FAQ

An On-grid solar power generation system with 5 kW capacity would typically cost between 6000-8000 dollars included( Hybrid inverter -batteries –galvanized iron –PV modules-solar accessories –installation and transportation).

Choose an On-Grid solar power system. These systems are designed to work in conjunction with the grid or simply put your electricity supply. The electricity you generate using this system is fed back to the grid. A net meter is installed along with this system to keep track of the electricity consumed by you versus what you generated and fed back to the grid resulting in savings
that get reflected in the bill. But keep in mind that it does not work when the grid is down, so if power back up is your objective, go for an off-grid solar solution.

Go for Off-grid solar power systems. These systems store the electricity produced by conversion in batteries and utilize the stored energy by converting it back to AC so that you can keep running your appliances during power cuts. It’s a boon if you are living or planning to live in an area with no mains connectivity.

The rising cost of other power sources as well as and
the increasing demand for electricity, especially in a high power cut or no grid areas, has resulted in increased demand for such systems.

The reduction in battery prices over the years has further brought the system cost down. But if you don’t have a power cut issue, then we suggest you go for an on-grid system as it will help you save big on your electricity bill.

A solar panel comprises of multiple PV (photovoltaic) cells that convert sunshine to electricity. Two types of PV Panels are there.

1. Poly Crystalline Solar Panels (A slice cut from a block of silicon, consisting of a large number of crystals. They have a speckled reflective appearance and are very thick. Low cost, generate lesser power, and lesser life span than mono cells).
2. Mono-Crystalline Solar Panels (These cells are much thinner and have a smoother feel to them. High cost, generate higher power and also, it works during low-light and cloudy weather) Loom Solar Technology: Superior quality Mono Crystalline Solar Panels in
the Industry at a very low price.

What is the Efficiency of Solar panels?
The efficiency of a solar panel is calculated by the amount of sunlight it
converts into electricity per unit of area.
Loom Solar Efficiency = 20 %
What is the Temperature Coefficient?
While sunlight is important for the proper functioning of solar panels very
high temperatures can lead to degradation. The temperature coefficient is
measured as the effect of high temperatures on the functioning of solar panels.
The lower the temperature coefficient, the better.

There are broadly two types of rooftop systems that you will hear about -On-Grid solar power systems – These systems are designed to work in conjunction
with the grid or simply put your electricity supply. The electricity you generate
using this system is fed back to the grid.

A net meter is installed along with this system to keep track of the electricity consumed by you versus what you generated and fed back to the grid resulting in savings that get reflected in the bill.

It does not work when the grid is down. Off-grid solar power system – These systems store the electricity produced by conversion in batteries and utilize the stored energy by converting it back to AC as and when required.

The rising cost of other power sources and the increasing demand for electricity, especially in a high power cut or no grid areas, has resulted in increased demand for such systems. The reduction in battery prices over the years has further brought the system cost down.

The most crucial component of a residential solar power plant is an inverter. It acts as an interface that converts power produced by solar panels into electricity which can be consumed to appliances. The type of inverter being used depends on the kind of solar power system you are going for.

Grid-tie solar power systems need high-efficiency power inverters for optimizing their performance. Another kind of high-efficiency solar inverter is there for the off-grid solar power system that can charge batteries both from solar and grid power.

The inbuilt MPPT (Maximum Power Point Tracking) charge controllers in some good quality inverters extract up to 30% more power from solar panels.

It is the most critical part as it acts as the skeleton for the entire system, a sturdy structure will result in years of power generation as it needs to withstand strong winds and other natural forces.

The type and orientation of the structure vary to a great degree depending on multiple factors associated with the location where the solar power system needs to be deployed.

The structure for rooftop solar installation on a flat roof is completely different than that for a slanted roof. The height of your roof is another major factor that determines the composition and alignment of the structure.

The quality of the material used has to be as per the MNRE (ministry of new and renewable energy) specified norms. The structure needs are mostly made of galvanized iron, which is not only stronger than normal iron but rustproof as well making the solar power system last longer.

You can’t use any regular cable for your solar power system.

Specialized cables custom made for residential solar power plants are used to ensure minimal loss of electricity being generated.

They are UV protected and strong and long-lasting enough to withstand the rigors of nature – be it peek of summers, incessant rains or thunderstorms. The use of any ordinary cable is a big health hazard as well with high chances of electrocution for the people in vicinity of the system.

The bad quality wire will not only make you solar power system ineffective but will result in being more expensive as you will end up changing the wires of the entire system in the exposed parts get deteriorated resulting in the risk of electrocution.

If you are going for an off-grid solar solution, solar batteries are one of the crucial components as they allow you to store the electricity generated by the solar plant and use it in case of power outages or in case of no mains.
A good battery would be the one which gives long back up and requires very less maintenance (less frequent water to up).

These are the elements which are essential for the proper functioning and safety of the system.

No compromise must be made on their quality, or it will jeopardize the entire solar power system. In terms of their functioning, while Junction Boxes are used to conceal the wiring connections across the system, Conduits on the other hand are used to protect the wiring of the solar power plants, they can be rigid or flexible or a mix of both based on the requirement.

