Introduction
In the solar industry, a quotation is more than just a price tag—it is a legal document, a technical blueprint, and a first impression. A poorly written quotation creates doubt, while a professional one builds trust.
At SIMPSTRUCT, we prioritize clarity and structure. Whether you are a homeowner reviewing a bid or a technician looking to level up your business, this guide will show you exactly what a professional solar quotation must include.
1. The Header: Brand Identity
Your quotation must look official. Professionalism starts with your letterhead.
Must-haves: Your company name (SIMPSTRUCT), contact details (Phone, Email, Office address), and a unique Quote Number.
Date & Validity: Solar prices (especially batteries and panels) fluctuate. Always state that the quote is valid for only 3 to 7 days.
2. The Technical Breakdown (The Load Profile)
Never give a price without explaining what that price covers. Before listing equipment, list the load capacity.
Example: "System designed to carry: 4 LED Bulbs, 2 Standing Fans, 1 LED TV, and 1 Laptop for 12 hours."
Why? This protects you if the client later tries to plug in an electric iron and the system fails.
3. Itemized Equipment List
Don’t just write "Solar System - 500k." Break it down so the client sees the value.
Inverter: State the capacity and wave type (e.g., 1.5KVA Pure Sine Wave Inverter).
Batteries: State the technology and capacity (e.g., 200Ah 12V Tubular Battery).
Solar Panels: State the wattage and type (e.g., 300W Monocrystalline Panels x 2).
Charge Controller: Mention the type (e.g., 60A MPPT Controller).
4. The "Invisible" Costs: Accessories & Logistics
Many amateur installers lose money by forgetting these. A professional quotation includes:
Cables: DC solar cables and AC internal wiring.
Protection: Circuit breakers, changeover switches, and battery racks.
Labor: Professional installation fees.
Logistics: Transportation and site delivery.

5. Terms and Conditions (The Safety Net)
This is where SIMPSTRUCT shines. Add these three clauses to every quote:
Warranty: Clearly state what is covered (e.g., "1-year warranty on Inverter, 25 years on Panel performance").
Payment Terms: (e.g., "70% upfront for procurement, 30% after successful installation").
Client Responsibility: (e.g., "The client must provide a secure, shaded area for battery storage").
Conclusion
A professional quotation is about simplifying the structure for the client. When they see exactly where their money is going, they feel safe "closing the deal." At SIMPSTRUCT, we believe transparency is the foundation of every successful system.
