Location and Climate: New Delhi, India, is located at 28.6 deg North latitude, 77.2 deg East longitude. Elevation is just over 700 feet above sea level with small variation. Almost all the city of New Delhi is built up, although over 90% of the region within 50 miles is agricultural. The hottest period is from mid-April to early July with average daily temperature above 95F (35C). The cool period is from early December to mid-February with highs in the mid 70F (24C) and lows in the mid to high 40s (7C).
Solar Power Conditions: The environment for solar energy use is particularly relevant for this region to reduce power demand. The best period of the year is from early April to late June with energy per square meter above 6.8 kWh. The poorest period is from early November to early February with energy per square about 4.4kWh.
Humidity: Highest relative humidity is from late May to early October, nearly five months of hot, humid conditions, which is excellent for WaterSeer peak operations. This period roughly corresponds to the highest rainfall period, which is June through September. This high seasonal variation puts a premium on storage systems and reservoirs to capture water for the dry season from November through March.
WaterSeer Yield Curve: The WaterSeer yield curve is below. Yield is based on WaterSeer Sonoma model third party testing and trials under a wide variety of controlled and field conditions. Monthly yield is on the left vertical axis. The bottom horizontal axis is the average temperature. The Relative Humidity %(RH) is color coded in 10% increments.
New Delhi region estimated yield: New Delhi region, particularly riverine micro-climates, is an excellent location for WaterSeer deployment, particularly from May to November. Quarterly yield below is estimated for a small ten-unit WaterGrid installed with the geothermal module for three types of installations; outside, such as a garden or greenspace; a hydroponics grow-house or vertical farm, and riverine or surface water deployment, such as near rivers, ponds, and lakes. Power estimate is 0.35 kWhr.
