We are continuing our series of articles on lowest prices per watt for solar photovoltaic panels where every time we have changes in the price ranking we will publish a new article with corresponding date in the title.

We list the cheapest panels dollar per watt that we can find on the internet and through direct research. We also include listings of products our readers submit to us through or Contact Us form or in the comments. Representatives of the different vendors are welcome to submit info about their products too. Very differently from other “cheapest solar panels lists” out there we will not charge you for that and we will not tell you the list is already full – yep, this is what some publishers of lowest prices in solar have told some of the vendors of realistically the cheapest panels in certain sizes.

We will place in postings like this questions from our readers that we can not get enough info on to answer them completely. We are inviting, as in most of our articles, readers with enough access to information and data to comment and point us to the correct sources.
A reader (whose identity we are not [...]

A specialist from one of the companies distributing and retailing solar panels brought up a question for discussion that is not usually very specifically talked about but was raised by a client of theirs. The client was looking for the most efficient panels in terms of peak power (rated watts) per square foot of the panel (module) the way it was commercially available.

He was not interested to hear about the comparison between the different technologies in particular because they are usually compared on cell level and the data available is usually from scientific lab test not necessarily directly related to the realistic efficiency of the finished panel. When cells are actually implemented in the configuration of the panel there might be numerous factors additionally affecting the power-to-physical-area efficiency of the panel.

We are issuing this quick analysis of the current solar photovoltaic industry and related businesses and we also want to announce some topics we are currently preparing analysis on for you to know what to expect soon from SolarByTheWatt.com (Solar By The Watt Dot Com).

There has been a huge interest to our analysis till now on cost per watt of components (panels, modules etc.) as well as of whole projects and the reflection of that on economic efficiency (return on investment) from solar photovoltaic projects. Such articles include: Price, Dollar Per Watt for Large Solar Photovoltaic Projects , Lowest Solar Panel Prices Per Watt 2009-02-24 and Economics of Solar Power. Our Lowest Solar Panel Prices Per Watt series will continue when we have a good update on the contenders in the top list. Notice that differently from many popular low price listings …
