In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by rotating its base around a threaded connection until it locks in place so that a solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. An alternate embodiment of the apparatus is offered to support a rail-less pivot mount as well.

A pump (2) system includes a pump, a sensor (22; 28) arranged in or at a flow path (14), and a concentration measurement device measuring a concentration in liquid inside the flow path (14). The concentration measurement device includes the sensor (22; 28), as a concentration sensor, connected to an evaluation device (26) for evaluating readings of the sensor (22; 28). The evaluation device (26) is connected to a further signal source (20; 24), providing at least one further parameter, and is configured to carry out an evaluation of the reading of the sensor (22; 28), taking into account the further parameter provided by the further signal source (20, 24) to output the concentration in the liquid. A solar heating system includes the pump system.

An autonomous solar module installation platform can be used for solar module installation onto a solar tracker. The autonomous solar module installation platform can include an off-road capable base vehicle and a robotic arm, mounted on the off-road capable base vehicle, for the solar module installation onto the solar tracker.

The off-road capable base vehicle and the robotic arm can communicate with each other and cooperate their movements to proceed to the solar tracker and align with the solar tracker in order for the robotic arm to pick up and lift the solar module during an installation of the solar module onto the solar tracker.

An autonomous solar module installation platform can be used for solar module installation onto a solar tracker. The autonomous solar module installation platform can include an autonomous ground vehicle and a robotic arm for the solar module installation onto the solar tracker. The autonomous ground vehicle can autonomously drive itself to the solar tracker using a global positioning system and align itself with the solar tracker using at least a vision system in order to place one or more solar modules onto the solar tracker.

An exemplary solar selective coating can be provided to be deposited on a substrate. The exemplary solar selective coating can comprise an adhesion layer, an absorber stack comprising at least one absorber layer, and an antireflection stack which can comprise at least one antireflection layer, e.g., all provided in a sandwich configuration. The sandwich configuration can provide the adhesion layer deposited onto the substrate, the absorber stack deposited on the adhesion layer, and the antireflection stack deposited on the absorber stack. The adhesion layer can comprise a metallic layer comprising molybdenum and titanium.

The present invention typically features integrative configurability for transportation/storage, and disintegrative configurability for operation. Two half-cases are coupled to obtain a case. A case is uncoupled to obtain two half-cases. Each half-case houses a solar panel (pivotably connected to the half-case) and a U-bar (pivotably connected to the solar panel). The solar panel is pivoted away from the half-case's interior to the angle-of-inclination desired for collecting solar energy. The U-bar is pivoted away from the solar panel's back to securely fit into one of plural parallel slots provided across the half-case's interior, the U-bar thereby holding the solar panel in place at the desired angle-of-inclination. The half-cases are laid flat individually to collect solar energy. A half-case is compacted by pivoting the U-bar proximate the solar panel's back and pivoting the solar panel proximate the half-case's interior. Two complementary half-cases, each compacted, are (re)attached to form a portable case.
