Design of an electric 12V DC motion regulator, LED light and solar power

The goal is to provide economical electricity generation and storage as well as an electrically operated valve controller and LED light with a motion detector. The parts should be ready-made components from companies such as AliExpress or IndiaMART. The system components work 12V DC and are as follows: - Solar cell with wall mount - Battery and controller - valve regulator (power may be about 2-5 W) - LED light, (power may be about 2 W) - motion regulator of the valve The solar cell is used between the Earth's 45 ° latitudes, so there is usually enough light. The battery should be easy to use (eg AGM or lead-acid battery). There should be enough power for 2 days without additional charge. A suitable controller for the power system should be included. Motion regulator of the valve. The distance between the fixing lugs of the straight push rod of the valve regulator in the closed position, is 210 mm and in the open position, about 250 to 310 mm. When the push-button of the power switch is held pressed, the rod in the closed position of the controller will automatically extend to another extreme position (the open position) for about 1-2 seconds and stay there. When the power switch is released, the controller automatically returns to the close position and stays there. Turning on the power is done by a push-button attached to a 10 mm thick plate. The force to resist the movement of the regulator is about 5 to 10 kp (50 to 100 N), as well as the force that aspires away from the end positions. The controller should be moisture resistant. The power is switched on and put off about 25 to 50 times a day. The light should be a splash-protected LED lamp mounted on the inner wall. The power of the LED light is about 2 W. The light is on for about 2-3 hours a day. The motion regulator of the LED light switches the light on for 3 minutes. It would be good if the motion detector could be integrated into the LED light. The designer should draw up a system diagram of the whole as well as a detailed list of the necessary parts (where to obtain, part names, part numbers, prices).
