Read how to optimise space for commercial solar panels, maximise energy output, and plan for long-term efficiency and cost savings
Understanding the space requirements for commercial solar panels is crucial for businesses in Manchester, Greater Manchester, and the North West looking to harness solar energy generated from clean energy sources. Before installing solar panels, it’s essential to consider the available space to ensure optimal efficiency and cost-effectiveness. Space requirements directly impact the efficiency of a solar installation, as insufficient space can lead to shading and reduced energy generation. The initial steps in planning a solar panel installation include assessing the available space, understanding energy needs, and consulting with solar experts.
Understanding Solar Panel Requirements
Commercial solar panels typically require a significant amount of space to generate the desired amount of solar energy. This is one of the factors that reduces the payback periods. Several factors influence the space needed for solar panel installations, including the type of panels used, the efficiency of the solar cells, and the overall energy generation goals. For instance, high-efficiency panels may require less space compared to standard panels. On average, commercial solar installations require about 100 square feet per kilowatt of solar power. For example, a 100 kW system would need approximately 10,000 square feet of space (shadow free for optimum generation). Different types of solar panels, such as monocrystalline, polycrystalline, and thin-film, have varying space requirements. We prefer to use monocrystalline panels, known for their high efficiency, typically require less space compared to polycrystalline and thin-film panels.
Factors Influencing Solar Installation Space
The efficiency of solar panels plays a significant role in determining the space requirements for a solar installation. High-efficiency panels can generate more power in a smaller area, making them ideal for limited spaces. The installation method also affects space needs. On-roof mounted panels require less ground space but must be installed on a structurally sound roof. In-roof mounted panels integrate with the roof structure, offering a sleek appearance but may require more space. Ground-mounted panels, while requiring more land, offer flexibility in orientation and tilt, maximising solar energy collection. Shading and orientation are critical factors; even partial shading can significantly reduce energy output. Local regulations and building codes also impact the installation layout, dictating setbacks, height restrictions, and other considerations.
Optimising Your Available Space
Accurately assessing the available space for solar installation is the first step in optimising panel placement. Techniques such as using high-efficiency panels, installing panels at optimal angles, and utilising tracking systems can maximise output in limited spaces. Solarus will conduct a satellite survey as well as a thorough site survey to evaluate your area, and our software will assess the space available, whilst taking into consideration all shading. On shaded buildings or pieces of land, our proposal may also include optimised string or micro inverters. This means that if one panel is more shaded than another, the performance of the entire solar PV array won’t dip.
For businesses in Stockport and around Greater Manchester, considering future expansion is crucial. Planning for additional panels or battery storage can ensure that the solar installation meets growing energy needs. High-efficiency panels are particularly beneficial in restricted areas, as they generate more power per square foot. Additionally, innovative solutions like vertical solar panels or solar canopies over carparks can help businesses make the most of their available space. Floating installations are a great way to utilise a huge space, floating on reservoirs for example, and even the use of bi-facial panels to make use of the solar generation on reflections.
Case Studies and Examples
Several successful commercial solar installations demonstrate the effective use of space. For instance, a manufacturing plant in the North West optimised its available roof space by installing high-efficiency monocrystalline panels, resulting in significant energy savings and reduced electricity costs. Another example is a retail outlet in Greater Manchester that utilised a combination of roof-mounted and ground-mounted panels to maximise solar energy generation. These case studies highlight the importance of thorough planning and innovative solutions in optimising space for solar installations. Lessons learned from these projects include the value of conducting detailed site assessments, considering future energy needs (future proofing designs), and adhering to local regulations.
Assessing and Planning for Optimal Solar Panel Space
Carefully assessing and planning the space for commercial solar panel installations is essential for maximising efficiency and achieving long-term energy savings. By understanding the space requirements and considering factors such as panel efficiency, shading, and local regulations, businesses can ensure a successful solar installation that meets their energy needs.
