Canadian Solar Blog
Long-form guides on Canadian solar — residential, farm, and commercial pricing, payback, rebates, net metering, and system design. Every post is updated as programs, rates, and technology change.
Canadian-specific solar information — written for Canadian winters, utilities, and tax code
Most solar guides online were written for American readers. American rebates, American utility rate classes, American electrical code, American climate zones. For Canadians trying to make a $20,000 to $200,000 decision, that content is at best misleading and at worst wrong on the numbers that matter most — the 30% Clean Technology ITC applies to Canadian corporations only, Canadian Electrical Code Rule 84-024 differs from NEC 705.12 on panel placement, and provincial utility rate structures range from Alberta's deregulated Solar Club tariffs to Hydro-Québec's flat Rate D.
Every guide here is written against the current rate card, program status, and tax guidance for a Canadian audience. Pricing figures come from installer quote data in each province, cross-referenced against Natural Resources Canada and provincial utility filings. Rebate statuses are re-verified on the first Monday of every month and closed programs are flagged with an in-article banner that doesn't get removed just because the article still ranks — closed is closed. Articles that model payback use PVGIS live irradiance for the exact Canadian coordinates, not a US-national average.
We cover three audiences. Homeowners get system sizing, payback by province, winter performance, financing options, and the panel-upgrade math under CEC Rule 84-024. Farm operators get the federal Clean Tech ITC + Class 43.1 CCA treatment, provincial farm-energy programs (PEI AESPP, Hydro-Québec Solutions efficaces, Alberta ag-micro-gen), agrivoltaics case data, and roof-vs-ground mount economics for barns and farm buildings. Commercial and industrial buyers get province-specific guidance (Ontario IESO LT2, Alberta AUC micro-gen, BC Hydro business rebate), demand-charge shaving math, battery storage ROI, and worked ITC examples for incorporated buyers in different tax situations.
Every article publishes a Dan Carls editorial byline, an updatedISO JSON-LD field so AI crawlers (ChatGPT Search, Perplexity, Claude, Gemini) see the freshness date, and FAQ Q&A blocks that render in Google's rich results. We cite primary sources — CRA Income Tax Folios, provincial utility rate orders, Natural Resources Canada reports, peer-reviewed research on cold-climate PV — not other installer blogs. If a number looks suspicious, it's traceable to the agency that published it.
