HVV is one of the leading photovoltaic panel manufacturers in the world with leading edge technology, operating since 1956!
Sunrise Solar has selected this product due to it superior performance and the ability to have large wattage panels, which means more power with less roof space being required and $$$ savings for you!
A couple of things to remember is PANEL EFFICIENCY and THERMAL DEGRIDATION
1) HHV is about 4% than the "higher quality" panels from china which means higher performance
2) All panels are rated at STC (standard test conditions) which is a nominal output at 25 degrees. ALL panels loose a percentage power output with every dergree above 25 degrees! On a HOT day some panels can loose almost HALF of their output ability thus not producing the electricity you think they are.... HHV have minimal heat loss degridation qualities and therefore giving you a higher performing panel ALL year round producing MORE electricity for you!
3) Furthermore, we select only multi-crystalline panel from this manufacturer, which is manufacturered in a way that minimizes losses with shading. A normal multi-crystalline if shaded will cause the entire panel to shut down, where with these HHV panels, if you shade 10%..... you loose only 10% of power! (dont forget... bird poo is a form of shading!)
4) As you can see in the pictures., the solar cell is over the entire panel, unlike a multi-crystalline that has those small diamond shape cut-out's in between cells. The dimond cut-out's is due to the way they make the solar cell and is lost energy, as you ONLY produce power with cell coverage... another reason HHV panels produce more power.
