Preparing Your Home for Solar Installation: What You Need to Know


As the demand for sustainable energy solutions that reduce monthly energy costs continues to grow, more Ontario homeowners than ever are considering the switch to solar power. Installing solar panels can significantly reduce your carbon footprint and save you money in the long run.

Plus, there have never been more rebates, grants and tax incentives to help with the cost (which is lower than ever). However, before you embark on this eco-friendly, cost-saving journey, it’s important to prepare your home for solar installation properly.


This guide walks you through the essential steps and tips to ensure a smooth transition to solar energy.

Before installing solar panels, it’s crucial to understand your current energy consumption. Consider hiring a professional to conduct a home energy audit. This assessment will help you identify areas where you can improve energy efficiency, potentially reducing the number of solar panels needed to meet your energy needs.

Solar panels are typically installed on rooftops, so it’s essential to ensure that your roof is in good condition. Check for any signs of damage, such as leaks, loose shingles, or structural issues. If your roof requires repairs or replacement, addressing these issues before the solar installation is best.

The orientation of your roof plays a crucial role in the efficiency of your solar panels – and the solar professionals at Otter Energy use the most up-to-date design tools and technology to plan and optimize your installation. Ideally, your roof should face south to maximize sun exposure – but with modern solar panels, any home can benefit from the sun’s free energy! You may also want to consider any potential sources of shading, such as nearby trees or buildings. Trimming or removing obstructive objects can help optimize solar panel performance.

Before installation, Otter Energy will work with you to obtain all necessary permits and approvals from local authorities. We’ve installed over 300,000 solar panels, so the Otter is very well-versed in the permitting process and can assist you in acquiring the required documentation.

Ensure the area around your home is clear and accessible for the installation team. Remove any obstacles or debris that may hinder their work. This includes trimming back overgrown vegetation and ensuring there are no obstructions on the roof itself.

Depending on the age and condition of your home’s electrical system, you may need to make upgrades to accommodate the solar panels. This could involve adding a new electrical panel or upgrading existing wiring to handle the additional load.

Solar panels are typically attached to the roof using mounting brackets that require penetrations. It’s important to discuss this with your installer to ensure that the penetrations are done correctly and won’t compromise the integrity of your roof. The Otter has years of design and engineering experience to ensure your panels perform flawlessly and look great doing what they do!

Solar panels are very low-maintenance. But it’s essential to have a plan in place for routine cleaning and inspections. Dust, dirt, and debris can accumulate on the panels over time, potentially reducing efficiency. Regular maintenance will help ensure your solar system continues to operate at peak performance.

Preparing your Ontario home for solar installation is a crucial step toward harnessing the power of renewable energy. By conducting a thorough assessment, addressing any necessary repairs, and working closely with a reputable solar installation company like Otter Energy, you’ll be well on your way to enjoying the benefits of clean, stable and sustainable energy. Remember, a well-prepared home sets the foundation for a successful solar journey.
