How to build a home solar power station
PV power plant from the project - Design - Construction - the whole process of grid operation, and with instructions. In view of how to effectively control costs, improve the rate of return is the core concern of investors, the first phase of the construction cost of photovoltaic power plant investment projects naturally become the focus. The photovoltaic power plant as a long-term investment in the operation of the project, the overall stability of photovoltaic power generation system for 25 years should pay more attention to the reliability of the operation.
2 charge controllerIn the solar power system, the basic function of charging controller is to provide optimum charging current and voltage for battery, fast, stable and efficient for battery charging, and charging process to reduce loss and prolong the service life of the accumulator; protect the battery at the same time, avoid excessive charge and discharge phenomenon. Advanced controller can record and display all kinds of important data, such as charging current, voltage and so on. The main functions of the controller are as follows:1 overcharge protection to avoid battery damage caused by high charging voltage.2) over discharge protection to avoid battery damage due to discharge to the low voltage.3 anti reverse connection function to avoid the battery and solar panels can not be used because of the positive and negative polarity and even lead to accidents.4 lightning protection function to avoid damage to the whole system by lightning.5 temperature compensation is mainly for large temperature difference, to ensure that the battery is in charge of the best results.
1 solar cell moduleThe solar cell module is the core part of the power generation system, and its function is to convert the radiant energy of the sun into direct current. According to the needs of the user, a number of solar panels will be connected in a certain way, the composition of the solar cell array (array), coupled with the appropriate support and junction box composed of solar modules.
Knowledge of their own construction needs:Solar power generation system mainly includes: solar cell module, controller, storage battery, inverter, load and so on. Among them, the solar battery module and the battery is the power system, the controller and the inverter are the control protection system, the load is the system terminal.
