As more homeowners and businesses look to reduce energy costs and carbon footprints, solar power has become an increasingly popular option. One of the questions many people ask is whether solar panels on the ground or rooftop solar is the better choice. Both options have advantages and drawbacks, and the best solution often depends on your site, space, and energy needs.
Solar Panels on the Ground
Ground-mounted solar panels are installed on a frame on the ground rather than on a roof. This setup provides flexibility in placement, tilt, and orientation. At Solarvault, our Pitch Perfect Ground Mounted PV System features adjustable panels that can follow the sun throughout the year. This adjustment can generate up to 40% more electricity than static ground-mounted panels, helping to maximise output from the space you have available.
Ground-mounted systems are generally easier to access for maintenance or cleaning, which can make upkeep simpler compared to rooftop installations. They also allow for scalable installations- you can add more panels in the future if you have the space and your energy needs grow. Modern ground-mounted systems like Pitch Perfect are designed to be space-efficient, requiring around 8 metres by 3 metres of clear ground, so even smaller plots can accommodate them.
Planning permission is usually straightforward for ground-mounted panels. In many cases, it isn’t required at all, and where it is, approval is almost always granted. This makes them a practical choice for homeowners who want flexibility and control over panel placement without significant administrative hurdles.
Rooftop Solar
Rooftop solar panels are installed directly on the roof and are often the most convenient choice where space is limited. The main consideration for rooftop solar is the orientation and pitch of the roof – panels work best when they face south and are unobstructed by shading from trees or neighbouring buildings. Some roofs may not be suitable due to size, orientation, or structural limitations, but for suitable roofs, rooftop solar is a compact and unobtrusive solution.
For businesses, Solarvault operates Sunpower Services, offering solar through PPAs (Power Purchase Agreements). With a PPA, businesses can install solar panels at no upfront cost. Solarvault handles installation and maintenance, while the business pays for the electricity generated, often at a lower rate than grid energy. This makes rooftop solar an accessible and financially viable option for businesses, even if roof space is the only available location.
Comparing Ground-Mounted and Rooftop Solar
Ground-mounted and rooftop solar panels both have their place, and neither is universally “better.” Ground-mounted systems offer flexibility, easy access, and scalability, while rooftop panels make use of otherwise unused space and can be ideal where land is limited. Efficiency depends on the orientation and tilt of the panels, whether on a roof or the ground. Adjustable ground-mounted panels like Pitch Perfect can outperform static installations by optimising tilt through the seasons, but well-placed rooftop panels can still provide excellent performance, particularly on south-facing roofs.
Ultimately, the choice comes down to site conditions, energy needs, and budget. Some homeowners prefer the flexibility of ground-mounted solar panels, while others may find rooftop solar more practical or cost-effective. For businesses, rooftop solar with a PPA can remove the upfront cost barrier and deliver immediate savings.
Advanced Technology and Features
The Pitch Perfect Ground Mounted PV System includes high-performance solar panels, angle-adjustable frames, and a Growatt inverter with optional remote monitoring. It comes with a 25-year panel performance warranty and a 2-year product warranty, ensuring long-term reliability. Both standard 400W panels, and larger 585W bifacial panels are available, allowing the system to be tailored to your energy requirements.
Rooftop solar for businesses through Sunpower Services also uses high-quality components, ensuring efficient energy generation and minimal maintenance.
Whether you choose solar panels on the ground or rooftop solar, both are effective ways to harness renewable energy, save on electricity costs, and reduce carbon emissions. Your choice should reflect your space, energy goals, and preferences, and Solarvault can provide expert advice and installation for either option.
