How many watts does a solar panel produce?
Related: How many solar panels do I need? Typically, a modern solar panel produces between 250 to 270 watts of peak power (e.g. 250Wp DC) in controlled conditions. This is called the ‘nameplate rating’, and solar panel wattage varies based on the size and efficiency of your panel.
How much sunlight does the US get?
The US ranges from about 4 hours – 6 hours of sunlight per day, on average, see the below map. Let’s estimate you get about five hours per day to generate that 30 kWh you use. So the kWh divided by the hours of sun equals the kW needed. Or, 30 kWh / 5 hours of sun = 6 kW of AC output needed to cover 100% of your energy usage.
What is the ratio of AC to DC?
Yep, like the band, AC/DC. Because of physics, there are losses in converting the energy from the sun into DC power, and turning the DC power into AC power. This ratio of AC to DC is called the ‘derate factor’, and is typically about .8. This means you convert about 80% of the DC power into AC power.
