The average solar panel has an input rate of roughly 1000 Watts per square meter, while the majority of solar panels on the market have an input rate of around 15-20 percent. As a result, if your solar panel is 1 square meter in size, it will likely only produce 150-200W in bright sunlight. [pdf]
[FAQS about How many watts are there in 1 square meter of solar photovoltaic panels]
Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array. [pdf]
A general rule of thumb is that you’ll need one watt of solar power for every hour that you want to run your lights. So, if you want to run your lights for 8 hours per day, you’ll need an 8-watt solar panel. [pdf]
