Before you sign anything, get an honest, independent assessment of whether photovoltaic panels are a sound investment for your specific property, consumption habits and location.
Installers have a natural incentive to present optimistic projections. An independent assessment gives you the full picture — including the scenarios where solar may not be the right choice right now.
South-facing roofs in Portugal receive significantly more irradiation than east or west-facing surfaces. We assess your actual roof geometry, nearby obstructions, chimney shadows and seasonal shading patterns before any production estimate is made.
Your actual electricity bills tell a story that generic calculators miss. We examine your consumption profile across months and time-of-day patterns to understand how much of any solar production you would realistically consume yourself.
Portugal's solar resource varies considerably between Algarve, Alentejo, Lisbon, Porto and the interior. We use meteorological data specific to your municipality rather than national averages that can overstate or understate your situation.
Portugal's UPAC regulations and RESP injection tariffs change. We explain the current framework honestly, including the reality that grid injection rates are considerably lower than retail electricity prices and what that means for your financial case.
We model payback using Portuguese electricity price trend data rather than the optimistic escalation assumptions common in installer brochures. You see a range of scenarios — not just the best case.
We do not install panels, represent any manufacturer or earn referral fees. Our only output is an honest written assessment. If solar does not make financial sense for your home, we will say so clearly.
Every roof has a unique combination of pitch, orientation, surface area, and obstruction profile. A chimney that seems minor can cast meaningful shadows during winter months when sun angles are low. Neighbouring buildings, tall trees and even satellite dishes all affect production. We document these factors with precision so any production estimate reflects your actual situation.
The financial case for solar depends heavily on how much of the generated electricity you actually use yourself. A household that is empty during daylight hours — when panels produce most — may self-consume far less than one with people at home. We review your actual EDP billing data across all months to understand your consumption rhythm and model realistic self-consumption ratios.
We build the financial projection from the ground up using your specific data. Electricity price assumptions are grounded in historical Portuguese tariff trends rather than optimistic escalation rates. We show you a range of scenarios — conservative, moderate and favourable — so you understand the realistic spread of outcomes rather than a single number designed to look attractive.
Portugal genuinely has exceptional solar resources. The southern regions rank among the highest in Europe for annual irradiation. But irradiation is only one variable in a complex financial equation that also includes your roof geometry, consumption habits, system cost, regulatory tariffs and electricity price trajectory.
The installers who quote you have a commercial interest in proceeding. Their projections are often built on optimistic assumptions — high self-consumption ratios, favourable electricity price escalation, minimal degradation. An independent assessment applies more cautious, evidence-based assumptions to the same inputs.
Sometimes the result confirms that solar is a sound investment for your property. Sometimes it reveals that the payback period is longer than the installer suggested, or that your consumption profile makes the economics marginal. Either answer has value — because it is honest.
Read Our Commitment
Each assessment is structured around five core components. The written report you receive addresses each in turn, with findings specific to your property.
Orientation, pitch, shading obstructions, available area and structural context. The foundation of any accurate production estimate.
Review of your actual EDP electricity bills to understand monthly and seasonal consumption, and how it aligns with solar production hours.
Municipality-specific irradiation data applied to your roof parameters to produce realistic annual and monthly production estimates.
Clear explanation of current UPAC self-consumption rules and RESP injection tariffs, including what the gap between retail and injection rates means for your case.
A clear written document with scenario-based payback projections, key assumptions stated explicitly, and conclusions you can use when evaluating installer quotes.
Get an independent assessment before committing to any installation. Bring your EDP bills and we will do the rest.
