Wait after you getting your EV first then baru think about solar

Are you going to apply for NEM? Or selco (off-grid)?

If selco, you can reduce your bill theoretically to RM0 because there wont be any limit in terms of solar pv capacity, but you need to get an energy storage system if you plan to continue use the energy at night.

But, if you plan to go for NEM (grid connected), the current capacity limit is 85% of your maximum demand, so you still have to pay for TNB bills.

Rule of thumb for any solar installation:

1. If you live in the northern hemisphere, your solar panels should be facing south (and vice versa).
2. Angle of the solar panels should be according to the latitude.

These two are just the starting points, actual calculations for optimal placement, angle and directions of solar panel depends on your location, surrounding trees/buildings, and many other factors.

In some areas, facing west would be the most optimal direction in certain months of the year, but in general, the panels should face south.

While it is cool looking tech but it’s not feasible. Better stick at one position and be done with it.

Yeah at least there’s a minimum bill
