Easy to install AFFORDABLE solar technology.
GreenRay Solar offers amazingly simple, inexpensive solar panel technology for your home or business

Not everyone gets excited about the idea of installing solar panels at their home or business. Sure, solar panels may help to cut costs in the long run and establish some level of "off the grid" self-sufficiency, but they are typically expensive and require complex installation and maintenance efforts. But GreenRay Solar, a Westford, Mass.-based solar company, has developed a revolutionary new integrated, simplified solar technology called the SunSine AC Module that produces up to 25 percent more energy than most current technologies, but at a fraction of the effort and cost.

Each SunSine panel is its own individual appliance, in other words, working fully and completely by itself. But the panels can also be attached to one another very simply, and operate at full capacity in a network as well. In contrast to most DC systems that have to be specially configured based on size and climate to power a single central converter, GreenRay's system works optimally whether you have one panel or 20 panels, and in any climate conditions. Once attached to the main electrical distribution panel, SunSine AC Modules are configured to good to go right out of the box.

Just imagine, affordable solar power ready to use right out of the box, just plug it in to your home's power system and its ready to go. I'm sure its not quite that simple but, it beats paying out for the wazoo for some electrician to install some whole complicated DC to AC power rectifying system.

The thing I'm most impressed with is that these things put out AC power!
That eliminates expensive batteries,to store unused energy and expensive voltage rectifiers to change the DC to AC power.
Looks pretty sweet.. However, bear in mind, with an AC output you cant store excess electricity in normal batteries. So these would not work in an "off the grid" situation unless you installed an inverter to convert to DC current for storage.. As is, they would simply feed the excess power created back into the grid, reversing your electricity meter and thereby reducing your net power bills. However, you would still need to take power from the grid at night time.
Well that's my impression from a quick glance.. great find however and if the price is right, definitely worth a look.
Next to useless for people that want to go off the grid.

When i go solar it will be on a motor home and i will be useing a 48 volt system and inverter.
48 volt inverters are cheaper per watt output then 12 volt inverters as long as you are not looking for pure Sine Wave inverters.
Also you want Stackable Power Inverters. This allows you to run just the out put wattage you need without the heavy battery drain of a large inverter.

The only need for a pure Sine Wave inverter is electronics like TVs or computers. you don't need a Sine Wave inverter to run lights refrigerator fans AC unit. and if you use LED lighting system you will not even need a inverter for lights

Or in the case of a computer there are special dc power supplies just for this use.

One of the big reasons solar systems are expencive is people are being sold systems that are not using system energy properly.
only use AC where needed and if you can use DC it will be more efficient.
Most of the electric appliances and gadgets in your house have to convert the AC voltage into DC to make the gizmos work. 

We use AC because its easier to transmit over long distances. DC actually is much more efficient but, because you can't transmit over a distance, it lost out to AC long ago.
A rectifier capacitor. Hook those two up and you convert AC into DC.

The proper setup is Solar Panel > Battery > Inverter > AC out

But if you want to store AC, then:
AC Solar panel > 12 Volt Wall transformer to DC > DC Batteries > Inverter > AC out

The bottom line is you don't need AC solar panels.
You just need cheap DC panels, Battery and inverter. Simple and low cost.
You could rewire the house for some 12dc outlets and use LED lighting and/or build a wind turbine?
