Before requesting a solar quotation in Malaysia, prepare recent electricity bills, property details, roof information, photographs, location and your preferred installation timeline. Commercial projects may require additional electrical, structural and business information.
What Information Should I Prepare Before Requesting a Solar Quote?
Preparing complete and accurate information helps solar providers understand your property, electricity usage and project objectives before recommending a system or preparing a quotation.
Quick Solar Quotation Checklist
The amount of information required depends on whether the project is for a home, commercial property, factory or other facility. However, most enquiries begin with the following six areas.
Location
Provide the full property address, city, state and postcode.
Electricity Bills
Prepare recent bills showing usage, charges and account information.
Property Type
State whether the property is a house, factory, warehouse or office.
Roof Details
Share the roof type, approximate area, condition and available space.
Photographs
Include clear photos of the roof, electrical area and surrounding site.
Project Goals
Explain your preferred timeline, budget and main solar objectives.
What Electricity Bill Information Should I Prepare?
Electricity information is one of the most important parts of a solar quotation request. It helps the provider estimate your consumption, daytime usage and possible system capacity.
Prepare the following where available:
- Recent monthly electricity bills
- Electricity account holder’s name
- Property or account address
- Monthly electricity consumption
- Monthly electricity charges
- Tariff category shown on the bill
- Maximum demand information for businesses
- Consumption history over several months
- Information on unusual seasonal usage
- Existing solar export or billing information
Providing several recent bills may give the provider a better understanding of your normal consumption than providing only one month.

- Existing solar system information
Property Owner
Property owners should confirm whether the electricity account and property ownership details are available for the project.
Tenant or Lessee
Tenants may need written approval from the landlord and should consider the remaining tenancy period before proceeding.
What Roof Information and Photographs Should I Prepare?
Roof information helps the provider understand the available installation area before arranging a formal assessment.
Useful roof details may include:
- Roof material
- Approximate roof dimensions
- Roof age
- Current roof condition
- Known water leakage issues
- Roof direction and slope
- Skylights or roof openings
- Water tanks or ventilation equipment
- Trees or buildings that create shading

What Project Goals Should I Explain?
Solar providers may recommend different systems depending on what the customer wants to achieve. Explain your priorities clearly during the initial enquiry.
- Preferred installation timeline
- Approximate project budget
- Whether you prefer direct purchase or financing
- Whether you are considering a battery
- Expected future increase in electricity usage
- Electric vehicle charging plans
- Planned property renovation or expansion
- Interest in monitoring and reporting

You should also tell the provider about future equipment that may increase electricity usage, such as air-conditioning systems, machinery, electric vehicles or business expansion.

Frequently Asked Questions
Do I need a site assessment before requesting a quotation?
Not necessarily. You may begin with basic property and electricity information. The provider may arrange a site assessment before confirming the final quotation.
How many electricity bills should I prepare?
Several recent bills may provide a more representative picture of your electricity consumption than a single month.
Can I request a quotation without roof photographs?
You may submit an initial enquiry, but clear roof photographs can help the provider understand the property before arranging an assessment.
Do I need to choose the system size myself?
No. The solar provider should recommend a suitable capacity after reviewing your electricity usage, property conditions and objectives.
What additional information is needed for a factory?
A factory may need operating hours, load data, maximum demand information, transformer details, roof plans and structural information.
Will my initial quotation be the final installation price?
Not always. The price may change after a detailed site assessment or if additional roof, structural or electrical work is required.
