This article tackles important questions you need to ask before choosing a solar installer. Solar Ekiti Knowledge Center is here to guide you in making informed decisions.
What is the system designed to power?
A quotation should be connected to a use case. If an installer cannot explain what assumptions were used to select the inverter, battery and panel configuration, it is difficult to judge whether the system is appropriate.
What exactly is included?
Ask for the equipment list, ratings, quantities and installation scope. Confirm whether mounting materials, protection devices, cables, labour and commissioning are included in the price.
What happens if my requirement is larger than the package?
A responsible installer should be willing to recommend assessment or a different system rather than force every customer into the same configuration.
How will the system be supported after installation?
Ask how technical problems, maintenance requests and future upgrades are handled. Solar is a long-term asset, so after-sales support matters.
What warranty applies?
Warranty terms can vary by manufacturer and component. Ask for the applicable warranty information in writing and understand what is covered, what is not covered and how a claim is handled.
Can the recommendation be explained in plain language?
You do not need every engineering calculation, but you should understand why the proposed system was selected and what its limitations are. Clear communication is a sign of a better purchasing process.
