Solar Costs & Return On Investment
Don't know how many solar panels you need?
Calculate your Solar System for you hereSelect a country first.
For the excess energy you generate, you will sell it to your electricity provider but for a much lower cost, so the better option is to include a battery here.
This is a contract option provided by your electricity provider stating that for excess energy you generate, you will get it back at night, like using the grid as a battery. This is the best option if available because you don't need to buy a battery.
This percentage is crucial for the 'Net Billing' simulation. It helps determine how much of your own solar power you use directly during the day versus how much expensive electricity you must buy from the grid after sunset. This directly impacts your savings and the recommended battery size needed to cover your nightly consumption.
