Know How Solar Panels Work
"Most plentiful, accessible, and least expensive power source in the world."- Danny Kennedy
Fossil fuels are steadily declining due to global warming. With such extreme environmental conditions, the fluctuating oil and coal prices are difficult to predict. To make sure that you do not pay sky-high prices for necessities such as electricity, solar energy is your best bet. Yes, the sun is the ultimate energy source, and we can all benefit by tapping into its resources.
But how do solar panels work?
How does something simple like a solar panel use sunlight to power your oven and television?

It works by absorbing sunlight with the help of photovoltaic cells that generate direct current (DC) energy. And then, with the help of inverter technology, it converts this direct energy to usable alternating current (AC) energy. Each photovoltaic cell in the solar panels is a sandwich made up of two slices of semi-conductive material, typically silicon— the same material used in microelectronics.
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.
Along with that, it is vital to understand that solar panels respond to the visible light spectrum. This means, if the sunlight is enough to see, there's sufficient light for solar panels to start generating electricity. The stronger the sunlight, the better.
Benefits of Solar Panels:
- Solar panels guarantee power when the sun shines, offering a reliable and stable form of power generation.
- They need less space than other renewable technologies and can be installed at a broad range of locations. From larger, rural solar farms that can support local biodiversity by providing a natural habitat for bees, butterflies and nesting birds to city center rooftop solar panels can help fight fuel poverty.
- After installation, solar panels need little to no maintenance. They sometimes require cleaning to keep them clear of debris and dirt.
- They also do not generate any noise pollution while generating electricity. It means that installations aren't intrusive.
- Solar panels are safe. Mostly made from silicon sheets, there's no danger of the photovoltaic cells seeping or radiating any toxins or fumes.
Two types of solar panels are available in the market - Monocrystalline and Polycrystalline. They vary according to their performance, appearance, cost, how they are made and installation purpose.
Monocrystalline Solar Panels
Monocrystalline solar panels are commonly considered a premium solar product. Better efficiencies and sleeker aesthetics are its principal benefits. Silicon is created into bars and cut into wafers to make solar cells for this type of solar panel. The use of high-quality glass and solar cell surface coating allows for excellent performance even in low-light conditions on cloudy days, mornings and evenings. EVA‚ (ethyl vinyl acetate) is used for advanced encapsulation. The encapsulate is inserted between the solar cells and the top surface and the rear surface for protection.
Polycrystalline Solar Panels
Polycrystalline solar panels commonly have lower competences than monocrystalline alternatives. They appear to have a blue hue in place of the monocrystalline panel's black shade. Polycrystalline solar panels are made of silicone, too. Instead of using a single silicon crystal, however, manufacturers melt together many silicon fragments to form the panel wafers.
Polycrystalline solar panels are also known as ‘multi-crystalline’, or multi-crystalline silicon. Because in each cell, there are many crystals, the electrons have less freedom to move. It results in lower efficiency ratings for polycrystalline solar panels than for monocrystalline panels.
Start your Solar Journey Now
The use of solar panels is a trend that is fast catching up with the masses in India after acknowledging its benefits like cost and energy efficiency, among others. However, an essential factor to consider before you leap into equipping your house with solar panels is that you choose good quality solar equipment.
So, if you're considering going solar, make sure to choose solar panels from reputed brands like Luminous. They offer the most comprehensive range of solar panels supported by the Pan India service network. Optically, mechanically and electrically tested, their high strength Aluminum frame is designed to provide high torsion resistance. With multi-layer encapsulation, these solar panels provide better module protection than others. Hence, select the right solar panels suitable for your needs and start your solar journey now!
Reuse, Reduce, Recycle. Suppose many businesses and people regard this call. In that case, our environment and this world will become a healthier, safer, and better place to stay in.
There’s an increasingly large number of households that are opting to take on solar energy. There are some very good reasons for this as well. The environment continues to suffer from our usage of fossil fuels and climate change is on the horizon
The human population is increasing day by day so there is a need for researching those practices that can feed the growing population without disturbing the ecosystem. The existing farming practices are increasing crop production but it is imparting its harmful effects on the soil, land, and water.
Have you considered how you're using water in your home? There are plenty of ways to reduce your consumption of this precious resource, but it's also important to be mindful of how the wastewater that your home produces affect the environment through the contamination of rivers and springs. Make a few changes to conserve water and try a few DIY recipes to avoid contaminating local sources while also ridding your home of harmful chemicals.
Businesses these days have their unique ways of marketing which include offering customized shopping bags with brand logo printed on it. Plastic bags were generally offered with every purchase to consumers. These plastic bags are later used as a part of everyday lives by most of the consumers.
Green energy technologies have been debated extensively over the past decade, generally being dis
