Berlin-based climate research institute Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study indicating that, in the last decade, the cost of solar power has dropped by 87 percent, and the cost of battery storage by 85 percent.
i dont live in Canada, but that quote was from a third party solar installation company, that gets a license from the utility company to install a two-way electricity meter to tie the solar system to the grid. and yea those prices have been the same for a year now, if not dropped. a 2kw inverter is about 300$, 400w panel is about 100$*5=500$. meter=60$. the rest (3k$-860$=2140$) are costs of copper wire,breakers, labour and margin. maybe cost of labour in Canada is high, hence the high quote. better install it urself: check Will Prowse on youtube, assembling a solar system is like a lego game
