As cities grow, the demand for clean, renewable energy sources is greater than ever. Urban dwellers are increasingly looking for ways to integrate sustainable solutions into their daily lives. However, with limited space and dense populations, how can solar energy be effectively adopted? What is the future of solar energy in big cities?
Innovations like solar windows, building-integrated photovoltaics (BIPVs), and shared solar spaces are paving the way for a future where cities capture solar energy and harness its power efficiently. In this post, we’ll explore the future of solar energy and how it can transform city living.
Understanding the Role of Solar Energy in Urban Areas
Traditional solar panels are often associated with suburban homes with much more rooftop space than condos or apartment buildings in large cities. However, urban residents are embracing sustainability and finding ways to overcome challenges like limited space, shading from tall buildings, and zoning restrictions.
New advancements like building-integrated photovoltaics and community solar projects are making solar energy more accessible, even in densely populated areas. By integrating solar technology, cities can lower energy costs, reduce their carbon footprint, and enhance energy resilience, paving the way for a cleaner, more sustainable future.
Innovative Urban Solar Solutions
Despite the limited space in many cities, solar panels can be installed in innovative ways. Here are some top solar energy industry trends and a look at the future of solar energy in urban areas.
Rooftop Solar Installations
A common way urban dwellers adopt solar energy is through rooftop solar panels. Many Canadian cities, including Toronto and Vancouver, have incentivized property owners to install rooftop solar panels.
These systems allow residents to generate their electricity, reduce energy bills, and even sell excess power back to the grid. For example, Vancouver residents can save up to $10,000 on eligible solar panels and battery storage with BC Hydro.
Other emerging trends, such as solar shingles and lightweight, flexible solar panels, make it easier for buildings with structural limitations to adopt solar power without compromising aesthetics or integrity.
Building-Integrated Photovoltaics
Building-integrated photovoltaics (BIPVs) are revolutionizing how solar panels are incorporated into cities. Unlike traditional solar panels added onto existing structures, BIPVs are integrated into building materials, such as windows, facades, and roofs. They serve a dual purpose by not only converting solar energy into electricity, but also providing additional aesthetics and function to the building, like thermal insulation, weather protection, and daylight illumination.
In Toronto, Canadian BIPV manufacturer Mitrex is installing Ontario’s largest building-integrated PV wall, spanning over 7,000 square feet of customized solar facade panels. Capable of generating 100 kW of energy, this system is expected to produce 90,000 kWh annually, significantly reducing the building’s carbon footprint.

Solar Windows
Solar window technology is an exciting advancement in the future of solar energy. These transparent solar panels can be installed in high-rise buildings, allowing entire skyscrapers to generate renewable energy. Companies like SolarWindow Technologies and Ubiquitous Energy have developed window coatings that convert sunlight into electricity, offering an efficient solution that saves space and sustainably generates power.
If widely adopted, solar windows could provide a significant portion of a city’s energy demand, reducing reliance on fossil fuels and enhancing urban sustainability. Solar windows and other transparent solar panel technologies could provide about 40% of energy demand in North America.
Shared Solar Spaces and Community Solar Projects
Not all city residents have access to a personal rooftop to install solar panels. The solution to this is shared solar spaces and community solar projects. These programs allow multiple households and businesses to invest in the city’s development and benefit from a single solar energy system.
A recent example of this initiative is Canada’s first subscription-based community solar program in Cape Breton, Nova Scotia. This program provides affordable, renewable electricity to residents who can’t install their own solar panels and gives them the option to buy solar power from the community.
SolarShare is another company that makes renewable energy accessible through community projects across Canada. It has over 2,000 members and allows residents and businesses to invest directly in solar projects.

Solar Powered Transportation Solutions
Solar-powered transportation is becoming increasingly popular. It’s revolutionizing urban transportation systems by offering sustainable, energy-efficient alternatives to traditional fuel-dependent vehicles. Cities are adopting electric buses, trains, and trams equipped with solar panels that recharge their batteries, reducing reliance on the grid.
In Alberta, the City of Grande Prairie introduced electric buses powered by 480 solar PV panels. The clean energy generated from these panels is sent to the battery, and any surplus energy goes to the electrical grid. Not only does this power the vehicle but also helps residents offset the electricity costs.
Additionally, solar-powered charging stations for electric vehicles are becoming more common in cities, providing a convenient, eco-friendly way for EV owners to charge their vehicles while reducing the city’s energy consumption.
Overcoming Urban Solar Challenges
Since space is limited in cities, adopting solar energy can be challenging. However, there are several ways urban areas can maximize their solar potential.
Space Constraints and Shading
Urban areas present unique challenges for solar installation due to large buildings and limited open spaces. However, solutions like vertical solar farms, solar canopies over parking lots, and integrating panels into public transit infrastructure (e.g., solar-powered bus stops) are helping cities maximize solar energy use.
For instance, companies like VCT Group are installing solar carports and canopies, turning parking spaces into dual-use environments, creating shade for residents and generating power for cities simultaneously.
Policy and Incentives
Government financial incentives and policies play a large role in the future of solar energy. Programs like Canada’s Greener Homes Initiative provide financial support for residential solar installations, while municipal programs are helping businesses adopt solar technologies.
For example, Hydro Quebec has a net metering initiative for customers who generate electricity from a renewable energy source. This initiative allows them to transfer surplus power into the grid in exchange for kWh applied to their bill. In addition, financial tax credits and grants incentivize homeowners, businesses, and developers to integrate solar power into metropolitan environments.
Technological Advancements
Recent advancements in solar panel technology, including more efficient photovoltaic cells, flexible solar panels, and improved energy storage systems, make urban solar more accessible. Developments in smart grids and battery storage enable residents to store excess energy for use during peak hours, increasing the reliability of solar power.
Innovations, such as perovskite solar cells and bifacial panels, can increase efficiency while lowering the cost of solar energy, further improving accessibility for urban populations.
