Your free guide to solar in Northern Portugal
Real 2026 costs, the honest case for and against a battery, DGEG paperwork explained, and the questions to ask before you sign anything. Included free in every Minho Solar account.
The Free Guide is the same honest starting point we wish we had before buying solar ourselves: real regional numbers instead of a national-average sales pitch, written for homeowners in the Minho specifically. It now lives in your dashboard instead of a one-off PDF, so you can come back to it, save your tool results alongside it, and move straight into a Blueprint report when you are ready.
What’s covered
The day the grid went down
What the April 2025 Iberian blackout actually revealed about grid-tied systems without a battery, and the one question that exposes it in any installer conversation.
The honest numbers
What grid-tied, hybrid, and full off-grid systems really cost in the Minho in 2026, at the 23% VAT rate that applies today.
Is it worth it in the north
The honest case for and against solar at northern irradiance levels, so you can tell whether your own roof and usage make the numbers work.
What goes wrong
Seven ways a quote can quietly overstate what a system will do for you, from oversized panels to missing DGEG registration.
Questions to ask any installer
Eight direct questions that separate an honest quote from a sales pitch, before you sign anything.
Registration, insurance and incentives
DGEG and UPAC registration explained in plain English, plus the IRS and IMI incentives actually available in 2026.
