Calculating capacity of a solar hot water generation system
The capacity of a solar water heater plant depends on several factors, including the latitude, longitude, sunlight hours, and inclination angle. Here are the formulas to calculate the capacity of a solar water heater plant of 1000 LPD (liters per day), taking into account these factors: Latitude: The latitude of the installation site affects the angle at which the sun's rays hit the solar panels. The formula to calculate the solar altitude angle (SA) is: SA = 90 - latitude + δ where δ is the declination angle of the sun, which can be calculated using the following formula: δ = 23.45 * sin(360/365 * (284 + N)) where N is the day of the year (1-365). Longitude: The longitude of the installation site affects the local solar time, which is important for determining the peak solar insolation. The formula to calculate the local solar time (LST) is: LST = 12 + (4 * (T - 12) - (longitude - 15)) / 60 where T is the local standard time. Sunlight hours: The sunlight hours at the installation ...
