When considering solar panels, one of the first questions to answer is: Is my home suitable for solar panels? The benefits of going solar (like lower power bills) are clear, but your home’s solar potential depends on specific factors.
Here’s how you can determine if solar is right for you, with a focus on Nova Scotia’s climate and conditions.
Roof Condition and Structure
Assessing your roof’s condition is important. Your roof should be in good shape since panels are expected to last 25 years or more. Here’s what to consider:
- Age of the Roof: A newer roof is ideal for solar installation. If your roof is close to 15–20 years old, you may need to replace it before installing panels to avoid the expense of removing and reinstalling them in a few years.
- Roof Material: While most roofs can support solar panels, certain materials (like asphalt shingles, metal, and concrete tiles) are easier to install than others. Solar Ascent can evaluate whether your roof structure can bear the additional weight of panels.
- Pitch and Orientation: In Nova Scotia, a south-facing roof with a pitch between 20 and 40 degrees typically maximizes solar energy production. East- or west-facing roofs can also work.
Shading and Sunlight Exposure
To take advantage of the sun’s rays, your roof should receive ample direct sunlight throughout the day. That’s because shading can reduce solar output.
- Tree Coverage: Nearby trees (full-foliage ones in summer) or structures that cast shade on your roof can significantly affect panel efficiency. While some shading can be managed with newer panel technology, heavily shaded roofs may struggle to generate enough energy.
- Building Shadows: Tall neighbouring buildings can also create shade, particularly in downtown Halifax, Bedford, Clayton Park West, etc. Solar Ascent can access data on shading patterns to understand how much sun your roof receives daily.
Location and Nova Scotia's Climate
Nova Scotia’s climate and location affect how well solar panels perform.
- Seasonal Changes: With long winters and varying amounts of daylight, Nova Scotia’s climate means solar production will peak in the summer and reduce in winter. Solar panels are still effective even in colder months, but snow accumulation and fewer daylight hours can impact production. Our systems are designed to shed snow naturally.
- Latitude and Solar Intensity: Nova Scotia’s location means it has slightly less solar intensity than southern regions. Despite this, you can save on your Nova Scotia Power bills, especially with the province’s high electricity rates. Solar systems here are designed to perform well even on cloudy days, and technological advances mean they can capture and use indirect sunlight.
Energy Consumption
Evaluating your home’s energy needs and the financial factors can help clarify if solar is a wise investment.
- Electricity Usage: The more energy you use, the more likely solar will be cost-effective. Review past electric bills to see your average consumption. Nova Scotia Power’s MyEnergy Insights is a digital tool that details your approximate energy usage. Solar Ascent will use this data to recommend a system size that meets your needs.
