Solar energy is growing each year, in developing countries most people are installing solar panels, this makes countries more energy independent and also helps to lower carbon footprint and improve our environment.
The key component of solar energy is a solar panel, today we are going to take a look at the 350 watt solar panel, we are going to explain everything from the dimensions, the energy production, and everything in between.

350 watt solar panel specifications
Here are some of the specifications for the 350-watt solar panel, we are considering the average size, efficiency, and weight.
What is the size of 350 watt solar panel?
The average size of a 350 watt solar panel is approximately 67 inches long and 40 inches wide. Monocrystalline modules with this power range have 60 or 72 cells, but polycrystalline panels have at least 72 due to lower efficiency.
What is the efficiency of the 35ow solar panel?
The efficiency range of 350W solar panels lies between 15 and 22% depending on the manufacturer and the technology used in manufacturing the solar panel.
What is the weight of a 350w solar panel?
350W solar panels tend to weigh about 40 lbs.
A single 350W solar panel is rated to produce 350 watts of power, but the actual power output you see from your panels depends on many factors, including, the solar panel efficiency, the temperature, shading, and the tilt of your panels.
The number of solar panels you will install depends on the amount of electricity you want to generate and the space available for solar panels.
It is not possible for just one solar panel to run all your appliances at once, if that is the case you need to figure this out by performing a simple calculation.
Step1: Find the total amount of watts needed.
This is simple, all electronic devices have a power label that will show how many watts they consume, read those labels in all the devices and add that number to find a total of watts needed.
Step 2: Consider the power loss
We wrote about the power loss due to inverters and wires, you need to take into account this when estimating the number of panels, in my experience the power loss will be around 10% for small projects and 20% for bigger projects.
Since this is a small project just divide the number you got in step 1 by 0.9.
Step 3: Find the exact number of panels you need
In step 2 you were able to find the correct power you need after taking into account the power loss, now you need to divide that number by the power produced by the solar panel and round it to the nearest whole number.
For example, if in step 2 you got 3000 watts if you divide by 350 watts as per step 3, the answer is 8.57 but you can not have 8.57 solar panels, this means you will need 9 solar panels for your project.
Are 350-watt solar panels right for your solar installation?
350W solar panels are near the average wattage of panels used for solar installations and will make sense for many property owners.
please contact your local solar installer and discuss more options available and figure out which solar panels do you need for your home.
Can I use a 350 watt solar panel without a battery?
Yes, you can use a 350-watt solar panel without a battery, just make sure that your solar panel system is connected to your utility grid (grid-tied system).
The reason for this is that solar panels will not produce energy during the night or on cloudy days, so if you do not have batteries for energy storage, you need to have a grid to power your house at night or on cloudy days.
What size battery for a 350-watt solar panel?
Can a 350-watt solar panel charge a 12-volt battery?
Yes, a 350-watt solar panel can charge a 12v battery, the amount of time it will take to charge it will depend on how discharged was the battery and the number of maximum sun hours.
If you have a 100Ah, 12v battery, that is 1200 watt-hours, at maximum conditions, a 350-watt solar panel will take 4 hours to fully charge, but if we consider power loss and other factors I would expect it to take up to 4.5 hours.
What size inverter for a 350-watt solar panel?
In order to calculate the size of your inverter, you need to take the power output of your solar panel and multiply it by a 1.2 factor. You need to pick an inverter that has the power capacity above that answer.
An inverter of 500 watts that can convert 12 DC to 220 AC, can work with the 350-watt solar panel without any issue.
Note: If you are from a country that uses 110 Ac, just pick a 500 watts inverter that converts 12 V DC to 110 V AC.
