How will I use my time in the best way?
I’ll focus on the math functions and visuals, and make sure I finish my part on time. That way, I can help my group with anything they need and make sure everything’s ready and looking great before we present.

Solar panels are flat devices made of small parts called solar cells, usually made of silicon. The top layer is glass to protect the cells.

Solar panels change sunlight to electricity. When sunlight hits the cells, it makes tiny particles called electrons move, creating power. This power is sent to a device called an inverter so we can use it in homes.

Solar panels are amazing because they use sunlight to make clean energy without causing pollution. Done by : Maryam Eissa Alraeesi Grade : 8-1 Advance

The UAE is doing great with solar power! They've built huge solar plants like the Noor Abu Dhabi Solar Plant and the Mohammed bin Rashid Al Maktoum Solar Pork in Dubai. These projects help produce a lot of clean energy.

Now, solar energy is mostly used in cities like Abu Dhabi and Dubai, and in desert areas where there's a lot of sunlight. The Northern Emirates (like Sharjah or Ras Al Khaimah) have solar power too, but not much.

There are still places in the UAE where solar energy isn't fully used, in small cities (like Ajman) far from big cities. But the UAE is planning to use solar energy everywhere, including putting solar panels on roofs and creating new solar projects to help the country use 50% clean energy by 2050!

2. Resources required to make a solar panel

To make a solar panel, you need a few important materials. The main one is silicon, which is used to make solar cells that catch sunlight and turn it into electricity. You also need metal wires like copper to connect the cells, and glass to protect them. The panel is usually held together with a frame made of aluminum, and small parts that help control the flow of electricity. All these materials work together to make a solar panel that can produce clean energy from the

sun.

1. Use formula - Show how solar energy works:

   Energy = Efficiency x Sunlight hours x panel area

2. Choose a tool - Use canvas or PowerPoint to design

3. Get data - Find out how much energy panels make and how many hours of sunlight

4. Show the math - Example :

   “Energy = 0.15 x 6 hours x 10m2 = 900 wattas / day

5. Add pictures - Use icons of the sun, solar panels, and energy

6. Colours / Fonts - Use yellow and green, with easy-to-read fonts

7. Keep it simple - Make the Math easy to understand

8. Save / share - download and share it

   
   

   
   

Answer: when it’s hot solar panels, make less power this happens because it makes it harder for panels to change sunlight into electricity, so they become less efficient in warm temperature.

I’ll look at the average temperatures in Brazil, India, and South Africa and predict how much power solar panels can produce in each country.

Step 1: Average Temperatures

• Brazil – 25°C (77°F)

• India – 27°C (81°F)

• South Africa – 18°C (64°F)

Step 2: Power Output Formula

We use this formula:

Power Output (kW) = (Temperature × 0.5) + 5

Step 3: Power Output Calculations

• Brazil: (25 × 0.5) + 5 = 12.5 kW

• India: (27 × 0.5) + 5 = 13.5 kW

• South Africa: (18 × 0.5) + 5 = 14 kW

Step 4: What We Notice

• Higher temperatures = more power, but South Africa’s cooler climate still produces good power.

• Other factors like sunlight hours and weather also affect solar power.

In winter days

Winter temperatures in the UAE average between 18°C to 25°C (64°F to 77°F) during the day, and from 10°C to 15°C (50°F to 59°F) at night.

1. Identify intervals where the graph increases or decreases.

   Answer: In the graph it increases at point 15. And decreases at point 30.

2. What is the ideal temperature for maximum power output?

   
   

   Answer: The maximum power output is 30.

3. Interpret the relationship between solar power output and temperature.

   
   

   Answer: Solar power increases as Temperature increases however when the temperature is too high, for example 35°C it will decrease because of the amount of heat, as well as pressure.

N = C/P

N = 19,100,000/1,500 = 12,733

N =12,733

To summarize, Masdar City would need approximately 12,733 solar panels to meet its energy needs.

1. Hot places: Use cooling systems and leave space for airflow.

2. Cold places: Tilt panels at a good angle and use anti-snow coatings.

3. Cloudy places: Get high-efficiency panels and batteries to store energy.

KWh: 19.1 billion per year

MWh: 19.1 million of electricity per year

2. Neom (Saudi Arabia)

KWh: 50 to 60 billion of electricity per year

MWh: 50 to 60 million of electricity per year

3. Songdo (South Korea)

KWh: 2.4 billion of electricity per year

MWh: 2.4 million of electricity per year

1. Masdar City's Energy Demand:

   • Masdar City is designed as a low-energy and sustainable city.

   • Estimated energy consumption: 100-150 MW (megawatts).

2. Solar Panel Output:

   • A typical solar panel produces 300-400W (0.3-0.4 kW).

   • Assuming 5 peak sun hours per day, a 400W panel generates about 2 kWh/day.

Calculation:

• Let’s assume Masdar needs 120 MW (120,000 kW) continuously.

• Per day, that’s 120,000 kW × 24 hours = 2,880,000 kWh/day.

• One 400W panel generates 2 kWh/day.

• Panels required = 2,880,000 ÷ 2 = 1,440,000 panels.

So, around 1.4 to 1.5 million solar panels would be needed to fully power Masdar City! ☀️🔋
