Solar Panel Efficiency Calculator

To calculate the solar panel efficiency you need to divide the wattage per unit area pmax total area in sq m of the solar module by the stc irradiance value 1000w sq m.

Solar panel efficiency calculator.

Solar panel output calculator estimate the real energy you can get from your solar panels this solar panel output calculatorhelps you estimate the real daily energy a k a. In the spring summer and autumn the efficiency is lower 74 75 in spring autumn and 68 74 in summer because in these seasons the sun travels a larger area of the sky and a fixed panel can t. The efficiency of a panel refers to the ability of the panel to convert sunlight into usable energy. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

The higher the efficiency of a solar panel the more solar power it will produce per square metre. The average cell efficiency of a solar panel is between 11 22. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity. Our solar savings calculator provides more accurate cost and savings estimates by analyzing your current electricity bills rooftop and solar pricing in your area.

In a panel with 20 percent efficiency for instance 20 percent of all the light that hits it will be translated into electricity. This is the simplest way to get any solar pv module s efficiency. In winter a panel fixed at the winter angle will be relatively efficient capturing 81 to 88 percent of the energy compared to optimum tracking. It varies between manufacturers.

Solar panel efficiency is another factor that affects how much energy a particular panel will produce. Nrel s pvwatts calculator estimates the energy production and cost of energy of grid connected photovoltaic pv energy systems throughout the world. This estimator is used to calculate the electric energy efficiency voltage current power area and width when panel units are connected in series or parallel. It allows homeowners small building owners installers and manufacturers to easily develop estimates of the performance of potential pv installations.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
