Advantages of Solar Water Heating System: Sunrays remain perpendicular to cylindrical absorber surface of vacuum tubes. It can absorb more energy resulting in more efficiency of the tubes. Reduction in peak load. Reduction in rate of global warming. Negligible scaling of tubes. Higher efficiency on high temperature. Less space & more economical. Long life more than 15 years. Maintenance Free. Suitable for air conditioning.

Advantages Energy Efficient. Environmentally benign as it improves the ambient air quality with least power consumption. Creates positive pressure in the space conditioned. Provides clean, filtered and dust free air. Minimal space requirement as compared to air washers. Reduces inlet air temperature by upto 12°C. Easy & inexpensive to maintain as compared to air-washer. Has high air pressure, can cover a longer distance.

Solar photovoltaic system works on the principle of converting sunlight energy into electric energy. This is done by using photovoltaic silicon solar cells. When light energy strikes on solar cells, energy is transmitted by the movement of electrons. The flow of electrons results in a potential difference. This potential difference is stored in rechargeable batteries and can be used whenever needed.
