The future of green energy solar panels Solar panels contain solar cells, also known as photovoltaic cells, made of semiconductors (such as silicon) that convert sunlight into electricity. When light hits the cells, the electrons are separated from their atoms and flow through the cell, thus generating electricity. Nowadays, solar cells contained in domestic installations can convert around 20% of the sunlight they receive into electricity, while some commercial systems can reach 40% of the so-called solar efficiency. However, technology is advancing fast and solar efficiency is expected to grow accordingly, while prices drop. 1kw solar panel system- 1 kw solar system is designed to give power supply for 8-10 hours to 3-4 BHK homes in India having severe power cuts and unreliable electricity supply. It generates a power of 5000 watts during the day using sun power. If you are living in a city or at place where electricity is available but power cuts are frequent and long, This Solar system helps you to run all your power equipment directly from sun, It occupies 100 sqft. space in installation. Running load- Up to 1200 watts of power with combination of - 5 Ceiling Fans, 20 Led lights, 2 Television, 1 refrigerator, 1 mixer and Laptop/Mobile Charging 2kw solar system 2kW solar system is best to run your house load. This capacity solar system will generate 8 units averagely per day. It needs 200 sq. feet roof space for solar panel installation. A 2KW solar system can run 1600 watt of your house load. The most
important thing that how is sunny it is where you stay. The price of solar system depends upon the types of solar system. not as popular as larger systems, a 2kW solar system is still a great option for a smaller household. This is particularly true if your home’s empty between 9am and 4pm weekdays, and you don’t have access to a particularly generous feed-in tariff. And with solar rebates currently available, now’s the time to buy. Here are the details you need to know. Power generated- 9 units a day Number of panels-6 Average payback period 4 years Savings on electricity- The amount of money you save from your solar system depends on when (and how much) electricity you use in your home. A 2kW system generates about half the electricity used in an average home and can save you as much as $145 per electricity bill cycle. However, savings of $90 per billing cycle are more likely.
3kw solar system here 3 kW solar system is a powerful solar system that can run everything from solar except 2-ton air conditioners. The system is ideal to light up your homes, independent floors, villas, offices independently using solar power, without depending on the main power grid. To make up a 3kW solar system you need 12 solar panels, assuming that you use 250W panels.Each panel will be about 1.6m x 1m, so you’ll need at least 20m2 of roof space. 4kw solar power systems- 4kW solar panel systems or 4 kilowatts is 4,000 watts of DC direct current power. This could produce an estimated 300 to 750 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South. There are three type of solar systems - on grid and off grid and hybrid. 4kW Solar System is available in all 3 types. Generally, 4kW Solar System range start from Rs. 2,80,000 - upto 4 Lakh including solar panels, solar inverter, solar structure, accessories and batteries in case on Off-Grid and Hybrid Solar Systems.

Generally, 4kW Solar System range start from Rs. 2,80,000 - upto 4 Lakh including solar panels, solar inverter, solar structure, accessories and batteries in case on Off-Grid and Hybrid Solar Systems. 4kW (kilowatt) solar systems typically sell in the US (as at March 2017) for between $2.95 and $3.50 per watt meaning a cost of between $11,800 and $14,000 before the 26% solar tax credit. After the 26% solar tax credit this equates to a range of $8,732 to $10,360. However, the price varies by state and also depending on whether the system is purchased for cash or whether the system is financed. Most solar financing offers have an origination fee of 10-12% and so systems that are financed are usually 10-15% more expensive. 5kw solar power systems A 5kW solar power system is a size that should easily offset a typical Australian home’s electricity usage. If it doesn’t, then you’ve got one serious energy guzzler of a home and should really consider an energy audit before going solar! 5kW solar systems are also the minimum system size you should be considering if you’re looking to add batteries to your system in the future. Here’s what you need to know about 5kW systems, including price information. How many solar panels will you need?
To make up a 5kW solar system, you need 17 solar panels, assuming you use 300W panels – that will actually give you 5.1kW. Each panel will be about 1.6m x 1m, so you’ll need at least 17.2m² of roof space. 5kW solar system will generate approximately 20kWh per day, depending on your location and a variety of other factors. The average home in Australia uses about 16kWh per day. Note that this does not mean installing a 5kW solar power system will automatically give you a $0 electricity bill, as most households use the majority of their electricity at night when the sun isn’t shining – I talk about this in greater detail
Solar inverters solar inverter is one of the most important elements of the solar electric power system. It converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating 240V current (AC). This AC electricity then can be fed into your home to operate your appliances. The electricity that is not used in your home is then either fed into the grid (electrical power lines) or into home battery storage. New hybrid inverters include an integrated battery management system. Long lasting solar power systems require a high quality inverter with a robust convection cooling system. Low quality inverters have unfortunately failed in the Australian climate. In any solar system, inverter plays an essential role like a brain. The main function of this is to alter DC power to AC power which is generated from the solar array. It allows for monitoring the system so this system operators can observe how this system is working. If you are considering a solar panel system for your home, one of the key decisions you make is the type of inverter to install. Inverters convert direct current (DC) energy which is generated from the solar panels into usable . After the panels themselves, inverters are the most important equipment in the solar power system. The inverter gives analytical information to assist in identifying operations & maintenance to fix issues of the system. This article discusses an overview of a solar system. Definition: A solar inverter can be defined as an electrical converter that changes the uneven DC (direct current) output of a solar panel into an AC (alternating current). This current can be used for different applications like in a viable electrical grid otherwise off-grid electrical network. In a PV system, it is a dangerous BOS (balance of system) component that allows the utilization of normal AC powered apparatus. These inverters have some functions with PV arrays like tracking of utmost PowerPoint & protection of anti-islanding. If we are using a solar system for a home, the selection & installation of the inverter is important. So, an inverter is an essential device
The working principle of the inverter is to use the power from a DC Source such as the solar panel and convert it into AC power. The generated power range will be from 250 V to 600 V. This conversion process can be done with the help of a set of IGBTs (Insulated Gate Bipolar Transistors). When these solid-state devices are connected in the form of H-Bridge, then it oscillates from the DC power to AC power. Working- String Inverter This kind of solar panel is arranged in the form of a string and many strings are allied to a single string inverter. Every string holds the DC power where it is altered into AC power used like electricity. Based on the installation size, you may have many string
inverters where each string gets DC power from some strings. These inverters are good for installations where the panels are arranged on a single plane to avoid facing in different directions. String inverters can also be used with power optimizers as they are module-level power electronics that are mounted at the module level, consequently, every solar panel has one. Manufacturers of the solar panels use power optimizers with their devices & sell as one solution called a smart module so that installation can be made easier. Power optimizers give many benefits like microinverters, but they are less expensive. So it can be a good choice among using inverters like strictly string otherwise micro inverters. Central Inverters These are related to string inverters however they are larger & support additional strings of solar panels. Rather than running strings openly to the inverter, the strings are allied together in a general combiner box so that the DC power runs toward the middle inverter wherever it is transformed to AC power. These inverters needless connections of components, however, they need a pad as well as combiner box as they are suitable for huge installations through reliable production across the array. The range of these inverters is from MWs to the hundreds of KWs and they handle up to 500kW for each area. These are not used in homes but used generally for huge commercial installations & utility-scale solar farms.
