5kw residential grid connected PV system for romania. The project has used SpolarPV 166mm 380W high-efficiency solar panels. Assembled with multi-busbar PERC cells,the half-cell configuration of the modules offers the advantages of higher power output,reduces BOS cost effectively. Special half-cell design reduces the energy loss caused by shadows,better anti-shading performance. Lower hot spot risks due to half-cell layout,offers an additional level of safety. 1500V DC voltage of the system,reducing the cost of the system side. The overflow tank is waterproof with double layers,and the cross section contains hooked aluminum frame,which enhances the mechanical load strength by 10%. Passed the certification test of 5400 Pa snow load and 2400 Pa wind load. 

A grid-connected photovoltaic system, or grid-connected PV system is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. The main advantage of a grid connected PV system is its simplicity, relatively low operating and maintenance costs as well as reduced electricity bills. The disadvantage however is that a sufficient number of solar panels need to be installed to generate the required amount of excess power. SpolarPV provide custom service to fit your house, and allow you great independence and energy savings. Our residential PV systems are simple, cost effective, easy to maintain.
