Sounds like you should install double what you think you need. Reason? The panels will start losing efficiency over time and your electricity usage over time will do nothing but grow. That's very common.
Dude.
Those panels lost only 20%, so far from half, in 32 years.
That's impressive.
I didn't say they lost half but they lost 20% so you need to have at least 120% today and then you need to account for the fact that you will get more electric devices in the future. How are you going to charge your electric car if you don't have the electric to do it? So therefore you should probably double it.
