How to Prepare Your Calgary Home for Solar Panels

If you’re considering making the switch to solar power, you’re already on the path to lower electricity bills, greater energy independence, and a more sustainable home. But before the panels go up, it’s important to make sure your home is ready for the transition.

Preparing your Calgary home for solar isn’t a complicated process, but there are a few key things to think about ahead of time. Whether you’re just beginning to explore solar or have already booked your consultation, this guide will help you understand what steps you can take to get your home solar-ready.

‍

1. Assess Your Roof’s Age and Condition

Your roof is the foundation of your solar installation. Before solar panels can be installed, it’s important to know whether your roof is in good enough condition to support them for the next 20–30 years.

A few things to check or ask your consultant about:

• Age of your roof: If your roof is nearing the end of its lifespan (typically 20–25 years for asphalt shingles), you may want to consider replacing it before going solar.
  
  
• Visible wear or damage: Curling shingles, leaks, or soft spots may need repair prior to installation.
  
  
• Material compatibility: Most common roof types in Calgary — asphalt, metal, and flat roofs are solar-compatible. Your installer can confirm this during your site visit.
  
  

When in doubt, your solar provider will inspect your roof during the consultation and let you know if any work is required beforehand.

2. Understand Your Home’s Sun Exposure

Solar panels generate electricity from sunlight, so maximizing sun exposure is key. A good solar consultant will analyze your home’s orientation, shading, and roof angle, but you can start by asking:

• Does your roof face south, southeast, or southwest? (These directions typically receive the most sun in Calgary.)
  
  
• Are there trees, chimneys, or nearby buildings casting shade on your roof?
  
  
• Is your roof mostly free of snow and debris in the winter?
  
  

If your roof is partially shaded, your installer may be able to design around it, or suggest using optimizers or microinverters to minimize production loss. Either way, the goal is to get a clear understanding of your solar potential.

3. Review Your Electrical Panel

Solar systems need to connect to your home’s main electrical panel. If your panel is outdated, maxed out, or otherwise incompatible, your installer may recommend an upgrade before installation.

This is something your solar provider will assess for you — but it’s good to know ahead of time that a panel upgrade could be part of the overall scope.

‍

4. Gather Recent Electricity Bills

Your monthly energy usage helps determine how large your solar system should be.

To prepare, gather the last 6–12 months of electricity bills. Most providers in Calgary allow you to download your usage history online. Your solar installer will use this data to design a system that offsets as much of your usage as possible, without overbuilding.

This also helps identify seasonal trends, which is especially useful in Alberta where energy use can vary dramatically between winter and summer.

5. Consider Your Long-Term Plans

Solar is a long-term investment. While it starts saving you money from day one, the real financial return builds over time, typically 10 to 25 years depending on your usage and system size.

As you prepare for solar, consider your future plans:

• Are you planning to sell your home in the next couple of years?
  
  
• Will you be adding more electrical demand (like an EV charger)?
  
  
• Do you want to add battery storage or expand your system later?
  
  

These aren’t dealbreakers, in fact, solar can boost your home’s resale value, but they’re worth discussing with your provider to ensure the system is designed with flexibility in mind.

6. Clear Access for the Installation Team

Installation usually takes 1–2 days and is minimally disruptive. But there are a few things you can do to make the process smoother:

• Clear your driveway or garage if it’s where the team will need to work.
  
  
• Make sure gates or fences are unlocked so installers can access the electrical panel and roof.
  
  
• Secure pets during the installation for everyone’s safety.
  
  

Your solar provider will give you a checklist in advance, but preparing a bit ahead of time helps the install go as smoothly as possible.

7. Work with a Local, Experienced Installer

The most important part of preparing for solar is choosing the right partner.

Working with a trusted Alberta-based installer like Orizon Energy means you’ll have expert guidance from start to finish. From roof assessments and design to permitting and post-installation support, you’ll be in good hands every step of the way.
