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$) are costs of copper wire,breakers, labour and margin. maybe cost of labour in Canada is high, hence the high quote. better install it urself: check Will Prowse on youtube, assembling a solar system is like a lego game
totally understandable. i am aware that prices aren't the same everywhere, thats why i decided to share prices of solar of where i am living. sharing quotes could help one another save on costs, and ur number of 4k CAD is really quite reasonable for 1.4Kw system and a 4Kwh battery (which is really a good bang for the buck, since batteries are the expensive part most of the time) but the user of the comment above me was quoted 40k CAD which is really absurd, but they didnt disclose the specifications of their system yet, so not much to judge. But solar has been really cheap for a while now. 25k CAD for a 260m² house ? maybe their house required too much climate control or they are charging an Ev, u could help assess how much solar they r installing on the roof: 5m² would correspond to 1kw of solar, if they r not installing alot of panels and yet have spent alot of money the rest of it probably went for batteries, among many possibilities..
how much solar generation capacity and battery storage are u seeking ? where i live, a 2kw solar installation without battery (grid-tied system ?) costs about 3k$. system pays itself in 4 years and rest of existence is powered by free energy. want batteries ? a 1kwh costs about 300$. where i live 4kwh/day is more than enough, sometimes 10kwh/day in extreme heat/cold. but i guess american needs could differ (30kwh/day maybe?). to recharge 30kwh batteries, u would need extra solar capacity (maybe 7kwc ?), and that would run at 9k$, add 30kwh batteries ? another 9k$.. idk what the 50k CAD are for
probably when using carbon cathodes instead of cobalt, the energy density drops from 300wh/kg to just 150wh/kg, so u would need extra anode/electrolyte mass to store the same amount of energy.i bet that those prices hikes are a result of diversion from rare earth metal mining..but just a guess
multinationals should be banned from making subsidiaries in tax heavens (for exemple, Ireland) The Irs knows this but lobbying money prohibits them from achieving anything substiantial
installing solar plants in arid regions should compensate for the energy needs of those vertical farms, no ? also climate controlled farms should save on water consumption since water evaporation is minimized. also a vertical farm with a studied location is probably beneficial from a business standpoint: the weather is more predictable inside a vertical farm instead the one of an open field. climate change and unpredicted weather is what made agriculture energy-hungry.
Antitrust laws were demolished so tech giants could acquire whichever company they feel like and kill competition from day 1. Coro Doctorow addressed this in detail in his book
luckely everyone has become wary of what these tech bros startups are all about. Tech companies like this just add extra steps to a preexisting business and pride themselves of being innovative
