|SunPlug, the new plug and play solar kit from GoGreenSolar.com|
The SunPlug is incredibly easy to use, but that doesn’t mean that you won’t still have questions about it! Below you will find a list of answers to common questions about this kit. The most pertinent questions have been included, but feel free to leave additional questions in the comments and we’ll get them answered post-haste!
Q: Will my meter spin backwards when the SunPlug is in use?
A: Before answering this, it should be noted that most electricity meters that spin to record usage are being replaced with digital smart meters that have no moving parts. So if you have a smart meter that is “spinning backwards,” you would see an arrow pointing left to indicate that your kilowatt-hours (kWh) are being reduced because more electricity is being sent back to the grid than the home is using. That being said, one SunPlug will not generate more electricity than what the home is using. For example, if your home uses 1 kWh every hour and you’re using one SunPlug that offsets .235 kWh (235 Watts per hour) for every hour that it receives peak sunlight, then in that hour your home’s net energy usage will be .765 kWh. Keep in mind that solar panels really only produce significant amounts of energy during peak sunlight hours, and in the United States peak sunlight hours range from 4-5.5 hours per day. So if the 1 kWh per hour home had 5 235 Watt SunPlugs (totaling 1175 Watts per hour or 1.175 kWh/hour) then the meter would “spin backwards” for the duration of peak sunlight hours, but that extra energy that was sent back to the grid would just go to offset part of the home’s usage at night.
Q: How many SunPlugs can be used on one branch circuit?
A: Circuit breakers on residential homes typically have 20 Amp branch circuits. Rather than breaking down the math, suffice it to say that it’s recommended to put no more than 7 Sun-Plugs on one branch circuit. If a circuit has 7 kits plugged in, make sure that nothing else is on the circuit or the breaker will flip.
Q: Will the SunPlug still work during a power outage?
A: This model of the SunPlug uses a grid-tied micro-inverter to change the DC electricity produced by the panel to AC, which is what your house runs on. If the grid is down, then the Sun-Plug will not send electricity back to the grid or your house (it would be illegal and dangerous for it to do so).
Q: How much will the SunPlug save off of my electricity bill?
A: This answer will vary household-to-household based on your local utility rates and personal energy consumption habits. Remember that some utilities charge a flat rate for electricity while others have a tiered system where you pay more per kWh the more power that is consumed (see “How to Read Your Electric Bill” for more information on tiers). The equation to figure out how much will be saved is as follows: (# of SunPlugs) x 235 Watts x (1 kWh/1000 W) x (cost per kWh) x (hours of peak sunlight per day) x (# of days per billing period) = $ saved per billing period.

Well that’s it for the major questions that we’ve received. Please feel free to leave any further questions in the comments. Where can you see yourself using the SunPlug?
