My rank is the below of rank list

There are no submissions on your Zindi account my friend

But,I submitted my submission

You are likely overfitting to your validation data or there could be something wrong about the way you are computing the MAE score .

Firstly,I make tow MAE score for two target variables solar panel and water heater, and I take the MAE average.

mae_total=((mae_panel + mae_boil)/2)

You are probabily overfitting on validation data. Try to visually count some of the panels and boilers in the test set and see if your model predicts same. Especially for those with higher counts from sat images.
