"Wp" means Watts peak. It is the maximum amount of power a solar panel could produce in perfect conditions. It is not an attainable value.
The way they determine this amount is to take short circuit current and multiply it by open circuit voltage.
Actual max power is closer to 56% of the WP rating.
SOLAR PANEL Of COURSE!(not to be mean)
20Wp stands for 20 Watts peak. It indicates the peak power output of a solar panel or solar energy system under standard test conditions. This measurement helps to understand the capacity and efficiency of the solar panel in generating electricity.
A 250 watt solar panel means that it has the capacity to produce up to 250 watts of power under ideal conditions, such as direct sunlight. This measurement indicates the panel's maximum power output, which can vary depending on factors like weather and shading.
It is never good to answer a question with a question, but I have two questions: 1. does the person asking the question have spell check? 2. does he or she mean "panel?"
Though a non-polluting renewable source of energy, it is not widely accepted today. here's why: When it is hot and the sun is hot, it falls on the solar ray. The heat gets converted into energy through a transformer, and gets stored in a bunch of batteries. When it is night, there is no heeat to get converted to energy, so we have to depend on the stored energy in the batteries. If the energy in the batteries run out, we won't have electricity till the sun comes out again. This goes for cars, and homes.
Solar road technology utilizes solar panels made of photovoltaic cells to convert sunlight into electricity. The photovoltaic cells within the solar panels capture the sunlight and convert it into direct current (DC) electricity. This electricity can then be used to power street lights or other infrastructure along the road.
The output from the average solar panel will never match, much less exceed, the power needed to create one. The hope is that someday they may. In the mean time, people can feel they are doing good for the environment while really hurting it with solar energy.
An efficiency of 14.3 percent means that the solar panel converts 14.3 percent of the sunlight it receives into electricity. While it may seem low compared to some newer panels that reach over 20 percent efficiency, 14.3 percent is still considered reasonable and can be cost-effective depending on the specific application and cost of the panels.
When used in the context of solar power, "Wp" means watt-peak. This refers to the nominal power of a solar cell or a solar panel. Watt-peak, kilowatt-peak, and megawatt-peak are often used interchangeably. Price per Wp refers to the amount of power that a solar cell or panel generates under real-life conditions in relation to its cost
Solar panels is not exactly water proof. Depends what you mean by "Solar Panel" If it is the round or square discs that produces the energy, then they are not at all waterproof and easily get destroyed by it. Solar Panels are normally sold encased in glass with an aluminumframe. Most of these are sold as waterproof and have an estimated lifetime of 10-20 years depending on brand and make.

WHAT DO YOU MEAN BY "Technology or Perish"
