SOLAR SAVINGS
CALCULATOR
Estimate your savings using real Uzbekistan tariffs, solar radiation data, and DETOS pricing. No email required.
Peak sun hours (PSH) are the equivalent number of hours per day when solar radiation averages 1,000 W/m² — the standard test condition for solar panels.
Data source: Global Solar Atlas (World Bank / Solargis). Values vary by season — from ~2.5 in winter to ~6.0 in summer. Annual average for Tashkent: 4.8 PSH.