Lightning Arrestors are deployed to save the entire set up in case of a lightning strike, especially during monsoon while Earthing, which is a grounding system connecting the residential solar power plant to earth is done in order to give passage to excess electricity during the lightning strike and safeguarding the entire system in the process.

The installation of the solar power system needs to be done with precision in order to generate maximum electricity through the solar power plant. No two
rooftops are the same therefore the process requires system design and careful supervision to ensure proper installation of the solar rooftop power plant.

Solar panels used in any solar power system should be installed facing south direction. The tilt angle of solar panel should be around 30% in India, but it varies as per the height of the installation.

Solar panels must be grouted using anchor bolts or concrete foundation to ensure durability in rough conditions.

UPS and batteries must be installed as close to the panels as possible to minimize DC transmission losses. One needs to ensure that the maximum permissible voltage is not exceeded when connecting the panels in the series.
There should be a minimum gap of 5 mm between two solar panels to allow for any expansion in materials.

The solar panels being interconnected must be of the same type (mono or poly) and the same power class. There should be no shade or shadow on the solar panels as this may lead to losses, the formation of hotspots, etc.

The performance of solar (PV) panels are affected by the shading effect of surrounding trees and buildings, passing clouds basically anything that casts a shadow on to the panels. The sunlight converted into energy by the PV panels shall depend on the amount and duration of the shadow falling on it.

Lesser the shadow, more the energy! No shadow – maximum energy!

Solar panels need to face true south direction for maximum power generation.

The reason behind it is that when the sun moves from the east and goes to the west, it leans towards the south direction. Irrespective of which part of the year it is, the inclination will always be towards the south. Hence for the optimum harnessing of sunlight, the solar PV panels should ideally face south.

It is important as many companies might not be around to honor their promise
later.

Sudan is a country where dust tends to accumulate very quickly on the panels hampering their optimum generation. Solar Panels have to be cleaned at least twice every week, would be great if you can manage to do it daily, to make the most of the sun rays falling on it. It is recommended to do it using a wipe after a strong water spray.

If you are going for an off-grid solar solution, solar batteries are one of the crucial components as they allow you to store the electricity generated by the solar plant and use it in case of power outages or in case of no mains.

A good battery would be the one that gives long backup and requires very less maintenance (less frequent water to up). A solar rooftop power system will deliver the full return on investment only if it runs as smoothly as possible. This means periodic inspections of the individual components of the system. Timely intervention can prevent the threat of diminished output or downtime or a safety hazard. This way it’s important to get in touch with a reputed brand to install your solar system so that all this can be taken care of. to visit the same.

It’s suitable for all type of buildings. The only prerogative is that there should be a roof on top of it, strong enough to support the structure. Installation also varies depending on whether the roof is slanted or flat. The position of the surrounding elements, such as buildings or trees, which can cause shade on the panels play a crucial role in determining the area on the roof suitable for optimum solar power generation.

At times there are obstacles on the roof, such as water tanks, which affects how the structure to support the solar panels will be erected as well.

Sure thing! One just needs to make the calculations correctly in terms of what
all appliances are being run on solar. Power requirement of a water pump
generally lies between 250 to 1100 watts.

Just make sure that the total accumulated load does not exceed what is being generated by the solar panels.

It also depends on what type of system do you have. If you have an on-grid
system, you can use the solar power during the day part by directly connecting
the water pump load to the solar set up.

In case of an off-grid system, you can use the energy stored in the batteries to run your water pump any time during the day. The duration of usage will depend on the capacity of the batteries and the level of their charging.

The most crucial part of maintaining a solar power system and making sure of the optimum power generation is to keep the solar panels clean. Ideally, it should be done at least twice a week. If you can do it daily, nothing like it.

Apart from this, all the main components come with performance warranties, so you don’t have to worry about the other stuff too much. Solar panels come with 25 years of performance warranty while that of inverters and batteries keeps on varying.

Ideally, solar power plants are installed to directly convert the sun’s energy into electricity. Batteries help in storing the energy for later use. But, in general, batteries are necessary to keep the system balanced.

Solar trackers are the devices that direct solar panels or modules toward the sun. These devices change the module orientation throughout the day to follow the sun’s path to maximize the energy radiated over them. It has been observed that trackers increase the efficiency of solar panels by 15-20%.

Net Metering is a very important electricity policy for the promotion of distributed energy from renewable energy sources like solar energy.

All consumer establishments connected to the power grid have an electricity meter installed which measures the amount of power consumed during a month in Kilowatt Hours (kWh) which is known as one unit. The power utility compiles the data for power consumption during 1 month and sends a bill which is usually the number of kWh multiplied by the retail electricity rate. A customer can reduce his electricity bills with the help of net metering policy if he has a solar system installed at his establishment. He can send the excess power back to the grid and claim a credit for the same in his monthly electricity bill, with the help of special meters called net meters
