INTRODUCTION
The small type solar grid tie
power inverter can obtain the solar energy from 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
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, it can be
standardized according to the actual using.
The AC output of the inverter can be connected to home grid
directly, when the home grid is run by the conventional electric
network. The small grid tie inverter 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 using
the current controlled PWM method 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
output 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.
