Producing more electricity than you use?

Is it true that a new system is not allowed to produce more electricity than the previous calendar year ? I'm guessing its due to the loss in tax revenue?

This is not true at all. If you system underproduces in the first year due to a heavy snowfall in the winter, no one is going to punish you in the second year when it produces more! There is no direct tax impact to solar energy production.

Here in NJ for net metering you can't design a system that is projected to produce more power than you have consumed in the past 12 months. If you do - you will need a load calculator filled out and sealed by a PE in the state. The actual output of your system once constructed has no limitations - if it produces 25% more than projected than that is fine. Keep in mind that having too much electricity doesn't benefit you because the utility will only true you up annually at a wholesale rate vs. a retail rate. For instance if you generate 1,000 extra kWh you will get only 5 cents or $50. However, if that same 1,000 kWh offset usage you were paying for at retail 18 cents - it has a value of$180. Keep in mind that the extra system you installed had a linear extra cost but when you produce too much electricity the payback is at 5 cents not 18 cents. Now in other parts of the US the rules may be different. We know someone in Minnesota for instance and they can build (residential) a system up to 40 KW regardless of their consumption. This is second hand and the details may be off - but each state has its own rules.
