Now a days people switch his home electricity on solar panel to reduce his electricity bill and can contribute in green energy. But here are some tips and tricks that you should always keep in mind before buying solar panels.
- Temperature Coefficients
- Consumer Reviews
The efficiency of a solar panel means how much electricity the solar panel produces. Normally 1 kilo watt of sunlight falls on a panel of 1 square meter. The solar that take less space will produce more electricity. Mostly, there are 2 types of solar panels available in India —
Mono crystalline Solar Panels: Mono crystalline solar panels are solar panels of latest technology, which works in less sunny and cloudy weather. The mono crystalline panel is black in color. Their efficiency is 18% — 22%.
Poly crystalline Solar Panels: Poly crystalline Solar Panels are seen in larger quantity in India as they cost less than Mono crystalline Panels. Poly crystalline cells are blue and have an efficiency of 15% — 17%.
We can detect the efficiency of the solar panel with the help of clamp meter or multi meter. Voltage and current of the solar panel can easy be measured with the help of clamp meter.
The durability of a solar panel depends on several small things that are used to make a solar panel, including solar cell, aluminum frame, junction box, wire, MC4 connector, technical level, Backseat and Tampered Glass, etc. are used.
Solar cells are very delicate if a little pressure is applied on them, they can break easily. There are no folded solar cells in India, due to which, tempered glass is applied above for their protection.
Tempered glass is much stronger than normal glass.
Secondly, aluminum frame is used for safety. You must have seen that the aluminum utensils used in the houses are very strong and even after many years of work; they do not have any kind of rust. Due to this reason, aluminum is also used inside the solar panel so that it does not get weaken.
The third thing that is used in the solar panel is the junction box — presently both IP68 and IP67 junction boxes are present in the market, in which IP68 is best and waterproof while the other IP67 can be protected from water for a while.
DC wires are used in the solar panel, company always mention in their detail list whether DC wire is of 6mm or 4mm. This wire consists of very small wires, with a forward MC4 connector that is used to connect the wire to the other wire. The MC4 connector prevents short circuits.MC4 connector is very easy to install.
If all these things are present in the solar panel, then we can say that the solar panel will be easily saved from heavy rain, stones and any heavyweight.
Solar Panel Warranty
Solar panel warranty depends on its quality. Nearly all solar companies offer a 25-year warranty, but in solar panels there are two types of warranties — the first solar panel warranty and the second, performance warranty.
| In the solar panel warranty, if there is any problem or malfunction inside the solar panel, then the company will correct it, but in the performance warranty the company promises that the solar power will produce same amount of electricity in the beginning and coming time too. Warranty should always be known when purchasing solar panels as well as by whom the warranty is given.
The temperature coefficient in the solar panel means that the solar power output decreases as the temperature rises or decreases. When a solar panel is made inside the company, it is tested at 25 degrees to see how much electricity it is producing.
However, in summer season, the temperature of the atmosphere varies from 40 to 50 degrees and in this case the temperature of the solar panel reaches 60 to 70 degrees and less electricity is generated by the solar and in cold weather the temperature of the atmosphere is 15 17 degrees and the solar temperature goes up to 10 degrees, which also produces less electricity.
Consumer reviews have become a very strong and powerful identity in Digital India. Before purchasing any new item, the consumer will first go to the reviews given by other consumers of that item and accordingly make an image for that item in his mind. But this thing is wrong to a large extent because companies take wrong advantage of this thing and write a false review on their company’s goods so that whenever a consumer finds them, he will read the date written there and buy it. Along with this, consumers also take reviews as a threat, if the goods are not delivered to them on time by the company, to buy. The excellent option is to go and read the information given completely once in whichever company you are going to buy.
Also you have to check your inverter rating or type weather it’s a normal inverter or a solar inverter so it can connect with solar panel before buying. There are only few premium solar panel companies in the current market, I would really recommend you to check out INDIA’s no.1 mono panel manufacturer Loom Solar which is fully trusted worthy and provide first-rate services to their customers both online and offline.
