A modular solar concentrator having an aspherical primary reflector that is a segment of a paraboloid parent shape. The peripheral shape of the segment is selected to allow arrangement of an array of concentrators in a closely-fitting pattern. The peripheral shape may be rectilinear or trapezoidal. The primary reflector may be an off-axis segment having an optical axis at or near a peripheral edge. In one embodiment, the modular solar concentrator includes a primary mirror and a secondary minor. In an alternative embodiment, the modular solar concentrator is monolithic having internal surfaces that reflect light into the optical fiber. The monolithic concentrator may include a first internal surface that functions in a manner analogous to a primary mirror and a second internal surface that functions in a manner analogous to a secondary mirror. The optical fiber may be secured in the monolith by an index matching adhesive.
