We can see that a 300W solar panel in Texas will produce a little more than 1 kWh every day (1.11 kWh/day, to be exact). We can calculate the daily kW solar panel generation for any panel at any location using this formula. Probably, the most difficult thing is to figure out how much sun you get at your location (in terms of peak sun hours).
A 100-watt solar panel installed in a sunny location (5.79 peak sun hours per day) will produce 0.43 kWh per day. That’s not all that much, right? However, if you have a 5kW solar system (comprised of 50 100-watt solar panels), the whole system will produce 21.71 kWh/day at this location.
Consider a solar panel with a power output of 300 watts and six hours of direct sunlight per day. The formula is as follows: 300W ×— 6 = 1800 watt-hours or 1.8 kWh. Using this solar power calculator kWh formula, you can determine energy production on a weekly, monthly, or yearly basis by multiplying the daily watt-hours by the respective periods.
A 1 kilowatt (1 kW) solar panel system may produce roughly 850 kWh of electricity per year. However, the actual amount of electricity produced is determined by a variety of factors such as roof size and condition, peak solar exposure hours, and the number of panels.
In states with sunnier climates like California, Arizona, and Florida, where the average daily peak sun hours are 5.25 or more, a 400W solar panel can generate 63 kWh or more of electricity per month.

A 6.7 kW solar system produces 30.15 kWh of electricity per day. And to build a 6.7 kW solar system, you need 14 500-watt solar panels. If you have a smaller household, you could cover your energy use with a less expensive 4 kW solar system that produces 18 kWh of electrical energy per day, and you can build it with just 8 500W solar panels.
