It will take a 40 watt solar panel 7 days to charge a 100ah 12V battery. This is assuming the solar panel produces 200 watts a day. If the battery is discharged at 50%, it will take 3 to 4 days to charge. But again this assumes the solar panel produces peak output consistently.
Here are some examples. A 40 watt solar panel can provide 40 watts of electricity per hour. This is the maximum output you can expect, but depending on the weather, it may fall below this value. It will take a 40 watt solar panel 7 days to charge a 100ah 12V battery.
This means the whole solar panel system can generate 7.2 kWh of electricity in a day. This is calculated by multiplying the number of panels by the output per panel: 10 x 0.72 = 7.2kWh. The output per m² of an average 350W solar panel in the UK is about 132.5kWh.
Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.
40W solar panel is enough to recharge your small appliances like cell phones, portable Fans, and LED lights. So in short, you'll only be able to get 200 watts of total power output from your 40W solar panel so is that what you need? then it is enough for you.
