Innovative solar technology can even operate with indoor lighting

08-08-2017 | Saelig | Power

Saelig Company has introduced the patented Sol Chip Pak power modules which offer day/night non-stop functionality by combining state-of-the-art solar cells, a rechargeable battery, and advanced power management circuitry. They include all the components that are required to harvest energy from ambient light, charge a built-in rechargeable battery, and deliver a stable voltage to a load. Their patented technology integrates solar energy conversion with VLSI techniques to produce unique ambient light harvesting devices that can even extract energy from office lighting to provide 24/7power. These versatile boards, based on the company’s unique Saturn cells, provide power even in office light conditions.

The output voltage of these ‘everlasting solar batteries’ is regulated to 3.6V, but other voltages are available by request to suit alternate applications. Versions are available with one, two, three, or six Saturn solar cells depending on the power needs. The six-cell version provides an average output current of up to 750uA from the integrated solar cells, with up to 1.5A peak current. The capacity of the 3.6V onboard rechargeable batteries in the series is 190mAh-1100mAh.

The SCP series of boards allow designers to build fit-and-forget light-powered products that can recharge themselves. Existing products can be modified by simply disconnecting a device's traditional batteries and plugging in an SCP to create a self-powered, no maintenance device. All that is needed is a small window to allow light to reach the board - it does not even need to be pointed to the sky. Operable in sunlight and indoor environments, it removes the need for a battery power source in low power applications, removing maintenance headaches and hazardous battery waste issues.

The SCP series is ideal for designing in to remote sensors and monitoring systems that are used in diverse applications such as: agriculture, farming, drip-irrigation systems, weather testing, as well as security, IoT, wireless sensor networks, wearable electronics, etc. Other applications include smart city solutions for everything from parking to security and utility meters, data loggers, GPS emergency locators, animal tracking devices, GPS asset/container tracking, GPS vehicle tracking, environmental measurement and RFID devices and more.
