NOVELTY - The method involves retrieving electrical rate data from an electric utility across a network in a server, and analyzing operating data and the electrical rate data on the server to generate electrical power exchange data at the server. The electrical power exchange data is sent from the server to solar power stations (100) across the network, where the solar power stations are selectively connected to an electric utility grid in accordance with the electrical power exchange data.    USE - Method for completing demonstration, performance forecasting, financing, billing, leasing, renting, power purchase agreement, tax-advantages and group benefits of complete renewable energy systems for a resource e.g. coal, oil and natural gas, in industry/business.    ADVANTAGE - The method enables providing a maintenance business model for operational anomalies that indicate trouble or developing problems using remote communications or sending repair crews. The method enables providing a sales business model that provides information to sharpen pricing formulas and product performance forecasts. The method enables providing a performance monitoring business model that is accessible by a user to check on and control own energy production account. The method enables providing a renewably energy certificate business model that accumulates small shares of qualifying energy produced by small solar installations into minimum unit sizes that can be certified, traded and sold. The method enables providing a virtual utility business model that allows individual solar installations to be grouped together into a cooperative or portfolio, thus managing power production, equipment repairs and downtime, incentives and energy contracts as a single entity. The method enables providing a business tuning business model that provides feedback to the operation of a solar energy installation and installer that is useful in tuning for better efficiency and economy. The method enables the business model to salvage the tax-advantages and benefits that are lost by solar installations that are too small or non-qualifying into groups and leaseholds that can be operated on a larger scale to attract better construction and operation capital and qualify for government tax incentives and clean energy programs.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a server computer comprising a memory coupled to a processor.
