also need some other than roof space in your house. they use your space, and sell you 0.46 per kw.
