Does Amp Adds Up With More Solar Panel

John smith is a homeowner in california looking to reduce his electric bill by going solar and he decided to call an installation company that he found on the internet.

Does amp adds up with more solar panel. With the solar panel connected to an electrical circuit measure the voltage between the positive and negative terminals of the solar panel. With 10 batteris your only option is 24 volts or 5 parallel strings. Problem is 10 batteries do not fit for 24 or 48 volts. But it does cover a big chunk of the cost of buying and installing home solar panels.

What does the display on my charge controller tell me. At 12 volts the most panel wattage you can have is 1000 watts with an 80 amp charge controller. In arranging solar panels you have two options for modifying the power output according the ohm s law. The voltage going from the solar panel to the battery.

That would allow you to use a 80 amp charge controller and allow a panel wattage up to 2000 watts. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. Check with your manufacturer though because solar panels will provide more than 12 volts under certain conditions thereby increasing the amp load resulting in beefier charge controller needs. The amperage going from the solar panel to the battery.

The panel was never designed for this and and for that and several other reasons the local utility usually will not allow it. All zamp solar charge controllers except for our 8 amp charge controller have a large digital display that shows you the following information. So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps. The next day a rep from xyz solar came out to his house and after looking at his electric bill told john that he would need an 8 5kw pv system to offset 100 of his past 12 month usage.

You can either wire multiple panels in series to increase voltage with current amps remaining the same as any one panel or wire the panels in parallel to increase current with the voltage output remaining the same as any one panel.
