Provided herein are exemplary embodiments of an efficient pump apparatus. In one embodiment the pump apparatus comprises a piston assembly loosely disposed within a cylinder. The piston assembly includes a driving cable connecting a top leaky piston and a bottom leaky piston having a check valve connected thereto. The cylinder includes an outlet pipe at an upper portion thereof and a check valve located at a lower end of the cylinder. The pistons move in the cylinder at a velocity relative to the conduit such that as the pistons move along the cylinder they create a substantial tortuous leak path forming a hydrodynamic seal between the pistons and the cylinder.

In one embodiment, the present invention includes a roof support apparatus which may be used for securing a load to a tile-covered roof. The roof support apparatus comprises a mounting plate, a first and second attachment member, an upper support member, and a load. The mounting plate engages its base with an upper surface of the roof. A track of the mounting plate extends parallel to the base and has a width less than a width of said base. The first and second attachment members are adapted to extend downward through an exposed surface of the base on both sides of the track. The upper support member is adapted to pass vertically upward through an opening in a roof covering material, such as tile, and engage a screw which may slide along the tack until the screw and the upper support member are fully engaged.

A centralized server managed by an employer receives reports of renewable energy generation from many remote generation sites belonging to its employees, and then summarizes and details the generation for certification by a certifying standards process. Renewable energy power generation monitors are placed at independent remote locations owned by the employees that collectively report to the server any fractional units of renewable energy power generation represented in aggregate by particular REC's traded on the e-trading platform. And, an ad-hoc sellers consortium automatically aggregates fractional and small units of REC's into marketable lots according to individual preferences of participating small sellers, and the marketable lots of REC's are offered for sale on the e-trading platform.

Provided are easy-to-install rooftop photovoltaic systems. One rooftop photovoltaic system includes a roofing material piece, a photovoltaic module disposed on the roofing material piece and an inverter configured to convert DC from the photovoltaic module into AC. Another rooftop photovoltaic system includes at least one active unit including one or more photovoltaic modules each including photovoltaic cells shaped as shingles to provide a roofing material appearance; and one or more inactive units having the roofing material appearance.

A sales method provides for the demonstration, performance forecasting, financing, leasing, renting, power purchase agreement, tax-advantages, and group benefits of complete renewable energy systems. Even before a sales call is attempted, a system integrator has arranged a special group of lenders and investors that will fund any project initiated, has engaged credit services to check consumer credit files, has collected operational data from a number of its own systems, has created forecast models of performance, and arranged open-membership groups to which a new user can join immediately to share in collective bargaining with utilities, spread down-time risk and expense, utilize tax incentives, etc.

A renewable energy certificate business model embodiment of the present invention accumulates small shares of qualifying energy produced by many small solar installations into the minimum unit sizes that can be certified, traded and sold. Renewable energy generation and load control monitors are installed at hundreds and thousands of small installations to automatically report to centralized servers. These servers log and certify the production of renewable energy into the lot sizes needed for an efficient market. A system integrator provides the brokerage mechanisms needed for buyers and sellers to trade quickly and easily. In one aspect, an online auction website is constructed and maintained on the Internet as a centralized clearing house. The system integrator backs the quality of the lots and the trades with their large enterprise reputation and credit worthiness. The trading can be in renewable energy portfolios, emission offsets, carbon dioxide offsets, and other environmental attributes.
摘要:
Energy services business methods gather up many small pieces of renewable energy generation, energy efficiency, and controllable energy demand reductions en a grid, and present all that in a unified interface to a power utility. The individual constituents benefit from collective bargaining with, a large utility, and can receive energy discounts, rebates, and bonuses for their participation.

A photovoltaic module includes a first photovoltaic cell, a second photovoltaic cell, and a collector-connector which is configured to collect current from the first photovoltaic cell and to electrically connect the first photovoltaic cell with the second photovoltaic cell. The collector-connector may include an electrically insulating carrier and at least one electrical conductor which electrically connects the first photovoltaic cell to the second photovoltaic cell.
