Designing a Grid Tie Solar Power System for Your Home
Today we will introduce a home solar power system design below 10kW, which is installed on the roof of the house and connected to the grid of 220V or 380V. The maximum installation capacity is 25% of the capacity of the upper-level transformer. First of all, it is required to determine whether the load capacity of the roof can meet the requirements. The loading requirements of the solar power system equipment for the roof are greater than 30kg/m2.
How Much Electricity Does a Home Solar System Produce?
If you plan to design and install a grid tie solar PV system for your home, you will want to know how much electricity the system can produce each year. Now we will take the roof of 60m2 as an example to make this calculation. At present, the household solar power system generally adopts the monocrystalline silicon solar panel and polycrystalline silicon solar panel. Its specification is generalized as 36V 280W, and the single piece of solar panel generally has an area of 1.8 m2...
How to Troubleshoot the Wrong Wired On Grid Inverter?
As to the photovoltaic grid-tie inverter, the input end is connected to the photovoltaic component and the output end is connected to the power grid. The component has only positive and negative poles, and it is not easy to wire incorrectly. Since the component is a certain distance away from the inverter, it is required to add an extension cable. The correct connection method is that the photovoltaic connector has a female connector on one side and a male connector on the other side, so that the positive and negative directions will not change. However, some green hands will also make the two connectors of the extension cable the same. If the power inverter is connected, the positive and negative poles will be reversed.
