Solar energy is the light, and heat radiated from the Sun. On earth, to have the existence of human life, along with, oxygen and water - heat & light become essential and the source of these is the sun. The nuclear fusion reaction happening on the sun has been the reason for the heat & light it has been generating for millions of years.
Sunlight takes about 8 minutes and 20 seconds to reach the earth's surface, the distance is about 149.22 million Kms. The photons emitted from the surface of the sun travel this long distance to reach earth. So, the actual location of the sun that you can see is about 8 mins and 20 seconds earlier.
How is Solar Energy Produced?
The solar PV modules help a generation of solar energy; however, it can’t be used in its raw form as the panels tend to produce the DC – direct current- a flat linear output and a tendency of lots of transmission losses. Also, all household equipment use AC- alternating current, a sinusoidal wave.
In this scenario, the conversion of DC to AC is very important, for which an inverter is needed. Further, based on the need of requirement, we can then add as many components as possible including rooftop solar to generate electricity.

How will the Rooftop Solar Market shape up in 2022?
The solar panels generate DC power during the day whenever adequate solar radiation is available. This DC power is maximized by a MPPT Charge Controller unit. Part of it is directly fed to an AC load though a charge controller (DC to DC converter) and an inverter, while the remaining power is fed through the charge controller to the battery bank and stored. It is withdrawn from the battery bank when required (usually when adequate solar radiation is not available in the day light hours) and fed to the DC-DC converter. The DC-DC converter is in turn connected to an inverter and the resulting AC power is connected to the load. Read more here: https://www.loomsolar.com/blogs/collections/how-do-solar-panels-work

Are bifacial solar panels worth it?
Bifacial solar panels are the latest technology solar panel which generate electricity from both side of panels – front & back side. The solar cell construction of this solar panel is different from polycrystalline and monocrystalline solar panel. They offer many advantages over traditional solar panels. These can be framed or frameless solar panels.
How to Install Solar Panels at Home?
Solar panels should be installed by professional installers. Any mistake in installing solar panel will lead to lesser efficiency and loss in power generation.
A solar panel is used for battery charging and saving electricity bill in homes and offices.A battery is the collection of cells which stores power. All lead acid batteries come in 12V and are rechargeable batteries. Now, the basic concept of battery and solar panel is “12V battery should be charged by 24V solar panel”. But there is some confusion – if we connect the solar panel and batterydirectly, then battery will be damage after full charge. Here, we can use charge controller or inverter.
How many solar panels are needed to run a house?
People are preferring to install a solar system for its low maintenance and low electricity bill. Many standalone houses are now going solar as monthly electricity bills are high. For a 3-4 bhk house running a refrigerator, washing machine, 3-4 light/ bulbs, fans, iron etc. 4 Shark solar panels (22% efficiency level) will be enough. A 2.5 kVA solar system (one inverter and two batteries) is generally enough for such houses.
Maintenance of Solar Panels
Solar panels are low maintenance products; however, it is important to clean solar panels on a regular basis to clear off the dust particles that get accumulated on it. A Cleaner solar panel might generate up to 25% more power. The cost of maintaining solar panels is near to zero (0) or a few hundred rupees a year. Most solar panels have silicon cells laminated and framed which ensures long life and less maintenance. Cleaning and washing solar panels are a must for longevity and retaining efficiency.

In this post, we are going to talk about how one can have a successful solar business. This is specifically for our dealers and partners and others who want to make the most of the growth rate in the solar industry.
#1. How many KW Solar Panels do I need for my home?
The selection of solar panels depends on two factors:
a) In Case of Power Failures - The solar panels require is 3 times of battery Capacity, so for example, you have 2 batteries of 150 Ah in your home, you should install 3* 150 Ah = 450 watts of solar panels.
b) In case of Saving Electricity Bill: Look at your power bills and check how much units you consumed during a month, let's assume, 300 units (kWH) in a month, so solar panels requirement will be
Solar Panel Requirement = Total power consumption in a month (kWH) / 30 days *4 units power generation per kW. So, in this case, it should be 300/30 *4 = 2.5 kW, i.e. 2500 watts.
#2. Does Solar Panel Work During the night, Monsoon?
Solar panels will produce comparatively less energy during monsoon. More sunlight better your solar panel works. Shades, clouds, and monsoon do affect the performance of solar panels. Amount of electricity is directly related to the amount of sunlight that falls on solar panels.
#3. What is the Average Lifespan of a Solar Panel?
Most of the solar panels come with 25 years warranty in India. However, the lifespan of a solar panel can go up to 30 years depending upon brand and quality.
#4. How much 1 kW solar panel power generates and how much space it takes in the installation?
1 kW = 1000 watts, 1 kW solar panel generates on an average 4 kWh in a day depending upon weather conditions, in a sunny day it might generate up to 5 Units, while in winter or cloudy weather, the power generation could be lower up to 3 units a day.
1 kWH = 1 unit = 1000 watt
A solar panel has a standard length of 2 meters and a width of 1meter. Installation of 1 kW solar panel requires 2 solar modules, the space taken by 1 kW solar panels shall be
1000 watts panel will save around ₹1000 per month on average. More the number of panels more electricity you can produce and which will result in more savings. A 1kVa on-grid system can save around ₹1500 per month.
#6. Can the solar panel be installed without Inverter and battery for day uses?
Solar panel is a source of DC electricity, the appliances such as Fan, Television, lights that we use in our home is AC, 230 volts (alternating current) electricity, The DC power could be used directly with solar panels while using AC electricity, It is must use Inverters.
#7. Can I run a ceiling fan directly from solar panels during day time?
Solar generates a direct form of electricity, to use a fan on solar, an inverter is a must, a Fan cannot be used directly from solar panels.
#8. How the efficiency of the solar panel is calculated?
The efficiency of the solar panel is the way to calculate the density of solar module. For example, you have a solar panel that is 1 meter long and 1 meter wide produces 1000 watts, this would be called 100% efficiency of solar panels.
The Formula for calculating solar panel efficiency is
1000 watt / sq. meter is sunlight available at your home
Here is the example to calculate Loom Solar 400 watt solar panel efficiency (400 watts) / (2 meter length) * (1 meter width) * (1000 watt / sq. meter) = 20%
i.e. the efficiency of 400 watt solar panel is 20%.
#9. Where can I buy Solar Panels in India?
There are multiple ways to buy solar panels in India, such as Inverter and solar shops near you and online store such as Loom Solar, Amazon, Flipkart, etc.
#10. How to make a solar panel?
We all know by now, that a solar panel is a device that absorbs sunlight and converts this energy into usable electricity. As the price of a solar panel goes down and efficiencies improve, it is attracting masses all over the world to go off the grid. Once you incur the cost of a solar system and its installation, you can practically generate free electricity over the next 25-30 years. But how is this solar panel made, what materials are involved, how different parts are put together to result in a device that is capable of providing you with free electricity?
