A basic 800-watt plug-in solar kit — the configuration this campaign asks Ontario to legalize — typically sells for €279–529 in Germany (median roughly €369, or $502 CAD pre-tax after stripping VAT and converting at Bank of Canada monthly average). On a south-facing Toronto balcony it would generate about 723 kWh per year.
At Ontario's typical variable residential rate (15 ¢/kWh including energy, transmission, and distribution charges that scale with usage), that's roughly $55.31 a year in avoided charges. A median-priced kit pays for itself in 9 years 3 months — then keeps producing for another 16+ years of its 25-year lifetime. Over the panel's full life, that's roughly $794 of cumulative savings that Ontario households are currently being denied.
Assumptions skew deliberately conservative: vertical (90°) panel mounting (pure vertical is optimal only at the poles; any realistic installed tilt produces more), 60% self-consumption rate (typical households hit 70%+), 15% shading derate, and no allowance for rising electricity prices. We publish the floor, not the ceiling.

Condo units in Ontario. None of them have a legal pathway to plug in a solar panel.
The Electrical Safety Authority laid out exactly what’s needed — they’re waiting for certified products.
Toronto City Council told the ESA to make plug-in solar happen. The directive stands.
Per kWh on time-of-use peak. A balcony panel generates most power exactly when rates are highest.
Ontario applies essentially the same net metering process to a 400W balcony panel as to a 499kW commercial rooftop installation. The framework has one threshold at 10kW (above which engineering consultation is more involved) and another at 50kV (voltage class). A 400W system is 25 times smaller than the "simplified" under-10kW threshold — and still must file a net metering application with the local distribution company, sign an interconnection agreement, upgrade to a bi-directional meter, and hire a licensed electrician for the install. An appliance that draws less current than a hair dryer is treated as a generator.
Here are the regulatory changes needed and who has the authority to make them.
Bundle plug-in solar legalization into a Less Red Tape omnibus bill. This approach lets the Red Tape Reduction ministry coordinate the amendments to O. Reg. 541/05, O. Reg. 164/99, and related instruments as a single package, and frames the change in the government’s own language.
Create a plug-in generation class in the Ontario Electrical Safety Code for certified systems under 1200W. Certified equipment (UL 3700 or CSA equivalent) would meet the installation safety requirements without a licensed electrician or permit for cord-and-outlet connection only.
Create a plug-in generation category in O. Reg. 541/05 for certified systems under 1200W. Exempt from net metering application, interconnection agreement, and bi-directional meter requirement. On-site use only, anti-islanding required. The regulatory instrument already exists; the amendment is additive.
Many Ontario residents live in multi-unit buildings where rooftop solar isn’t feasible. Start the conversation with your board about balcony solar — it’s the one change that unlocks renewable electricity for renters and condo owners.
