12v18 watt solar power generation

Both 12V and 18V panels are listed for sale on Amazon and inspection of the electrical specs shows that they are essentially identical. How the Ukraine Crisis impact the energy industry?

"12V panel" means 18 volts. If it is designed to work with 12V panels it will work with your panel. Note that this inverter requires a battery. That inverter needs batteries, a charge controller in addition to the solar panels.

And since the battery was 12V it was easy to think of the panel as also being 12V. The true maximum power point of these panels (and most modern 12V panels) is close to 18V and thus should be considered 18V panels not 12V. Also, most panels advertised as 24V are really 36V or two 18V panels in series with an open-circuit voltage well above 40V.

Solar panel output, fundamentally, represents the quantity of electrical energy that solar panels can produce over a given period. This output is a critical measure of a solar panel system's efficiency and its capacity to convert sunlight into usable electricity.

A friend of mine gave me four 18v solar panels (atached image) that i wanted to use on the inverter. When sitting in bright sun, i measured around 21-22v, and in shaded areas, i measured around 15-16v per panel.
