The demand for eco-friendly energy is no longer just a trend for landed houses; it is now extending to vertical residential buildings.
Installing rooftop solar power systems (PLTS) in apartment complexes is an effective strategy to reduce building operational costs while supporting environmental sustainability.
Although implementing solar power in high-rise buildings presents unique challenges, the resulting energy efficiency has proven to add investment value for both developers and residents.
Why Do Apartments Need Rooftop Solar Power Systems?
Apartment building management requires a continuous, 24-hour electricity supply. A significant portion of this energy consumption is allocated to public or common areas.
1. Reducing Electricity Costs for Common Facilities
Using solar power systems or panels can help lower daily electricity bills for specific areas, such as:
Lighting for corridors, lobbies, and parking areas. Water pumps and swimming pool filtration systems. Elevator operations and air conditioning in common facilities.
2. Reducing the Building's Carbon Footprint
Solar power systems do not produce greenhouse gas emissions during operation.
Consistent use of solar energy helps significantly lower the building's carbon emission levels.
3. Increasing Resale Value and Competitiveness
Properties that adopt green building concepts command higher resale values and greater rental appeal.
Modern, environmentally conscious residents increasingly prioritize homes that implement eco-friendly principles.
Solar Power Operational Schemes in Apartments
Solar energy implementation in high-rise buildings generally falls into two approaches:
1. Solar Power for Public Areas (Common Areas)
At this scale, solar panels are installed on the rooftop or in parking areas (carports).
The generated electricity is fed directly into the building management's internal grid to support the operational loads of shared facilities.
2. Micro-Solar PV for Individual Units
This model channels energy from individual solar panels or a shared capacity system directly to the meters of specific units.
This model requires technical coordination and approval from the apartment management body regarding the allocation of power capacity.
Examples of Apartment Solar PV Implementation in Indonesia
Several property developers in Indonesia have implemented rooftop solar PV systems in their vertical residential projects.
A concrete example of solar energy implementation in vertical housing is the Bandara City Apartment project in Tangerang, developed by Provident Development. The developer installed solar panel facilities within the apartment complex to support energy efficiency and provide modern, eco-friendly residential facilities.

Beyond purely vertical residential sectors, the integration of rooftop solar PV technology is also widely adopted in mixed-use developments and modern residential complexes, such as the NavaPark BSD area.
Challenges and Solutions for Solar PV Installation in Vertical Buildings
Installing solar panels on apartments requires specialized technical analysis compared to standard houses.
1. Limited Rooftop Area
Apartment rooftop space is limited when compared to the total gross floor area.
Solution: Use high-efficiency solar panel modules (such as Monocrystalline types) or integrate Building-Integrated Photovoltaics (BIPV) systems into the building's exterior walls.
2. Shading Effect
Shadows cast by taller surrounding structures can reduce solar energy absorption.
Solution: Conduct shading simulations prior to installation and utilize power optimizer or microinverter technologies.
