These numbers only take into account the energy needed for air conditioning.
How much watt solar panel required for ac.
A single solar panel is going to charge your batteries much too slowly you ll use up the stored electricity faster than the solar panel can charge them again.
For any given energy production target you need fewer panels if their individual wattage is higher.
During the summer the ac pulls between 450 watts and 700 watts on powerful mode it draws about 1 000 watts.
More is needed with more clouds.
15 minutes of charging would run it for an hour.
This is also assuming of course you have a lot of battery power too.
In seattle you d need a 4 75 kw installation about 18 panels.
Follow along to calculate the amount of solar panels your specific home will need.
The average system size in the u s.
So to power a 13 500 btu air conditioner 1 500 watts of solar panels is the minimum required.
In order to calculate the below data we averaged annual kwh production in the top 12 solar states and assumed standard 250 watt panels in order to calculate how many panels you would need.
Likewise if your solar panels puts out 240 watts that one hour charging time would run a 60 watt appliance for four hours.
This is assuming you are considering using 12 volt rv grade panels.
With 300 watts on our own rig this means at peak i can expect to generate 25 amps of charging if i m lucky.
Here s what s really important about all that.
A typical american home will need 14 36 solar panels to cover their power bill and at least 227 square feet of rooftop space to accommodate the solar panels.
You will need at least 1 800 watts of solar panels to run your rv air conditioner.
But for the sake of argument if we assume the best case that 100 watt solar panel can provide just over 8 amps of energy for charging.
We suggest a battery bank of 800 amp hours.
When roof size is limited efficient panels with a high wattage can make the system more compact.
As a side note for heat it pulls about 700 watts to 1 000 watts 1 100 on powerful.
To provide about 14 5 kwh of electricity each day in arizona you d need a 3kw solar installation or a system with about 12 solar panels.
If you leave it charging a battery for two hours you could run a 60 watt appliance for one hour.
