Solar Power Plant Design with Underground Light Room

A solar power plant design, shown in FIGS. 1 to 4, wherein sunlight is directed by way of curved arrays of mirrors to an underground “Light Room” 9, which is specially constructed to contain one wall fully covered with PV modules 11;

• two side walls, the floor, the ceiling and the protrusion 12 covered with mirrors 10, and one side wall covered with fans 18 as part of a cooling system;
• wherein the design may use commercially available mirror arrays, PV modules, balance of plant equipment, fans, cooling and grid connection equipment;
• wherein the solar power plant design enables higher efficiency for sunlight to electricity conversion via utilization of different sets of mirrors 5, 6, 10 for multiple sunlight reflections towards PV modules, keeping dust and dirt away from PV module surfaces 11 by generating a positive air pressure inside the Light Room 9, and keeping PV module temperatures low by utilizing fans 18;
• a tracking mechanism 13 may be utilized if chosen;
• wherein the design, if chosen so, also enables easier and cheaper construction by the installation of quick-mount racks for PV modules, lower operation and maintenance costs due to protection of the PV modules from dust, dirt, heavy rain, lightning, snow, storm, sand storm, etc.;
• and
• wherein the design also frees up valuable land that current state-of-the-art solar plants use to generate electricity, which may be utilized for farming, infrastructure or buildings, rural or urban areas, or any other public or private use.

A Light Room, shown in FIG. 4, wherein the light room is built underground with one wall covered with any number of PV modules;

• wherein two side walls, the floor, the ceiling and the protrusion 12 covered with mirrors, one side wall covered with fans 18 as part of a cooling system and a gate 8 to let sunlight in;
• wherein the Light Room 9 design makes it possible to reflect the sunlight that is not absorbed by the PV modules multiple times and direct it back to the PV modules for increased electricity production, as shown in FIG. 2;
• wherein the adjustable rotating flaps 7 of the gate 8 make it possible to pause electricity production by closing the gate in the events of heavy rain, lightning, snow, storm, sand storm, etc;
• a cooling system with fans 18 placed on side wall enables higher sunlight to electricity production efficiency by keeping the temperature of PV modules low, while keeping dust and dirt away from the PV modules by creating a positive differential pressure;
• wherein the cooling system also lowers operation and maintenance costs by keeping the PV module surfaces clean and protecting the PV modules from harm in the events of heavy rain, lightning, snow, storm, sand storm, etc.
