Ground-Mounted vs Rooftop Solar Panels: Pros and Cons

As solar energy adoption continues to grow, homeowners and businesses often face one key decision — whether to install ground-mounted or rooftop solar panels. Both options offer clean, renewable energy and significant long-term savings, but the right choice depends on your space, budget, and energy goals.

In this guide, we’ll explore the pros and cons of ground-mounted and rooftop solar panels to help you decide which system suits your property best.

What Are Rooftop Solar Panels?

Rooftop solar panels are installed directly on the roof of your home or building. They are the most common type of solar installation in residential areas due to their space efficiency and easy integration.

Prons

Space-Saving Solution – Utilizes existing roof space, leaving your yard or open land free for other purposes.

Lower Installation Costs – Typically less expensive than ground-mounted systems due to reduced mounting and wiring requirements.

Government Subsidies – Rooftop systems often qualify for government incentives and subsidies under programs like PM Surya Ghar Yojana in India.

Better for Urban Areas – Ideal for homeowners with limited ground space or small properties.

⚠️ cons

Roof Condition Matters – Installation may not be possible on damaged or shaded roofs.

Difficult Maintenance – Cleaning and servicing panels on a roof can be challenging and sometimes unsafe.

Limited Size – The system size depends on the available roof area and orientation.

What Are Ground-Mounted Solar Panels?

Ground-mounted solar systems are installed on open land or unused ground areas. They are supported by frames or racks that hold the panels at the optimal angle to capture maximum sunlight.

Prons

High Efficiency – Panels can be positioned at the perfect tilt and direction for maximum sunlight exposure.

Easy Maintenance – Easy access for cleaning, inspection, and repairs.

Scalable System – Ideal for larger installations and future expansion.

No Roof Limitations – Perfect for properties with weak, shaded, or unsuitable roofs.

⚠️ cons

Requires Land Space – Not suitable for homes with limited outdoor area.

Higher Installation Costs – Needs additional structures, foundations, and wiring.

Possible Landscaping Impact – Installation may alter the look and layout of your yard or garden.
