3. System design and customisation
A good installer will take the time to understand your energy needs, roof structure, and budget before proposing a system design. They should be able to explain the rationale behind their recommendations and tailor the system size and components to maximise your energy production and financial return.
4. Transparency and communication
A trustworthy installer will be upfront and transparent about all aspects of the solar installation process, including pricing, warranties, timelines, and potential challenges. They should readily answer your questions in clear and concise language. Don’t hesitate to ask for clarification on any aspect you’re unsure about.
5. Warranties and after-sales service
A comprehensive warranty on both the installation work and the solar system components is crucial. Inquire about the length and coverage details of the warranties offered by the installer and the manufacturers. Additionally, understand the after-sales service protocols. Will the installer be readily available for maintenance and troubleshooting in the future?
