This Counter is a calculator to estimate how much solar power you need to generate and how much battery you need to store the solar power generated by your solar system. Please choose from the available devices, load, and usage time estimation. For device that is not listed in the calculator, please reffer to "ITEMS WATTHOURS - MINUTES/HOURLY".

PLTS - System Sizing Estimator

Lighting / Lampu penerangan

Calculate the wattage of the lamp times the number of lamp to be used in the solar system, Example: 5 pcs of 10 watts light equals to 50 watts. Use LED-based lamp with good efficiency & quality.
Hours per day used

LCD/LED Television

Choose screen size, estimation based on consumption on renowned brands of LCD/LED TV. We do not reccommend CRT Television.
Hours per day used

Computers

As with Monitors, LCD/LED based monitor is reccommended rather than CRT. Printer and Active speaker also adds wattage consumption
Hours per day used

Refrigerators / Kulkas

Count in cubic feet, if there's an icemaker function, choose the next larger size
How many people access the fridge? for 2 persons, average run time is 35%
