As winter sets in, the white stuff starts falling from the sky. Many of a critic of solar panels point out that this is why solar never works in Canada. And yes, unsurprisingly, solar panels covered with snow do not produce electricity. But what did surprise me is how easily snow slides off the panelsContinue reading “Snow and Solar”

Lately several news items have cropped up suggesting that cheap solar is killing the grid (source). The too long did not read version roughly goes like so: Net metering results in a revenue loss to the utility, the then cash strapped utility cannot afford to provide necessary upgrades and falls into disrepair or has toContinue reading “Is cheap solar killing the grid?”

For a long time now, there have been aftermarket specialists offering battery upgrades for the Nissan Leaf. The newer batteries have typically been sourced from crashed Leafs.

Well, seems the inflation ghost is finally creeping into power pricing in Ontario. To little fanfare, the Ontario energy board announced a price increase for residential electricity rates in Ontario. On the ultra-low overnight rate (which I use), the peak rate went up a whopping 38% (from 28.4 to 39.1 c/kWh). Lets look at theContinue reading “Pricing update for Ontario”

Having had solar for six months or so, three of which my utility has given me credits for excess solar, lets look back and see how the financials are stacking up.
