Step 1 – Calculate your RV electrical power requirements
12 Volt Appliances
| 12 Volt Appliances | Amps | Quantity | Hours Run Per Day | Total Amps Per Day |
|---|---|---|---|---|
| 10 watt | .8 | 2 | 6 | 9.6 |
| 15 Watt Lights | 1 | 2 | 6 | 12 |
| 12 volt tv | 3 | 1 | 3 | 9 |
| Fan | 2 | 2 | 6 | 24 |
| Furnace | 8 | 1 | 2 | 16 |
| 12 Volt Stereo | .8 | 1 | 3 | 2.4 |
| Propane Alarm (usually 24 Hrs per day) | .21 | 1 | 24 | 5 |
| 78 |
120 Volt Appliances - Using DC to AC Inverters
| 120 Volt Appliance | Amps | X Quantity | X Hours Run Per Day | !ERROR! undefined variable 'totalampsperday' |
|---|---|---|---|---|
| DVD Player | 3 | 1 | 3 | 3 |
| Satellite | 4 | 1 | 2 | 8 |
| Microwave (average .15 hours a day) | 100 | 1 | .15 | 15 |
| Toaster | 65 | 1 | .033 | 2.17 |
| Coffee Maker (Average 0.15 Hours a Day) | 60 | 1 | .15 | 9 |
| Blender | 12 | 1 | .033 | .396 |
| Laptop | 5 | 1 | 4 | 20 |
| Vacuum (Average 0.15 Hours a Day) | 35 | 1 | .15 | 5.25 |
| Curling Iron (Average 0.15 Hours a Day) | 3 | 1 | .15 | .45 |
| Blow Dryer (Average 0.15 Hours a Day) | 125 | 1 | .15 | 18.75 |
| TV | 4 | 1 | 4 | 4 |
| Total amp hours per day | 86 Total Amps |
Step 2 – Calculate your total weekly amps needed
Multiply total amps hours per day by the number of days per week (i.e. weekend camping: multiply total amp hours x 2 days, full-time camping: multiply total amps per day x 7 days).
_____________ amps per x ______________# of days of use per week = ________________ total amps
Step 3 – Find the perfect solar panels for your RV
Match your estimated weekly amp usage with the right RV Solar Panel Kit
1-98 Amps
100 Watt RV Solar Kits
98-140 Amps
200 Watt RV Solar Panel Kits
141- 233 Amps 2
200 Watt RV Solar Panel Kits
231-466 Amps
>200 Watt RV Solar Panel Kits
466 Amps
Rates are based on a 12V system with 5 hour charging times. Actual charging times will vary depending
on geographic location, time of year, angle of the sun relative to the RV solar panel and, weather conditions.
