The Short Answer
Solar X is now a registered Green Button Connect My Data provider in Ontario. Instead of sending us a year of hydro bills, you approve the connection on your utility's own secure portal, and your real electricity usage, including detailed interval readings, comes directly to Solar X. We use it to size your solar and battery system on how your home actually uses power. Solar X has successfully completed all of Hydro One's requirements to use Green Button Connect My Data.
Free, takes a few minutes, no obligation.
What's new
A solar quote is only as good as the usage data behind it. Until now, that meant finding twelve months of hydro bills, photographing them and sending them in, and a monthly bill still only shows totals.
Solar X now has a direct API connection to utility Green Button Connect My Data, the secure standard every Ontario electricity utility is required to offer. With one approval on your utility's website, your usage history arrives directly from the utility's system to ours, in detail, and ready for your design. No middleman, no file uploads.

Why it gives you a better solar quote
No bills to chase
Skip the paperwork. One approval on your utility's site replaces a year of bill photos and scans.
Sized on how you really use power
Interval readings, often hourly, show when your home uses electricity, not just how much. That shapes the right system size and how much a battery can shift to cheaper hours on Time-of-Use or Ultra-Low Overnight rates.
Every season included
Your usage history covers summer air conditioning and winter heating, so the design reflects your full year, not one month.
Secure and in your control
You approve the connection on your utility's own portal. Solar X never sees your utility login, and you can stop sharing at any time.

Why every Ontario homeowner can use Green Button
Ontario made Green Button part of the rules. Under Ontario Regulation 633/21, electricity and natural gas utilities in the province must offer Green Button Connect My Data, certified by the Green Button Alliance, with a deadline of November 1, 2023.
By November 2023, the Green Button Alliance reported that 55 Ontario utilities' platforms were certified, covering nearly all of the province's 5.4 million residential and business electricity customers. Companies like Solar X then register with each utility and pass its testing before they can receive customer data.
