3. Design and Proposal: 

The installer will create a custom system design for your home based on the site assessment. This design includes the number of solar panels, their placement, and the type of inverter and mounting system required. You will then receive a proposal that outlines the system specifications, costs, and potential financial incentives or rebates.

4. Financing and Permits: 

If you need financing, this is the stage where you can explore various options, such as solar loans, leases, power purchase agreements (PPAs), or cash purchases. The installer will handle the necessary permits and paperwork required by local authorities, including obtaining utility interconnection agreements.

5. Installation: 

Once the permits are approved, the installation process begins. The installers will start by securing your roof's mounting hardware. Then, they will install the solar panels in the designated locations. The solar panels will be interconnected, and the inverter, responsible for converting the DC power produced by the panels into AC power suitable for your home, will be set up.

6. Electrical Work and Connection: 

The electrical connections are made after the panels and inverter are installed. This involves wiring the solar system to your home's electrical panel and installing a bi-directional meter to measure the electricity generated and consumed. The system will also have appropriate safety features, such as disconnect switches.

7. Inspection and Approval: 

Once the installation is complete, a building inspector or a representative from the local authority will visit your property to ensure that the installation meets all the necessary codes and regulations. If any issues are identified, they must be addressed before final approval is granted.

8. Activation and Monitoring: 

After the inspection is passed and the necessary approvals are obtained, the solar system can be activated. The installer will help you activate the system, which may involve coordinating with your utility company to switch to net metering or other relevant programs. You can then start generating your clean electricity.

9. Maintenance and Support: 

Solar systems are generally low maintenance, but periodic inspection, cleaning, and monitoring are recommended to ensure optimal performance. Many installers offer maintenance packages or ongoing support to address issues or provide system monitoring services.

Advantages Of Solar Installation For Home

Cost Savings 

One of the most compelling reasons to invest in residential solar panels is the potential for long-term cost savings. You can eliminate your reliance on traditional utility providers by generating your electricity. As a result, you can significantly lower your monthly electricity bills. 

Over time, the savings can add up to thousands of dollars, making solar panels a wise financial investment. Many regions offer incentives, such as tax credits or rebates, that reduce the upfront cost of installing solar panels.

Energy Independence

Residential solar panels allow homeowners to become more energy independent. Instead of relying solely on the power grid, you can generate clean energy on your property. This reduces your vulnerability to electricity price fluctuations and potential power outages. Solar panels give you more control over your energy consumption and production, leading to greater self-sufficiency.

Environmental Benefits

Solar energy is a renewable energy source. Installing residential solar panels can significantly contribute to a more sustainable future. Solar power does not produce greenhouse gas emissions or other harmful pollutants associated with fossil fuel-based electricity generation. By choosing solar, you actively combat climate change and promote cleaner air and water for your community.

Increased Property Value

Residential solar panels can increase the value of your property. Studies have shown that residences with solar panels sell at higher prices and have shorter selling times than non-solar homes. Potential buyers are attracted to reduced energy costs and the environmental benefits of solar energy. Installing solar panels can be seen as a valuable asset that enhances your home's overall appeal and marketability.

Positive Community Impact

By adopting residential solar panels, you set an example for your community and encourage others to embrace renewable energy solutions. The collective adoption of solar power can significantly create a more sustainable energy landscape for everyone.

Pre-Installing Considerations For Your Residential Solar Panels



System Size

Your solar system will depend on various factors, such as your energy consumption, available roof space, and budget. Review your electricity bills to determine the appropriate system size to understand your average monthly usage. 

Consider the number of solar panels needed to offset a significant portion of your electricity consumption. Consulting with a solar installer or energy professional can help determine the optimal system size based on your specific needs.

Roof Orientation and Tilt

In Canada, the optimal orientation for solar panels is generally facing south to maximize sun exposure. However, east or west-facing roofs can still be viable for solar installations. Assess the orientation and tilt of your roof to determine its suitability for solar panels. A steep tilt angle is typically ideal for efficient energy generation, but solar panels can be installed on roofs with various slopes.

Shading Analysis

Assess any potential shading issues that may affect your solar system's performance. Nearby buildings, trees, or other obstructions can cast shadows on your roof, reducing the efficiency of solar panels. Conduct a shading analysis to identify significant sources throughout the day and year. Advanced tools, such as solar energy software or on-site shading analysis, can help provide accurate data.

Roof Condition and Structural Assessment

Evaluate the durability of your roof to ensure it supports the weight of solar panels. Assess any signs of damage, leaks, or structural issues that might need repair or replacement before installing solar panels. It's essential to have a stable and well-maintained roof to support the longevity of the solar system.
