SANYO’s Corporate Philosophy

SANYO Solar Power Solution

SANYO aims to be a leading provider of clean energy systems and

products. Our vision for a sustainable future involves integration of

our advanced HIT solar technology with personal electric vehicles.

SANYO Solar Overview

• 60 years of electrical product manufacturing expertise.

• Making solar products since 1975.

• We’ve been in business longer than our production warranty.

• 600 MW of production capacity by 2011.

• Vertically integrated module production.

• Premium module with best production density in the world.

• HIT Double—unique in the industry.

SANYO HIT Module Technology

• HIT = Heterojunction with Intrinsic Thin layer

• Superior Temperature Performance– Up to 15% more than standard panels.

• Ultra High Efficiency– 23% cell conversion efficiency; up to 30%

more power per square foot than competitor’s.

• 100% Warranted Power Tolerance– Customers get what they pay for; up to 3% more kWh as a result.

• Low Light Performance– Earlier to rise, later to bed; 1-2% more kWh

• American Jobs– Silicon wafers will be made in Salem, Oregon starting in October

2009; this comprises over 52% of a completed module.

Benefits of Solar Covered Parking• Green branding

– Charging station is visible from a distance.

– Instant connection of EV charging with clean energy in the minds of target customers.

• Attracts customers and tenants with weather protection

– Less heat in the south

– Less snow in the north

– Less rain everywhere

• Energy value of solar electricity. Helps make the case to install a EV charging appliance when that revenue model is still being worked out.

• Extends lithium-ion battery life & performance by lowering battery temperature.

• Alleviates “range anxiety” by putting charging locations into the community.

• LEED credits (SS4.3, SS 7.1, EA 2, IAD)• Reduces vehicle interior temperature—save energy

on cabin cooling.• Lessens UV damage to vehicle.• Optimizes use of land; puts the parking lot to good

use. • Local utility grid stabilization. A distributed

generation component to an EV charging infrastructure initiative will help offset any need on the part of the utility to upgrade transmission infrastructure.

SANYO Solar Charging Canopy Solution

• Complete turnkey solution

• PowerCanopy™-- Kawneerdesigned structure:

– Strong

– Beautiful

– Watertight

– Easy installation at location

• Integrates with any charging appliance network

SANYO Solar Charging System Overview

• Complete Solar Charging Station to promote the launch of plug-in Electric Vehicles to the North American market

• 42 – HIT Double modules (9 kW array)

– Panels generate electricity from both sides—unique in the world of solar

– Highest efficiency & power per square foot commercially available

– Covers 3 standard parking spaces

• 3 Electric Vehicle Charging Ports

• Solar array & charging appliances would be grid-tied & eligible for all current government incentives

• Each space with a SANYO solar canopy will generate more than enough electricity to fully power a year’s worth of EV driving.
