4. a) Calculate the footprint (size) and cost of a solar farm to produce 1 MWh energy per day. The farm is located in an area with solar radiance equivalent to 5 kWh/m$^2$ and receives 10 hours sun per day. The farm is using solar cells made of polycrystalline silicon with 20% efficiency. The solar panels are made in 1m x 2m in size, and cost of each panel is $300. PTS: 10 b) If the output of the solar farm is used to produce hydrogen by electrolysis of water, calculate the volume of hydrogen produced at 500 atmosphere pressure. PTS: 10 c) Assume each fuel cell vehicle needs 5 kg of hydrogen on-board, how many fuel cell cars can be charged per day from the solar farm. PTS: 5

If your house requires 40 kWh of energy per day, how much would it cost you to install a solar panel? Given that the cost of installing solar panel is $3 per watt and the full sun hours in your area are 1123 hours per year. Please explain with steps. Thanks

The cost of a single solar panel lies in the range of 200 to 400 dollar, depending on the power output of the panel and the material it is made from. Before investing in equipping your home with solar power, it is wise to see whether the savings in the cost of electricity would justify the amount you would invest in the panels. (a) Suppose your monthly electrical usage equals the national U.S. household average of $948 \mathrm{kWh}$. Assuming an average of five hours of sunlight per day and a 30 -day month, calculate how many panels you would need to provide that amount of energy and what the total cost would be for each of the following two types of panels: (i) $140 \mathrm{W}$ panel that costs 210 dollar; (ii) $240 \mathrm{W}$ panel that costs 260 dollar. What is your conclusion? (b) Suppose you decide to install the $240 \mathrm{W}$ panels, and the average cost of electricity purchased over the next three years is $\$ 0.15 / \mathrm{kWh}$. What would the total cost savings be over that 3 -year period What more would you need to know to determine whether the investment in the solar panels would pay off? (Remember that a solar power installation involves batteries, AC/DC converters, wires, and considerable hardware in addition to the solar panels themselves.) (c) What might motivate someone to decide to install the solar panels even if the calculation of Part (b) shows that the installation would not be cost-effective?
A solar panel of 200 Wp has the following specifications: - Open circuit voltage: 22V - Maximum power voltage: 18V - Short circuit current: 13.2A - Maximum power current: 11A Calculate the size of a 12V battery if you want to store the energy produced by the 200Wp panel during 3 consecutive sunny days. Consider effective sun hour 4.5 hours and charging efficiency of charge controller is 85%.
