Solar Module Price Highlights:   October 2008



Price Summary

The tracking of online retail module prices continues. This is now the fifth month in a row where the number of price increases in the survey has exceeded the number of decreases. This outcome has been influenced by a significant number of upward price adjustments from one European retailer, absent that the number of price increases and decreases this month would have been similar.

Sales of modules through online retailers is a relatively small channel in volume terms, when compared with other channels to market. Most modules are, infact, sold by module manufacturers to wholesalers or what is called in the industry, "system integrators", who package the modules up with other components to make a "PV system". It is the PV system that is usually purchased by the end consumer.

The benefit, though, of the online survey is that is allows a significant number of prices to be monitored on an "apples to apples" comparison, in an objective manner. The survey results are, of course, only as good as the accuracy of the online data, noting that not all retailers may keep their pricing fully up to date. Alternatively, the actual price paid may, on occasion, be different that actually displayed. In addition, modules are usually purchased in multiple units, whereas this survey only displays pricing for a single module. That methodology has been chosen because it facilitates the "apples to apples" comparison.

Sometimes, Solarbuzz is contacted to ask why a particular price has not changed for a long period of time. The answer is always, that's what the survey data shows! Quite deliberately, Solarbuzz does not overview or second guess the raw data for the purposes of the indices on this page.

This survey has proven to be a useful market for Solarbuzz research analysis since it started in 2001. However it is never be utilized in isolation of other research methodologies - it is just one reference point for what is happening in the market.

Returning to this particular month's result, from a survey of 1,534 online retail prices, there were 45 price increases and 21 price decreases. This compares with the September result where there were 38 price increases compared to 16 price decreases.

These results left the US index unchanged at $4.85 per watt while the European index was up 3 euro cents at €4.72 per watt. The other notable effect during the quarter was a significant strengthening in the dollar against the Euro, albeit this effect only indirectly impacts the results.


Lowest Prices ($/Wp)

The tracking of the lowest price band in the survey is measured against the number of prices below $4.75 per watt.

As of October 2008, there are currently 233 solar module prices below $4.75 per watt (€3.42 per watt) or 15.2% of the total survey. This compares with 197 prices below $4.75 per watt in September. The lowest retail price for a multicrystalline solar module is $4.26 per watt (€2.90 per watt) from a US retailer. The lowest retail price for a monocrystalline module is $4.30 per watt (€2.92 per watt), also from a US retailer.

The lowest thin film module price is at $3.27 per watt (€2.35 per watt) from a Germany based retailer. As a general rule, it is typical to expect thin film modules to be at a price discount to crystalline silicon (for like module powers). This thin film price is represented by a 60 watt module.

Note once again, that these prices are based upon the purchase of a single solar module and prices are exclusive of sales taxes. Information on volume discounts, factory gate and PV system pricing is available as part of our consultancy services.


Price Index Context

The module cost represents around 50 - 60% of the total installed cost of a Solar Energy System. Therefore the solar module pric
e is the key element in the total price of an installed solar system. All prices are exclusive of sales taxes, which depending on the country or region can add 8-20% to the prices, with generally highest sales tax rates in Europe.

Note: As a guide, the industry is looking to drive module prices down to $1.5-2Watt over the next decade, if it is to make large inroads in to the grid tied electricity market, without subsidy.

The All Module Index is volume weighted to take account of the fact that the majority of market demand (in Megawatt terms) occurs in the high power module segment.

Note: Price changes (in US dollar terms) caused only by an exchange rate movement, do not count as a price change in the above table. i.e. there has to be a movement in the local currency in question to register a change.

Our survey also tracks average prices by power segment analyzed by 125 watts and above, 40 - <125 watts and <40 watt modules. These price differentials can vary with market demand and manufacturing mix. Lowest prices per Watt can be found in the 125 watts and above segment, as manufacturers can minimize their unit (per watt) manufacturing cost. This information is available through our consultancy services.

Most Solar Module prices are represented by Companies marketing from the United States and European Countries, which display retail prices on their respective Company web sites. These companies market solar products globally. There is less public display of prices in the key Japanese market. However, the survey does include companies from USA, Germany, United Kingdom, South Africa, Brazil, Mexico, Australia, France, Switzerland, Greece, Korea and Canada. Exchange rate conversions from local currency in to US dollars and Euros are made on the date of each survey.

In order to retain consistency in the data, the prices are based on the purchase of one solar module and are the lowest price displayed on the Internet site for that quantity (sometimes, this price is described as a 'sale price'). Lower prices that are available on multiple purchases are held outside the main index, in order to retain the consistency of the Price Index. Most sales companies offer discounts on multiple unit purchases and some companies offer to match the lowest price of competitors. The prices are exclusive of local taxes.

The typical Solar Industry Marketing structure is when a Solar Module Manufacturer sells to a Wholesaler (also known as "Distributor" or "Value Adding Reseller"), who then sells to a Retailer (also known as "Dealer"), who sells to the public or solar user. Value Adding Resellers often also sell direct to the solar user. In circumstances of a large order, the manufacturers may sell direct to the solar user, usually a commercial or government entity.

The price
represented on the survey is the Retailer price to the public or solar user. There are some rare examples where Wholesalers and even Manufacturers display prices and sell direct to the public on their web sites.
