Like apples and oranges, but I'll give it a try! Let's compare it with a 3000 Watt gasoline powered generator. First, the 3000 Watt generator is not rated for constant use, maybe 60% duty cycle, meaning that it can only produce 1800 Watts (3000 X .60=1800) continuous. Then we might consider elevation---where we are in New Mexico is over 6,000 feet. That reduces the generator power by about 25% more. Hmmm, we're down to 1350 Watts maximum (1800-450=1350) that it can produce continuously, with some ability to handle some short bursts above that.
Ok, let's say we run the generator for 4 hours a day. It should produce about 5400 Watt/Hrs. of total power (1350 Watts X4 Hrs.) That is approx. what the solar panels would produce in a normal day. BUT, the PowerGenX system has storage batteries that store enough power to provide up to 3000 Watt/Hrs. during the night (or a cloudy day).
Sooo, our unit produces about the same amount of power in a day that a 3000 Watt generator produces in 4 hours (no fuel, of course.) It (PowerGenX) can handle slightly larger peak surges and can spread that power over a longer period. For example, it can keep your refrigerator and freezer cool 24/7 (they don't run continuously) and take care of lighting, etc. at night as well. BUT, the generator uses about 2 gallons of gasoline and costs (at $4.00/gal.) $8.00 per day to run (and requires maintenance and doesn't last very long either---).
Hope this makes sense. I told you it was apples and oranges!
There is a 30% Federal tax credit for the purchase of alternative energy equipment. Some States also offer tax credits or other incentives. In New Mexico, there is a 10% State tax credit. It's best to check with your tax advisor for available incentives and how they may be applied to your situation.
Wind systems require a battery and/or inverter system in order to function. The PowerGenX unit has all the basic components EXCEPT the wind turbine and its charge controller, so it's quite simple to add.
Of course. There are several ways to use the free extra power that your power plant provides. First might be simply to plug in some appliances, tools, or other items that you routinely use. Next might be to isolate specific circuits in your home or business and wire them so that you can transfer them to your PowerGenX when it is producing excess power. You might need an electrician or technician in order to do this safely. Another way could be to install a plug-in grid tie inverter which automatically runs the excess to your loads or into the power grid. You can find these inverters online at minimal expense, but some are not UL approved and should be researched before you try them.
The solar panels present a large flat surface (sail) to the wind, and can upset the whole apple
cart (so to speak.) If you normally have wind, then you should tie the unit(s) down with small cables or ropes to two or three ground anchors. Anchors can be stakes, bolts in concrete, or even heavy objects that can't blow away.
All of the electrical equipment, trailer and cabinet have standard manufacturers warranties. PowerGenX also provides warranty for the system mounting and wiring for one year from date of delivery, If a problem exists that requires our attention, unit must be delivered to one of our service centers, where it will be repaired or replaced at our option.
This is a loaded question, and the answer is --- it depends. Our experience in the solar and wind energy field leads us to believe that conventional lead/acid batteries provide more bang for the buck than AGM (absorbed glass mat) or gel. While it's true that AGM batts can have slightly better charge/discharge characteristics, and don't require adding water, we've found them to be a LOT more finicky than conventional wet cells. They seem to require very specific charge voltages and don't seem to hold up as well when deep cycled. They also cost several times as much per A/H (amp/hour) as conventional batteries.
Conventional batts seem to be more forgiving of overloads, improper charge conditions, and deep discharges, HOWEVER, they do require routine checking and filling with water. Soooo---if you have a well regulated system that you don't deep cycle, and you want to pay four times the price for not having to add water---buy the AGM batteries. But if you want max power per dollar and don't mind checking on them occasionally, save a few megabucks and go with conventional. I would recommend a good quality unit, such as Trojan or Deka---don't try to save pennies when it may cost you dearly later!
For a MUCH more detailed discussion go to some of the solar battery sites and read through the specs and discussions. . .
Two reasons---one is because the high output voltage solar panels require it. Regular charge controllers connect the solar panels directly to the batteries until the batteries are charged, then disconnect. This only works when the panel voltage produced is close to the battery voltage. MPPT controllers sample the battery and solar panel voltages and currents and determine the maximum power point, where the best power transfer occurs. This brings us to reason number two---MPPT controllers are up to 30% more efficient than conventional controllers, because of this constant monitoring and adjusting of the voltage/current (power.)
Most of the lower cost solar systems use modified square wave or modified sine wave inverters. Both of these types can be very unfriendly to your delicate electronic equipment and can cause motors to overheat. Sine wave inverters provide clean, safe power that is often better regulated than utility power. It's true that these inverters cost more, but we believe that our customers understand the difference and prefer the safer alternative.
