Request for Quotation (RFQ) - Residential Solar Power System We are seeking a comprehensive quotation for the supply, delivery, and professional installation of a grid-tied or hybrid residential solar power system with the following key specifications: System Core Components & Specifications: Inverter: 12 kVA high-quality inverter (e.g., Deye or equivalent approved brand). Battery Storage: Approximately 10 kWh to 12 kWh nominal capacity using Greenrich batteries or equivalent, high-cycle, deep-discharge LiFePO4 batteries from a reputable brand. Solar PV Panels: A total array output of approximately 6.5 kWp (Kilowatt-peak). This should be achieved using high-efficiency panels, ideally 12 x W Canadian Solar panels or equivalent panels with comparable or better wattage/efficiency ratings. System Design: The system should be designed to maximize solar harvest, ideally with a PV array input significantly higher than the inverter's capacity (e.g., PV array power>Inverter capacity) to ensure maximum power generation during peak sunlight hours. Ancillary Equipment: The quote must include all necessary balance-of-system components, including but not limited to: mounting structure (roof-specific), DC and AC protection devices, cabling, isolators, change-over switches, breakers, and a Wi-Fi monitoring module. Scope of Work: The quotation must cover the following: Supply of all specified and necessary components. Transportation and Delivery to the installation site (location to be specified). Professional Installation, commissioning, and system handover by qualified and certified technicians. This must include all labour, accommodation, and travel costs associated with a full installation process, including required travel for material collection (if applicable). Certificates of Compliance (CoC) and all necessary documentation upon completion. Quotation Format: Please provide a detailed quotation that clearly separates the costs for: Equipment/Materials Cost (Itemized List) Installation/Labour Cost Transportation/Logistics Cost Total System Cost (excl. and incl. VAT) We require a system that is robust, reliable, and capable of handling significant loads, including a standard electric geyser.
Looking for an 8kw Hybrid Inverter with about 16 panels and battery storage to provide 25kwh. System must be able to add a diesel generator input. Goal being to be off grid form eskom. Roof surface is mostly east west. Approximate area is 6.5 x 5 meters each side of the roof. A solar geyser needs to fit on the roof in the future as well.
Already installed Solar fir the whole house & Geyser & granny flat, NOW IS NOT WORKING, I NEED it to be checked all of & do maintenance. 2. GAS GEYSER, to be installed on GRANNY flat & ROUNDVEL AROUND MAIN HOUSE OR WE CONNECT SOLAR TOWARDS THE WHOLE HOUSE & OUTSIDE ROOMS & TO IMMEDIATELY GET TO ELECTRICITY SHOULD IT BE COLD AUTOMATICALLY
Good Morning Could you please provide an updated quotation as per the attached? Kindly forward your estimates to me at your earliest convenience. Kindly ensure that all quotes are addressed to me or another member of the Purchasing department. Please also refrain from discussing pricing with anyone outside of Purchasing.

Hi We are currently developing a new residential project consisting of six townhouses and would like to request a quotation for the electrical work, including both material supply and installation. I have attached our draft BOQ as a reference, along with the architectural and electrical drawings. Please note that the BOQ is a preliminary document and should not be considered final or complete. We are looking for your expert input on the material and installation scope to ensure a comprehensive and accurate proposal. For the finishing fittings (e.g., switches, outlets, and light fixtures), please provide a provisional sum rather than a fixed cost. We will finalize the selection of these items at a later stage. If any further information is required please feel free to contact me. Regards,
