You are designing a residential solar power system and live in the typical home that uses an average of 900 KWH of electrical energy per month. You have heard that a Clearwater Power solar power test in Idaho found that a 1 KW solar array produced 1240 KWH in a year.

a) What size solar array rated in KW would generate your annual electrical usage?

b) The solar irradiance is 1 KW/m2 and you buy solar panels that are 19% eﬃcient. How many square meters of your roof will the solar panels cover?

c) A current rule of thumb is that the full solar installation costs approximately $1.75 per watt after accounting for tax incentives. How much does your solar system cost to install?

d) You pay 10 cents per KWH of energy that you use. How much of your investment do you recover each year in lower utility bills and how many years until your solar power system has paid for itself?

A simple steam power cycle uses solar energy for the heat input. Water in the cycle enters the pump as a saturated liquid at 40°C, and is pumped to 2 bar. It then evaporates in the boiler at this pressure, and enters the turbine as saturated vapour. At the turbine exhaust the conditions are 40°C and 10% moisture. The flow rate is 150 kg/h. Determine (a) the turbine isentropic efficiency, (b) the net work output (c) the cycle efficiency, and...
