Climate: Houston Texas summers are hot and can be very humid. The winters are cool and moderate with mixed cloud cover year-round. The hot season lasts from early June to late September with temperatures ranging from 65°F at night, to 100°F during the day. The coolest period is from late November to late February with temperatures ranging from 50°F to 76°F.
Solar Power Conditions: The seasonal variation for solar power use is significant, with the best period from early April to late July and the least favorable period from mid-November to early February. Peak power period is in June with energy levels over 6 kW per hour of daylight per square meter or up to 100 kW per day per square meter. During the low light period from mid-November to early February, energy drops to less than half its peak in June.
Humidity: Houston relative humidity remains significant from April to November. Very humid conditions occur from May to October, creating excellent environment for WaterSeer.
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.
Houston area estimated yield: Houston, Texas, particularly coastal areas, is an excellent location for WaterSeer deployment. Quarterly yield below is estimated for a small ten-unit WaterGrid installed with the geothermal module. Three types of installations are shown:
- Outside, such as a garden or greenspace in the Houston region.
- Hydroponics grow-house or vertical farm.
- Coastal deployment, such as near ocean facilities and off shore islands.
Sources and Data: Weather data and models are derived from historical weather reports January 1, 1980 to December 31, 2016. Yield estimate is from Sonoma Yield Forecast Model. Data graphics are from weatherspark.com and waterseer.org.
