QUESTION 1:
a) Estimate the optimum tilt angle (β) for solar panels in London.
[Resources/equations:
At solar noon in Southern hemisphere: α = 90 + ɸ - δ
At solar noon in Northern hemisphere: α = 90 - ɸ + δ
Where: δ is the declination angle (degrees); α is the Altitude (degrees); ɸ is the Latitude (degrees); and β is the solar panel/module tilt angle to the horizontal (degrees)
Annual solar tables to obtain the altitude angle at noon:

b) Use the ModuleSIM Excel file to examine how the energy output of the modules varies
throughout the year for different tilt angles near the optimum value for London. For example, ifyour calculated optimum tilt angle is 10°, simulate module performance at: 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, and 15° (In other words, ±1 to ±5° from the optimum tilt.). From the above, determine the daily, monthly and annual output (kWh) for each simulated tilt angle
(Use a solar module efficiency of20%, a module area of 100 m², and Day 15for all calculations in ModuleSIM. Assume that there is no tracking system to be used on the site. Assume theyear is a Common year with 365 days)
QUESTION 2:
Using the solar panel data sheet for Solibro provided, estimate the following:
(a) The temperature of Solibro solar panels (SL1-65F) they will be working at in July if they were to be installed in London.
(b) What is the expected new possible solar panels’Maximum power in July once installed in London.
[Assume the following:
• Assume London average temperature in July is 20.4 °C
• The average irradiance of London in July is 1028.46 W/m2
• Use the attached Data Sheet for Solibro
