Solar energy blog
Analysis, context and practical advice on solar energy in Colombia, held to the same standard of transparency as the rest of the site.
In short
The NodoSolar blog analyses the solar energy market in Colombia with data and sources: how costs are evolving, regulatory changes (CREG, UPME), tax incentives and sector trends. Every article shows its publication date and is corrected when the regulation changes.
Solar Panels in Condominiums: How the Decision Is Made
A building's roof is common property and the investment is approved in assembly. Ley 675 de 2001 sets the majority required, and the answer depends on how the system is paid for.
Read BusinessSolar Energy for Agribusiness in Colombia
Irrigation, pumping and cold chain consume exactly when the sun produces. On a farm, high irradiation, ample roofs and daytime load line up like in few other sectors.
Read TariffsEstrato and solar savings: why your neighbour saves more than you with the same panels
Two identical houses with the same system can save very different amounts. The difference is not in the panels: it is in what each one pays per kilowatt-hour.
Read FinancingCan you pay for solar panels with what you save on the bill?
'The instalment pays for itself' is the sector's most repeated sales line. Sometimes it is true. This is the calculation that tells you whether it is true in your case.
Read BusinessWhy a business recovers its solar investment sooner than a home
The same technology, two different financial cases. In a Colombian company four factors line up that in a home rarely occur together.
Read TariffsWhy does your neighbour pay less for electricity than you?
Same block, similar houses, bills that look nothing alike. There is almost always a concrete explanation, and it is written on the bill itself.
Read InstallationDo solar panels damage your roof? The answer depends on something almost nobody checks
The roof is the only component of the system that was already there and that nobody chose. It is also the one that decides whether, ten years from now, you have an installation or an argument.
Read PaybackHow long until it pays for itself? Why that figure says less than it seems
Almost every quote comes with a payback period. Almost none comes with the four assumptions that produced it, and without them two figures are not comparable.
Read SavingsSelf-consumption and exports: why two identical homes do not save the same
Two homes with the same system and the same bill can save different amounts. The difference is not in the panels: it is in the clock.
Read OutlookSolar energy in Colombia: the outlook in 2026
Falling costs, incentives still in force and a settled net metering framework make 2026 a good moment to assess solar energy in Colombia.
Read PracticalHow to tell whether your home is a good fit for solar energy
Not every roof is equally good for panels. These are the factors that determine whether your house will make good use of a solar installation.
Read MythsCommon myths about solar energy in Colombia
A lot of mistaken ideas circulate about solar energy. We go through the most common ones in Colombia and what the reality is.
ReadHow we write
Our editorial line
In a sector with plenty of promises and few verifiable numbers, these are the rules we hold ourselves to before publishing.
Every figure carries its source
Regulatory and market data are cited with the regulation or body behind them — CREG, UPME, Ley 1715 de 2014, Ley 2099 de 2021 — and not with a generic claim. If a figure cannot be backed up, it is not published.
Articles carry a visible date
The sector changes: a new resolution can make a correct article obsolete. That is why every piece shows its publication and last review date, and is corrected when the regulation changes rather than left to age.
No content is disguised advertising
We do not recommend module brands or specific installers inside the articles, and we do not accept payment for editorial mentions. When something has a downside, we say so.
Facts are kept distinct from estimates
A value taken from a regulation and an in-house estimate are not presented the same way. Ranges are declared as ranges, with the assumptions on show, so you can judge whether they apply to your case.
Beyond the blog
Where the rest of the content lives
The blog covers the landscape and current developments. The operational and comparative material lives in other sections.
Practical guides
Operational step-by-steps: how many panels you need, how to read your bill, how to compare quotes or how to legalize the system with the grid operator.
ExploreComparisons
Decisions weighed up with judgement: monocrystalline versus polycrystalline, with batteries or without, microinverters versus a central inverter.
ExploreGlossary
The terms that appear in any quote — kWp, AGPE, net metering, PSH, degradation — defined in a sentence and with their Colombian context.
ExploreReference prices
Investment ranges by system size, with the methodology and observation date declared, so you can tell whether a proposal is in line with the market.
