Do You Need Battery Backup?

Not every home needs batteries, and not every homeowner benefits from the added complexity and cost of a hybrid system. The right choice depends on how you value backup power, outage protection, future flexibility, and upfront investment.

Grid-Tied Solar System

  • Connected to the utility grid - draws power at night
  • No batteries required – excess energy is automatically sold to the grid
  • Lower upfront cost – less components than a hybrid system
  • High efficiency – all solar power is used or exported to the grid
  • No backup during outages – shuts down for safety when grid is down
  • Ideal for urban homes where grid access is reliable and no time-of-day charges.

Hybrid / Battery Ready

  • Connects to the utility and to batteries
  • Energy Independence – can power home at night and operate during outages
  • Higher upfront cost – includes battery, transfer switch and extra electrical panels.
  • Smart energy management – prioritizes solar, then battery, then grid use.
  • Backup Functionality – critical loads stay powered during blackouts.
  • Ideal for homes where grid is less reliable or that have time-of-day charges.

Comparing Inverter Types

Most homeowners don’t need to become experts in inverter systems, but they do need to understand why the inverter choice matters: it affects monitoring, expandability, shading performance, and long-term system design. In Alberta homes, the right answer depends on your roof layout, panel count, electrical service, and future plans.

How an Enphase solar system powers your home

Microinverter Setup: Enphase

One microinverter per solar panel, the DC to AC conversion happens on the roof; panels operate independently, easy to expand. Strong option for roofs with multiple faces or partial shading.

  • Ideal for urban homes with multiple roof faces. Choose this setup if:
  • Your home has multiple roof faces
  • You value panel-level monitoring
  • You want easier future expansion
  • You want to reduce the impact of one panel underperforming

String Inverter Setup: SolarEdge

Power is managed through a main inverter but power optimizers under each panel optimizes production and mitigates shading.

  • Ideal for farms and commercial buildings. Choose this setup if:
  • Your home needs a larger system strategy
  • Your electrical service and system design benefit from a higher DC/AC ratio
  • Your roof or electrical layout makes a string-based approach the better engineering fit

Comparing Solar Installers & Quotes

When homeowners compare solar quotes, they often focus on wattage and price. What gets missed is how the system is designed and installed: cable routing, aesthetics, expandability, monitoring, roof detailing, component choices, and post-install support. These decisions affect not just how the system looks on day one, but how it performs and how satisfied you are years later.

The Solar Encyclopedia was created for homeowners and business owners looking to get specific questions answered. These articles are not written by AI or any marketing company. We carefully curated the questions you are asking and answer them in the most straightforward and transparent way possible.

Frequently asked questions

From design to maintenance and weather, we tackle a few commonly asked questions. If your question isn't here, please contact us!

What is the cost of a solar panel installation in Calgary?
unlock icon turned off

Solar installation costs depend on system size (based on your home's consumption), roof complexity, electrical upgrades, with most Alberta homes landing around $2.50 –$3.15 per watt installed, $15,000 - $40,000. Use our free calculator or request a custom quote to get accurate, all‑inclusive pricing for your home.

What does maintenance of my solar system look like?
unlock icon turned off

A solar array requires almost no maintenance. Occasional rainfall keeps them clean and we always install a protective guard that keeps animals and leaves from getting under the panels. We offer inspections to check that the wires stay in place and the monitoring app will let you (and us!) know if anything isn't working like it should.

How many panels do I need?

That really depends on how much energy your home uses! If you look at your electricity bill and find your monthly usage in kWh (not dollar amount!), you can use our calculator to determine how many solar panels you will need.

Is solar worth it in Alberta?
unlock icon turned off

Solar can be a strong long-term investment in Alberta, but only if the system is designed correctly. The most common issue is overestimated savings based on unrealistic assumptions. A properly sized and engineered system (based on your usage, seasonal production, and export rates) can deliver consistent long-term value.

Why isn’t my solar system offsetting my electricity bill?
unlock icon turned off

This is usually caused by one of three issues: the system was undersized, usage assumptions were incorrect, or the homeowner’s energy consumption increased after installation.

What affects the cost of a solar system the most?
unlock icon turned off

The largest factors include system size, roof complexity, electrical upgrades, equipment selection, and whether the system is designed for future battery integration. Installation details and overall system design approach also play a significant role in total cost.

How Do Solar Panels Work?
unlock icon turned off

Solar panels turn sunlight into direct current (DC) power through photovoltaic cells; when photons hit the panel, they free electrons to create energy, and your inverter converts that DC into AC power your home runs on. Microinverters do this conversion right on the roof beside each panel, so the power coming off your roof is already in AC.

How long do solar panels last in Canada?
unlock icon turned off

Most solar panels coming into Canada are warranted for at least 25- years, and there is no reason why they shouldn't last longer.

Can Solar Panels Handle Calgary hail?
unlock icon turned off

Solar panel models entering Canada are tested for hail by throwing eleven 1-inch hail balls at 80km/h onto the panels, so they shouldn't have problems surviving hail storms. They should however be added to home insurance in case of a freak hailstorm or other uncommon events.

Do solar panels work in Calgary winters?
unlock icon turned off

Yes. Solar panels continue producing energy in winter, and cold temperatures can actually improve efficiency. When snow covers the panels after multiple freeze-thaw cycles, your solar system will halt production - but don't worry! we account for snow losses when presenting your system's annual production estimates!

What happens on cloudy days?
unlock icon turned off

Your production will drop on cloudy or hazy days, but summer days are so long in in Alberta that your solar system will still produce a sizeable amount!

What happens if I replace my roof later?
unlock icon turned off

On our site visit, we will assess your roof and ask you how old it is - if your roof is over 18 years old and depending on the condition of the shingles we might recommend replacing your roof before we install solar. If you need to replace your roof and it has solar, we would need to uninstall and reinstall the system.

Can I add batteries or more panels in the future?
unlock icon turned off

Absolutely, our systems are modular so we can add more panels if your electrical needs increase and we can also switch your system to a hybrid system (toggle between grid-tied and off-grid). If you want to add a battery to a system we didn't initially install, we would have to do a site visit to confirm your system is hybrid-compatible.

How do I compare solar quotes properly?
unlock icon turned off

Comparing solar quotes goes beyond price per watt. You should evaluate system design assumptions, production estimates, inverter selection, monitoring capabilities, expandability, and installation quality. Two similarly sized systems can perform very differently depending on how they’re designed and installed.
