A roof mountable photovoltaic system, wherein electrical energy is transferred from multiple direct current generating sources to at least one wireless energy receiver device through some separated distance. The system is configured such that electrical energy can be transferred even through an obstruction, such as several layers of roofing material, to the wireless energy receiver device. In some embodiments, there are fewer wireless energy receiver devices than the direct current generating sources. In some embodiments, the wireless energy receiver device can include one or more inductive windings, antennae, or a combination thereof, which can couple with the windings, antennae, or a combination thereof of the wireless transmitter(s) to transfer electrical energy from the transmitters to the one or more receivers without direct electrical or physical connection.

An apparatus may determine a parameter related to a voltage value at a midpoint terminal of a system power device, and may adjust a voltage applied to a second terminal of the system power device based on the parameter and a reference value. The second terminal may be different from the midpoint terminal.

Solar tracker systems include a torque tube, a column supporting the torque tube, a solar panel connected to the torque tube, and a damper assembly. The damper assembly includes a first end pivotably connected to the torque tube and a second end pivotably connected to the column. The damper assembly further includes an outer shell, a piston within and moveable relative to the outer shell, a first chamber wall and a second chamber wall within the outer shell at least partially defining a chamber, and a valve within the chamber. The valve includes a first axial end defining a slot and is biased to a first position within the chamber in which the first axial end is spaced from the first chamber wall. The valve is moveable within the chamber from the first position to a second position to passively change a flow resistance of the damper assembly.
