CPM Solar will compute your load requirements, and add up the ratings of all your appliances.This is the amount of power your PV system should be capable of pumping. When making this choice it will be optimal for you to decide on certain behavioral changes, eg: Not running your Dishwasher & Heater simultaneously. This will result in a smaller system and we will explain this to you at our initial consultation.
Once we have decided on the load, we will compute your energy requirements.
Then, we calculate the maximum size of the PV system that can be put on your roof. This is dependent on shadow free regions and size, and the efficiency of the panels we reccomend. We will estimate shadow free areas using various tehniques.
Finally we calculate the maximum amount of energy our system recommendation can generate and its variation within a day as well as variance across months/seasons. We will explain these variations to you during our consultations.
