FAQs

How do solar photovoltaic (PV) panels work?

Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity.

How much do I have to invest for a Solar PV Rooftop System?

The cost of a Solar power Rooftop Setup depends on many factors such as the connected load, type and quality of the components used in the system, total available roof area etc.

If I invest in a Solar Rooftop , in how much time will I make my money back?

In a Solar Rooftop System, the major investment is its installation cost and has a minimal maintenance cost and no fuel cost. A 5 KW Solar PV System has average pay back period of approximately 3 to 4 years.

Can I choose off grid with solar panels?

An off-grid system is not connected to the electricity grid and therefore requires battery storage. Off-grid solar systems must be designed appropriately so that they will generate enough power throughout the year and have enough battery capacity to meet the home's requirements, even in the depths of winter when there is generally much less sunlight. But it will cost significantly more compare to on grid.

How much time does it take to install a solar PV system?

It takes about 2-4 weeks to install a smaller system and about 4-8 weeks for larger systems. In certain cases, there may be variations to these timelines on account of access to the site.

Will solar panels generate electricity on cloudy days?

Yes, though they produce less electricity. Under a light overcast sky, panels might produce about half as much as under full sun.

How much roof space will I need for a solar array?

A 1 kW panels requires 100 square feet; of rooftop space. We can extend this to different combinations of rooftop plant capacity and panel efficiency for understanding.

How often should solar panels be cleaned?

Cleaning at regular intervals keeps your panels operating optimally always. We at Waaree Experts recommend that panels be cleaned and maintain; once in a months.

445wp mono panel is N-type or P-type?

445 wp mono panel is P-type panel.

How much units bifacial panels generates?

Bifacial panels make the double-sided panels generate 15% to 20% more electricity than the conventional monofacial panels on one-sided solar modules.

What is the difference between mono and mono half cut?

Normal mono full cell panels are made with 60 or 72 cells on the entire panel. A mono half-Cell module doubles the number of cells into 120 or 144 cells per panel. The panel is the same size as a full cell panel but with double the cells.

Which panel is best mono or poly? Why?

Mono crystalline solar cells are more efficient because they are cut from a single source of silicon. Poly crystalline solar cells are blended from multiple silicon sources and are slightly less efficient.

What is the size and thickness of the panel?

Approx size of solar panels is 1*2 meter and thickness of solar panels is 40 mm.

What is the efficiency of solar panels?

Waaree's solar panels provide an energy efficiency rating between 15 and 20 percent, which is the percentage of solar energy that is being converted into useable electricity.

What is net metering?

A billing mechanism offering the utility provider to get credits for the excess solar energy produced by your solar panels is net metering. There is a difference between how much energy the solar power system provides and how much is used for your home. So the excess electricity produced is sent to the power grid, and you get paid for it.

What are the different types of PV system?

There are three main types of solar PV and storage systems: grid-tied, grid/hybrid and off-grid. It all comes down to the customer's current energy supply and what they want to get out of the system, even though they have their pros and cons.

What is Solar PV System & how does it work?

Solar PV System is a power system that is designed to supply usable solar power by means of photovoltaics. It includes an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system.

Is there any subsidy available?

To increase the generation of solar power & installed solar capacity, Ministry of New and Renewable Energy (MNRE), of India is implementing Grid-connected Rooftop Solar Scheme (Phase-II). Under this scheme Ministry is providing 40% subsidy for the first 3 kW and 20% subsidy beyond 3 kW and upto 10 kW.

How much will I really save on my electricity bills every month?

Homeowners can save approximately 600 units of electricity per month that can reduce their electricity bills by around ₹5,500 with the installation of a 5 kW rooftop solar system in their homes.

Will I ever need to replace my solar panels?

The standard life span of solar panels is about 25 to 30 years, if new technologies do come in, it should be fairly easy to "upgrade” your system to fit your electrical needs. Also it is essential for every solar panel systems to be maintained & cleaned every once in a while, to work efficiently & effectively. If not maintained, solar panels might come to a stage of replacing sooner than their standard life.

Are solar panels difficult to maintain?

Solar panels generally require very little maintenance in order to function. The only thing they need is a periodic light cleaning to make sure dirt, leaves, and other garbage doesn’t obstruct the sun's rays from reaching the solar panels.

What if my roof is in poor condition?

What do you provide in rooftop system for residential?

Solar PV rooftop system is basically a small power plant at your rooftop. Solar PV modules form an array and it requires a mounting structure to hold PV modules at the required angle for maximized generation. Along with mounting structure & solar panels, cables & grounding materials are also included in a residential rooftop system.

What is the life and reliability of Solar PV System?

The reliability and lifespan of solar panels is excellent, according to a recent study by NREL. The researchers looked at 54,500 panels installed between 2000 and 2015. They found that each year, a scant 5 out of 10,000 panels failed.

What is the difference between on grid system and off grid system?

On-grid means your solar system is tied to your local utility's GRID. ... Being off-grid means you are not connected in any way to your grid's power system or utility company. This is appealing because you are 100% self-sustaining your energy use.
