There are many advantages of Small Grid Tie Photovoltaic System compare with the traditional grid tie system.
1. Low cost and easy installation - Small Grid Tie Photovoltaic System 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's very low maintenance costs.
2. Free combination - Small Grid Tie Photovoltaic Systemcan be used as a separate grid tie system and can be setup as a large solar array with many of them. The quantity of Small Grid Tie Photovoltaic System 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 panel and if the total power of the solar panels exceeds the allocation grid inverter, it is necessary to increase the cost of a grid inverter.
3. Combination of Small Grid Tie Photovoltaic System does not interact - The traditional solar grid tie inverter 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. If the performance of a piece of solar panels in the system degrades, this just effects this piece itself, will not affect other Small Grid Tie Photovoltaic System in the system.
4. Improving 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 Small Grid Tie inverter Photovoltaic System has no such disadvantage. Because every inverter of Small Grid Tie Photovoltaic System 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.
