Summary
In
the first survey of 2009, Solarbuzz surveyed 1,023 online
inverter retail prices in to its inverter price database,
up marginally from last month's 1,008 price points.
The
January result showed more price activity than December,
but it still not at particularly high levels by historical
standards.
There
were 9 price decreases and 27 price increases this month.
In the previous month, there had been 8 price decreases
compared to 12 increases.
The
US index was up marginally this month.
The
All Inverter Index (see right) includes the full basket
of Inverters on the worldwide survey represented in US dollars
and European, Euros. Further segmentation of this data can
be accessed through our consultancy
services.
The Price Index (see right) is based on Prices per Continuous
Watt - which is a measure of the output power of Inverters.
The larger the Continuous Watt, the larger the power of
the Inverter.
The same calculation methodology applies to this Index as
the Solar Module index - i.e. it is based on the purchase
price for a single Inverter. The
main difference in methodology between this Index and the
Solar Module Index is that all global inverter prices are
aggregated in to a single Index. Those aggregated products
are then simply translated from the local currency in to
either US dollars or European euros.
This
month, the dollar weakened against the euro. As a result,
euro index was down to 0.518
per continuous watt.
The mix of Inverter Retailers is still dominated by US Retailers.
Around 90% of the prices are quoted in US dollars.
