Power Storage |
| |
Power Storage is a very important factor in solar powered illumination products. During the day-time the solar panel transforms the energy of the sun to electrical energy which in turn must be stored up for night-time use, at which point the energy storage device furnishes the energy needed for illumination. The effectiveness of the product depends on the effectiveness and usage life of the power storage device. This is the reason that Maki Solar is so absorbed in power storage research, and how to incorporate the latest research into our products. In addition we seek to promote product quality, to insure that all our products are of the incomparable quality. |

Brief Battery Introduction
|
There are many different types of storage devices or batteries being used in solar products. At the present time the most commonly used types in the industry are the Ni-Cd (Nickel Cadmium), Ni-MH (Nickel Metal Hydride), and lithium batteries. Maki solar has taken great pains to test a variety of different options to really select the most appropriate storage device, in order to ensure that our products have the optimum efficiency and performance. |

Battery Quality Control
|
Maki solar only selects batteries manufactured by ISO9001:2000 certified manufactured producers. Moreover prior to installation, we make sure that each and every battery passes our testing process (see picture below). If there is any problem with the battery of they do not meet the specified standards they are classified as substandard and sent back to the producer. In this way we can guarantee our product’s quality and safety for use. After installation of the batteries the effectiveness of the final product is again tested before it is shipped out. This meticulous monitoring process is what allows us to offer increased product quality and stability, and to build up customer trust in their reliability. |

| Maki Solar Power Storage Technologies |
At present, the technology for lithium, nickel cadmium and nickel metal hydride batteries has already been well-developed, and they are in common use in many products as reliable energy storage devices. Problems connected with their design and net cost have been resolved. However our design engineers have focused on finding solutions to problems encountered in the use of lead batteries. The limitations of traditional batteries are ultimately related to the chemical reaction that occurs therein. Maki solar has made a breakthrough in this area. We have improved the technology to find ways to overcome usage life and temperature limitations as well as large electrical current requirements which also have a direct influence on usage life. Two years ago we started to study ultracapacitor technology and since then have begun to integrate this technology more and more into our products. Up to the present time these ultracapacitor products have already entered the market place in to most countries. Product quality has be stabilized and battery usage problems have successfully been overcome. Our ultracapcitor products have a usage life of 5-7 years, an increase 2-3 times that of the 2-3 year lifetime of traditional batteries. Not only has the battery life increased but this also saves on the manpower and cost needed to change the batteries.

The ultracapacitor advantages:
- Energy efficiency
- Environment-friendly (Low toxicity of materials used.)
- Virtually maintenance-free
- Operates reliably in harsh environments
- Working temperature (-20℃ to 60℃)
- Wider storage temperature (-25℃ to 80℃)
- Little degradation over hundreds of thousands of cycles.
- Long life－10000~1000000 recharging cycles, 7~10 years

| Ultracapacitor |
The Ultracapacitor is a futuristic rechargeable energy storage device.The charge is stored electro statically (i.e., physically) in polarized layers between an ionically conducting electrolyte and a conducting electrode. Moreover, the ultracapacitor ‘s physical properties allow it to store energy much faster, i.e., with more power, than a battery which must rely on time-consuming chemical reactions. Also, these physical properties mean vastly superior tolerance to repeated charging and discharging.
Compared to traditional batteries, the ultracapacitor has one tenth the energy density of the former, but more than a thousand times longer cycle life.
