Solar Panel Setup in Canada

The story of solar energy  in Canada is both intriguing and promising. The country, known for its long winters and sizeable hydroelectric resources, is also stepping into the spotlight for its adoption of solar energy and solar panel setup, offering an environmentally sustainable solution for its energy needs.

Brief History and Growth of Solar Energy in Canada

Early Beginnings

Alberta’s Culture and Tourism article shares that the exploration of solar energy in Canada dates back to the 1970s, primarily driven by the global oil crisis. Yet, the technology was still in its infancy, with high costs.

Growth in the 2000s

As the technology evolved and became cheaper in the early 2000s, several provinces started adopting solar power. Ontario was particularly proactive, launching the Feed-In Tariff (FIT) program in 2009, significant in accelerating solar installations.

Recent Developments

Solar panel installations have increased nationwide over the past decade. Alberta, known for its oil sands, has also made significant strides in solar adoption. The price per watt of solar installations has dramatically decreased, making it an increasingly economical choice for households and businesses.

Current Trends and Future Glances

  • Variety in Use: Solar power is diversifying. Beyond rooftops, it’s used in community projects and remote areas, broadening its impact.
  • Tech Innovations: Solar panels are upgrading, becoming more efficient and adaptable.
  • Bright Future: Creating jobs and helping Canada move towards a greener future with plans for zero carbon emissions by 2050.

Components and Setup of Solar Panels

Choosing the right spot for your solar panels is like choosing the best beach spot on a sunny day. It would help if you had maximum sunlight, a good angle, and no big trees or umbrellas blocking your sun.

  • Sunlight: Opt for areas with maximum sunlight hours and intensity.
  • Geography: Consider land features; hills or valleys might affect sunlight.
  • Shadows: Stay clear of obstacles like trees or buildings that cast shadows.

  • Series vs. parallel connections: Series means they’re connected one after another, while parallel means each panel connects directly to the main power source. Series boosts voltage, while parallel boosts current.
  • Optimizing for maximum sunlight absorption means positioning your panels to soak up as much sun as possible, like turning your beach chair to face the sun.

Solar panel installation isn’t just about harnessing sunlight; it involves strategic planning, budgeting, and abiding by local regulations.

Financial Options

The Canadian government provides incentives to promote solar use. Check if any rebates or incentives are currently available in your region.

Financing and Leasing Options:

Financing

Leasing

Buy with loan, own the system

Rent system, lower upfront cost

Benefit from tax incentives

No ownership, but fixed monthly rate

Regulatory Requirements

Getting solar panels isn’t just about buying and setting them up; you need the right permissions to ensure you follow the rules.

Necessary Permits and Documentation:

You need one for solar installations like a construction permit. This ensures safety and proper integration with local power grids.

Standards and Safety Regulations:

Federal Standards

Local Regulations

Set by national bodies, applicable everywhere

Specific to your municipality or province

Selecting Solar Panels

Areas where flexibility and lightweight attributes are essential

Inverters and Battery Systems

Harnessing solar energy is one thing; optimizing its usage for our homes and devices is another. This is where inverters and battery storage systems come into play.

Inverters

At its core, an inverter’s job is to convert the direct current (DC) electricity that solar panels produce into alternating (AC) electricity that our homes and devices use.

Type

String Inverters

Microinverters

Design

One inverter for many panels

Each solar panel gets its own inverter

Flexibility

Less flexible; all panels depend on one inverter

More flexible; each panel operates independently

Efficiency

Efficiency may drop if one panel underperforms

Better efficiency as each panel’s performance doesn’t affect the others

Cost

Generally less expensive initially

More expensive upfront, but can be cost-effective due to higher efficiency

  • Reputation: Check for brands with a solid reputation and positive customer reviews.
  • Warranty: A longer warranty indicates confidence in the product’s longevity.

Safety Precautions

Always follow guidelines and use the right tools. Wear protective gear, especially when working on rooftops. Consult with experts if unsure.

Professionals are trained in safety protocols. They ensure a secure installation.

Preparing the Site:
  • Check and clear the area where the solar panels will be installed. Ensure no obstacles or potential hazards exist.
  • Considering optimal sunlight exposure, map out where each panel will go based on your solar design.

 

Mounting the Panels:
  • Set up the mounting system first, whether it’s ground or roof mounts. Ensure they’re secure and stable.
  • Attach solar panels to the mounts. Ensure they’re aligned properly and firmly secured.

 

Connecting to the Grid/Inverter:
  • Route the wiring from the solar panels to the inverter. Make sure to hide and protect wires to prevent wear and tear.
  • Connect the panels to the inverter, ensuring that the DC from the panels gets converted to AC by the inverter.
  • If you connect to the grid, coordinate with your local utility to ensure a smooth connection.

Maintenance

Solar panels thrive with proper care like any other major equipment in your home. A well-maintained system can serve you efficiently for many years.

Frequency

Method

Regular (Quarterly)

A gentle rinse with water to remove dust and light debris.

Annually

A more thorough cleaning using soapy water and a soft brush, followed by a rinse.

As Needed

Removal of snow in winter or bird droppings as soon as possible to prevent efficiency reduction.

  • Avoid walking on the panels.
  • Trim nearby trees or plants that might drop debris or cast shade on panels.
  • Install critter guards if birds or animals pose a potential problem.

Using Monitoring Software: Most modern solar systems use software that lets you monitor the system’s performance in real-time. This helps in catching inefficiencies quickly.

Adjusting for Seasonal Changes: As the sun’s position changes seasonally, adjusting the tilt of your panels can optimize sunlight absorption. Some tracking mounts do this automatically.

Common Issues and Fixes:

Issue

Fix

Reduced Power Output

Clean panels, check for obstructions or shade, ensure connections are tight.

Inverter Display Errors

Refer to the inverter’s manual for error codes. Some issues might be fixed by restarting it.

System Not Working

Check circuit breakers, connections, and ensure the inverter is on and working.

Seeking for Solar Professional Help?

Call a professional if basic troubleshooting doesn’t resolve the issue or if there’s visible damage to panels or equipment. Regular expert inspections can preemptively identify potential problems, ensuring your system remains at peak performance.

FAQs

Yes, solar panels work in cloudy conditions and during winter. However, their efficiency might be reduced compared to sunny days. Snow can block sunlight, but panels are designed to withstand winter conditions, and some snow can even slide off due to the panels’ angle.

Savings vary depending on your local electricity rates, solar policies, and installation size. Generally, most homeowners can recover their investment in 8 to 12 years and then enjoy reduced or nearly zero electricity bills.
