Everybody like to refer FAQ – Solar Energy while contemplating to plan installation of Solar Power Plant for their home, shop, business etc. Here are the most sought Frequently Asked Questions – Solar Energy or your can say FAQ – Solar Energy glossary for beginners to advanced researchers of Solar energy
FAQ – Solar Energy
FAQ – Solar Energy 1. How do you convert solar energy into electricity?
Ans : Solar-powered photo-voltaic (PV) Solar panels convert the sunlight into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity generated by the Solar Panels can then be used to supply as new and renewable energy to your home, Institutions, shops, shopping malls, business or any commercial venture including industries.
FAQ – Solar Energy 2. How much does it cost to have solar power?
Ans : Earlier upfront cost for installation of Solar Power Plant was very expensive in India. However presently at the time of this writing, the installation cost of Grid Connected Rooftop Solar Power Plants ranges between INR 60 to 65 per watt: A 5 kW solar system would cost around INR 3,15,000 – INR 3,42,000. Government of India provides 30% MNRE solar subsidy on the benchmark cost. Other than this, many utility companies offer Solar Generation Incentives, Net Metering facilities and PPA arrangements.
FAQ – Solar Energy 3. How long do solar panels last?
Ans : Normally transcribed as Linear Warranty or Performance Warranty; relates to working / performance life in years for solar panels / solar modules. Solar Panels of all brands carry 25 years performance warranty other than product manufacturing warranty. Each solar panel is said to have a much longer lifespan of 25 years, and could last for decades as well.
FAQ – Solar Energy 4. How many solar panels are needed to power a house?
Ans : Rooftop having shadow free area of 550 Square Foot is sufficient to install 5 kW Grid Connected Rooftop Solar Power Plant which would be producing 20-25 units a day as per ideal sun conditions. Depending on the type of panel that you choose, a system of this size would be anywhere from 14-16 solar panels.
FAQ – Solar Energy 5. Do Solar Panels Save Money?
Ans : Despite this fact that you need to invest a lot of money as upfront cost for installation of Grid Connected Rooftop Solar Power Plant System. It is is still recommended to go for Solar, if your electric bill is greater than INR 4-5 Thousand a month. You can start to save money from the very next month, with no money down, by extracting your electricity from solar panels and not the electric company / DISCOM / Grid.
FAQ – Solar Energy 6. How much does a 1 kw solar system cost?
Ans : MNRE, Government of India decides benchmark cost for installation of Grid Connected Rooftop Solar Power Plants. Presently the cost for 2018-19 is fixed as INR 65 per watt for system ranging from 1-5 kilowatt. The average price per watt of a 1 Kw solar system is about INR 70,000, meaning that a 1 kW system would cost around Rupees 65,000 to 70,000 to install.
FAQ 7. Which country uses solar energy the most?
Ans : Though China surpassed USA and Germany as the world’s largest producer of photo-voltaic power in 2015, substantially helped by the fact that the country is also the world’s largest manufacturer of solar panels. India is emerging as the world leader in usage of Solar Energy by competing USA as well as China in the race.
FAQ 8. How long before solar panels pay for themselves?
Ans : The three main reasons which impact the Return of Investment payback period are the cost of the system, the cost of electricity, and the availability of rebates or other monetary incentives. In India, payback times for a 5-kW solar installation range from 4 to 5 years.
FAQ 9. Do solar panels work on a cloudy day?
Ans : This is a biggest Myth: solar panels don’t work when it’s cloudy. Researched answer: Solar panels do perform and generate electricity even in cloudy weather. Though they don’t produce as much electricity as they do on sunny days, but they have been found to produce 25% of its capacity what they produce on a sunny day, or 10% when it’s extremely cloudy.
FAQ 10. Do solar panels need maintenance?
Ans : Solar panels generally require No or very little maintenance since there exists no moving parts in the solar power plant system. Periodically, the panels should be inspected for any dirt or debris that may be accumulated on them. Actually speaking, regular cleaning with plain water may increase the performance of Solar Panels.
FAQ 11 Do solar panels work at night?
Ans : Solar means Sun and vice-versa, Simply take it like this, if sun available, solar panel works, and do not work in absence of sunlight. Electricity required during night could be generated during day time and conserved either in Grid or in Batteries.
Frequently Asked Questions – Solar Energy 12 Can solar power run AC?
Ans : Normally a 1.5 Ton AC consumes 2600 watt surge current once Switched-On. Depending on the tonnage of the AC and heat load in a room, an AC might consume about 1 to 2 units of electricity in an hour. Normally to run all other load of a household smoothly, a 5 kW Grid connected Rooftop Solar is sufficient to take care of your electric bill worries.
FAQ 13 What are disadvantages of solar energy?
Ans : Upfront cost for installation of solar energy system is fairly expensive. It takes up bigger chunk of your rooftop for installation. Storage in batteries is also quite expensive. Pollution and climate conditions may adversely affect the performance of Solar energy Power Plant System.
FAQ 14 What are the advantages of solar energy source?
Ans : Despite being expensive as upfront cost, solar energy is helpful to reduce electric bill up to 90% for next 25 years. Longer Durability of Solar Panels almost 25 years. Zero maintenance except periodical cleaning. Solar energy is an alternative for fossil fuels. It is non-polluting, clean, reliable and renewable source of energy. Risk of damage to the environment is reduced by use of clean green energy.
Frequently Asked Questions – Solar Energy 15 What is a Solar Rooftop System?
Ans : In a solar rooftop system, the solar panels are installed in the roof of any residential, commercial, institutional and industrial buildings. This can be of two types
(i) Hybrid Solar Rooftop System with storage facility using battery, and
(ii) On-Grid Solar Rooftop System i.e. Grid Connected Rooftop Solar System.
FAQ 16 What is Grid Connected Rooftop Solar Power Plant System
Ans : Grid-Tied rooftop solar plants are installed in such areas where grid electricity is available for almost 24 hours a day to enable excess electricity exporting to the Grid through Net Meter.
FAQ 17 Which type of Solar Power Plant are eligible for Solar Subsidy in India
FAQ 18 If batteries are installed in Grid Connected Rooftop Solar Power Plants?
Ans : No batteries are installed in “On-Grid” rooftop Solar Power Plants, however, batteries may be installed in Hybrid solar power plant system.
FAQ 19 If Grid connected Rooftop Solar Power Plants work in absence of Main Grid?
Ans : The ON-GRID solar power plant will not work in the absence of Grid for safety measures. However your load may run on batteries installed in Hybrid solar power plant system.
FAQ 20 What is 25 years warranty of Solar Panels means?
Ans : One Kw on-grid rooftop solar power plant may generate 4 to 5 units per day subject to clear day light and availability of Grid. Solar PV modules may perform at least 25% of its warranted capacity even on cloudy days. Solar PV Modules are warranted to perform 80 to 90% for 25 years i.e 90% for first 10 years and 80% for remaining 15 years.
FAQ 21 How much area is required for installation of 1 kw solar power plant?
Ans : Installation of One kW Solar Power plant would require 110 Square Foot (11 Square metres) shadow free empty roof space.
