I was told that I can claim the CCA for my Solar panels against all Income and not necessarily only against the Solar Income. I have earned $300 but paid $30,000 for it.

I was told that I can claim the CCA for my Solar panels against all Income and not necessarily only against the Solar Income. So If I have only earned $300 in the year I installed the solar panels and paid $30,000 for the panel installation, how much can I claim for CCA? It seems weird that I have $300 Income and $15000 deduction, or does this create a Net Loss which can be transferred to future years?
