Executive Summary Provide a brief summary of the key methods and key results, max 500 words.
1. Introduction (aims and objectives and brief description of the system studied and methods of the next sections) approximately half a page
2. Solar irradiation analysis
Provide location and data used.
Provide hourly GHI, DNI, DHI, Dry bulb temperature plots and their brief description also using formula. Determine the Daily solar irradiation for each month for the GHI and Global irradiation on a tilted surface. Refer to the brief for key figures. Provide explanations of the method to derive the daily irradiation on a tilted surface. Use correct units.
Provide a final table of the daily global irradiation for each month, which will be used for sizing the system. Determine the design month based on irradiation. Exemplary calculations not necessary.
PV System Design and Energy Analysis for Residential Use
3. Household daily electricity needs based on appliances available
Determine household daily energy demand based on energy bill or other sources for the specific location and by analysing the appliance power. Differentiate Seasons. Provide tables. Determine the monthly energy demand and provide a table which is a SAM input. Provide a graph of the hourly load as derived from SAM. Provide descriptions of tables and graphs. Determine the design energy demand.
4. Components selection of the PV systems
Provide the main characteristics of each component selected necessary to do the sizing of the system. Please refer to learning material for the key characteristics (e.g. Isc, Voc, Vdc, Vcc, ect). Data sheet can be placed in the Appendix. If the components are from SAM there is no need of data sheet, as far as details are provided in Tables.
4.1 PV modules
4.2 Inverter
4.3 Battery
5. System sizing: how many modules in series and in parallel, total capacity.
Provide details of how many modules are wired using the provided formula for determining the number of strings and parallel strings.
Provide the area of the PV array and layout. Specify DC/AC ratio from SAM.
6. Using SAM provide the electricity produced by the systems on an average day during each month, total energy produced in one year and capacity factor.
Provide a graph showing the monthly energy production and the loads.
Provide graphs showing the Time Profile of an average day of the year of your PV plus battery Power dispatch to the household (figure 10 of Brief) and Time Profile over the year (zoom on the first days of January) of the energy sold to grid, to load and imported from the grid. Determine from the data the total annual energy sold to grid, to load and imported from grid. This will be used for economics.
7. Economics
7.1 Evaluation of costs: Components, Maintenance, Installation, future foreseeable lump costs during the project.
Determine the cost of each component in a Table and annual maintenance. You can also refer to NREL Annual Technology Baseline (ATB) costs for roof top PV residential $/kW installed.
7.2 Evaluation of savings. Based on saved cost of grid electricity, income based on electricity ratings for the energy produced more than the household needs, cost of extra energy from grid. Consider different cost of selling and buying based on realistic ratings.
7.3 Estimate of Present worth, internal rate of return, discounted payback period. Determine the levelized cost of electricity for your system.
Provide graphs and Tables for PW and IRR.
8. Conclusions and recommendations
Draw conclusions on your design and financial viability, compare LCOE with typical residential ones from literature. Provide recommendation on this study on how it could be improved or alternatively motivate why it is a good design.
9. References (provide references, use consistent style, Harvard style preferred.).
