Solar panel calculators
Quick first answers while you plan a solar energy system: how many kWp, how many panels, how much roof area?
Short answer
The calculators show the approximate size of your solar energy system project before you ask for bids. Results are estimates based on province-level average yields and general assumptions; final figures come from a site survey and the firms' bids.
Available tools
Tool results are estimates; final figures come from a site survey and the firms' bids.
How to use the results
- As a starting point for comparing the system sizes firms propose.
- To see roughly whether your roof can cover your needs.
- To enter the approximate capacity correctly in your project request.
Tool results are a first assessment of your renewable energy investment; they do not replace a bid or a guarantee.
Next step
Once you know the approximate size, you can create a project request and read what drives the price on solar panel cost.
Frequently asked questions
Are the calculators free?
Yes. The calculators are free and you do not need an account to use them.
How accurate are the results?
Results are estimates. Site-specific factors such as shading, roof pitch and orientation, and equipment choice change the final figure; it is set by a site survey.
