    Types of solar panels and Inverters You should know about.

    SOLAR PANELS

    Solar panels, also known as photovoltaic cells, are capable of absorbing light energy through semiconductor materials and converting it directly into electricity by the photovoltaic effect. Photo voltaic cells were discovered in the 1960s. Solar panels made up of PV cell modules made it to the rooftop first time in the 1980s. Photo voltaic effects basically ensure that the semiconductor material in the cell absorbs the photons carrying the solar radiation and converts them into electrons. There are different types of solar panels available on market. Initially, these two types were majorly used in the market; mono crystalline and polycrystalline.

    Mono crystalline

    Mono crystalline panels have an efficiency rate of 20%. It is optimized for commercial use. These panels have a high life-time value.

    Poly crystalline

    Polycrystalline panels have a 15% efficiency rate. Although these panels have a lower price compared to monocrystalline solar panels but there are a number of disadvantages; these are sensitive to high temperatures

    These panels have a lower life span and considerably less space efficiency.
    These days, the solar panels which are most frequently used are mono perc panels. From traditional poly panels to mono & bifacial modules, we are continuously evolving.
    Mono-perc is an un-conventional version of mono-crystalline panels that are considered to have higher efficiency even in low-light condition. PERC stands for Passivated Emitter & Rear Cell. It is a modern technology that is designed to increase the efficiency of standard solar modules. This is done by adding a passivated layer in the rear of the cell. In Mono-perc modules, the same passivated layer is added in the back (rear) side of the solar cells. This is designed this way so that any light which is absorbed and passes through the cell is not wasted and used again with help of the rear cells.

    INVERTERS

    Solar Inverter is basically the pivotal unit of whole solar energy unit. It converts the DC energy coming in from solar panels and converts it into AC power to be utilized at home or workplace. The appliances in the house run on AC, not DC, this inverter is required to transform the D output of solar panels to alternating current which helps run all the appliances. Inverters ranging from 10kW-30kW are generally used in households (small residences) and inverters ranging from 20kW up to 100kW are used for commercial uses. Most common inverters used for household and commercial use are Hybrid inverters. Batteries are

    connected with the Hybrid inverters. It engages with the connected batteries through ‘DC coupling’ (when both the solar and batteries use one inverter and the DC from the solar panels charges the batteries via a DC charger) and its electronics organize the charging and discharging of the battery.

     A few major high-end companies of solar inverters are listed below:

    • Sungrow
    • Huawei
    • Solis
    • Growwat
    • Knox

  • What is the mechanism of Net-Metering? How it Work?

    Your solar panels are capable of producing plenty of energy during the day—even when you aren’t home to use it. But the solar panels don’t generate energy at night when you use more power. To overcome this problem we use batteries to store extra energy (Off-grid or Hybrid solar systems). But what if your panels are producing way more power than what your household could use in a day?

    With net metering, you can exchange your excess power for credits from a utility company. Net metering is a mechanism that credits solar energy system owners for the electricity they send to the grid. These credits can be used whenever you need to withdraw power from the grid. In this way, net metering helps you store your excess power, in the form of credits, for any unfortunate time when your solar system is not able to produce enough energy.

    If you’re planning to go Solar, this article will help you understand more about net metering and its advantages.

    THE MECHANISM OF NET-METERING.

    Net metering keeps your solar system connected to the grid so that you can draw or trade power according to your requirement. Secondly, a bidirectional meter is used to measure the energy you produce and utilize. If your solar system is generating excess energy, the two-way meter will run in reverse and send that energy back to the grid. Finally, the utility company will give you credits in return for your excess energy.
    Net metering is a course of action that lets you attain credit for the solar electricity you produce but don’t use right away. If you are aware of how solar energy works and are thinking of switching to solar, the first question that pops up in your mind is how one can keep the house powered up during non-sunny days. This is where the concept of net metering arises. Your solar panels will make ample electricity when the sun is shining at its full power during the day. That electricity is either stored as DC in batteries or converted to AC through an inverter. If your solar system is generating units of electricity more than the units that are being consumed, your electric meter will start running in reverse and send the excess units back to the grid. In exchange, for the extra units that are being exported to the grid, your utility will give you credits on your electricity bill. Also, at night when it’s dark, those units can be consumed and there will never be a blackout at your residence.

    In September 2015, NEPRA issued the regulations that all DISCOs can purchase extra units of electricity produced by the solar systems of customers and adjust them against the units consumed from the grid. After the issuance of these regulations, customers found numerous benefits of the net metering mechanism. Firstly, it reduces your electricity bills drastically. Then you will also save energy since by generating energy through solar panels, you will become more energy independent by relying less on non-renewable resources. Lastly, you are providing power to the community and in short, contributing towards saving power.

  • On-grid, off-grid, hybrid solar

    Difference between Hybrid, on-grid, and off-grid solar systems

    Since Solar systems have gained much popularity over the years, it is essential to know how the system works and what are the major features which differentiate its further types. Photovoltaic effects kick in which means Solar panels will convert solar energy into DC power. This DC power can be stored in a battery or can be converted to AC power by the Solar Inverter. Solar Panels, Solar inverters, and Batteries are the major components of solar systems.


    There are three main types of Solar systems:

    1. On-Grid solar systems
    2. Off-Grid solar systems
    3. Hybrid solar systems

    On-Grid solar systems
    An on-Grid system is commonly named a grid-tied or grid feed solar system. These are the most common solar systems used in business and household units. As the name suggests, these solar systems are publically connected to the electricity grid. Any excess electricity units generated are exported to the grid via net metering. The con of this solar system is that it cannot function in blackouts.

    Off-Grid solar systems

    An off-grid solar system also known as a stand-alone system as the name suggests requires storage (Battery) support. This solar system is designed to cater to the power requirements with enough battery support to be used when there is less or no sunlight as well. These solar systems are a bit expensive as compared to others since batteries are included in them.

    Hybrid solar systems
    Hybrid solar systems as the name suggests is a grid-connected systems along with battery backup. These solar systems can be assembled in various configurations. This solar system stores energy by solar throughout the day and utilizes it at night. It is a solar system dependent upon the grid but can also store extra units in the storage. Hybrid systems are also able to charge the batteries using cheap off-peak electricity. Hybrid systems are much more expensive than off-grid systems. The pros of hybrid systems are that they are secure, cost-effective, and much more efficient than the rest of the systems.
