I have a 2 5kva inverter with two 12v 200ah batteries which solar system will be suitable to charge it.
How many solar panels needed for rv a x.
Will that many panels actually fit on your roof.
Like most things rv solar power has pros and cons and you will want to carefully consider all the factors before you decide to buy some panels for your roof.
By this estimate we ll need about 2 500 watts of solar panels just to break even on the ac unit s consumption.
How many solar panels are needed to charge 8 x 200ah batteries.
But i have seen plenty of 160 watt panels.
Now i ve not seen a 133 watt solar panel for sale.
But if you plan to use typical 12 volt rv solar panels you will likely need more solar.
You might know the square footage of your house but that doesn t tell you the area of roof that s available to fit solar panels.
We ll need about twelve 200 amp hour solar panels and one 100 amp hour panel to run the ac.
For example if the amount of power needed is 5 000 watts and each shingle is rated at 50w you need 100.
Divide both sides by 30 and you need 1 33 100 watt solar panels.
Solar shingles are smaller than panels and their wattage is lower as a result.
40 amp hours per day 30 amp hours per panel per day x panels.
We would recommend 1 800 watts minimum.
100 watt solar panel approximately 6 amps hour in direct summer sun no clouds here s an example of our calculation of how much the solar panels are generating to recharge our rv batteries.
If you plan on setting your solar panels up in a set it and forget it style by installing them on your roof you must first think about how many solar panels realistically fit.
Can a 300 watt solar panel charge a 200 ah battery.
Area of your rv most rv s have around 280 square feet of area on their roof.
Now that you are thinking in terms of the size of the solar panel array it s time to determine how many watts of solar panels you need.
There are a lot of starter kits that include them like this one i m not affiliated just found you an example.
Clearly this kind of setup can get pricey pretty quickly.
We will be working off of that number.
This will cost you about 1 800 00 typically costs about 1 00 per watt.
How many solar panels do you need for a 2000 sq.
100 watt portable solar panel.
5 hours of direct sunlight x 6 amps generated hour 30 amp hours day.
This doesn t include the solar power needed to run anything else in the rv.
However you can use the same procedure to estimate how many are needed.
You ve already figured out how many amp hours of batteries you need from your solar power audit.
