Adding Solar Panels to Existing System: Boosting the Charge!

Are you ready to maximize the power of your home’s solar panel system? Adding more solar panels to your existing system is a wise move. It helps you maximize energy savings and reduces carbon emissions further.

Ontario is an attractive site for solar power generation due to its ample sunshine (an average of 2,100 hours per year). Not only will improving your solar energy system boost your home’s energy efficiency, but it will also help you save money on your electricity bills and contribute to a more sustainable future.

In this post, we’ll look at the advantages of incorporating solar panels into your present setup, as well as crucial elements to consider, such as local restrictions, available space, and the cost and efficiency of the panels.

Is it Possible to Upgrade or Add Solar Panels to Your Existing Solar Panel System?

The answer is a resounding YES! Indeed, updating your solar energy system can have various financial and environmental benefits.

Ontario is an attractive location for solar power generation due to its ample sunlight (an average of 2,100 hours per year). The Ontario government has set a goal of reducing greenhouse gas emissions by 50% by 2030, and they have implemented incentives and initiatives to stimulate the use of solar power.

For example, the province has a Net Metering program, which allows you to earn credits on your power account for any excess solar energy you generate and transmit back to the grid.

When Do You Need to Add Solar PV Panels to Your Existing Solar System?

You might be wondering when you should add them. Solar PV panels are becoming increasingly popular in Ontario, Canada, due to their potential to save money on utility bills and lessen carbon emissions.

Consider some factors to see if installing solar PV panels is the best option for you:

Energy Needs

Examine your energy consumption to see if you require more electricity. You can analyze your electricity bills and calculate your energy consumption. If you use more energy than your current solar system can offer, adding solar PV panels can help you meet your energy needs.

Available Space

Do you have adequate room to put more solar panels? Insufficient roof or ground space free from obstructions like buildings or trees is necessary for solar PV panels. It would help if you also considered any local legislation or limits that may apply to solar panel installations in your area.


The cost of adding solar PV panels to your existing system varies based on system size and panel type. However, the province of Ontario provides incentives and refunds for solar energy installations, which can help offset the initial costs.

Return on Investment

Adding solar PV panels to your existing system will boost your return on investment by lowering your electricity costs and increasing the value of your home.

By adding solar PV panels to your existing solar system in Ontario, you may take advantage of the net-metering program, which allows you to receive credits for any excess energy generated while lowering your electricity costs and carbon impact.

Before deciding, consider your energy requirements, available space, expenses, and ROI.

How to Add Solar Panels to Your Current System?

The following are the steps you can take to add solar panels to your existing system:

Assess Your Energy Requirements

Examine your monthly electricity bills to see how much energy you demand. This will help determine how many panels you must install on your system.

Check the Condition of Your Roof Space

Make sure your roof can withstand the added weight of solar panels. Before continuing, inspect the condition of your roof and repair any damage.

Determine Your System’s Compatibility

Check that the new solar panels will work with your existing system. Ensure that your current system’s voltage and current ratings and the new panels match.

Purchase and Install Solar Panels

Purchase high-quality solar panels from a trustworthy supplier. To ensure accurate installation and wiring, choose a professional installer. There are incentives and rebates available in Ontario for solar energy systems to help offset installation expenses.

Connect the Solar Panels

After installing the panels, connect them to your existing system. A professional installer can perform this for you to ensure a safe and efficient connection.

Regularly monitor your solar system’s performance to ensure it is operating efficiently. The weather in Ontario might impact your system’s output, so monitoring its performance throughout the year is critical.

Adding solar panels to your existing system can be a wise investment with long-term benefits such as lower energy expenses and a lower carbon footprint. Ontario’s average annual solar radiation is approximately 3.8 kWh/m2/day, making it an ideal location for solar power generation.

Following the abovementioned procedures, you can grow your solar energy system and contribute to green and clean energy.

Different Options and Costs for Solar Systems for Your Home

Here are some of the options and costs related to household solar systems:

Grid-Tied Systems

The most prevalent type of solar system in Ontario is a grid-tied system. When the sun shines, they link to the electrical grid and give power to your home. You can get credits on your utility bill by selling any extra energy the system produces back to the grid.

In Ontario, a 5 kW grid-tied system costs between $15,000 and $20,000. There are, however, incentives and rebates available to offset the costs.

Off-Grid Systems

These systems are not connected to the electrical grid and are often used in isolated places with restricted grid access. Batteries are required to store the surplus energy generated by the system.

Cost: A 5 kW off-grid solar system can range in price from $25,000 to $50,000.

Hybrid Systems

Hybrid systems integrate grid-connected and off-grid capabilities. They are grid-connected and can store extra energy in batteries during power shortages.

A 5 kW hybrid solar system in Ontario can cost between $20,000 and $25,000.

It is crucial to note that solar system costs have decreased over time due to technological advances and growing demand. According to market trends, Ontario’s average price of solar systems has reduced by around 60% over the last decade.

Local Laws and Regulations: Upgrading Your Solar Energy System

Here are some crucial points to remember:

Building Permits: Depending on the nature of your solar energy system improvement, you may require a building permit from your local municipality. This could entail adding extra panels or altering the system’s structure.

Electrical Permits: Any electrical work performed on your solar energy system must be performed by a certified electrician and may require an electrical permit from your local electrical safety authority.

Net-Metering Program: The net-metering program in Ontario allows homeowners to receive credits for any extra energy generated by their solar energy system.

However, there are restrictions on how much energy and credits can be generated, and specific standards must be completed to participate in the program.

Utility Regulations: Your local utility company may impose specific regulations or requirements for connecting your solar energy system to the grid. Metering and connectivity standards could be included.

Benefits of Installing Additional Panels for Solar Homeowners

Adding more solar panels can provide multiple benefits for homeowners in Ontario, Canada. These benefits include:

  • Increased energy savings: According to the Ontario Ministry of Energy, solar panels can save the average homeowner up to $1,000 annually on energy expenses. Adding more commissions can reduce reliance on grid electricity, resulting in long-term savings.
  • Reduced carbon footprint: Using solar power helps reduce greenhouse gas emissions, helping Ontario achieve its goal of cutting emissions by 80% by 2050.
  • Increased property value: Homes with solar panels installed have been shown to increase in value by up to 20%, according to the Appraisal Institute of Canada.
  • Lower maintenance costs: Solar panels have a long lifespan and require minimal maintenance, saving homeowners money in the long run.
  • Additional rebates and incentives: The Ontario government offers subsidies and incentives to homeowners who install solar panels, depending on the type and size of the system.

Conclusion: Install Additional Panels to Your Existing System

Adding solar panels or upgrading your current solar panel system to your home can provide cost savings and environmental benefits and potentially increase the value of your home. With government subsidies and incentives available, it’s an affordable and worthwhile investment for homeowners in Ontario, Canada.
