Using our mathematical investigation skills, lets’ find the facts. In this investigation, we will be considering the purchase of a 1.5kWH solar panel system fully installed for an average cost of $8000 (note; there may be many more additional costs to consider during installations of solar panel systems that we will not consider in this investigation).
1st Challenge
1. Open this link to the Clean Energy Council consumer guide . Find the statistics which claim the average daily production rate of kilowatts for the closest possible area of South East Queensland.
2. Using the same link, find the average daily household consumption in kW.
3. Write the formula to find the percentage you are saving per day? Solve this question.
2nd Challenge
1. The Queensland Government encourages the use of clean energy and offers a bonus for all that use this solar technology scheme. Search the consumer guide link provided to find out how much money the government will subsidise from the total installation costs. Follow these steps;
A) Find the total amount of small technology certificate (STC’s) currency you are entitled to in your area (known as credits).
B) Find how much you can multiply these credits by between the years of 1st July 2011 to 30th June 2012.
C) The government will subsidise $40 for every credit.
2. Write a new equation which states the steps in A, B, and C, and the total subsidy from the total installation cost. Solve this problem.
3rd Challenge
Let’s consider the total government subsidy taken from the total instillation cost as a new total instillation cost for the following problem.
1. The 1st challenge identified how much kWH percentage is being saved from the daily consumption when using a 1.5kWH solar panel system. Open this link to Origin Energy and search for the cost of kWH for the domestic residential tariff which includes GST. Using your saved daily kWH from your solar panel system, work out how much you are saving daily.
2. How long will it take for these savings to finally pay of the new total instillation cost? Write the formula and solve (note# 2012 is a leap year and every following fourth year, example 2016 is another leap year).
3. If the new instillation was installed on the 18th of December 2011, what date would it be totally paid off when just considering what is being saved on the bill?
Final Challenge
1. To get the best kilowatt saving value out of your Solar Panel System, you need to find an optimal angle of, tilt and direction. Open this link and find what is best for people living in Australia.
2. If the angle of your roof is congruent with the best suggested angle of instillation. Then what angle would the roof be on?
3. Now it is time to evaluate the statistical reports and claims represented by media and other places. List or link the resource you are referring to and compare or justify your answers. For example, do the claims seen on TV and elsewhere still stand true after you have made your own calculations?
