Jean Pierre Clejan IGSHPA, NABCEP (516) 625-6880 x 103 www.GreenLogic.com Commercial Solar Power Solutions A presentation to the HIA
2
Outline What is PV? Benefits Installation options Financial case study
3
What is Solar Electricity (PV) ? PV effect converts sunlight into electricity Solar power replaces some of LIPA power Systems are roof or ground-mounted Super-reliable – 30+ year life, no moving parts
4
Ballasted mount over flat roof
5
Benefits of installing a PV system Lowers long-term operating costs Adds value to property / represents solid investment Demonstrates ‘green’ commitment Reduces fossil fuel use / slows global warming
6
Curved solar carport
7
What makes HIA ideal for solar PV? High LIPA rates, rising with fuel prices Good solar exposure and incentives Large number of sizable commercial roofs Many LIPA “Rate 281” customers
8
Available Commercial PV incentives LIPA rebate (going away over time) 30% Federal Tax Credit Accelerated Depreciation Moratorium on property tax increase
9
Ground-mounted system
10
Suitability for commercial solar electricity Good condition roof (or prepared to replace) Facing South, East, West or flat with no shadows Able to make up-front investment Have tax liability to leverage incentives
11
Installation over existing carports
12
Commercial PV Solutions Solar panels clamped onto metal roofs Ballasted systems on flat roofs Laminated systems for metal and flat roofs Building integrated systems (BIPV)
13
S-5! Clamps installed over metal roof
14
10KW clamp-on metal roof installation
15
10KW attached metal roof installation
16
Ballasted systems Solar panels are held down by gravity Requires adequate structure Low tilt angles work best with 120 MPH wind code Normally do not require penetrations
17
Ballasted 10KW commercial flat roof system
18
Ballasted 15KW commercial flat roof system
19
Laminated systems Becomes part of roof Does not add significant weight Very durable and impact resistant Requires compatible roofing system
20
Laminated system on metal roof
21
Laminates over white rubber (EPDM) Gluckman-Mayner design by Men-At-Work construction
22
Building integrated systems The PV system is the roof Provides daylight in some cases Makes visible statement Good for canopies, awnings, sunrooms, skylights
