Solar100 can help Malaysian homeowners and businesses discover participating solar providers and compare multiple quotations based on system capacity, equipment, generation estimates, warranties, project scope, payment terms and total price.
Can Solar100 Help Me Compare Multiple Solar Quotations?
Solar100 helps homeowners and businesses discover participating solar providers and understand how to compare the quotations they receive using more consistent technical, commercial and service-related criteria.
How Can Solar100 Help With Quotation Comparison?
Solar100 provides a solar-focused starting point for users who want to discover providers and compare proposals without relying only on the lowest advertised price.
Discover Providers
Find participating solar companies based on location, property type and project requirements.
Request Quotations
Submit basic project details and request consultations or proposals from relevant providers.
Compare Consistently
Review systems using similar categories such as capacity, equipment, warranties and complete project cost.
Review Verification
Check available Solar100 Verification information for participating providers.
Ask Better Questions
Understand what should be clarified before accepting a proposal or making payment.
Make Your Own Decision
Select a provider only after reviewing the complete technical, financial and contractual proposal.
Will Solar100 Always Provide Multiple Solar Quotations?
Solar100 may help users connect with one or more participating solar providers, depending on:
- Property or facility location
- Residential or commercial project type
- Required solar service
- Estimated project size
- Roof or property conditions
- Provider service areas
- Provider capabilities
- Current provider availability
The number of available companies may vary between locations and project categories. Solar100 cannot guarantee that every enquiry will receive a fixed number of quotations.
How Does the Solar Quotation Comparison Process Work?
- Submit Project Details Provide your location, electricity usage, property type, roof details and preferred project timeline.
- Receive Provider Contact Participating providers may request electricity bills, photographs or arrange a consultation.
- Collect Written Proposals Request complete written quotations with equipment, warranties, installation scope and exclusions.
- Compare and Clarify Compare the proposals side by side and ask providers to explain any unclear or missing information.
Users should avoid comparing a preliminary estimate from one provider with a complete technical quotation from another. The documents should cover a similar level of project detail.
Why Should I Give Every Provider the Same Information?
A fair comparison requires each provider to base its recommendation on similar property and electricity information.
Where possible, provide each company with the same:
- Recent electricity bills
- Electricity consumption history
- Property address
- Property and roof type
- Roof photographs
- Daytime usage information
- Future electricity plans
- Preferred installation timeline
- Battery requirements, where relevant
- Financing or payment preferences
What Should I Compare Between Solar Quotations?
A useful comparison should cover both the technical system and the complete commercial arrangement.
System Design
Compare the proposed capacity, panel quantity, layout, inverter type and estimated annual generation.
Equipment
Review the exact solar panel, inverter, mounting and monitoring equipment models included.
Installation Scope
Confirm roof mounting, wiring, electrical work, waterproofing, access, testing and commissioning.
Applications
Check which applications, documents, submissions, responsibilities and related fees are included.
Warranty and Support
Compare product, performance, inverter, workmanship and after-sales support terms.
Price and Payment
Review the total project cost, deposit, progress payments, exclusions and optional charges.
| Comparison Area | What to Check | Why It Matters |
|---|---|---|
| System Capacity | Proposed capacity in kWp and the reason for the recommendation | Affects equipment quantity, generation and project price |
| Generation Estimate | Estimated annual output and calculation assumptions | Helps evaluate whether projections are realistic and comparable |
| Solar Panels | Brand, model, wattage, quantity and warranty | Different products may have different specifications and support |
| Inverter | Brand, model, capacity, system type and monitoring | The inverter affects system operation, monitoring and maintenance |
| Installation Scope | Mounting, wiring, electrical work, access and safety provisions | Missing work may lead to additional charges later |
| Applications | Included submissions, documentation and fees | Clarifies which party is responsible for administrative work |
| Warranty | Product, performance, inverter and workmanship terms | Determines the available protection after installation |
| O&M Support | Monitoring, inspection, maintenance and response time | Important for long-term system operation and issue resolution |
| Project Timeline | Assessment, design, approval, installation and commissioning stages | Helps identify unrealistic or incomplete schedules |
| Total Price | Complete price, payment terms, optional costs and exclusions | Supports a like-for-like financial comparison |
How Should I Compare System Capacity and Generation Estimates?
Different providers may recommend different system capacities even when reviewing the same property.
Ask each provider to explain:
- Why the proposed system capacity was selected
- Which electricity bills were used
- How daytime electricity usage was considered
- How available roof space was calculated
- Whether shading was included
- What annual generation is estimated
- Which performance assumptions were used
- Whether system losses were considered
- Whether future electricity usage was considered
- Whether the proposal includes a battery
How Should I Compare Solar Panels and Inverters?
Quotations should state the exact equipment included rather than using general descriptions such as “premium panel” or “high-quality inverter.”
For solar panels, compare:
- Manufacturer and exact model
- Panel wattage
- Number of panels
- Module efficiency
- Product warranty
- Performance warranty
- Local warranty support
- Replacement availability
For inverters, compare:
- Manufacturer and exact model
- Inverter capacity
- String, hybrid or microinverter design
- Monitoring platform
- Warranty period
- Warranty extension options
- Local technical support
- Replacement process
How Do I Compare Installation Scope and Exclusions?
A lower-priced quotation may exclude work that another provider has included. This can make the cheaper proposal appear more attractive than it really is.
Check whether the quotation includes:
- Solar panel mounting system
- Roof penetration and waterproofing work
- DC and AC cabling
- Electrical protection equipment
- Distribution board work
- Inverter installation
- Monitoring setup
- Access equipment
- Safety equipment
- Testing and commissioning
- Application and documentation work
- Site cleaning after installation
Common exclusions may include:
- Roof repair
- Roof strengthening
- Structural engineering assessment
- Electrical system upgrades
- Additional cable routes
- Special access equipment
- Internet or communication devices
- Maintenance packages
How Should I Compare Solar Warranties and O&M Support?
A solar proposal may contain several different warranties. They should not be treated as one single guarantee.
| Warranty or Support Area | What to Confirm |
|---|---|
| Panel Product Warranty | Duration, covered defects, claim procedure and responsible party |
| Panel Performance Warranty | Performance terms, degradation assumptions and claim conditions |
| Inverter Warranty | Standard term, extension options, labour and replacement coverage |
| Workmanship Warranty | Installation defects, roof-related work and service response process |
| Mounting Warranty | Coverage for mounting components and installation-related issues |
| Monitoring Support | Setup, system alerts, data access and troubleshooting assistance |
| O&M Support | Inspection, cleaning, preventive maintenance and response time |
| Warranty Claims | Who coordinates the claim and whether labour or transport is included |
Ask whether the installer will continue assisting with warranty claims after the installation has been completed.
Should I Choose the Cheapest Solar Quotation?
Not necessarily. A lower quotation may use a smaller system, different equipment, shorter warranties or a more limited installation scope.
Before comparing prices, confirm that each quotation covers:
- A similar system capacity
- Comparable equipment specifications
- The same property or roof areas
- Similar application services
- Equivalent installation work
- Comparable warranty coverage
- Similar monitoring and maintenance support
- All required taxes and fees
- Clear payment terms
- All excluded items
