Advantage of The Sunshine Grid Tie Power System
There are many advantages of SGPV compare with the traditional grid tie power system.
1. Low cost and easy installation - SGPV can make full use of all types of buildings’ surface
that face to the sun in the city as well as fast and easy installation of solar modules and grid tie
inverter. It just needs very low maintenance costs.
2. Free combination - SGPV can be used as a separate grid tie system and can be setup as a
large solar array with many of them. The quantity of SGPV in the array is just according to your
desire.
3. Combination of SGPV does not interact - The traditional solar grid tie system is alway
connected with many panels, and those solar panels are connected in series, so the input
voltage is very high,although, the traditional grid inverter has MPPT feature (Maximum
Power Point Tracking), but the maximum power point is according to the entire series in
terms of solar panels array, if the performance of one piece of solar panels in the system, for
some reason, such as leaves, bird droppings, dust, shadow, etc. and degrades,
performance
of the entire solar power system will decrease.
SGPV system has no such disadvantage. If the performance of a piece of solar panels in the
system degrades, this just effects one SGPV, will not affect other SGPV in the system.
4.
Improving the efficiency of the entire solar power system – In traditional grid tie system, many
solar panels are connected in series, so the MPPT of the inverter is according to the total
panels in series, not to every panel, but there is difference between every panel, so not every
panel is working at the maximum power, this will reduce the total power of these panels
in series.
But SGPV has no such disadvantage. Because every inverter of SGPV has MPPT function, so
every panel is working at the maximum power, this will increase the efficiency of the entire
system.
5. Low power consumption – Most of the parts in the small grid-tie inverter are digital ICs and
low power MCU, so the power consumption of it is low, though the quantity of grid tie inverters
is increased, but this will not increase the power consumption much of the entire system.
Multiple inverters can be connected in parallel to creat bigger system.Plug and play installation.
