context: so If I google how efficient are solar panels and it says the average is roughly 15 to 20% with the max is can get up to is 45%. my question is how is what does that mean?
In: Technology
Solar panels create quite a bit of energy, the storage and usage aspect determines their efficiency. If a solar panel is 50% efficienct that means 1 watt of energy is being used or stored for every 2 watts it’s creating. Say if you work a job during the day, when the sun is the brightest, your solar panels will be creating quite a bit of energy while you’re not at home, you may max out your storage in the first three hours so your solar panels just continue creating energy regardless of your usage, but it all effectively goes no where reducing your total efficiency.
