Solar energy: Portable Solar Power Charge and Storage System

Solar energy: Portable Solar Power Charge and Storage System

Nabell Corporation

Pushing the Limits of Solar:    
Portable Solar Power Charge
and Storage System

Nabell Corporation has recently developed the nanoGrid, a portable solar power system that can generate and store electric power from sunlight and AC power supply. It features superior weather resistance and can charge electric devices anywhere, at any time.

The nanoGrid is comprised of foldable solar panels that can neatly and easily be stored for later use. It even has straps to wear it as a backpack. The storage system weighs 6kg, with a folded size of 50cm×42cm. The nanoGrid is ideal for supplying electric power to devices ranging from PCs to LED lights to mobile phones.

The best part about the technology is that it works in non-electric power source areas and even when presented with disaster conditions. In terms of outdoor leisure activities, it is designed for both convenience and practicality for activities such as camping.

Major Features and Advantages

bella_solar_title-512x671There are certainly other solar power systems out there, but they are large and cumbersome. The benefit of the nanoGrid is its portability and relatively small size. Advantages over other systems include the following.

I. Portability
Because it can be folded and packed up tight, it is very compact and portable. It can easily be taken anywhere.

II. Generating Electricity
This product does not require any other facilities, fuel or transmission lines; just sunlight. In fact, it has been proven to generate power even in shade. The nanoGrid can be a solution in rural non-electric power source areas.

III. Durability and Reliability
After extensive testing through bends and drops, the nanoGrid proved to be extremely durable against impact, heat and cold. It is also weather resistant, so rain will not affect its efficacy.

nanoGrid is thought to be the most reliable resource of electric power when it comes to the challenges of natural disasters.

Conceivable applications

The nanoGrid is a portable solar power system that can generate and store electric power from sunlight and/or AC power supply and charge electric devices anywhere anytime. The nanoGrid which consists of foldable solar panels and a storage system weighs 6kg in total, and the size is 50cm×42cm (folded). The nanoGrid can supply electric power to electric devices such as PCs, LED lights, and mobile phones not only in a non-electric power source area and under disaster conditions but also for outdoor leisure activities, as it is optimally designed for both convenience and practicality.

Competitive advantage

2Compared with other large solar power systems, our proposed small-scale system has the following advantages.

1) Portability
The nanoGrid is a compact portable system with foldable solar panels(the size is 50cm×42cm folded) with a total weight of 3kg

2) Electricity Generation
The nanoGrid does not need any other facilities, fuel or transmission lines; it only requires sunlight* in order to generate electricity.
* Verified that it can stably produce electricity even in the shade.

3) Durability & Reliability
Bend and drop tests were conducted under natural disaster conditions, and some tests are still ongoing.

4) Waterproof
The nanoGrid is waterproof.

Due to these advantages above, the nanoGrid can be a reliable resource of electric power in the event of natural disasters.
