Pros and Cons of Solar PV
With rising electricity costs and increasing environmental awareness, many homeowners in Alberta are considering rooftop solar photovoltaic (PV) systems. While solar energy offers several benefits, it also comes with some challenges. This article explores the pros and cons of installing rooftop solar PV in Alberta to help you make an informed decision.
The Pros…
1. Reduced Electricity Bills
Alberta's net billing program allows homeowners to sell excess electricity back to the grid, reducing electricity costs. Solar panels can significantly lower your utility bills, making them a financially attractive option. Preferred utility rates are an added bonus when enrolling in a Solar Club, allowing you to save even more.
2. Environmental Benefits
Solar energy is a renewable and clean source of power, reducing reliance on fossil fuels. By switching to solar, homeowners can decrease their carbon footprint and contribute to a greener future and healthier communities.
3. Energy Independence
With solar panels, you generate your own electricity, reducing dependence on utility providers. Solar can also be a great power source in areas where a power grid in unavailable.
4. Government Incentives
Although Alberta does not currently have a province-wide rebate program, federal incentives such as the Canada Greener Homes Grant (Up to $40,000, interest-free, 10 yr payback period) can help offset installation costs. Additionally, municipal programs like the Edmonton Solar Rebate provide further financial assistance. Visit solaralberta.ca to see what additional incentives may be available in your area.
5. Increased Home Value
Homes with solar installations are often more attractive to buyers. A properly installed solar PV system can increase property value and make a home more marketable. Homes with solar sell for an average 4.8% higher than those without providing a positive return on your investment.
The Cons..
1. High Upfront Costs
The initial investment for a solar PV system, including panels, inverters, and installation, can be high. Although costs have decreased in recent years, homeowners still need to consider whether the choice to install solar is right for them. Government funding such as the Canadian Greener Homes loan has made solar more attainable for most.
2. Weather Dependence
Alberta has long, sunny summers, but winter conditions can impact solar energy production. Snow accumulation on panels and shorter daylight hours mean reduced energy generation during winter months. Rain and air pollutions, like smoke from forest fires, can also have an impact on panel production. When sizing a solar system for your energy needs, seasonal conditions—like snowy winters—are taken into account to help maximize your annual energy offset.
3. Roof Suitability
Not all roofs are ideal for solar panels. Factors such as shading, roof orientation, and obstructions must be evaluated. Installation costs may also vary by roof type and installation difficulty. For example, metal and shingle roofs are usually great for solar, however it can be more difficult to install panels on a clay tile roof.
4. Location Limitations
Although most locations and building types can be fitted with a solar PV system, there are limitations for inner city dwellings. Calgary has a central area where solar cannot be installed due to city regulations. Installing solar on apartment buildings may also provide significant challenges unless the building is built solar-ready.
Conclusion
Rooftop solar PV systems offer Alberta homeowners a way to lower electricity bills, reduce environmental impact, and increase energy independence. However, the initial costs and other limitations should be carefully considered before making a decision. By evaluating your energy needs, financial situation, and roof suitability, you can determine whether solar is the right choice for your home.
