Patent MarketPlace: Wind Power and Solar Patents for Sale

Lower-Cost Photovoltaic Cell Manufacture (Schwartz): U.S. Patent No. 8,618,411

Solar power has taken off, and solar panel farms and solar panels on rooftops are becoming common sights around the world. As solar companies try to reduce costs, one area of potential cost reduction is to make the manufacturing of the photovoltaic (PV) cells that constitute the solar panels more efficient and less expensive. This is exactly what the invention covered by this patent does! PV cells are currently manufactured upside-down starting with the glass front and ending with the metal back. This Patent turns the process right-side-up so metal foil roll-fed production is possible. The significant reduction in manufacturing cost will make U.S. PV cell OEMs competitive with Asian manufacturers!

U.S. Patent No. 8,618,411 for a “Method of Making Photovoltaic Cell” would be a critical acquisition for any business in the solar power industry. Manufacturers would use the technology directly, while solar panel installers would license it back to their solar panel suppliers.

Wind/Solar Generator (White): U.S. Patent No. 8,269,368

This patent takes both wind and solar power-generation to the next technology. The invention covered by this patent starts with a totally new concept in wind power generation. A conical vortex moves air through the unit with as little interference as possible, reducing heat and improving efficiency. The cowl-housed design addresses many of the problems with the wind turbines of today – height requirements, whoosh noise, bird kills, high maintenance costs, downtime for maintenance, high-wind and low-wind downtime, and limited access to transmission lines – to name just a few. Solar panels provide power when wind speed is too low or too high. In addition, the technology is totally scalable, so units can be manufactured in various sizes and generation capacities.

U.S. Patent No. 8,269,368 for a “Wind and Solar Electric Generator” would be a critical asset for any wind turbine OEM, or any business looking to break into the wind power sector.

Dual Mode Solar Panel Power Management (de Caires): U.S. Patent No. 8,269,374

Solar panel farms and solar panels on rooftops are increasingly more common sights. The real challenge, however, is not installing the solar panels. It is managing the power produced by the solar panels for net metering and other applications. This patent addresses a critical need: Managing the power from a solar or other ecological power source (EPS) and the needs of the building or solar farm owner. This patent covers a dual-mode power management system. During a power outage, the solar or EPS directly charges a battery. When there is power available from the local utility, all solar or EPS power is net-metered to the grid with a small trickle of the utility power going to charge the local battery system, creating maximum grid-feed efficiency.

This patent would be a critical acquisition for any solar power, solar panel installer/systems integrator, electric utility or inverter/controller OEM, giving the acquirer of this patent a strategic competitive advantage!

Zero-Contact Transmission for Wind Generators (Future Force): International Portfolio of Five Wind Power Patents

While renewable power such as wind is low cost, a substantial amount of the energy generated by the wind turbine’s blades is lost to heat and friction in the transfer of power to the electric-generation unit. This international portfolio covers a transmission that uses magnets to dramatically reduce friction and, thereby, also reduce energy loss in the system’s drive chain. The Zero-Contact Transmission covered by this Patent has its most obvious applications in wind power, but it also has applications in any power-generation system that is based on mechanical energy such as hydropower, tidal and wave power, and fossil fuel and trash-burning plants.

Pre- and Post-Construction Electric Meter (Southern Company): Technology/Know-How

For the last 100 years, the practice has been the same. When construction is started on a residential, commercial or other structure, a temporary electric meter is installed to provide power to the general contractor and the sub-contractors working on the structure. As the structure nears completion, a permanent electric meter is installed on an exterior wall of the new structure, and once all construction is finished, the temporary electric meter is removed.

The technology and know-how covered by this property eliminates the time, money, disruption and general aggravation of installing a temporary electric meter, then installing a permanent electric meter, and then removing the temporary meter. The technology covers the use of a single underground electric meter pedestal that serves the needs of the contractors working on the structure, and the same meter is kept in place and used by the owner or tenant of the new building. The inventor has over 100 such units in place, so the concept is not theoretical, and working prototypes are available.

For any manufacturer of electric metering equipment, the technology and know-how described here can be developed into a next-generation line of electric metering equipment, giving the owner of this technology a distinct competitive advantage over its competitors.
