Rocking solar panel sun tracking mounting system

A solar power collection system comprising:

• a photovoltaic (PV) panel assembly comprising:
• a PV panel comprising PV cells;
• and
• a single axis or dual axis tracker frame attached to at least one row of PV panels;
• having a base attached to the row of PV panels and comprising at least one curved rocker surface that presents a first convex surface in at least a first direction to a fixed substrate and wherein the at least one curved rocker surface has a point of contact with the fixed substrate that changes with respect to the fixed substrate, the base positionable on the fixed substrate with the first direction aligned with an east-west orientation, wherein at least one curved rocker surface with a moving axis supports the weight of the panels, and allows the entire single axis or dual axis tracker frame to rock from east to west, tracking the sun while avoiding the need for pillars or a frame to support a fixed axis or hinge;
• a tracker drive unit mechanically coupled to the base via a selected one of:
• (i) a drive rod;
• (ii) a closed loop cable;
• (iii) a torsion mechanism to impart a selected amount of rolling-rocking movement of the single axis or dual axis tracker frame across the fixed substrate, which allows the system to follow the sun from morning to night by adjusting the rocking and moving axis of rotation, thus avoiding slip friction with a fixed rotation axis and withstanding adverse forces such as wind.
