Ask about your projectAsk for the exact components and quantities in the proposed system, including storage, inverter and any gateway or charging equipment. A product-family name is not a complete specification. Request usable capacity, output limits, siting requirements and the electrical work included.
Explain whether your priority is storing solar, charging on a tariff, backup or future expansion. Ask the installer to separate the equipment required for each function and identify which capabilities are included on day one rather than possible future additions.
Ask who supplies the app account, configures the system and handles any network paperwork. Get product and workmanship warranty terms separately. If you want to expand later, request the exact compatibility and warranty conditions rather than a general promise that the system is expandable.
If you may add storage, vehicle charging or other electrical loads later, describe that intended change at the survey stage. Ask the installer to identify the capacity and space allowed in the initial design, the equipment that would need to be added and any work that would have to be repeated. Request the current compatibility conditions and explain your likely timescale. A statement that a product is modular does not tell you the eventual installed cost or establish that every future component will fit the original configuration.
Put the proposed component lists side by side. Compare usable storage and power limits separately, then look at the gateway, charging equipment, monitoring, installation location and electrical work. Check which features are included in the quoted total and which are optional. If one proposal includes backup and another does not, ask for a like-for-like version before judging the price difference. Have each company identify its commissioning, network paperwork and handover responsibilities. Keep the written specification with the quote so a change of model during procurement can be reviewed before installation.
Confirm who registers the equipment, gives you access to the app and helps with operating settings. Ask how faults are reported, who diagnoses them and how manufacturer warranty claims are handled. Product cover, installation workmanship and chargeable visits are different questions; obtain each answer before choosing an installer.
Use the linked manufacturer resource and confirm postcode coverage directly. Ask whether the company undertakes your specific installation, expansion or repair job.
Request a compatibility assessment using the exact models you already own. The installer should identify retained and replaced equipment and provide a complete specification.
Ask for equipment models and quantities, usable storage, electrical work, backup if required, commissioning, VAT treatment, network paperwork and separate product and workmanship warranties.
No. Company information and manufacturer status are different evidence. Check current manufacturer information and relevant registers before appointing a contractor.
Include your postcode, equipment details, whether this is a new or existing system and what you need the company to do. Choose an installer and confirm postcode coverage. Where online requests are available, your details go directly to the named business with your agreement.
