We do not subcontract responsibility: whoever surveys the project sees it through to handover. Every site is on record: works documentation, testing and written warranties. What stays with the client when the team leaves the site International operations ## Present in four European markets We work in countries with different technical regimes. The code and the language are local; documentation and handover follow the same standard in all of them. PortugalHead office · Santo Estêvão, Santarém BelgiumBrussels and Antwerp GermanyBerlin, Frankfurt and Munich England European presence Why WChampion ## The standard applied to every project ### Delivery with method Every project is surveyed, planned and handed over through the same process. No improvisation, no variation depending on who is on site. ### Present in four markets Portugal, Belgium, Germany and England. Real capacity to work under different national standards. ### European compliance Site signage to EN ISO 7010, safety coordination and certified protective workwear matched to each type of risk. ### Four disciplines, one company Energy, HVAC, construction and electrical infrastructure under single technical management, so the client is not passed around. ### Contractual clarity Schedule, scope and conditions in writing before starting. Anything that changes during the works is flagged before it happens. ### Documented warranties 25 years on solar panels and 10 years on inverters, with test reports and photographic record of the works. Team and vehicles identified on site, at a solar farm Projects and delivery ## Experience from real sites [See all →](https://wchampion.pt/projectos.html) Solar Energy ### Large-scale photovoltaic plant Germany · Industrial Construction ### Building under construction Portugal Infrastructure ### Mounting structure in open field Germany Solar Energy ### Cable infrastructure and grid connection Germany · Industrial Where we stand We deliver with method. *We document what remains.* Technical works must still perform in ten years, and whoever commissions them needs to be able to check that. So we document everything we do. [How we work →](https://wchampion.pt/sobre.html) Request a quote ## For projects that demand a proper standard. Tell us what you need.
