Solar power can also be used in solar water heating systems. Infra red radiation from the sun is collected to heat water for domestic (baths, washing, etc.) or commercial use, such as swimming pools. This can dramatically reduce electricity or gas bills.
Solar power provides energy without any emissions of greenhouse gases and its operation is silent. Lack of moving parts means they require minimal maintenance.
Solar panels can also look aesthetically pleasing, keeping the environmental impact of this technology low. The price of solar energy is constantly reducing as the technology becomes more advanced and economic to produce.
