Atiar Ali (EEE, UITS) ID-08410079 asuvro@gmail.com (facebook & email) Solar panel (PV) is a device which can convert energy from light energy (proton) to electrical energy. Question. Mail me at : [email protected] http://www.elnova.com , Nice work still few things I would like to explain . sir; I’m unable to understand MS (Excel Spreadsheet // Calculate Size of Solar Panel, Battery Bank and Inverter) please guide me. All credits goes to mr. Jignesh Parmar! This MS Excel spreadsheet calculates the following: This is great work,since it helps on designing an off grid system with a battery bank i thought it should also include the charge controller section.Most PV system builders struggle a lot when it comes to choosing the correct charge controller which works perfect for the system being built. Regards Nick, Really excellent job u r doing for the electrical engineers. Solar Panels power generation is commonly given in Watts e.g. Richard's Microsoft Excel spreadsheet 'Solar Power' can be downloaded here. Required EXIDE SOLAR BATTERIES. No power generation system is 100% efficient, in fact with solar panels the efficiency is quite low only about 22% of all the energy they collect is converted to usable power.
