| Solar
Energy Industry Electricity Prices |
| The
solar electricity index below draws exclusively upon the global
Solar Module prices in our survey in
the high power band exclusively (> 125 Watts). This price segment
was unchanged in May 2008 (vs April 2008). |
| The
May 2008 survey result saw increasing Charge
Controller and Inverter prices and
steady Battery price price indices. |
| The
overall outcome is to move the Solar III index unchanged at 21.29
cents per kWh in May 2008. |
| Solar
Electricity Price Index verses US Electricity tariff Price Index
(US
cents per kilowatt hour) |
| This
table compares Solar Electricity prices (Source: Solarbuzz LLC survey)
with US Government Statistics on US Electric Utility average Revenue
per Kilowatt hour by Sector. The Solarbuzz Solar Electricity Index
is typically updated within 10 working days of the end of each month.
The Solar Electricity Index started in July 2000 and in the most recent
month is based upon a survey of around 80-90 Companies retailing solar
electric products. |
