There's a lot of great content on PrepLounge on how to structure a market sizing e.g.
----
Think through this problem from first principles which means there are different approaches you can take e.g.
- Residential vs Business solar panel owners/operators - assume a certain % penetration of solar power usage, estimate avg panels/user
- Landmass based - total roof size in a country, average % dedicated to solar panels, avg size per panel
- Energy usage basis - total energy used in a country, % renewable, % solar, kWH generated per panel, therefore inferred number of panels

General Tips for Market Sizing
- Just like in a case, make sure you understand the question - what are you really being asked to calculate
- Decide whether a top-down or bottom-up approach is best
- Figure out what you know you know, and what you know you don't know, but could estimate
- This helps you determine how to split out buckets
- Stay flexible - you can start with a "high-level" market sizing, but gauge your interviewers reaction....if it looks like they want you to do more...then go along level deeper in terms of your splits

Hello!
I would always recommend you to give it a shot and then post it here, this would help you the most.
This is a very typical market sizing case, where the key steps are:
Calculate the total population
Calculate the % of population that could be interested in this product (this could be done by clustering -the classical ones are age groups, purchaching power, etc.-)
Hope it helps!
Cheers,
Clara

It's a nice market sizing question.. First of all, it really depends on the country and what kind of energy is used in which proportions. I would start with that.
