What is the solar panel output?
All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel output is expressed in units of watts (W) and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally costing more and bigger in size, so sometimes are not as cost effective.
The higher the wattage of a solar panel, the more electricity it can produce under the same conditions. Pricing in solar is typically measured in cost per watt (£/W), and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
