calculation photovoltaic solar systems for isolated dwellings
One of the biggest factories in Spain for photovoltaic solar energy is focused specifically on residential lighting , country houses, livestock shelters and ships where the cost of grid connection is too expensive.
Basically the number of solar panels is determined by the consumption of plant receptor expressed in Ampere / hour and place of the same situation. A module gives us a greater amount of energy as receive more radiation, so for the same instalacisn not used the same panel in Bilbao nzmero in Badajoz.
Another key element in a photovoltaic instalacisn are found tambiin Baterman closely linked to the use and the instalacisn situacisn. Thus the greater the possibility of cloudy DMAS, the greater the capacity of the Baterman and vice versa. As a general rule not be calculated within 5 DMAS autonomma of Baterman increased to 8 or 10 DMAS in areas with abundant cloudiness
To set the number of panels required will be based on the current per msdulo in the case of square cilulas 95 by 95 mm is 2.4 amps. This value can vary in type msdulo funcisn used so this case is considered variable
Example of calculation of panels for a weekend home in Madrid utilizacisn
Saturdays and Sundays all Dining
dma applied fluorescent 20w-12v-5h/dma-2dias = 16 Ah / week. Kitchen
apply fluorescent 20w-12v-2h/dma-2dmas = 6 Ah / week.
Bedrooms "" 3 * 20w-12v-1/2h/dma-2dmas = 4.8 Ah / week.
WC "" 15w-12v-1h/dma-2dmas = 2.5 Ah / week. TV
"25w-12v-5h/dma-2dmas = 20.8 Ah / week. Water Pump
60w-12v-1h/dma-1dma = 5Ah/semana. TOTAL
55.5 Ah / week
Data Madrid radiacisn available to us indicates an annual average of 4.72 peak sun hours for inclinacisn 45: south-oriented and thus a 2.4-amp msdulo
we will produce peak sun
4.72 hours * 2 , 4 A = 10.32 A / peak * 7 DMAS = 74.24 hours / week
Then nzmero of msdulos be:
N: msdulos = consumption / produccisn of msdulo
N: msdulos = 55, Ah consumo/74 5, 24 = Approx 1 panel produccisn
