Transcript of PV System Design

Calculating The Insolation
Then The State of charge for the battery Is calculated for each day.
This Data is then Plotted
And the User Is Provided With Summary
The program is a Matlab based function that uses the specification for stand alone solar combined with load data and daily insolation data to model system performance.

PV System Design for a Home on

Block Diagram
Why???
Capital Cost = \$PV Panel + \$Battery + \$Inverter + \$Regulator
= \$289 * 48 + \$15,576 + \$1,169.85 + \$4,159.58 = \$34,777.43
Operational and Maintenance Cost Solar PV = 48 * 250W = 12kW, O&M = \$6/kW-yr * 12kW = \$72/yr
Just A Bit of Background Information
Example:
Population: Approximately 360 People
The island currently runs on 3 300kW diesel generators
64,000L of diesel fuel stored underground with fortnightly deliveries by ship
Diesel costs are expensive
-\$1.70/L which makes electricity pricey
Regulators
Lord Howe Island Hybrid Renewable Energy System
.... SO WHAT ARE WE DOING?
Proposed in July 2014
Project adds 1MW renewable energy systems
- 450kW Solar PV
- 550kW Wind Power
- 400kW Battery Storage

Power entire island by 70% renewable energy by 2018

Designing a standalone system for a standard 4 person home
We wanted a project close to a real life situation
With all the possible challenges
Lord Howe Island - 196.5 rainy days per year
Location and inaccessibility
Life Cycle Cost & Levelised Cost
Average Interest = 5.24%(1994-2014)
Average Diesel Electricity Cost = 39C/kWh
FV of Capital Cost = \$34,777.43 * (1+ 0.0524)^25 = -\$124,686
FV of Battery Cost = -\$85,483
FV of Saving Cost - O&M Cost = \$99,464
Total Life Cycle Profit = -\$110,705

Levelised Cost = \$2.177/kWh
\$34,777.43

\$15,576
\$72
\$2088
