- 2. What • A solarwater pump system is essentially an electrical pump system in which the electricity is provided by one or several Photo Voltaic (PV) panels Where • Solar water pumps can supply water to locations which are beyond the reach of power lines/ frequent power cuts/Power is not enough Why • Large reduction in carbon emission • Early pay back period • Long Life (Around 25 Years) • Reliable source of power supply • More saving due to low maintenance • low yielding borehole has time to refill Solar Irrigation

- 4. ADVANTAGES • It helpsin saving energy. • There is no fuel cost - as it uses available free sun light. • No electricity required. • Can be operated lifelong. • It works everywhere. • It is also useful for clean, drinking water sanitation and also irrigation. • The dependence on rain is reduced • It creates wealth for farmers by increasing no. Of crops.
- 5. DIS-ADVANTAGES • High initialcost • Non-working at night • Solar panel inefficiency. (A solar panel Can convert < 22% of the energy it gets from the sun into electrical energy) • Bulky solar panels are required for the • Large power production
- 6. WHAT ARE SOLARPOWER PANELS? • A solar power panel is made of photovoltaic cells arranged in a configuration that can contain 32, 36, 48, 60, 72 and 96 cells. • A solar panel comprising 32 cells typically can produce 14.72 volts output (each cell producing about 0.46 volt of electricity). • These cells are arranged in a frame that is either rectangular or square. • The size and weight of solar power panels increase as the number of cells increase. • Solar power panels with higher cell configuration are used in commercial applications to generate electric power.
- 7. HOW DO SOLARPOWER PANELS WORK? • The cells in a solar power panel are photovoltaic, they absorb energy from the sun’s rays when exposed to the sun. • This energy is transferred to the semiconductor creating an electric field delivering voltage and current. • Power is derived from the equation P (power) = V (voltage) x i (current). for instance, a solar power panel comprising 72 cells generates 33.12 v.

- 8. FEATURES OF SOLARPOWER PANELS • Solar power panels can come in varying sizes but the common size for commercial applications is 77 x 39 inches and for residential applications, the common size is 65 x 39 inches. • The size of an average solar panel is dependent on the number of cells (1 cell = 15.6 x 15.6 cm) encapsulated in it and the panels' application. • The cells produce relatively constant voltage but current can vary with the intensity of light falling on the solar power panel. • Photovoltaic solar panels can come in three types – monocrystalline silicon PV panels, polycrystalline silicon PV panels and amorphous or thin film solar PV panels. • A typical solar power panel can generate 230 to 325 watts of power. • Any power generated can be used directly to charge a device that runs on DC current. • By using an inverter, DC power can be converted to AC to run devices that use AC current

- 14. Difference between Mono-crystalline andPoly-crystalline solar cells • Price - monocrystalline solar panel price is more than that of polycrystalline solar panel price • Efficiency falls in the 15-20% range while that of polycrystalline panels falls in the 13-16%. • Mono-crystalline panels are blackish while polycrystalline panels are blue in color • Monocrystalline panels enjoy a little longer lifespan than polycrystalline solar panels.
