Solar Panels to Enhance Parking Lots and Shopping Mall Rooftops

Hydro-Québec is focusing on solar energy to increase its electricity production in the coming decades. The state-owned company aims to utilize parking lots and shopping mall rooftops as prime spots for solar panel installation. By 2035, Hydro-Québec plans to boost its energy production by 11,000 megawatts (MW), which is a 50% increase from the current consumption levels of its clients in the Montreal area.
Objectives for Solar Energy Production
Hydro-Québec has set an ambitious goal of generating 3,000 MW from solar energy within this timeline. To initiate this process, the company launched a tender last year for private projects totaling 300 MW. This tender is set to conclude at the end of the month.
- Total Increase in Production: 11,000 MW by 2035.
- Target for Solar Energy: 3,000 MW from solar sources.
- Current Tender: 300 MW for private projects.
According to Jonathan Côté, a spokesperson for Hydro-Québec, the initial tender will provide valuable market insights to determine the most cost-effective ways to reach the solar energy target. The company is particularly interested in photovoltaic plants that are small to medium-sized, with capacities of up to 25 MW, connected to low and medium voltage systems, and operational no later than 2029.
Installation Guidelines and Strategies
The tender outlines specific guidelines for solar panel installations. Hydro-Québec expresses a clear intention to prioritize locations that minimize the need for new land. This includes installations on pre-existing artificial surfaces, such as parking lots or building rooftops.
Producing electricity closer to consumption sites greatly benefits the transportation network, alleviating pressure on critical components of the grid. Hydro-Québec emphasizes deploying solar energy responsibly to help keep costs low.
Cost Considerations
Hydro-Québec is keen to assess market costs through the results of the tender. The overall costs of solar energy have significantly decreased recently, and projections indicate this trend will continue. The company intends to adopt a blend of energy solutions, including efficiency measures, wind power, and solar energy, to achieve optimal cost outcomes.
Innovative Solar Projects
Simons, a retail company, has been proactive with solar energy by installing solar panels on its rooftop and in the parking area at the Galeries de la Capitale since 2018. This project aimed to make the store energy self-sufficient rather than supplying energy back to the Hydro-Québec grid.
- Number of Solar Panels: 3,328 bifacial solar panels.
- Year of Installation: 2018.
- Location: Galeries de la Capitale, Quebec.
The project is notable for using bifacial panels, which are capable of capturing sunlight from both sides, potentially utilizing reflected light and enhancing energy production.
International Trends in Solar Panel Installations
Internationally, similar trends are emerging. France has mandated that all parking lots larger than 1,500 square meters must feature solar panels covering at least half their area. Such regulatory frameworks promote the integration of solar energy into existing structures.
Additionally, in Germany, a transparent solar canopy has been installed on an expressway leading to Munich Airport. This installation, which covers four lanes, can generate enough energy to power 70 homes.
Support for Domestic Solar Projects
To encourage solar energy adoption, Hydro-Québec has introduced a subsidy program for solar panel installations at homes. This offers $1,000 per installed kilowatt, up to a maximum of 40% of the total cost.
- Subsidy Amount: $1,000 per kilowatt installed.
- Maximum Limit: 40% of total installation cost.
The initiative can translate into significant assistance, potentially providing up to $5,000 for an average home and $40,500 for commercial buildings.
As Hydro-Québec and other entities explore solar energy solutions, the potential for innovation and sustainability in urban landscapes continues to grow, leading to a cleaner energy future.
