HOW SOLAR WORKS

How much does it cost to install a solar energy system? The cost of a solar energy system can vary depending on a number of factors, including the size of the system, the type of panels used, and the location of the installation. On average, a solar energy system for a residential home can cost anywhere from $10,000 to $25,000. The price of solar panel system has dropped significantly over the past decade and it’s also dependent on the location and the incentives/rebates that are available to homeowners.


A solar energy system, which typically includes solar panels, an inverter, and a mounting system, can last for 25-30 years or more. The individual components of the system may have different lifetimes, with the solar panels typically lasting the longest. However, regular maintenance and cleaning can help prolong the life of the entire system. It’s important to note that the inverter is a key component in the system that may need to be replaced after 10-15 years depending on the system usage and type of inverter.


Yes, a solar energy system requires maintenance. The maintenance requirements will depend on the type of system installed, but may include cleaning the solar panels, checking and tightening connections, and monitoring the performance of the system. Regular maintenance can help to ensure that the system is operating at peak efficiency and prolong its lifespan.


To determine if your roof is suitable for solar panels, consider the following factors:

  1. Orientation: The roof should face south to maximize the amount of sunlight it receives.

  2. Pitch: A pitch of 30-40 degrees is ideal for solar panel installation.

  3. Shading: The roof should not be shaded by trees or nearby buildings during the day.

  4. Size: The roof should be large enough to accommodate the number of solar panels you want to install.

  5. Age and condition: The roof should be in good condition and not near the end of its lifespan.


The time it takes to install a solar energy system can vary depending on the size and complexity of the project. On average, it can take anywhere from 1-4 weeks for a standard residential system to be installed, while larger commercial projects can take several months to complete. Factors that can affect the installation time include the location of the property, the type of solar panels being used, and any necessary building permits or approvals that need to be obtained.


During a power outage, a solar energy system will stop producing electricity. This is because the grid, which the system is connected to, is not providing the necessary power to keep the system running. Additionally, many solar systems include safety features that will automatically shut down the system during an outage to protect utility workers from electrical hazards. However, some solar systems are designed to provide backup power during an outage, these are called grid-tie with battery backup solar systems. These systems include a battery bank that stores energy produced by the solar panels, which can then be used to power essential loads during an outage.


Solar panels do work in the winter, but their efficiency may be lower due to the shorter daylight hours and the potential for snow or ice to cover the panels. However, even on a cloudy day, solar panels can still produce some electricity. Additionally, snow or ice can be removed from the panels to increase efficiency.








Before you begin any renovation work, you need to complete a Canada energy audit. A registered energy advisor will take a look at how your home uses energy and inform you which upgrades will assist you to save and how they interact. If you do at least 2 of the suggested upgrades, you’ll get your money back. The cost of an energy audit (up to $600) will be covered by Government of Canada Energy Rebates.
