Can Multiple Business Locations Be Planned as One Solar Project?
Yes. A company with several factories, offices, retail branches, warehouses, hotels, schools or other facilities may coordinate them under one corporate solar programme. However, the locations should not automatically be treated as one physical installation or one Solar ATAP application. Each premises may have a separate electricity account, Maximum Demand, roof, connection point, property owner, technical assessment and approval process.
Can Multiple Business Locations Be Combined into One Project?
They can be combined at the corporate planning and procurement level. For example, a company may issue one request for proposal covering ten branches, establish one equipment specification, appoint one preferred provider and negotiate a portfolio-level commercial arrangement.
At the technical and application level, however, each premises may remain a separate project because each site has its own electricity supply, meter, roof, load profile, property rights and connection conditions.
One Corporate Programme
The company may coordinate policy, procurement, financing, implementation and reporting across all locations.
Multiple Site Installations
Each premises may require a separate design, application, meter arrangement, installation schedule and completion process.
One Preferred Provider
A single provider or consortium may be appointed to assess and deliver the portfolio, subject to capability and geographical coverage.
Site-Specific Outcomes
System capacity, savings, approval status, installation cost and project timing may differ between locations.
What Is the Difference Between One Solar Programme and One Installation?
A multi-site solar programme is a corporate implementation strategy. It can include many independent rooftop installations managed under one internal policy or commercial arrangement.
| Item | One Corporate Solar Programme | Individual Site Installation |
|---|---|---|
| Planning | Central objectives, budget, procurement standards and rollout timeline. | Site-specific load, roof, electrical and operational planning. |
| Provider Selection | One tender may be used to appoint a preferred provider. | Provider suitability and local delivery capacity should still be checked for each location. |
| Technical Design | Common design principles and approved equipment list. | Separate layout, capacity, inverter arrangement and connection design. |
| Applications | Centrally coordinated document and submission process. | Separate requirements may apply to each account, meter and premises. |
| Contracting | Master agreement or portfolio commercial framework. | Site schedules, property consents, pricing and responsibilities may be attached separately. |
| Monitoring | Central dashboard and consolidated reporting. | Separate site meters, inverter data and performance records. |
Why Does Each Business Location Need a Separate Assessment?
Two branches belonging to the same company may have very different solar potential. One may operate seven days a week with a large suitable roof, while another may be rented, shaded or closed on weekends.
Each location should normally be assessed for:
- Electricity-account holder
- Tariff or consumer category
- Monthly electricity consumption
- Recorded Maximum Demand
- Interval or half-hourly load data
- Operating days and hours
- Weekend and holiday demand
- Property ownership
- Tenancy and remaining lease period
- Roof-use rights
- Roof dimensions and usable area
- Roof age and remaining life
- Structural capacity
- Shading and surrounding buildings
- Supply voltage
- Meter and connection arrangement
- Switchboard and transformer capacity
- Fire and maintenance access
- Installation restrictions
- Future closure, relocation or expansion plans
How Does Solar ATAP Apply to Multiple Business Locations?
Solar ATAP is a rooftop solar programme for eligible consumers in Peninsular Malaysia. Applications are submitted through the applicable process by an appointed SEDA Malaysia Registered PV Service Provider.
For eligible non-domestic consumers, capacity may be considered up to 100% of Maximum Demand, subject to technical assessment and a maximum installation limit of 1,000kW.
In a multi-location rollout, the relevant Maximum Demand, electricity account, connection point and technical conditions should be confirmed for each premises. The permitted capacity at one location should not automatically be transferred to or combined with another location.
| Solar ATAP Item | Multi-Site Consideration |
|---|---|
| Applicant and Account | Confirm the eligible consumer and electricity-account holder for every location. |
| Maximum Demand | Review the applicable Maximum Demand separately for each non-domestic account. |
| Capacity Limit | Apply the relevant capacity and technical limits to each proposed installation. |
| Metering | Confirm the import and export metering arrangement at each premises. |
| Technical Assessment | Connection voltage, system capacity, distribution network and local conditions may affect each site differently. |
| Submission | A central provider may coordinate the submissions, but each premises may require its own project and account information. |
How Should a Multi-Site Solar Project Be Planned?
Create a Location Register
List every premises, electricity account, property owner, operating entity, address and internal project contact.
Collect Site Data
Gather bills, Maximum Demand, load data, roof photographs, drawings, operating schedules and electrical information for each location.
Screen Technical Suitability
Identify roofs, car parks or approved installation areas that appear structurally, operationally and electrically suitable.
Develop Site Scenarios
Compare conservative self-consumption, larger-capacity and phased options for each viable site.
Rank the Locations
Prioritise locations according to energy demand, roof readiness, ownership, financial value, operational risk and approval complexity.
Select the Commercial Model
Decide whether the portfolio will use direct purchase, financing, leasing, a power purchase agreement or a combination.
Define Common Standards
Establish approved equipment, workmanship, safety, monitoring, reporting, warranty and maintenance requirements.
Implement in Phases
Begin with stronger sites, review actual performance and then refine the next rollout phase.
Which Business Locations Should Be Prioritised First?
