Show bill pls

Example Exhibit A

It's because during daytime the solar energy get consumed by your household before being exported away. I also noticed the amount of total electricity consumed on my bill is less than before solar installation.

Again i will reiterate. My latest 3 months bill before solar installation is RM800+ and RM900+.

After installing solar my consumption drop to RM500-600. I theorize that it's because during daytime all the solar energy i generated get consumed by the house first before diverting the excess to TNB. In short the price difference probably is the amount of electricity i used during daytime which is about rm200-300.
1. probably because during daytime the energy generated get consumed first before sending the excess to TNB.

2) Yes need to remove panel only repair. so u have to arrange them to come buka, then roofer repair, then arrange them come pasang back . that's why it's very important to make sure your roof no such issue before install. They recommend new house stay few years no issue just install.
yes. in fact it didnt degrade. Because my uncle installed them 2010. Until now he said the energy produced same only. Already 10 years no different. Main reason why i feel confident to install.
