Inverters typically run about 95 percent efficiency, charge controllers at 98 percent and batteries at 80 percent. The system efficiency is a product of the efficiency ratings of the current handling hardware: inverter (to convert 12 volts DC to 120 volts AC and smooth it into a nice, clean 60-hertz cycle), a battery charge controller, and the deep cycle batteries. Now we can find how many panels you may need by calculating the system efficiency. The further north or south from the equator you go, the fewer hours of insolation. The next step to look up is the amount of direct sunshine your location receives, otherwise known as " insolation." Insolation is controlled by the angle of the sun, the weather, atmosphere, elevation and location on the globe. A 500-watt chest freezer running for ten hours will use five kWh of energy. To compute kWh of a device or appliance, multiply the watts times the hours it runs during the day. The next step is to find out what electrical appliances and devices you are using, how many watts they consume and how long you use them. For example, let's say you use an average of 1000 kWh per month. That being said, the way to determine your usage is to review your utility bills. The important thing to remember is that watts and watt-hours are NOT interchangeable in making your calculations. So, in one hour the 50-watt light bulb will consume 50-watt hours, or. Watt-hours, meanwhile, are the units of measurement of energy used over time. If you have a 30-watt battery, the 50-watt bulb won't light all the way and will quickly run down the battery. ![]() A 50-watt light bulb burns 50 watts of power each time it's turned on. The power (watts) required to run things in your house is not measured the same way as your utility bills show (watt-hours). First, you need to understand the difference between watts and watt-hours.
