Find Out How Many Solar Panels Are Needed To Power A Hot/Cold Air Conditioner And Keep Your Home Comfortable All Year Round.

With the weather becoming increasingly unpredictable, a hot/cold air conditioner can be essential to maintaining comfort at home. But the electricity bill can be frightening. The good news is that with solar panels, you can use your air conditioner for free! Let’s find out how many solar panels are needed for that.

First, let’s choose a 12,000 BTU air conditioner. On the Procel label of the unit, we see that the average annual consumption is 484.6 kWh, considering 2,080 hours of use per year. This means it consumes 0.23 kWh per hour.

To find the monthly consumption, we multiply the hourly consumption by the daily usage hours and the days in the month:
0.23 kWh/hour x 8 hours/day x 30 days/month = 55.2 kWh/month

Step 2: Calculating The Energy Generated By A Solar Panel

Now, let’s calculate how much energy a solar panel can generate per month. We will use a 550 Wp (watts-peak) panel. The average solar irradiation in the city of Gramado is 4.51 kWh/m², and the system efficiency is 75%.

To simplify, the monthly energy generated is calculated as follows: 550 Wp x 4.51 x 0.75 x 30 ÷ 1000 = 55.8 kWh/month

Step 3: How Many Solar Panels Are Needed?

Now, let’s see how many solar panels are needed to meet the air conditioner’s consumption. The monthly consumption of the air conditioner is 55.2 kWh, and one solar panel generates 55.8 kWh per month. This means that a single 550 Wp panel is enough to power a hot/cold air conditioner of 12,000 BTUs.

You need one 550 Wp solar panel to use your hot/cold air conditioner for 8 hours a day, every day of the month, in a city like Gramado. This shows how solar energy can be an efficient and cost-effective solution for your cooling needs.

Um ar-condicionado da LG inverter de última geração 12.000 BTUs , consome:

22,8 kWh / mês consumo das 8 horas por mês = 182,4 kW x R$ 0,96 =
R$ 175,10

OU SEJA :

22,8 kWh : 30 dias = 0,76kw por hora

0,76 kW x 8 horas ligado = 6,08 kW

8 horas ligado gasta = 6,08 kW POR DIA x 30 = 182,4 kW x R$ 0,96 =
R$ 175,10

Um ar-condicionado 12.000 BTUs inverter , consome de 6 a 8 kWh por 8 horas, isso dependendo da marca . JAMAIS um ar-condicionado consumirá 0,23 kWh por hora … 55 kWh é consumo de geladeira.
