1. Collect some data viz. Latitude of the location, and solar irradiance (one for every month) ___________________________________________________________ 2. Calculation of total solar energy. ___________________________________________________________ 3. Estimate the required electrical energy on a monthly/weekly basis (in kwh) Required Energy Equipment Wattage X Usage Time. __________________________________________________________ 4. Calculate the system size using the data from 'worst month' which can be as follows: ____________________________________________________________ a) The current requirement will decide the number of panels required. ____________________________________________________________ b) The days of autonomy decides the storage capacity of the system i.e. the number of Batteries Requried. __________________________________________________________ c)Suggest Power Saving Products
