NOVELTY - A solar farm comprises several replaceable solar cell panels adapted to convert sunlight into electrical power. The panels comprise solar cells having energy conversion efficiency of less than or equal to 13 (preferably less than or equal to 7)% and a lifetime (T50) of less than or equal to 15 (preferably less than or equal to 1) years. The solar farm has a solar farm area of greater than or equal to 500 (preferably greater than or equal to 10000) square meters. The solar farm has capacity for yearly production of at least 50 (preferably at least 2000) Mwh.    USE - As a solar farm useful in a solar cell system (claimed) for converting sunlight into electrical power.    ADVANTAGE - The solar farm has a solar farm area of greater than or equal to 500 (preferably greater than or equal to 10000) square meters. The solar farm has capacity for yearly production of at least 50 (preferably at least 2000) Mwh. The solar farms comprise solar panels and solar cells that are low cost and easily replaceable. The solar farm provides improved economic recovery of investment. )The solar farm can be built for large scale power production with large area modules. The panel is adapted to be easily, efficiently, and economically replaceable. The panel can be disposable in that it structurally is built to be replaced although it is stable enough to be used until in need of replacement. The solar frame and power block can be adapted to enable low cost removal and insertion or connection of the low cost replacement. The manual replacement can be used without need for complicated or expensive or difficult to use tools.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) method of making a solar farm involving manufacturing several replaceable solar cell panels adapted to covert sunlight into electrical power;    (2) method involving providing several replaceable solar cell panels adapted to convert sunlight into electrical power, exposing the solar cell panels to sunlight, and replacing the solar cell panels with additional replaceable solar cell panels; and    (3) a system comprising several replaceable solar cell panels adapted to convert sunlight into electrical power, where the solar cell panels are adapted to function as a solar farm.
