Frequently Asked Questions (FAQ)
What can a 400W solar panel power?
How many 400W solar panels do I need for a home backup system?
• 2 panels = 800W solar array
• 4 panels = 1600W solar array
• 8 panels = 3200W solar array
• 10 panels = 4000W solar array for larger backup systems A larger solar array allows you to recharge batteries faster and better support off-grid or home backup applications.
Can I connect multiple 400W panels together?
Do I need a battery and inverter for my solar panel system?
Is this panel compatible with LiFePO4 batteries?
What size inverter do I need for a 400W solar system?

Customer Reviews
This was exactly what I needed. I'm using the Dokio Solar Panel on the roof of my rv carport. Ever since I started parking the rv under the carport the solar panel on the top of the rv obviously cannot be utilized to re-charge my batteries and run the lights and slides. It is installed now, and with a reverse polarity plug and cables from Amazon, I was able to plug it directly into my side solar panel extended plug.
This solar panel meets my expectations. I will recommend friends and families about this solar panel.
Great value at a very competitive price, except others charge a hefty shipping fee in addition while Dokio’s price offers FREE shipping. The high output voltage also works well with my plugin micro inverter so I can plug a single panel per channel vs having to connect 2 separate panels in series to get the higher voltage required.
Great experience, from ordering until using it. Performs to specs. Great price with free shipping. Would buy again
These panels are great for the cost. Shipped pretty quick as well, no issues with packaging, the mounts for them are easy to setup and install them on. I built mobile platforms to install these on so I can move them around my yard. I have seen as much as 1360 watts from the 4 panels so far (running them in a series of two then in parallel to my power station).
