WorldWater Corp. Introduces Hybrid Solar Pump System – Works With Existing Electrical Grid or Diesel Generators

05.02.2002

Breakthrough 'AquaMax(TM)' Hybrid Can Operate Pumps up to 600 HP,Operating Alone or in Combination With Other Generators

PENNINGTON, N.J., Feb. 5 /PRNewswire-FirstCall/ -- WorldWater Corp.

(OTC Bulletin Board: WWAT.OB) today announced it will introduce its newly

developed hybrid solar irrigation pumping system at California's "World Ag

Expo" Feb. 12-14.

"This new hybrid, AquaMax(TM), is a true breakthrough in terms of both

power and flexibility," said Quentin T. Kelly, Chairman and CEO of WorldWater,

the international solar engineering and water management company based in New

Jersey. "It will work alone or interchangeably with existing grid electricity

or diesel generators and operate pumps up to 600 HP, contributing

significantly to a farmer's bottom line by cutting electrical or fuel costs

whenever the sun is shining, which also happens to be the peak cost period for

grid users," he said.

"The 'Max will be extremely useful for farmers and ranchers anywhere, of

course, but we're introducing it in California because of the high energy

costs there and the resultant efforts by the State to encourage renewable

power usage by rebates and tax incentives, hoping to reduce demand on the

grid," Mr. Kelly added.

The system's newly patented AquaDrive(TM) controller makes it possible for

the first time for solar technology to run powerful off-the-shelf AC pumps,

capable of driving large irrigation pivots or drip irrigation systems,

according to the Company's Executive Vice President, Dr. Anand Rangarajan.

"Other solar pumps are generally limited to 5 HP, so this is a major

technological advance," he declared.

"The hybrid system also ensures that the daily water requirement for

irrigation, or municipal water supply, for that matter, is supplied

irrespective of the weather conditions, even when there is a low level of

sunshine during winter or rainy seasons," Dr. Rangarajan stated.

The AquaDrive(TM) controller converts solar DC current to AC, then

supplies the AC power to the pump from either the solar array or the grid or

diesel generator or simultaneously from both sources, he said. Because of its

power, the AquaMax(TM) system could supply over 50% of many farmers or

ranchers' annual needs by solar alone. The hybrid operation is programmed and

completely automatic, he said, and thus manual intervention is not required to

switch from one power source to the other.
