How do solar panels work?

One of the most exciting and cost-effective ways to power your home is through solar energy. With the help of solar panels, you can harness the unlimited power of the sun to meet your energy needs and even earn credits on your utility bills.

So how do solar panels work?

Essentially, solar panels convert sunlight into electricity using photovoltaic (PV) cells. The panels are typically installed on rooftops or other areas that receive ample sunlight throughout the day. Solar panels typically consist of silicon cells, which are sandwiched between a protective glass layer and a plastic or metal substrate. When a photon strikes a panel, it excites electrons, completing an electric circuit that generates direct current (DC). This DC current is then converted into alternating current (AC) using an inverter which is then transferred to your home.

There are various types of solar panels on the market, each with its own pros and cons, ranging from efficient but expensive monocrystalline panels to more affordable but less efficient polycrystalline panels.:

1. Monocrystalline Panels: Monocrystalline panels are a type of solar panel that has gained a lot of attention in recent years for their efficiency and sleek design. Unlike other types of solar panels, monocrystalline panels are made from a single silicon crystal, which makes them more efficient and durable. They are perfect for those who want to invest in solar solutions and live in areas that receive plenty of sunlight. With the increasing demand for solar panels, it's important to understand the different types of solar panels available on the market. Monocrystalline panels are becoming a popular choice thanks to their high output and versatile design. If you're considering a solar panel system for your home or business, be sure to explore the benefits of monocrystalline panels.
2. Polycrystalline Panels: Unlike mono-crystalline panels, polycrystalline panels are made by melting multiple silicon fragments together, forming a less uniform but more affordable panel. These panels are perfect for those who are looking for solar solutions that won't break the bank but still deliver quality results. They may not be the most efficient, but they offer a cost-effective solution for those looking to switch to solar energy.
3. TOPCon Panels: TOPCon (Tunnel Oxide Passivated Contact), a rapidly growing cell technology that is capturing a larger share of the market. Belonging to the N-type cells, TOPCon technology uses innovative methods to enhance electricity production in solar cells. Unlike traditional P-type cells, TOPCon cells are doped with phosphorus instead of boron. This means they are not susceptible to degradation from oxygen, offering a significant advantage. Phosphorus doping also boosts efficiency by adding free electrons to the wafer. Introduced in 2013, TOPCon cells have recently gained widespread adoption by manufacturers since 2019. Explore the future of solar energy with TOPCon technology.
4. HJT (Heterojunction) panels: HJT (Heterojunction) solar panels are a type of solar panel that combines traditional silicon-based solar cells with thin-film technologies. This combination leads to increased efficiency. HJT panels consist of a crystalline silicon wafer with amorphous silicon layers on both sides. This design reduces energy losses and improves light collection. These panels offer high efficiency and perform well in various conditions. Additionally, they have an attractive design. As a result, HJT panels have a promising future in solar energy generation and play a crucial role in the transition to renewable energy.

Despite these differences, the common goal of all solar panels is to capture and use the sun's energy to power your home.

How to calculate the size of the solar system for my home?

Monthly Electricity Consumption: Begin by understanding your monthly energy consumption. Look at your Last six-month electricity bills to identify your average monthly or annual...

How much would it cost to install a 3kW solar system? Is government subsidy applicable? If yes, how can you avail it?

Assuming you will be using high-quality solar panels, a 1kW solar system will typically cost between Rs 60000 and Rs 70,000.

How to clean the solar panels?

Solar panels work by harnessing energy from the sun, which means they need to be exposed to as much sunlight as possible to operate effectively. However, factors such as dirt, dust, and debris can cause a reduction in solar panel efficiency...
