What would it take for our home to be Solar Self-Sufficient?

Work in progress, but I think I have the answer.

🏠 I live in an ordinary house in suburban London.
☀️ Our solar panels generate 3,800kWh per year.
🔌 We use the same amount of electricity per year.

After crunching the numbers:

🔋 Capturing all our solar excess needs a 1 MegaWatt-hour battery.

A rough calculation shows that a MegaWatt-hour battery would cost £500,000 today.

That's probably a bit much for the average home.

But battery prices have fallen 90% in the last decade.

Sodium-ion batteries are aiming for US$10/kWh.

It is possible that in a couple of decades, every home will be 🌞🔋💯

What does that do for energy prices? Productivity? The environment?

@Edent we are and will be in a phase of arbitration for the next few years, where energy price will fluctuate between high available/low cost and low availability/highcost. The more batteries there will be, the fluctuations will vanish and this is where we enter unchartered territory. I have yet to meet an energy expert who could answer what that market will look like. Especially the dynamic between energy and grid provider and the resulting conflict between grid costs vs production costs.
