You are a Consultant at a reputable De Montfort University spin-off company that specialises in renewable energy solutions. Your client is a multinational property developer on the verge of moving into the UK property market. They are looking to build an estate of 50 new 3-bedroom homes, each for a family of two adults and two children. Each home is gable-roofed with each side of the roof being an 8m by 4m rectangle. Your client has no specific location in mind but is looking to meet all or part of the estate’s electricity needs through photovoltaic energy generation, if economically viable.
Based on photovoltaic energy generation potential alone, choose a suitable location (longitude and latitude) for the estate. Using an appropriately annotated map, justify your choice.
Using the “Load Analysis” sheet of PvSA (the Photovoltaic (PV) system modelling tool developed for this course) and the household appliance power ratings published by the Centre for Sustainable Energy (CSE) (available at:, develop the summer and winter load profiles for one home. You should select between 5 and 15 appliances from the list provided by CSE, for an annual demand in the range 3000 – 4300 kWh. You can adopt a realistic consumption profile of your choice and assume the summer and winter consumption profiles are similar to the autumn and spring consumption profiles, respectively. Provide the following in your report:
Your final summer and winter load tables.
The seasonal load summary table, showing the average daily daytime and night-time consumption and peak load for each season, as calculated by PvSA.
The annual load summary table, showing the average daily consumption and peak load.
Summary plots for the average daily consumption and peak load.

For the home in Task 2, design the most economical rooftop PV system that covers both sides of the roof of the house and assess its economic viability for a 30-year period. You can use the optimal azimuth angle for the location but the slope is restricted to the range . Assuming a grid-connected system on a grid electricity tariff of 15 p/kWh and an annual tariff inflation rate of 2.6%:
Is your proposed investment financially viable?
How much of the home’s electricity demand is met by the system?
What are the maximum and actual capacity factors of the system?
How much CO2 is saved annually? Use the average carbon intensity in December 2020 for your chosen location and assume that the carbon intensity of electricity generated from PV systems is 85 gCO2/kWh. The carbon intensity of grid electricity consumed from any region of the UK can be obtained from the Carbon Intensity API.

This task would require you to use all the sheets of the Workbook but the “PPA Analysis” sheet.
As an alternative to rooftop solar, design and analyse a single solar farm that is capable of satisfying 10% of the estate’s total electricity demand over a 30-year period; determining its total investment cost, net present value, and total customer savings over this period. For the purpose of this assessment, the solar farm is installed on a nearby level field, and, therefore could be of an orientation of your choice. The solar farm is operated by an Independent Power Producer (IPP). Therefore, when selecting the slope and azimuth angles for your system, do bear in mind that the goal of an IPP is profit maximization. Repeat your analysis for 20%, 30%, 40% up to 100% of the total estate demand and plot the graphs of total investment, net present value, and total customer savings over the 30-year period versus the percentage of estate demand satisfied. Proffer a suitable explanation for the trend portrayed by these graphs. Assume the following:
The Power Purchasing Agreement (PPA) between the estate and the IPP is such that if the IPP cannot satisfy the demand it is contracted to supply, it pays a penalty that is the difference between the PPA tariff and the grid electricity tariff for each kWh not supplied.
The same demand profile for all 50 homes on the estate.
The IPP charges the estate 12.75 p/kWh consumed, increasing by 1.5% annually.
By considering the demand side, discuss how the consumption profile of the estate can be modified to further reduce the cost of the system you designed in Task 3, without reducing its total annual energy demand.
Based on your findings in Tasks 3 and 4, suggest the most economical option to power the estate.
Prepare an assessment report for your client outlining your findings. Your report should clearly and logically summarise the outcomes of Tasks 1 to 6 with sufficient information to justify your findings and recommendations. Also detail the steps, as well as any assumptions used to obtain these findings, in order to allow your client to assess their appropriateness. Note that the spreadsheet itself cannot be submitted; all Information must be in the report.
Additional Information
Use PvSA, the PV system modelling tool developed for this course, to design and analyse your systems. Use the rates provided in Table 1 and the current Feed-In Tariff rates published by Ofgem. For PV module, inverter, and battery costs, see the “Material Cost” sheet of PvSA. Assume the following:
A one-off installation cost of £600/kW of installed PV capacity, an annual O&M cost of 6p/W of PV capacity, and an annual battery storage maintenance cost of £50/kWh of storage.
All investments are initially funded through a loan spread over the life of the project.
2% cable losses and no near shading.

It is impossible for any two systems to have the same coordinates and load profiles, and therefore, the same techno-economic indicators. Any two systems deemed to be the same will be flagged as an Academic Practice Offense.
Report Format
The report must not be longer than 1500 words in total, including the title page and references, and there should be no appendices. Use a style appropriate to a technical report (i.e.  formal, factual and to the point).  Use portrait A4 format with a single columnandinclude page numbers in the footer. You should use Calibri or Times New Roman with font of size no less than 11 points. Your report must include the following (including your own headings), in the order depicted:
Title page (include your name, course code, module name, month and year of submission)
Executive summary (150 words max.)
Introduction (250 words max.)
[your chosen headings]
Conclusions (400 words max.)
References (no more than 10 references)
You do not need a table of contents, list of figures, or list of tables.  All tables and figures must be numbered as they appear (e.g., Table 1, Table 2, Fig. 1, Fig. 2 etc.) and referred to in the text.  It is best to do this in Word using ‘insert caption’ and ‘insert cross reference’ when referring to these in the text, from the References tab. Tables must be editable and not images and the “Conclusions” should summarise your findings and recommendations.
A lot of references are not expected, nor is a literature review, but you should include some to support your arguments, data, and assumptions.  These should be reliable sources such as books, reports by respected organisations, and refereed papers.  You may cite lessons from the course; give author as DMU.  For this assignment do not use commercial sites, blogs, press articles, etc.  Use the Harvard (author (year)) or IEEE system [number] for references (in Word you can use Endnotes for IEEE).  Advice is available from the DMU library web pages1.  You should submit as a PDF file (in Word: Save As PDF).  Check the final PDF version for errors, as these occasionally occur in the conversion process.  Note that fields are updated when saving to PDF and this can produce unexpected results.
