Yes. This mainly depends on the intensity of solar radiation. The hot water is therefore around 8 degrees Celsius. Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
Cell manufacturers will indicate the performance parameters of solar cells under standard test conditions in their product specifications: generally including short circuit current Isc; the open circuit voltage Voc; the maximum power point voltage Vap; maximum power Pmpp; conversion efficiency Eff, etc. Under standard test conditions, the relationship between maximum power Pmpp and conversion efficiency isfollowing:
Pmpp = battery area (m2)*1000(W/m2)*Eff
For example:
Type conversion efficiency of product (%) Power (W)
Single crystal 125*125 15 2.22855
Single crystal 156*156 15 3.58425
Polycrystalline 125*125 15 2.34375
p>Polycrystalline 156*156 15 3.6504
Note 1: The test conditions are in accordance with the solar spectrum irradiation intensity AM1.5 1000W/m2, The battery temperature is of 25℃, the test method
complies with IEC904-1 standard and the allowable efficiency deviation ±5% REL.
Note 2: AM1.5
AM is the abbreviation of air mass, which means atmospheric quality.
AM1.5 is a condition that describes the average illumination of sunlight incident on the Earth's surface. The total solar irradiation is 1000W/m2 and the calibrated temperature of the solar cell is 25±1℃.
Note 3: IEC904-1
IEC: International Electrotechnical Commissionthe, international electrotechnical commission.
IEC904 is equivalent to GB/T6495.
Note 4: REL: energy loss rate energy loss rate
