From site assessment to grid connection. We size the system on real consumption, even where the roof could take more panels, and hand over the calculation in writing before installing.
A photovoltaic system produces for 25 years or more. With comparable panels, what separates a good installation from a poor one is the sizing, the structure and the quality of the connection.
That is why the calculation comes before the installation: capacity, estimated output and payback, in writing. If the numbers do not work for your consumption, we say so.
A photovoltaic installation is only complete when whoever commissioned it holds the documentation they need: for the insurer, the audit, a funding application, or the day something fails. We hand it over in writing.
What was installed, where, and with which materials: row layout, electrical schematic, strings and protective devices. It reflects what was actually built, including any changes to the original design.
as builtThe measurements taken before handover: continuity, insulation, polarity, protection response and verified output under load. The report records the measured values.
at handoverThe CE declaration for every piece of equipment installed, and the declaration for the installation itself. These are the documents the insurer asks for after an incident, and that an energy audit can request without notice.
per item of equipmentPanels, inverters and workmanship, each with term, scope and the party responsible.
25 and 10 yearsTo all of this we add the photographic record of what ends up buried or covered, taken before backfilling while it is still visible.
Significant bill reduction, sized on actual consumption.
25 years on panels and 10 years on inverters, in writing.
Panels with an efficiency above 22%, stated on the datasheet.
The payback period is calculated per project and delivered before installation.
Solar farms with fixed-tilt or tracker structures, including transformer substation and medium-voltage grid connection.
See detail →Installation on warehouse roofs, with prior structural check and fixing suited to the roof type.
See detail →Systems sized to the building’s consumption, with or without battery storage.
See detail →Siting starts with the ground: boreholes to define the structure foundation, a topographic survey for row inclination, and a shading study across the year. Only then are the installed capacity and the medium-voltage route fixed.
An industrial roof does not always carry what you want to put on it. The structural check comes before the quotation, and the fixing method follows the roof type (sheet, sandwich panel, fibre cement or slab).
The system is sized on the building’s consumption, read from the bill and from the load profile across the day. The sizing criterion is the share of consumption covered by on-site generation.
It depends on capacity and licensing. An industrial rooftop is measured in weeks; a plant with a substation, in months. The schedule is set out in the proposal and is not estimated over the phone.
In Portugal it depends on capacity. Up to 700 W is exempt. From 700 W to 30 kW requires prior notice to DGEG. From 30 kW to 1 MW requires registration and an operating certificate. Above 1 MW, production and operating licences.
We check the structure before proposing. If it cannot, we say so and present the ground-mounted alternative where land is available.
Yes. Preventive maintenance keeps output within forecast across the 25-year panel warranty.
