Bimetallic Solution for Solar Industry
The solar industry is one of the most flourishing sectors in India. The electricity production using solar energy is getting much cheaper and easy. The bimetallic solutions are playing a crucial role here. In this article, we will discuss how bimetallic solutions are becoming the norm in the solar industry. So without further delay, let's get started.
Generally, in the power system, aluminum cables are being used. And the bus bars in the large solar arrays are made of copper. Hence, connecting the aluminum cable to a copper busbar creates a dissimilarity of contact, and it may lead to galvanic action, higher contact resistance, and corrosion. As a solution, the bimetallic lugs are used. Using similar metals, i.e. copper with copper and aluminum with aluminum get contacted, and the dissimilar metal parts of the lug will be friction-welded. Bimetallic Lugs ensure that the joints are technically sound and durable.
In a large solar array, these bimetallic lugs play a crucial role. In the combiner box of the solar system, the output of all the solar strings combines for the inverter. Multiple cables from the solar strings get connected to a common copper bus bar. From here, the power gets transferred to the inverter through aluminum cables. Here the use of bimetallic lugs ensures that each connection is durable, safe, and efficient.
Bimetallic strip for solar tracking
Throughout the day the sun changes its direction, so the solar panels should change their angle too. The bimetallic strip can sense the temperature change, and it switches the direction of the solar panels accordingly. Using the bimetallic strip the solar tracking becomes automatic. The utilization rate of solar energy increases, and the loss of energy decreases.
Bimetallic nanogratings in solar cells
Many times due to less thickness, the thin-film solar cells suffer from poor power absorption. But with the use of nanogratings of Al–Cu, the absorption efficiency improves. Using these nanocoatings the solar cell absorbs light for the long-wavelength region (670–1060 nm) with an average simulated absorption rate of more than 70%. Other crucial variables such as photocurrent density, small incident angle insensitivity, tunability, and structural parameters tolerance show remarkable improvement.
The bimetallic solutions are helping the solar industry in every other aspect. Here we have discussed a few of the major ones.
