The LED bulb is like a car crawling through a parking lot while an air conditioner is driving at highway speeds. For solar panels, a small amount of wattage is ~500W or less, while a large home solar panel array can have 2,000W or more worth of panels. Watt-hours (Wh) measure the total energy used (or generated) over a time period.
You can calculate how many solar panels you need by dividing your yearly electricity usage by your area''s production ratio and then dividing that number by the power output of your solar panels. To put it simply: Number of panels = annual electricity usage / production ratio / panel wattage
On average, 15-20 solar panels of 400 W are needed to power a house. This can vary depending on your solar panels'' wattage rating, solar panels'' efficiency, climate in your area, your total household electricity consumption, and how much of that you want to offset to your solar panels.
As we calculated earlier, the California household needs a 7.2 kW system to cover its electricity needs. A comparable household in Massachusetts needs a 9.9 kW system. So, in less sunny areas like Massachusetts, you might consider choosing highly efficient solar panels to maximize your energy output per square foot.
