Design the ground frame for your solar plant
Solispec picks the profiles and posts, checks the frame against snow and wind to the DBN and prices it down to the last bolt.
Norms explained
- DBN V.1.2-2:2006 “Loads and actions”: what matters for a solar plantThe clauses of the Ukrainian loads code a solar array needs: S₀, W₀, the factors, Changes 1 and 2, and a worked example for Kyiv.
- DSTU-N B V.1.1-27:2010: climatic regions and Tmin for PV stringsBuilding climatology for a solar plant: Ukraine’s climatic regions, the minimum temperature and why the string length depends on it.
- PUE:2026 for solar plants: what changedPUE:2026 replaced PUE:2017: scope, common earthing with the building and surge protection for a solar plant.
- DBN V.2.5-23:2025 (from 01.01.2026): what applies to solarThe new Ukrainian code for building electrical installations: lightning protection, SPDs, fire-rated penetrations, conductor sizing and PV cables.
- DSTU HD 60364-7-712:2022: the electrics of PV systemsUkraine’s main PV electrical standard: U_OC MAX in frost, I_SC MAX, string fuses, cables under modules, SPDs and earthing.
- DSTU-N B EN 1993-1-3:2012: designing C-profiles for PV mountingWhy a perforated 41×41 C-channel is checked to Eurocode 3 rather than DBN V.2.6-198: effective section, γ_M factors, bolts in slots.
- DBN V.2.6-198:2014 “Steel structures”: tubes in PV framesHow the Ukrainian steel structures code applies to closed tubes in a ground PV frame: Ry, γm, the buckling factor φ and the checks Solispec runs.
- DSTU EN 62305-1…4: lightning protection for solar plantsThe four parts of DSTU EN 62305-1…4 for a solar plant: risk assessment, separation distance, SPDs. There is no rule that PV always needs lightning protection.
