Water electrolysis is the cleanest technology to gain energy because its combustion product is only water. However this technology still lack of efficiency due to its residue electric field effect. One way to overcome the problem is by utilizing sunlight. Three sets of experiments were conducted and found that by using collimated sunlight the hydrogen production enhance up to 53% higher in comparison to conventional light (31%) and dark field (16%). The polarizibilty and infinitival of the sunlight result in strengthening the electric field in the water electrolysis thus enrich the water splitting. The surface tension and the electrical conductivity were measured to validate the effect of hydrogen bond breaking. The stretching and stressing of the hydrogen bond in order to align the dipole of water parallel to the external electric field was manifested by the behaviour of surface tension. The large separation charges due to the water splitting were demonstrated via the increment of electrical conductivity.
