Buy solar panels. Don't just look at "watts."

Most people who buy solar panels usually ask one question: "How many watts is this panel?" Which is not wrong, because it is a total power indicator. But if you want the system at home or at the park to work well, stable and not easily broken, we have to look deeper.

To visualize it simply, imagine that electricity is like water in a pipe:

Watt (W) - is the "total amount of water" you'll get in an hour.

Pressure (V) - is "water pressure" (how strong the water is).

Current (I) - is the "size of the water pipe" (how much water flows out)

Why do we essentially have to look at V and I?

Voltage (V) is the "pusher":

If you're going to pump high water (like the groundwater pump in my garden) or have a long wiring, if the pressure (V) is not enough, the water will not reach the end, even if the panel is not up to the start-up stage, the system is just a glass plate in the sun.

Current (I) is "heat":

If you choose a panel that gives you a very high current (I), but with a small wire, the next thing is "heat." It's like we're trying to compress a huge amount of water through a small pipe until the pipe explodes. In the light system, the wires melt or fire.

A simple way to observe before buying:

Look at the V (Voltage): Fits our appliances or Inverter? (Like choosing a pump to suit the height)

See I (Amps): Can the wires we walk for? (Like choosing a pipe to suit the amount of water)

A brief summary, typical of the electrician:

"Watt" says how much we have, but "voltage and current" says whether we can use it...It's like buying a car. Don't just look at the horsepower. See what fuel you can fill and how many tons you can carry!
