Introduction
Why solar a system?
Introduction to solar system (basics)
Perform a study to determine if a solar carport project can be technically and economically feasible for WEB.
Renewable source of energy
Reduces dependency of fossil fuels
Reduces CO2 emissions
Increase knowledge on Solar Technology
Improve power production efficiency during peak time demand (daylight hours)
System sizing and location
PV module & inverter selection
Carport Design
System Losses
Tie in Point
Mechanical and Electrical installation
Guarantee Solar Power Output per year
Required Maintenance schedule
Economic evaluation (savings?)
Recommendations
Tasks:
Photovoltaic module
Different types of PV Module
Mono-crystalline silicon
Multi-crystalline (Poly) silicon
Amorphous (Thin film)
Inverter
Grid-tied PV inverters
Micro-inverter
String inverter
Central inverter
Technology Orientation
Important PV Module Criteria
Cost per Watt (direct related to the economic feasibility)
Durability (direct related to the overall performance)
Quality and certification

Carport structure
Assignment: Solar Carport Project
Direct Irradiance
Reflection
Scattering
Diffuse Irradiance
(Direct + Diffuse)
Absorption
Global Horizontal Irradiance (~1200 W/m²)
Three different ways
NREL Data (Satellite)(6.0-6.5 kWh/m2/day)
Calculated Data (6.6 kWh/m2/day)
Weather station (7.2 kWh/m2/day)(4-5 months)
Data acquisition of solar insolation
Location of the parking lots at WEB
Separated into 2 sections:
West section area ~3400 m² (115 parking spaces)
East section area ~2900 m² (100 parking spaces)
12.42 degrees latitude and -69.9 degrees longitude
W.E.B. Aruba N.V.
Aruba
Site analysis
Movement of the sun
Analyzed with: SunTrajectory App.
Welcome
Methodology
Photovoltaic technology orientation
Site analysis and Meteorological Data acquisition
Project component selection
Concept design
Operation and Maintenance (O&M)
Economic analysis
Technology Orientation (cont.)
Extraterrestrial solar irradiance (1324 W/m²)
Manufacture BAJA (2 types evaluated)
Low-cost (0.6 USD/ W)
High-cost (1.0 USD/ W)
Offer a stable network
Reliable energy supplier
Produce power with sustainable energy
W.E.B. Aruba N.V. Vision
Concept Design
Carport structure high 3.8m (fire responders and other services)
East section parking lot
Small switchgear (inverter housing and utilities)
West section parking lot
Larger switchgear (inverter housing, utilities and other loads)
Transformer (480V AC to 12.6 KV for transport)
Tie-in point to Recip unit (12.6 KV Spare Breaker)
Installed Weather station location
Operation and Maintenance (O&M)
Site analysis and Weather data acquisition
Project Component Selection
Project Component Selection (cont.)
System Configurations
Total of 6 configurations analyzed
Top 3 chosen for economic analysis
Monitoring system
PV system grid penetration issue
System Voltage (fluctuations during cloudy periods)
Filtering by inverter but not all
Frequency regulation (regulating devices wear out faster)
Load Scheduling (Generating units on constant standby)
A smart Power Management System is essential!
Forecasting Technology
Better power management and grid stability
Operation
Operation and Maintenance (O&M)(cont.)
Maintenance (2 types)
Concept Design (Cont.)
Preventive Maintenance (P.M.)
Module cleaning (recommended at least 4 times/ year)
Electrical checkup (e.g. loose connections)
Structure checkup (e.g. foundation cracks, rust)
Vegetation control (e.g. grounds keeping)
Corrective Maintenance (C.M.)(important criterias)
Diagnosis
Speed of response
Troubleshooting and repair time
Economic analysis
Conclusions
Recommendations
Solar Carport project technically feasible
Max. installed capacity 584 kW (DC)
Overall DC-to-AC derating after losses 24%
Max. installed capacity 445 kW (AC)
Crystalline PV modules recommended(stability, longevity and durability)
Production more than 1.000 MWh/ year (1% WEB's own consumption)
Estimated cost about USD 2.87/ Watt (min. investment USD 1.6 million)
Power Production cost of solar system about USD 0.16/ kWh
Current payback period 31 years (based on current HFO price)
Savings for WEB is about USD 52.000/ year
Currently not economically feasible
Re-evaluate project if cost of HFO increases above USD 125/ barrel.
Combine other mounting methods into solar project mix.
Explore other financial options to reduce interest rates.
Evaluate larger scale solar project (benefit of economies of scale).
