Is your site good for solar? A numbers-backed answer in 48 h

Scored solar pre-feasibility: 20+ years of irradiance, terrain slope, grid distance, local context — from rooftop to 10 ha project. From $29.

The problem

Before any solar engineering study — which costs thousands of dollars — you need to know whether the site holds up: actual irradiance, slope, distance to the interconnection point and local context rule out a good share of sites from the start. Many pay for the full study only to learn it too late.

The DataTerra solution

  • Your site's actual solar resource: 20+ years of NASA POWER history plus Global Solar Atlas — not a regional average
  • Terrain qualified: slope and aspect from the Copernicus GLO-30 digital elevation model
  • Grid connection objectified: distance to substations and lines (UPME data)
  • Local context in numbers: safety (SIEDCO), land use, constraints
  • FAVORABLE / CONDITIONAL / UNFAVORABLE verdict in 48 h — before paying for the engineering study

Frequently asked questions

Does this report replace an engineering study?

No — it comes BEFORE it. It saves you from paying for a full study on a site that doesn't hold up, and arms your conversation with the installer or engineer with sourced numbers.

Where does the irradiance data come from?

From three official public sources, cited in the report: NASA POWER (20+ years of satellite history at the exact point), the Global Solar Atlas (World Bank) and PVGIS (European Commission, SARAH3/ERA5 databases) for the production simulation. The report gives GHI/DNI irradiation, monthly seasonality and year-to-year variability.

Does it work for a simple rooftop?

Yes — that's the entry tier ($29): a point or under 500 m². The report is still complete: resource, seasonality, context.

Which countries do you cover?

Anywhere in the world: solar resource (NASA POWER, Global Solar Atlas, PVGIS), terrain (Copernicus GLO-30) and protected areas are global, and grid data comes from OpenStreetMap everywhere — replaced by the official UPME registry in Colombia. National registries (SESNSP crime data in Mexico, SIEDCO in Colombia…) are added automatically where they exist, at the same price. The order wizard confirms availability in real time.

Can the report estimate my system's production (kWh/year)?

Yes — the report integrates the PVGIS calculator from the European Commission's Joint Research Centre. Describe your system when ordering (power in kWp or panel area; roof with tilt and azimuth, or 1/2-axis trackers): the report delivers estimated annual and monthly production, detailed losses (incidence angle, spectrum, temperature) and year-to-year spread. With no configuration, a standard 5 kWp estimate at optimal angles is included.

Can I simulate an off-grid system (batteries)?

Yes — provide the battery capacity (Wh) and daily consumption: the report estimates energy captured, the percentage of days with a full battery and the days where demand is not covered — enough to size battery and panels before buying hardware.

Are terrain and cast shadows taken into account?

Yes — the report includes the site's real horizon diagram (PVGIS): the profile of surrounding mountains and hills overlaid with the sun paths at summer and winter solstices, plus terrain slope and orientation (Copernicus GLO-30, 30 m). Distant masks are therefore counted; nearby obstacles (buildings, trees) require a site visit or a drone mission.

How do you assess grid connection?

The report measures the distance to the nearest substations and high-voltage lines: official UPME registry in Colombia, OpenStreetMap in the rest of the world (completeness varies by area — the report states it honestly). It is a pre-feasibility indicator, to be confirmed with the grid operator.

Can I see a report before buying?

Yes — a complete, real example (Magdalena department, Colombia) can be downloaded at the top of the page.

Ready to qualify your solar site?

This report is a decision-support tool based on public data (satellite, grid, terrain). It does not replace an engineering study, on-site measurement or a formal interconnection request, and DataTerra's liability does not extend beyond the quality of the aggregation and interpretation of the cited sources.
