How big a household solar power system can be installed on an idle roof? -Solar street light manufacturers

With abundant solar energy resources, the annual irradiation time is about 2,200 hours. From a geographical point of view, it is still more suitable to install home solar power systems. With the support of national policies, many people consult with high enthusiasm about the installed capacity of home solar power systems. It's a commonplace question, and it's not a question that can be explained in a sentence!

The aspects to be considered when installing a household solar power system:

Need to consider the owner's electricity consumption

Need to consider the area of u200bu200bthis roof

Need to consider the orientation of the house, etc.

Of course, it is ultimately determined by the area of u200bu200bthe roof

Speaking of roofs, let’s talk about the current domestic roof types:

Cement roof, color steel plate roof, tile roof

The angle of installed capacity: horizontal roof, sloping roof

So how to calculate the installed capacity of the horizontal roof?

As the name implies, the roof is flat. When laying photovoltaic solar power panels on this type of roof, you need to pay attention to the following:

1. Support the construction of brackets, and set the inclination angle according to the sunshine conditions.

2. Because of the inclination, pay special attention to the distance between the front and back and left and right of the photovoltaic solar power generation panel to avoid blocking

Industry calculation method: 50 to 70 watts of photovoltaic solar power panels can be installed on a horizontal roof of one square meter.

Next, let’s talk about sloping roofs, which cover color steel roofs and tile roofs. When installing photovoltaic solar power panels, it can be laid seamlessly according to the inclination of the roof.

Pay attention to the following:

1. No need to lay supports and calculate inclination. It can be laid according to the inclination angle during installation;

2. Because the installation on the roof of tile or color steel plate needs to consider the load-bearing weight of the roof and the waterproof measures of the roof.
