Homework Answers
Ans:
PV System=5 KW
Total System Cost =$18000
Tax Credit=30% of Total Cost=0.3*18000=$5400
Electricity Cost=0.35$/KWH
Capacity Factor=0.18
Energy Consumed Per Year=5KW*0.18*8760
=7884 KWH
Value of Electricity=7884 KWH*0.35$/KWH=$2759.40
Net Cost=System Price-Tax Credit
=$18000-$5400=$12,600
Pay Back Period=Net Cost/Value of Electricity Per year
=12,600/2759.4=4.56=5 Years Approximately
Note:
**8760=24 Hours Per day * 365 Days
We are considering per Year

Need helps on parts B, C, E,and F Costs of installing rooftop solar PV : Calculate out-of-pocket costs and payback time for a rooftop solar installation. Assume that this PV system measures 6 m x 5 m and that the panels are 20% efficient. (a) Peak power rating: The solar industry describes the “peak wattage” of a PV system as its power output at a hypothetical, industry-standard irradiance of 1000 W/m2. What would be the peak wattage (in W) of...

4. For an energy source with constant energy production and no operating cost, the levelized cost of energy (LCOE) per kilowatt hour (kWh) can be calculated as: annualized capital cost annual kWh production The annualized capital cost is like a mortgage payment, an annual cost that includes paying both the principle and interest (or opportunity cost of capital) over the life of a project. This can be calculated as: Annualized capital cost = K where K is the capital cost,...

(7 pts) You are installing a 6-kW photovoltalc system that is expected to generate an average of 12,000 kWh per year for 25 years. The system will cost $3.80/Watt to install, then you receive a Federal Residential Renewable Energy Tax Credit for 30% of the installation cost. Your only additional cost over the system life will be to replace the inverter once for $2.500. How much will the solar-generated electricity cost over the life of the system measured in S/kWh?...

20. A 3,000 sqft home located outside of Alamosa, CO has 5 Ton Geothermal System with vertical loop field that costs %20,000. 1600 gallons of propane on average was used before to heat the home per winter over the past 5 years. Geothermal replaced both propane furnace and central air conditioner. It also preheats hot water. They no longer purchase a fuel to heat the home. This new system increased electricity use by around 4,000 kwh annually. The price of...
