Renewable energy provides consistent electricity and diversifies fuel sources, boosting energy security and lessening the risk of fuel spills while decreasing the need for imported fuels. Renewable energy also helps to conserve the nation's natural resources. They are urgently required.
As electricity usage and expenses climb, the world looks to renewable energy sources to satisfy its energy needs. Solar energy has been a popular renewable energy source in recent years due to its decreasing costs and increased efficiency. Solar system for home has become popular.
For billions of years, the sun has generated solar energy. The sun's beams (solar radiation) that reach the Earth are referred to as solar energy. This energy can be turned into heat or electricity. Solar energy is simply the capture, storage, and conversion of solar energy to electrical energy. Among the terms to be familiar with are:
Photovoltaics Cells / PV Cells: A solar cell is a device that uses the photovoltaic effect to convert sunlight energy directly into solar electricity.
Photovoltaics Module / PV Module: A photovoltaic module, often known as a PV module, is a bundled linked assembly of photovoltaic cells, also known as solar cells.
What is a Solar System?
A solar system is an arrangement that uses solar energy to create electricity. A typical solar system includes of-
How can we use Solar Energy?
All solar power systemsoperate on the same fundamental principles. Solar panels use the photovoltaic (PV) effect to convert solar energy or sunlight into direct current (DC) power. The DC electricity may either be stored in a battery or transformed into AC power by a solar converter, which can then be utilised to power household appliances. Excess solar energy can be delivered into the power grid for credits or stored in a number of different battery storage devices, depending on the kind of installation. A solar system can be 1 kWh, 2 kWh, 3kW, 5kW, 7.5 kW, or 10kW in size. On average, a house with monthly electricity consumption of 1000 kWh requires 26 – 30 solar panels (Each solar panel is 320 watt).
Solar system price- Installing a solar system for a homeis Rs. 25,000 if you already have a single inverter battery and Rs. 50,000 if you already have a double inverter battery.
Uses of Solar energy
On-grid and off-grid are the two most common types of solar systems. On-grid means that all the components of your system must be connected to the grid. Off-grid means that you have your own power generation system, but it may or may not be connected to the grid. Each has its benefits, but if you want to get into solar it's important that you understand what each system entails so that you can choose which one is right for your home or business.
On grid solar system- An on-grid or grid-tied solar system is one that operates in tandem with the power grid. This implies that any surplus or deficit in electricity may be supplied back into the grid via net metering. Many household users are choosing an On-grid solar system since they may receive credit for the extra power produced by their system and save money on their electricity bills. You will always have access to power, whether from the solar system or the grid. They are not powered by batteries.
Off grid solar system - Off-grid solar systems operate independently of the grid but include batteries that can store the solar power generated and supply electricity after the power goes off or during the night.
Off-grid solar systems must be properly built in order to generate enough electricity throughout the year and have enough battery capacity to satisfy the needs of the residents, even in the dead of winter when there is often significantly less sunshine.
The main differences between off-grid and on-grid solar systems are-
An Auto sense intelligent control smart charger and electronic changeover, hence much better reliability. It conducts the quiet operation of AC motors as well as other inductive loads, unlike the noise that emanates from Modified Sine Wave Systems. It gives more accurate readings and reduced errors. Requires less energy consumption as compared to modified sine wave systems. Is able to run a wide range of appliances including computers/laptops, CFLS and other sensitive electronic devices. It also provides better voltage regulation and less fluctuation, hence a more stable power supply. It is environmentally friendly.
Product name: LKVA Sine Wave Inverter- Can be used for- Power Back-up for Household as well as the computer, Small shops, Small offices etc. Small Water pumps and all motor-based small applications TV Sets, Fans, Tube Lights, computers etc.
Product Name - HKVA Static and UPS inverter- Most appliances like CFL, fans, motor-based equipment like air conditioners and pump sets are designed to work on 50 Hz sine waves. Running such types of equipment on unregulated quasi sine wave-square wave-based inverters poses a risk as regards performance and durability. Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, our inverters and UPS are designed to deliver instantaneous high current during start-up, especially in the case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.
Product Name - Solar hybrid domestic inverter / PCU (MPPT Type) - Lento offers next generation smart MPPT based solar chargers for maximum efficiency and highest performance required in demanding situation. MPPT stands for maximum power point tracking and Lento’s smart MPPT solar chargers play a crucial, central role in stand alone and hybrid solar power installation. MPPT increases energy transfer efficiency by as much as 30% by calculating maximum voltage available from the SPV modules at which maximum power is available for charging and sets the charging current accordingly. Output from SPV modules can vary considerably according to changing weather conditions and incorporation of MPPT means the charging conditions are always optimized by covering extra voltage to amperes and thus speeding up the charging process. Lento uses high grade components to assure best performance and extended life of the unit.
How much solar power do I need to go off the grid?
The average off-grid home usually requires about 7 Kw (or 7000 Watts) of power to rely entirely on its own energy production. Solar panels come in various forms, shapes and sizes.
Can I go completely off-grid with solar panels?
For grid-tied solar panels, grid failure means solar failure, so without more, solar panels can't take you off grid. Even if they could work while the grid were down, you would still have a big problem: since solar panels only generate electricity during the day, you would be left in the dark all night.
Can I Run My Whole House on Solar Energy?
With a modern solar energy system, including power storage, you can definitely run a whole house completely on solar power. Today's high-efficiency solar panels and solar batteries make it cheaper than ever before to power an entire home exclusively using solar energy.
Which is better on grid or off-grid solar?
The biggest downfall of an on-grid system is that it does not provide power during a grid outage. Off-grid systems allow you to store and save your solar power in batteries for use when the power grid goes down. It is meant to be entirely self-sustaining.
What are the advantages of using a grid-connected solar PV system?
The main advantage of a grid-connected PV system is its simplicity, relatively low operating and maintenance costs as well as reduced electricity bills. The disadvantage however is that a sufficient number of solar panels need to be installed to generate the required amount of excess power.
What is a solar house?
A solar house is a house equipped with glass areas and so planned as to utilize the sun's rays extensively in heating.
What is the cost of solar system for House?
On average, the installation of a 1 kW rooftop solar system could cost between Rs 45,000 and Rs 85,000. Batteries would cost extra if power is to be stored. Similarly, the cost for a 5 kW system would fall between Rs 2,25,000 to Rs 3,25,000.
