solar panel installation

1. Abeynayake A.A.D.I- 180002H Residential solar energy system 1 ENERGY TECHNOLOGY AND ENVIRONMENT ME 4242

2. Solar technology is used to catch Solar radiation and transform it into usable energy. Photovoltaic panels(PV) Main components of the System PV solar panel system Inverter Monitoring panel Cables Battery Introduction 2 PV module Efficiency (%) Mono - Si 15 Poly-Si 11 a-Si 8

3. Selected best field 3 Length = 370 inches Width = 180 inches   Roof (inches) Panel (inches) Number of panels Length 370 39 9 Width 180 65 2 Required number of panels 18 Required number of solar panels = 18 Estimation of the Required number of solar panels

4. Maximum possible daily electricity generation According to the topological map “Udugalmote” area is in the shaded region labelled “1534kWh”. Maximum possible daily electricity generation = 17.70 kWh/Day E lectricity potential topo map in Sri Lanka 4

5. Requirements for the calculation of the installing solar panel system 5 Yearly average daily horizontal irradiation = 5.38 kWh/ /day Longitude and Latitude - Latitude = - Longitude = Plate inclination angle = Monthly averaged panel temperature = By using above data, Maximum possible electricity output for 18 panel can be taken as 20.7  

6. 6 Annual saving by installing panel system Month Number of units August 97 May 153 September 131 July 157 Average number of units 134.5 Monthly electricity bill = Rs. 4,752.00 Annual electricity bill = Rs. 57,024.00

7. 7 Simple payback period of cost for installing solar panel system Initial cost 1 Cost for panels 2 Inverter 3 Solar net meter and other components 4 Transportation and labor cost Rs 1,219,600.00 Energy generated by panels per month = 20.7 *30 = 621 kWh   Annual energy generated and exported to the grid = (621 – 135) *12 = 5,832 kWh Annual income from the energy exported to the grid in first 7 years = Rs. 898,128.00

8. 8 Simple payback period of cost for installing solar panel system ctd… Initial cost Annual income from the energy exported to the grid in the first 7 years Annual income from the energy exported to the grid after 7 years Annual savings from your project during the first YY year by installing solar panels Payback Period = 6 years 6 months . 898,128.00 + 5,832 * 15 * (YY-7) + 57,024.00 * YY = 1,219,600.00

9. 9 Used Inverter to the system Used to DC AC Types of inverters - String inverters - Grid tie inverter - Micro inverters - Power optimizers - Hybrid inverters Grid tie inverter is used because, It is shut off immediately in the event of a power outage It has built-in monitor
