Specification

Special feature of Liujia Solar Pumpe

Most solar equipment uses the same conventional electronic technology, which means that a stable power supply needs to be guaranteed for smooth operation. Thus these pumps can only be used in areas with consistent clear and sunny weather. In order to compensate this hindrance, multiple solar modules are used together in order to deliver more power than the pumps need, so that the additional power can be used for compensating hazy weather. Another method to overcome this problem is to store solar power in batteries until the pumps need it.

All these ways increase costs and complexity considerably; therefore solar energy has always had difficulties in competing with conventional power supply.

The LIUJIA Solar pump however, is constructed especially to match dynamic solar power. It starts with a small solar current. The more intense the sunlight is, the stronger the pump works. Since the solar pump works with a lossless storage circuit, water will be pumped even when the sunrays are diffused.
