Running A 1200 Watt Power Supply Off Of Solar Panels

For this system you would need seven 75 watt solar panels and four 300 amp hour batteries.

Running a 1200 watt power supply off of solar panels.

Determine which appliances you ll be running at the same time. 300 times 4 is 1200 watts. Figure out the duty cycle. For example a weekend cabin used for two days has a duty.

Without them nothing can ever be charged or used. The top panel in the e series comes out at a whopping 435 watts. Now divide the daily watt hours by the wattage produced by one solar panel. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark.

Define your peak instantaneous power output measured in watts. We chose to use 2 150 watt solar panels to power our system. Add their power draws in watts. Compile a list of all your appliances and devices and how many hours per day each will be run.

The solar panel with the highest watt is the sunpower e series a commercial solar panel line. With 60 watts available it would be possible to run six of these bulbs for 24 hours per day on a 100w panel 12 on a 200w panel and 18 on a 300w panel. Installing the solar panels to the roof without spending a fortune. Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels.

The total watt hours per day of energy you ll need. The two panels are enough to charge our battery generator system completely in about 8 hours of. Now if you are going to set up your solar system yourself you will also need a charge controller running from the solar panels to the battery so that the battery doesn t get overloaded. Cfl light bulb a cfl light bulb or a compact fluorescent light was made to replace incandescent light bulbs.

A good rule of thumb is 4 hours.
