6G COMMERCIAL SOLAR LAB

Model the business.
See the energy case.

Built around the information a commercial decision-maker actually has: bills, operating pattern, usable roof and continuity requirements.

Residential Commercial

Site energy profile

Start with the bill, demand and operating pattern.

Business type Monthly electricity use

Maximum demand

Use the highest demand from bills or monitoring. Sanctioned / connected load

Used for interconnection headroom checks. Operating days / month

Future load growth

Planned expansion allowance. Grid / export mode Grid supply

How much consumption happens in daylight?

Used to estimate direct solar use. Export-enabled systems may offset more than the daytime-only load.

PV panel technology / model PVGIS accounts for temperature and irradiance. Module efficiency is informational; rated watts determine DC array capacity.

Pakistan default is UTC+5.

13.6% estimated combined lossPVGIS models irradiation, temperature and horizon. PVGIS models irradiance and temperature according to the module family; do not add efficiency or temperature-loss bonuses again. Bifacial rear gain is a site-based planning approximation. Dust and first-year/ongoing degradation are separate. Smog remains an additional seasonal scenario.
