Solar Panels

Solar panels convert solar energy into electricity. The electricity produced by solar panels is in the form of Direct Current or (DC). On home applications such as Grid-Tied, it is necessary to add a microinverter which turns the DC electricity into usable (AC) or Alternating Current into your electrical panel for your regular household electronics. When excess electricity is produced by your panels during the peak hours of the day, the microinverter will start sending all that extra power back to the grid and through a program called NET METERING your account would be credited with any extra power being produced to reduce your electric bill.

On off-grid applications such as off-grid homes, marine or RV, the (DC) electricity produced by the solar panels will usually go through a solar charge controller and then into a battery bank for storage. To use regular (AC) appliances in an off-grid solar system, the stored power in the battery bank must then be turned into (AC) electricity through an inverter.

Solar panels vary in sizes and can be wired in series or parallel.

When installing solar panels in series the voltage is additive, but the amperage remains the same example. If you installed 4 solar panels in series and each panel was rated at 12 Volts and 5 Amps, the entire array would be 48 Volts and 5 Amps. 

When connecting the same panels in Parallel the Voltage would remain at 12 Volts but the Amperage would increase to 20 Amps

The advantage of one over the other is system specific, but in parallel the voltage remains the same and the amperage is increased, and in series the amperage remains the same and the voltage is increased. If you need more voltage you might want to go with a series type wiring, if you need more amps you can go with parallel.

Note: Because of size, larger Solar Panels require freight shipping. Please call us at 888-627-3029 for specific shipping rates.
