Solar Power FAQ's (Frequently Asked Questions)
Solar Power FAQ's (Frequently Asked Questions) 1. Solar panels cost - 650 kwhr / 30 days = 22 units per day. If you want to generate one unit, you need 200 watt solar panel To generate 22 units you need 22 x 200 = 4400 watts panels taking in to inefficiencies of the total system we need 5000 watt of panels Cost of the panel is Rs 60 per watt 5000 x 60 = Rs. 3,00,000. 2. Battery - To store this in to the battery (assuming that all the eneregy generated by the solar panel will be required to store in the batteries for using it in night time) you will need batteries that can store 25 Kwh of electrical energy. Th cost of the Tubular Battery battery will be Rs. 10,000 per kwh Total cost of the lead acid batteries will be - Rs. 10,000 per kwh x 25 kwhr = Rs. 2,50,000. Now it is not possible to charge these batteries within 5 to 6 hrs when sun is shining. You need 4 times the normal capacity. So the total cost of the batteries will be - Rs. 2,50...
