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.
If you are using only 400-watt solar panels, you will need 13 400-watt solar panels for a 5kW solar system (13 × 400 watts is actually 5200 watts, so this is a 5.2kW system). Quite simple, right? You can also mix solar panels with different wattages.
Take, for example, a 5kW solar system. The summary of all the solar panel wattages in a 5kW system should be 5000 watts (since 5kW = 5000W). Usually, we use the most common 100W, 200W, 300W, and 400W PV panels for this kind of system.
However, there’s a general rule of thumb: A 5-kW solar system can produce 20–25 kWh per day on average. It could reach 30 kWh/day in sunny regions, while output may drop in cloudy or shaded areas. Monthly & Annual Output: This output is sufficient to meet the needs of an average 2–4 person household. Solar panel efficiency is heavily influenced by:
