I am a Liquidator and Consolidator for the solar power industry. I work with several large solar contractors & developers, which buy many megawatts of solar equipment every year and get very good pricing direct from the manufacturers.
I also find contractors and other companies that got stuck with some solar equipment due to cancelled jobs, bankruptcies or other issues, and want to liquidate their stock.
I sell this equipment to Contractors & Do-It-Yourselfers at very aggressive pricing.
The brands & sizes available may vary some from one month to month, depending on who purchased megawatts of what that month....but the price will tend to be 5 to 25 cents a watt below the current wholesale market for that same panel.
I will put you in direct contact with the large solar developer-contractor that has the panels you want, at a better-than-average price.
I also now work as a factory-direct manufacturer's rep for a few different solar brands, including Bosch Solar, Grape Solar, Envision Green Tech, Next Generation Energy, OSM Solarform, Zilla racking, and SunDrum.
