Question:

Whats the annual energy output of the average solar panel.?

What is the average annual energy output of solar panels that can be installed on the home?

Answer:

Average Solar Panel Output
The energy output is highly dependent on the location. For a specific area, you can look up the equivalent peak sun hours per day here: rredc.nrel /solar/old_data/nsr... Let's say that it says the peak sun is 5 hours / day in your location. Then a typical 200-watt panel would have 5 x 200 = 000 wH = .0 kWh per day, or 365 kWh annually. The tables above already take into account average cloudy days, and seasons. A typical size installation would have perhaps 6 of these panels, but it could be less, or much more.
The output of a solar panel would depend on your location and panel size. Most solar panels are rated using 000 Watts per square metre from the sun. This is only possible at the equator. Some supplier have online estimators for output depending on your location. Solar panels rate up to about 250 Watts per panel. I have an online calculator to work out the costs and benefits of solar. You can compare the costs of solar setup and 25 years of electricity versus buying from the grid.
The Sun provides about 360 W per square meter above the atmosphere (Solar Constant). Approximately 2/3 of the energy is lost in passing through the atmosphere, which means you should anticipate at best about 450 W per square meter arriving at a solar panel directly facing the Sun on a clear day. You can anticipate an efficiency of approximately 30% for a typical solar collector, or about 00 W to 40 W per square meter of solar collector being delivered as electricity under the best of conditions. These are estimates, but we need better information on the actual power delivered per square meter of a particular solar collector under the best of conditions before we can begin to estimate the amount of energy per meter squared collected over a typical year for a given location.
