INTRODUCTION
The small type solar grid tie
power inverter can obtain the solar energy from the solar panel,
and can connect to the grid through its output cable with no extra
equipment. The installation is very convenient and reliable. We
call the system combining with small solar grid tie power inverter
and the solar panels as‘SGPV’. The system includes solar panels and
small type grid tie power inverter. Solar panels can be mono
silicon,polygon silicon, non-crystal film or any other material
that can transform solar energy to electric energy. The power of
grid tie inverter should be matched to the power of solar panels
connected. So the power of SGPV is defined by its solar panels, and
it can be standardized according to the actual using.
The inverter can be connected to any outlet at home, when this line
run by the conventional electric network.The small grid tie
monitors the volume, frequency and phase of the home grid, then
produce a pure sine wave that the frequency and phase are as same
as the grid's, and the volume is a bit higher than the grid's, then
according to the current controlled PWM, to control the output
power to the grid. The small grid tie inverter just puts out power
when the home grid is on.
When the sun shines, the PV panel will produces DC voltage, and the
grid tie inverter will change the DC voltage to AC voltage and puts
out power to the home grid. When the total power of electric
apparatus that are using in the house is larger than the output
power of the inverters, these power from the inverters will be
consumed in the house, which will slow down the power meter,
otherwise, the difference of the output power of the inverter
between the total used power of the apparatus will go out from the
house to the out grid.
ADVANTAGE
There are many advantages of SGPV,
compared with the traditional grid tie system.
1. Easy installation and low cost - SGPV can make full use of all
types of buildings’ surface that face to the sun in the city and
can be installed on that building surface. Besides, the maintenance
cost is very low.
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. If you are planning to install a grid-tie PV system, in a
general way, the solar array and inverter need to be carefully
matched to ensure that the inverter’s voltage and power limits are
not exceeded. When you want to increase more solar panels, and if
the total power of the solar panels exceeds the allocation grid
inverter, it is necessary to increase a grid inverter which is much
more expensive.
3.Combination of SGPV does not interact - The traditional solar
grid tie system, they offer units ranging in high power output and
these units are modular so you can have multiple units operating in
parallel for large solar arrays. 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 a piece of solar panels
in the system, for some reason, such as leaves, bird droppings,
dust, shadow, etc.,degrades, the performance of the entire solar
power system will decrease. SGPV has no such disadvantage. If the
performance of a piece of solar panels in the system degrades, this
just effects this piece itself, will not affect other SGPV in the
system.
4. Improve the efficiency of the entire solar power system – In
traditional grid tie system, the 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 panel 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 of
the entire system.
