We have no stranger for solar energy, and the solar street lights on the roadside can be seen everywhere, solar energy has entered daily life and played a huge role. In fact, the source of solar applications is still the idea of engineers. How will you use the solar? Take a look at these programs, have you unable to meet your thoughts!
1, photovoltaic 35W solar tracker with DC motor
The project is intended to be used for educational purposes. It will be used to showcase for the first time to contact solar tracker and photovoltaic power generation. The project relates to renewable energy, especially photovoltaic power generation. A two-axis solar tracker with photovoltaic is designed to follow the sun during the day. Photovoltaic power is powered by solar tracker (no external power supply).

3, solar WiFi meteorological station
The purpose of the project is to make a simple and reliable solar acquisition circuit, and then utilize the circuit to power the weather station, the weather station to monitor the basic weather parameters, such as temperature, pressure, humidity, wind speed / direction, and rainfall. The power acquisition circuit uses a TP 4056 chip. This circuit can be used in any of the application applications of lithium ion batteries.

5, multi-power supply design scheme based on solar energy (schematic + source program + BOM table + demo video)
This design is design and implemented as follows:
Multi-power supply is two power supplies, a solar battery output 12V, a DC lithium battery group; the load is first powered by solar energy, and it is found that the lithium battery pack is powered together (parallel power switch analog quantity in parallel power switch simulation) The allocation current ratio of the two power supplies is adjustable, and two current allocations can be displayed).

6, portable solar camera monitoring system
Sony SPRESENSE development system with integrated GPS and 5 million pixel cameras seems to be ideal for portable monitoring systems. My idea is to build a solar cloud camera unit that captures images with location information. It will have a small color LCD display that helps initial settings by previewing the camera image and overwriting GPS status and location information. It also includes a PIR motion sensor to trigger image acquisition.

7. Mini market electric solar mutual replenishment module V1.0
The CN3722 constitutes a solar charging unit that supports MPPT maximum power tracking. The charging current is set to 600mA, support battery temperature detection. The TP5100 constitutes a DC charging unit, and the charging current is set to 1000mA, and the battery temperature detection is not supported. The external DC inputs 12V voltages, greater than or equal to 1A, preferably 2A. In the case where the external DC access is charged: The system automatically shuts down solar charging, charging the external DC power supply and prohibits battery power, and automatically outputs the external DC power supply to external systems. The external DC is not input. The system is charged with the battery through the solar panel and supplies the external power. When the solar panel voltage is lower than 6.2V, the charging is automatically turned off.

10, ESP8266 - Humidity sensor with solar power supply with supercapacitor
About a year ago, I built a humidity sensor for my garden. I connect it to the ESP-12E chip that sends it to me by WiFi to me. Humidity level update. In order to power it, I used three AAA batteries. Since the chip has a deep sleep function (approximately 6 months), it has a good operation and the battery lasts for a long time, I want to make something that can continue to run without interference. The sensor is located in a difficult place because it is located in the waterproof housing, which is a bit inconvenient to replace the battery, so I want to be a sustainable battery - utilizing solar energy.
