The higher the solar panel wattage, the more solar cells are needed, and the bigger the panel will be. Solar panels that are used on homes are typically in the 300-400 Watt range. Panels of this size are great for home installations due to their size, weight and cost.
However, the more efficient your solar panels are, the more wattage they can produce. With efficient panels, you’ll be able to install fewer panels on your roof to get the same output. Though there are variations in efficiency, standard-size solar panels typically produce around 250 watts.
Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel’s wattage rating tells you its maximum power output under ideal conditions.
Required solar panel output = 30 kWh / 5 hours = 6 kW. Step- 4 Consider Climate Changes: To account for efficiency losses and weather conditions, add a buffer to your solar panel output requirements. Usually, it is 1.2 to 1.5 which is multiplied by the desired output.
