How effective are solar photovoltaic panels
Modern panels reach 18–23% efficiency. That means they convert about one-fifth of sunlight into usable power. But efficiency is only part of the story. Real-world performance changes with temperature, shading, tilt angle, and even the quality of the inverter or battery. [PDF Version]
How many solar panels are needed to generate 1GW
To put this into perspective, to generate a gigawatt of energy, 3. 125 million solar panels would be required. Solar panel efficiency is also important, as this determines how much energy the panel can convert from sunlight into electricity.

How many volts of solar panels are needed for a 12v small water pump
For light-duty use, such as charging phones, LED lights, or a small fan, a 100W to 150W solar panel is often enough for a 12V 50Ah or 100Ah battery. [PDF Version]