The locations with the largest bills are not automatically the best first projects. A strong first-phase site normally combines good daytime demand, suitable property rights, a ready roof and manageable technical conditions.
| Priority Factor | Stronger Candidate | Possible Concern |
|---|---|---|
| Daytime Electricity Demand | Stable weekday and weekend daytime consumption | Low or irregular demand during solar-generating hours |
| Property Control | Owner-occupied property with clear roof rights | Short lease or unresolved landlord approval |
| Roof Condition | Structurally suitable roof with sufficient remaining life | Leakage, corrosion or planned roof replacement |
| Installation Area | Large unshaded roof or suitable car-park area | Shading, skylights, limited access or congested rooftop plant |
| Electrical Readiness | Available connection capacity and updated electrical records | Unknown switchboard condition or complex connection work |
| Business Continuity | Long-term location with stable operations | Possible closure, relocation or redevelopment |
| Internal Approval | Clear budget owner and decision-making process | Multiple unresolved stakeholders |
| Project Replicability | Site type repeated across many branches | Highly customised premises with limited portfolio relevance |
What Procurement and Contract Models Can Be Used?
A multi-site project can use centralised procurement while preserving site-specific technical and legal schedules.
| Procurement Model | How It Works | Main Considerations |
|---|---|---|
| One Provider for All Sites | One provider assesses, designs and delivers the complete portfolio. | Geographic coverage, delivery resources, local subcontractors, consistency and concentration risk. |
| Regional Provider Model | Different providers are appointed for different states or regions. | Common standards, reporting consistency, warranty administration and internal coordination. |
| Panel of Approved Providers | Several providers are prequalified and locations are allocated according to capability or pricing. | Clear allocation rules, comparable quotations and avoidance of inconsistent specifications. |
| Master Agreement with Site Schedules | Common legal terms apply across the portfolio while each site has its own scope and commercial schedule. | Site acceptance, delays, property consents, pricing and liability should be clearly separated. |
| Separate Site Contracts | Each location signs an independent project contract. | Greater flexibility but potentially more administration and inconsistent terms. |
| Portfolio PPA or Lease Framework | A long-term commercial framework covers several independently installed systems. | Site-specific energy rates, minimum purchase, roof rights, termination and transfer provisions. |
How Should Multi-Site Financial Results Be Compared?
Portfolio totals can support management decisions, but each location should also have a separate financial model. A profitable site should not unintentionally hide a weak or unsuitable site.
Each site comparison should include:
- Proposed capacity in kWp
- Total installed project cost
- Cost per kWp
- Estimated annual generation
- Estimated self-consumption percentage
- Estimated surplus generation
- Applicable electricity-tariff assumptions
- Maximum Demand assumptions
- Estimated annual electricity-cost reduction
- Operations and maintenance cost
- Roof or electrical upgrade cost
- Financing cost
- Estimated payback period
- Internal rate of return where required
- Contract duration
- Tariff or lease escalation
- Equipment-replacement assumptions
- Roof-removal and reinstatement obligations
Site-Level Business Case
Shows whether each location is technically suitable and financially justified on its own assumptions.
Portfolio-Level Business Case
Combines capital requirement, expected generation, savings, implementation timing and sustainability reporting.
Weighted Portfolio Results
Prevents a simple average from overstating performance when sites have significantly different sizes.
Sensitivity Analysis
Tests lower generation, tariff changes, project delays, financing costs and branch closure scenarios.
How Should Multiple Solar Locations Be Monitored?
A central monitoring platform can help the company compare site performance, identify faults and prepare consolidated energy reports. However, the company should retain access to individual site data.
- Site-level generation data
- Portfolio-level generation total
- Inverter status and alarms
- Daily and monthly performance trends
- Expected versus actual generation
- Site-level self-consumption where measured
- Surplus electricity where measured
- System downtime
- Maintenance records
- Cleaning records
- Warranty claims
- Fault-response times
- Data-export capability
- User-access permissions
- Cybersecurity and account management
- Long-term data retention

Frequently Asked Questions
Can multiple business locations be planned as one solar project?
Yes. They may be coordinated under one corporate procurement and implementation programme, but each location may still require a separate assessment, design, application, meter arrangement and installation.
Can one Solar ATAP application cover all business branches?
A business should not assume that one submission covers separately metered premises. The provider should confirm the applicable submission requirements for each electricity account and connection point.
Can excess solar from one branch offset another branch?
This should not be assumed under a standard rooftop self-consumption arrangement. Cross-site offset or aggregation requires an applicable framework that expressly permits it.
Can one solar provider handle every location?
Yes, provided the provider has suitable technical capability, geographical coverage, project-management resources and regional maintenance support.
Should every branch install the same solar capacity?
Not necessarily. Each site has different electricity demand, Maximum Demand, roof space, operating hours and technical conditions, so the appropriate capacity may differ.
Can a business negotiate a portfolio discount?
A provider may offer volume pricing, but the business should still check site-specific costs such as structural work, electrical upgrades, technical studies, difficult access and regional mobilisation.
Should all locations be installed at the same time?
Not always. A phased rollout can begin with technically ready and financially stronger sites before conditional or more complex locations.
Can rented branches be included?
Yes, but landlord approval, roof rights, remaining lease duration, equipment ownership and end-of-lease responsibilities should be confirmed for each rented site.
Can all sites use one monitoring dashboard?
Potentially yes, if the selected equipment and monitoring systems are compatible. The business should retain access to both consolidated and site-level data.
Does Solar100 manage the final multi-site engineering design?
No. Solar100 supports provider discovery and quotation comparison. The selected provider and appointed professionals remain responsible for assessments, engineering, applications, approvals, installation and maintenance.
