Here you will learn how to calculate the annual energy output of a photovoltaic solar installation. r is the yield of the solar panel given by the ratio : electrical power (in kWp) of one solar panel divided by the area of one panel. Example : the solar panel yield of a PV module of 250 Wp with an area of 1.6 m2 is 15.6%.
For the exact solar panel computation, take your location, weather conditions, panel size, system efficiency, and derating factor as discussed in the blog into consideration. Divide the total monthly energy needs (1000 kWh) by the number of days in a month and divide by the panel output to get a precise estimate.
The efficiency of a solar panel refers to the amount of sunlight that is converted into usable energy. Panels with higher efficiency are able to generate more power from the same amount of sunlight. Therefore, it’s vital to consider the solar panel efficiency. Below is the formula to calculate it: Efficiency (%) = [ (Pmax ÷ Area) ÷ 1000] × 100%
The first factor in calculating solar panel output is the power rating. There are mainly 3 different classes of solar panels: Small solar panels: 5oW and 100W panels. Standard solar panels: 200W, 250W, 300W, 350W, 500W panels. There are a lot of in-between power ratings like 265W, for example. Big solar panel system: 1kW, 4kW, 5kW, 10kW system.
Divide the actual solar panel capacity by the capacity of a single panel to determine the number of panels needed. For example, if your average daily energy consumption is 30 kWh and the system efficiency is 80%, and you have an average of 5 hours of sunlight per day, you would calculate your daily energy production requirement as follows:
The lifespan of a solar panel can be calculated based on the degradation rate. System loss is the energy loss in the system due to factors like inverter inefficiency, cable losses, dust, and shading. The amount of solar radiation energy received on a given surface area in a given time is called solar insolation.
