Frequently asked questions

What factors should I consider before hiring an installation company?

It is essential to evaluate the company's experience and track record, the quality of materials, their ability to perform a personalized study of your consumption and roof, as well as the comprehensive management of paperwork, subsidies, and after-sales service.

What is the standard process for a photovoltaic installation?

The process is usually divided into four phases: a technical feasibility study, the presentation of a final offer and quote, the management of administrative procedures and licenses, and finally, the execution of the installation.

Is it better to hire a large energy retailer or a specialized company?

Both options have advantages. Specialized companies usually offer a more comprehensive service that includes legalization and grant management, while energy retailers can integrate the installation with specific electricity tariffs. The ideal approach is to look for a company that combines technical experience with administrative management capacity.
