Grid-Aware Solar Intelligence

Solar savings estimates you can actually rely on.

Most solar calculators are built to impress, not inform. ShiftAI models real Ontario grid conditions — time-of-use pricing, export limits, your usage patterns — and gives you a conservative, honest range.

The Problem

Other tools are built to close deals.
ShiftAI is built to be accurate.

Ontario's electricity system is complex. Flat-rate estimates miss TOU billing, export limits, and usage timing. That gap between the pitch and the bill is where trust gets lost.

Flat-Rate Assumptions
Ontario runs time-of-use and ultra-low overnight (ULO) billing. Tools using flat rates overstate savings by 20–40%.
Grid Export Limits Ignored
Your local distribution company caps how much you can push back to the grid. Most tools pretend that limit doesn’t exist.
One Inflated Number
A single optimistic figure hides the realistic range. Homeowners sign based on the ceiling, then get disappointed by reality.
ShiftAI Models All of This
TOU/ULO rates, real export limits, your actual usage timing, and three scenario outputs — with the conservative estimate front and centre.

How It Works

Four steps from address to answer.

ShiftAI runs an hourly simulation across all 8,760 hours of the year — overlaying solar production, your consumption patterns, and Ontario time-of-use pricing.

Methodology

We document what we refuse to model
as clearly as what we do.

No proprietary black boxes. No speculation on future rate hikes. Every data source is public and verifiable.

What We Refuse to Model
Future electricity price changes
We use current, approved OEB rates only. Rate escalation speculation adds uncertainty we’re not willing to put in front of homeowners.
SREC and carbon credit value
Volatile and policy-dependent. Consult a financial advisor if these are relevant to your situation.
Unforeseen maintenance costs
We assume a properly maintained system. Equipment failure and weather damage are not modelled.
Professional assessment replacement
ShiftAI is a modelling tool. Always confirm with a qualified installer and ESA-licensed electrician before proceeding.
