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

Ballasted mount over flat roof

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

Curved solar carport

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

Available Commercial PV incentives

LIPA rebate (going away over time)

30% Federal Tax Credit

Accelerated Depreciation

Moratorium on property tax increase

Ground-mounted system

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

Installation over existing carports

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)

S-5! Clamps installed over metal roof

10KW clamp-on metal roof installation

10KW attached metal roof installation

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

Ballasted 10KW commercial flat roof system

Ballasted 15KW commercial flat roof system

Laminated systems

Becomes part of roof

Does not add significant weight

Very durable and impact resistant

Requires compatible roofing system

Laminated system on metal roof

Laminates over white rubber (EPDM)

Gluckman-Mayner design by Men-At-Work construction

Building integrated systems

The PV system is the roof

Provides daylight in some cases

Makes visible statement

Good for canopies, awnings, sunrooms, skylights
