200 liters of solar charging

Approximately 200 kg. Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. The solar load of 200 liters is approximately 200 kilograms. Load refers to external force and other factors that cause internal force and deformation of a structure or component. Or again, it is usual to refer to various direct effects exerted on works of art to produce effects on the works of art or their components.

What are the requirements for the material, size and orientation of my roof for solar power generation? (What are the roof requirements for installing a roof system?th of domestic solar energy production?)

An expert answer. Guaranteed to be correct.

Dead load

1. The bulk density of concrete is 25, but the bulk density of reinforced concrete should be 26.5, because the bulk density of steel bars is 78, and when mixed together it is slightly higher than 25 'High-Tech Regulations' require the thickness of roofing panels to be not less than 120 and not less than 100, so they are all based on 120. This is 26.5x0.12=3, 18

2. It depends on how your roof is made. If there is a surface layer of 30, then it is 0.03x20=0.6

3. . Wipe the bottom of the board Gray 0.02x20=0.4

4 If there are tiles on the roof, it's 0.2. There are also waterproofing, thermal insulation, etc. It depends on the materials used.

5. Since the roof has a slope, all loads must be divided by the cosinefrom the angle and fall onto the projection surface. Have you thought about this?

6. In real projects, if there are lightning rods, decorative columns and solar power on the roof, the load will be much larger. Especially for solar water tanks, it usually takes 0.5

For a project I just worked on, the dead load was estimated to be 6.

You need to therefore understand that the roofing method determines the weight of the roof. It’s up to you to decide how to build the roof. It doesn't have to be 5, but 5 is enough for normal projects.

If you have any questions, ask them.

What should you pay attention to when installing solar energy?

Solar energy has no requirements for roof material. Concrete, colored steel tiles, glazed tiles, asphalt tiles, etc. be installed. Different slabs are equipped with different solutionsmounting brackets and mounting brackets.

The direction of the roof depends on where it is located. Different places have different longitudes, latitudes and lighting directions, so specific analysis is needed. For example, in the Zhejiang region, a tilt of 22 to 24 degrees toward the south is the best angle for generating electricity throughout the year. The loss can be calculated based on the tilt angle. In winter, the energy produced on the west side is approx. 88-93% of the power generation on the south side and on the north side the power generation is around 88-93%. Installation is generally not recommended.

As for the size of the roof, 1 kilowatt requires approximately 8 square meters of space.

What should you pay attention to when installing a solar water heater?

Solar water heaters fully absorb the sun's energy and convertweave light energy from the sun into thermal energy to heat the water temperature. When choosing the installation location of the solar water heater, you should choose a sufficiently sunny place and a stable location. It's best not to be blocked by buildings or trees in winter. Generally, vacant places such as balconies, roofs and roofs are chosen.

Water heaters that use electricity as energy for heating are often called electric water heaters. It is one of the three main water heaters, alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to heating power: water storage type (also called volumetric or thermal storage type), instant heating type and instant heating type (also called semi-water storage).

What soundt precautions for installing solar cell modules

Conventional methods of installing solar modules include mounting holes, pressure blocks, and trunking. Different installation methods will meet different external load requirements. No matter how solar modules are installed on the roof, the bearing capacity and waterproof performance of the roof should be considered. Installing the photovoltaic system on the roof will increase the constant load of the roof, which requires the building. design unit to check the bearing capacity. The additional photovoltaic system on the roof can reduce the cooling/heating load of the building to a certain extent, thereby reducing the energy consumption of the building.

During storage, transportation and installation of photovoltaic solar cell modules, no collision ordamage is not permitted. Particular attention should be paid to prevent damage to the module glass surface and backsheet material. directly impacted by hard objects. The solar cell modules must be free from deformation and the glass must be free from damage, scratches and cracks. At the same time, you should pay attention to installation problems during installation

1. It is strictly prohibited to install solar modules in extreme weather conditions;

2. Connect the positive and negative poles of the same connection line of the solar module. Quick connect;

3. It is strictly forbidden to touch the live metal parts of the solar module string;

4. Only solar modules of the same size, specification and model can be connected in series;

5. It is prohibited to use the solar module backsheet (EVA) if itis damaged;

8. The battery panel unpacked at the job site must be placed face up. There is a wooden pallet or battery board packaging at the bottom. It is strictly prohibited to place it vertically, tilted or suspended. in the air. It is strictly forbidden to directly expose the back of the module to the sun;

9. It is strictly forbidden to step on the panel to avoid damage to the module. Personal injury; it is strictly prohibited to squeeze or use sharp objects to hit, collide with or scratch the tempered glass of photovoltaic modules;

10. Components with open circuit voltage greater than 50V and composants with a maximum voltage of 50 V. The rated voltage of the system exceeding 50 V must be connected before the component is connected. There must be obvious warning signs of risk of electric shock near the appliance.
