Frequently Asked Questions
PV, short for Photovoltaic, derives its name from the process of converting light (‘photo’) directly into electricity (‘voltaic’). Simply put, a Solar PV system is a power station that generates electricity from sunlight. The main components of a Solar PV system are: Solar Panels/Modules: Solar panels consist of a group of small cells made from semiconductor material. When the sun’s light falls on the modules, it excites the electrons, thereby creating direct current (DC). Storage Battery: The best use of solar energy is to consume it while it is being generated. If the requirement is to store this power and consume it in the non-sunny hours, then solar energy can be stored in batteries for later consumption. Solar Inverter: The DC electricity goes into an inverter that converts it into alternating current (AC). We use AC for running our household or office or factory equipment.
If you planning to install a solar plant, below are some things to consider: ▪ What are your energy demands? How do you consume the power? ▪ What is the availability of the shadow-free area on your rooftop or building premises? ▪ What is the buying option you find more commercially viable (CAPEX or RESCO)? ▪ What would be the savings if you go solar?
Most panel manufacturers give warranty of 25 years, however, there have been plants in operations for 40 years as well
The solar installation is not so costly. It just costs ₹70 for the generation of 1 watt power. There is a very minimal difference between the price of Indian solar panels and imported solar panels. If you are looking for subsidy, then you should go for solar panels made in Solar installation companies in India.
A conventional photovoltaic solar modules on a square foot space will generate 12 watts of power. That’s the way you get to know about the area that you need for installing solar panels. Calculate the amount of energy that you will need and go for installing the solar installation on the space that you need.
A grid tied solar module system is designed such that so the interface is safe and reliable with the utility grid. Any excess production of solar energy is directly exported to the grid during the dat. At night or when there is insufficient solar production periods, utility grid will meet the needs of electricity seamlessly.
An off grid solar module system is designed in such a way that they could function independently of the grid that’s electrical. It is mostly accompanied by a generator that is used as a back-up and a battery storage so that they function properly when solar energy is not being produced by the solar module system
Mostly, the solar modules last for 25 years when installed properly and periodically checked. The major part of the grid tied systems is that the inverter which is connected to them will have to get replaced after 10-15 years. Micro inverters can have the warranty of 25 years and can get practical in certain systems. Otherwise, off grid systems are connected to the batteries which will have to get replaced periodically depending on the type of battery.
It is said that from a 3.5 Wp system, you can actually generate over 3000 kilowatt hours per year. This much of energy should be sufficient for heating a home around more than half, almost three quarters, of the whole year. This much of solar energy will be able to save more than a tonne in Carbon Dioxide and reduce the carbon footprints importantly
Solar panels will work in any part of India as long as they are facing the sun. Because that’s what solar panel is related to. Getting energy from sun’s rays and generating energy that can light up the house of the owner who has installed solar panels on the roof their home
The solar installation companies in India you choose to install panels with will procure them for you so that you don’t have to be an expert to handle the small issues of the panels and could handle them with as much ease as you feel. There are number of good solar panel manufacturers and there is a long list if the solar installation companies that can help you in installing solar panels and get benefits from that.
Solar systems which are connected to the electrical grid for the safety of workers who will attempt to fix power outrages are usually required by utility regulations to shut off during blackouts. If you are in a place, where blackouts occur generally, we recommend you to use battery backup or traditional generators.
