During winter, daytime temperatures in the UAE are typically around 15°C - 20°C.

Observing the data pattern, as temperatures decrease (but remain above freezing), solar panels tend to perform more efficiently due to lower heat-related energy losses.

Since 15°C - 20°C is lower than the UAE’s yearly average of 28.9°C, the power output is expected to be lower than 1905 Wh but not significantly reduced.
Estimated winter output: Around 1600 - 1800 Wh

Final Answer:

On an average summer day in the UAE: Estimated power output is 1800 - 1900 Wh.

On an average winter day in the UAE: Estimated power output is 1600 - 1800 Wh.

Final Answer:

On an average summer day in the UAE: Estimated power output is 1800 - 1900 Wh.

On an average winter day in the UAE: Estimated power output is 1600 - 1800 Wh.

I'll start by graphing the function P=90(−1.2T)P = 90(-1.2T)P=90(−1.2T) to analyze the relationship between temperature and efficiency. Then, I'll determine whether the function is linear or nonlinear, interpret the values of 90 and -1.2, and calculate the solar panel efficiency for UAE, Japan, and Finland.

1. Is the function linear or nonlinear?

The given function is:

P=90(−1.2T)=−108TP = 90(-1.2T) = -108TP=90(−1.2T)=−108T

Since this equation is in the form of P=mT+bP = mT + bP=mT+b, where m=−108m = -108m=−108 and b=0b = 0b=0, it represents a straight-line equation. Therefore, the function is linear because it has a constant rate of change (slope of -108).

2. Interpretation of 90 and -1.2

90: This number is a multiplier, but in the given function, it does not represent the initial efficiency directly. Instead, it scales the effect of temperature on efficiency.

-1.2: This represents the rate at which efficiency decreases per degree Celsius increase in temperature. The more negative this value is, the faster efficiency drops as temperature rises.

3. Calculating Solar Panel Efficiency for Selected Countries

We use the equation:

P=90(−1.2T)P = 90(-1.2T)P=90(−1.2T)

UAE (Temperature: 28.9°C)

P=90(−1.2×28.9)P = 90(-1.2 \times 28.9)P=90(−1.2×28.9)

Japan (Temperature: 12.4°C)

P=90(−1.2×12.4)P = 90(-1.2 \times 12.4)P=90(−1.2×12.4)

Finland (Temperature: 3.3°C)

P=90(−1.2×3.3)P = 90(-1.2 \times 3.3)P=90(−1.2×3.3)

I'll calculate these values now. ​​

4. Solar Panel Efficiencies:

UAE: -3121.2%

Japan: -1339.2%

Finland: -356.4%

These values are not realistic because efficiency cannot be negative. This suggests there might be an issue with the function's formulation—possibly a mistake in the equation structure. Should we check the original function or consider an alternative form, such as:

P=90−1.2TP = 90 - 1.2TP=90−1.2T

2. Is the Graph Linear or Non-Linear?

The graph is non-linear because:

A linear graph would show a constant rate of change (i.e., a straight line).

Here, the power output increases at a varying rate until July, then decreases at a varying rate until December.

The shape resembles a parabolic curve (upward and downward slope), indicating non-linearity.

3. Finding PPP (Solar Panel Output per Year)

The total annual solar panel output PPP can be estimated by:

P=∫012f(t)dtP = \int_{0}^{12} f(t) dtP=∫012​f(t)dt

Where f(t)f(t)f(t) represents the monthly power output function.

To approximate PPP:

Find the average power output per month (taking values at key months like January, July, and December).

Sum up monthly values to estimate the yearly output.

Alternatively, use a function like a sinusoidal model:

P(t)=Pavg+Asin⁡(2π12(t−t0))P(t) = P_{\text{avg}} + A \sin \left(\frac{2\pi}{12} (t - t_0) \right)P(t)=Pavg​+Asin(122π​(t−t0​))

Where:

PavgP_{\text{avg}}Pavg​ is the average solar output over the year.

AAA is the amplitude (difference between peak and average).

t0t_0t0​ shifts the function to peak at July (t = 7).

This method allows a smooth estimation of yearly total energy production.

Simple answer

The graph is non-linear because solar power output changes at a varying rate, increasing from January to July (reaching its peak) and then decreasing until December. This creates a curved pattern rather than a straight line. To estimate the yearly solar output (PPP), you can add up the power generated each month or find the average monthly output and multiply it by 12.

You need to design a way to reduce the cost of cleaning solar panels while keeping their power output high. Here's how I would approach the problem:

Should the cleaning process be manual or automatic? Why?
The cleaning process should be automatic. Automatic cleaning would be more efficient because it reduces the need for manual labor and ensures that the panels are cleaned regularly without human intervention. It also helps keep the system running smoothly, especially in areas with a lot of dust.

How often should the panels be cleaned? What factors might affect this decision?
The panels should be cleaned based on how much dust has built up. If dust storms happen often, the panels might need cleaning more regularly. Factors like the amount of dust in the area, the weather, and the performance of the panels (how much power they’re losing due to dust) will affect how often they need to be cleaned.

How does the amount of dust on the panels impact your design?
The design should include a sensor system to detect how much dust is on the panels. If the dust level gets too high, the system can automatically clean the panels. This will make the cleaning process more efficient and ensure the panels are always producing the most power possible.

I think that to make solar panel cleaning more affordable we can make the machine manual so that it will coast lest and we only have to clean it once a year so that we don't waste time in cleaning
