Harvester™ Performance Calculator: Mobile & Ground
item#: HM007, HM008 and HM010; HG007, HG008 and HG010

This Run Time Calculator will determine how long (run time) The HarvesterTM, The HarvesterTM 2X and the HarvesterTM 3X will run a list of appliance(s) of your choice.

The Calculator will first figure the total average watts for your application, which is based on the appliances selected and what percent of the time you intend to use them.  Then, based on your geographic location, the Calculator will determine the run time of each HarvesterTM product for your application. 

The Calculator will also indicate the time required to recharge The HarvesterTM products using the power of the sun and/or a wall charger.

Step 1: Add

     Appliances have been gathered in lists.
     Select appliances you would like to run.

    Choose one or more appliances from the lists below.
    Click the Add button to add the selected appliance to the list in Step 2.
        (For examples of application packages, use SolarOne Packages.)

                                  

Step 2: Review

Appliances are added up and total equivalent watts are calculated.  You may add additional appliances if desired.     The table will automatically recalculate as items are changed or added.

View list of appliances chosen.
Add your own appliances.
Change appliances from list.
(Percent Run Time is percent of time appliance is used in one hour or in one full day.)
(Wattage ratings are only estimated per appliance, if actual wattage is known change below.)

Step 3: Location

How much solar power you can harvest depends upon your location and the time of year.  This is called the solar index.   

     Determine solar index. 
     Click image for a pop up world map.
     Solar Index at chosen location:
    
     Select time of year for solar index.

    
     Select type of tracking.

    

Solar Index data based upon the average index
from the last 10 years, collected by NASA.

Results Explanation:

  • Run Time (Hours) estimates how long the HarvesterTM will power load with no sun.
  • Run Time with Sun (Hours) estimates how long the HarvesterTM will power load with solar input when appliance is first turned on.
  • Solar Charge Time (Days) estimates how many days of sun needed to charge battery, determined by your solar index.
  • Wall Charge Time (Hours) estimates how long to charge the battery from wall only.
  • Wall + Sun Charge Time (Hours) estimates time needed to charge from wall after charged in one full day of sun, at determined solar index.

Run Times are estimates only, actual times may vary. Calculations are based upon the following:

  • 100% Battery at start.
  • Inverter manufacture rated efficiency.
  • Battery drain to 15%.
  • Charge Times return 100% battery
