The installation and use of solar off-grid systems have become very common. They are not only environmentally friendly, but also solve the problem of electricity consumption in remote areas without electricity or high electricity costs.
Although this small off-grid system is simple in design and installation, it is actually a technically demanding job. In addition to choosing a photovoltaic brand with good performance, professional construction workers are also required to install it.
1. Reasonable site selection: Choose a place with sufficient sunshine and no obstructions. Of course, pay attention to the azimuth and tilt angle to ensure that the photovoltaic panels can obtain maximum light.
2. Consider climate factors: Choose heat-resistant, cold-resistant or wind-resistant photovoltaic components according to local climate conditions.
3. System capacity matching: Reasonably configure the system capacity according to the power demand and the power generation capacity of the photovoltaic panel to avoid overload operation.
4. Installation of the bracket
The solar photovoltaic bracket is a special bracket designed for solar photovoltaic power generation systems. The stability and firmness of the bracket placement are the most important. It is necessary to use materials with high strength, corrosion resistance, no rust, and strong bearing capacity. Local weather conditions, such as natural environment, disaster weather, and wind and rain levels for many years, must also be considered.
5. Routing design
The installation master will carefully design the wiring distance. When wiring, you must pay attention to the distance and position of the bus box. Under normal circumstances, the wiring should be as short and even as possible, and the terminals should be firm to prevent virtual connection or disconnection.
6. Controller
Although the controller generally has corresponding power distribution protection measures, you should also pay attention to prevent polarity reversal, short circuit and other phenomena during the wiring process to avoid unnecessary trouble. If your controller is not waterproof, you must pay attention to the angle and position when choosing to place it to avoid rain immersion.
7. Maintenance convenience: Choose an installation location that is easy to clean and check to ensure long-term stable operation of the system.
8. Safety measures: Install a lightning protection system to ensure the safety of the photovoltaic system in thunderstorms.
I hope this article can help you learn more about photovoltaics and help you use your own off-grid system as soon as possible.
