Solar Home Lighting System
Q: Where can we use Solar lighting system?
Solar lighting system can be used anywhere where we need lighting. It is a source of clean energy and can be used at home, offices, hotels, hospitals, rural areas, remote villages etc.
Q: How much light does a solar lamp provide?
A: In solar lighting system lamps used are CFL ( Compact Fluorescent Lamp ). It consumes 70 - 80 % less energy than ordinary incandescent bulbs. The light output of 5, 7, 9, & 11 watts CFL's can be compared to 25, 40, 60 & 75 watts ordinary bulb respectively
Q: What is the lighting life of a solar lamp/CFL during each day?
A: 3-4 hours a day
Q: What happens to the productivity of the system during rainy season?
A:Solar lighting system generate electricity in cloudy weather although their output is reduced. Solar PV needs only sunlight not the heat of the sun, therefore the system even can work in rainy season i.e. in diffused light conditions. Hence, in our area, solar lighting system works almost throughout the year.
Q: How the solar lighting system work?
A:When sunrays falls on solar cell inside the solar module electricity is generated. This electricity is stored in the battery. This battery delivers electricity to the lamps (CFL) whenever required. The charge controller regulates total operation of the system.
Q: What is the expected life of using components in solar lighting system?
Yes, But these appliances consume more power due to their high wattage. So the solar modules, batteries etc. required will be of much higher rating.
Q: Can we operate television, refrigerator, fan etc. on solar lighting system?
A: Yes, But these appliances consume more power due to their high wattage. So the solar modules, batteries etc. required will be of much higher rating.
Q: What is the maintenance required for solar lighting system?
A: Though we supply maintenance free battery, regular cleaning/ dusting of the module is a must as per the instructions given by the installer at the time of installation.
Q: What are the advantages of solar lighting system?
A: There are various advantages of solar photovoltaic technology;
»There is no need to depend on conventional electric supply or other fuel like Kerosene, Gas etc. So you can fully rely on solar lighting system to deliver light for specified hours throughout the year.
»As the electricity is generated by using sunlight, which is freely available anywhere. So the electricity can be generated at any remote place, where regular electricity cannot reach.
»Solar lighting system works on low voltage 12 VDC, so it is much safer compare to 230V Ac supply voltage.
»Solar electricity saves the conventional fuels & reduces the environmental pollution.
»Very easy to install & operate.
Q: Why solar lighting system are expensive?
A: The main costly component in solar lighting system is solar module. The manufacturing process of silicon cell used, in solar module is very complicated & costly. Hence, the overall cost of solar lighting system is on higher side.
Q: Is it inverter/ UPS system?
A: No, solar lighting systems are not inverter/ UPS systems because of two reasons Firstly we generate our own electricity & use this energy daily, & not only during power emergency. Secondly the electricity generated is free of cost, while running of inverter or UPS comes at a cost, since they need to be charged with electric power to function optimally during emergency
