Why We need use solar energy
Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy.
Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications.Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation. Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country.
The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have a lifespan of roughly 30 years, and come in variety of shades depending on the type of material used in manufacturing.
Basic structure of solar panel
What material is used in frame of solar panel?
Today we would like to take some time to share what material is used in frame of solar panel? Firstly let us have an idea of solar panels and the function of solar frames. From the picture of solar panel material breakdown as below, we can see that solar panel frames are part of solar panels. It hugs the glass covering the top and the solar back sheet at the bottom.
Functions of solar panel frames
There are three major types of solar panels: monocrystalline, polycrystalline, and thin-film. Each type has its own unique advantages and disadvantages. Cause thin-film do not need frames, so our topic is on mono and poly solar panels. The frame – a mechanical role and component to solar panels. The functions of solar frame lies in its mechanical characteristics that bring several benefits: 1. Handling, 2. Storage, 3. Grounding, 4. Fixation, 5. Resistance against mechanical load such as wind, snow… Frames are a key feature in the design of a solar panel. They help to hold different components together, offer protection against the elements, and help to improve durability. Most solar panel frames are made from either anodized or powder coated aluminum in past many years.However, since aluminum is relatively expensive, more and more projects use iron instead, which greatly reduces the cost of investment
Why Does it matter if solar module frames are made of steel or aluminum?
A reckoning is upon us.Climate science shows that deep decarbonization of the electric grid, transportation sector and heavy industry is the only path forward.The PV industry isn’t as ready for the transition as you might think, because of an often-overlooked component, the solar module frame. Using aluminum for module frames contributes more than 14 kilograms (kg) of greenhouse gas emissions (GHG) per 1 kg of aluminum. Steel production results in about 1.2 kg of GHGs for every 1 kg of steel.Switching to steel module frames will deliver more than 85% reduction in GHG.In addition for steel frame, the strength value, elastic modulus (stiffness), melting point and tear resistance of steel are far greater than that of aluminum frame.
What we can do?
Saibo Science & Technonolgy,After in-depth market research and study, we designed a variety of solar bezel models, including open and closed design.which have been very warmly welcomed and widely used at China and overseas. At the same time, we can also customize products according to customer requirements.following is some designs for your reference:
