Frequently Asked Questions

About the Platform

Who is MyHEAT?

MyHEAT is an Albertan company known for empowering urban energy efficiency™ by helping to address one of the biggest hurdles faced when engaging homeowners about energy efficiency – its invisibility. We’ve helped millions of home and business owners visualize and compare heat loss across entire cities.

Now, we’ve expanded our offerings to promote the adoption of renewable energy generation through our rooftop solar potential platform! We are working with cities in Canada to help residents with their first step on their journey to go solar.

Solar Potential Calculations

How is MyHEAT providing this information?

MyHEAT has partnered with Google to apply the Project Sunroof technology in communities across Canada. For questions regarding the Project Sunroof technology, visit Google’s Project Sunroof FAQ page.

What size of panels are you considering in this calculation?

Panels are generally 1.65 m by 0.992 m with a nominal DC capacity of 250 W, but this can vary by location.

A solar installer provided a different estimate than this tool. Why?

Solar energy production estimates depend on many factors and sources of information may have different estimates as a result of shading, typical weather in your area and equipment used. Additionally, Project Sunroof mapping data may be from a different period in time than other estimates and may not show recent growth or removal of trees.

How should I use the estimated information for my home?

These estimates are provided solely for informational purposes. It is recommended that residents contact a qualified solar installer to complete a site analysis that provides a detailed and personalized assessment of the solar potential specific to the building’s needs.

In using the solar potential map, you expressly agree that you use it solely at your own risk and that the MyHEAT and its partners are not liable to you for any damages whatsoever including any direct, indirect, incidental, consequential, special or other damages resulting from your use of the solar potential map.

Data Coverage and Availability

I’ve searched for a building, but no solar potential data is available. Why?

Google Project Sunroof data is missing for some buildings. The rooftop that you’ve searched may be:

  1. Located outside of the current Google Project Sunroof coverage area.
  2. Be missing as a result of a gap in the available data through Google Project Sunroof. Examples of this may include garages or buildings that were under construction at the time that the data was collected.

The Google Project Sunroof data is always being reviewed to address existing issues. While data may not be available for the rooftop that you are interested in exploring at this time, you can use the calculator designed by MyHEAT for missing buildings or contact a local service provider for a detailed site assessment.

MyHEAT's calculator for missing buildings applies the estimates of photovoltaic potential and the mean daily global insolation for the region available through Natural Resources Canada. The included data uses the annual value for the south-facing orientation with latitude tilt. You can generate estimated values for your roof by entering the approximate area available for solar panels, the direction that the solar panels will be facing, and your typical utility costs. For more information, please visit the Natural Resources Canada website.

Where is the data for my garage?

Google Project Sunroof data is missing for some buildings. While solar potential data may not currently be available for the rooftop that you are interested in exploring, it may still have great solar potential. MyHEAT recommends that you contact a qualified solar installer to complete a detailed site assessment.

Adding solar panels to a detached garage roof may be an excellent option. If you add solar panels to your garage, you will not have to modify your home’s roof. Solar panels could be installed in addition to a system on your house or be installed when adding solar panels to your home’s roof is not optimal.

The Google Project Sunroof data is always being reviewed to address existing issues.

Why is the platform only applicable to single-family homes and not other, larger buildings?

The Project Sunroof technology calculates solar potential for the roof of every building. However, the system size and financial estimates found on the platform are tailored to residential buildings and do not consider units within the buildings. The economics for commercial and industrial buildings are often different from residential buildings due to different regulations, electricity prices, and solar installation costs.

Solar and Your Home

What's the first step to installing solar panels on my home?

It is important to remember that the estimates on this platform are provided for informational purposes only. If you are considering adding solar panels to your home, MyHEAT recommends that you contact a qualified solar installer to complete a detailed site assessment and visit the links included on this website to learn more about local resources and incentive programs.

How does my utility provider measure the energy that my solar panels are producing?

When you install solar panels, your utility provider will also install a bi-directional meter at your home. This allows them to track the energy flowing into and out of your house through a process called net metering.

With net metering, you only pay for the electricity that you use beyond what your solar panels can generate. It also allows your utility to provide a credit for any excess electricity produced that you do not use within your home. Any credit you receive will be based on an agreement with your utility provider.

It is important to remember that your utility provider can’t see what is happening on your side of the meter. In most cases, your financial benefits will be the result of the money you save by reducing the amount of electricity that you need your utility to provide.

How do solar panels impact my property value?

Solar panels can increase a home's value. Many home buyers are environmentally conscious and homes with solar panels may sell for more than homes without them.

What else should I consider in deciding if solar is right for my home?

This platform helps you understand the benefits of installing solar panels on your roof based on its solar potential and average costs in your region. There are other things to consider before you decide to go solar:

  1. Does your roof need replacing? Solar panels can last 25 to 40 years, so if your roof may need replacing, it is important to do it before having them installed. However, if your roof is in good condition prior to the installation, a solar array will shield and help protect the roof.
  2. Is your roof material suitable for solar panels? Many roof materials are suitable for solar, but some may be more suitable than others. For example, wood shake shingles or clay, slate and terra cotta tile roofs are generally not suitable so installers may recommend removing the tiles or shingles directly under the array which can lead to increased costs.
  3. Do you own a multi-family home? You may still be able to install solar panels on your home. However Project Sunroof does not always know which portion of the roof belongs to which address or homeowner.

If you would like to learn more about whether or not your home is right for solar, we recommend contacting a qualified service provider to get a detailed site assessment for your property.
