Q1) What is it like to have solar panels installed on your home’s roof? Are the savings worth it? What are some of the drawbacks, and what are some things most people wouldn’t realize unless they had experience with solar panels?
Installing solar panels at roof tops was one of the best decisions taken by me. I have been using it for about 10 years and since then I haven’t paid electricity bill. It has drastically reduced our Kilowatt consumption. The power generated through it sufficient enough to provide electricity in day as well as night. There are no issues of power cut now as earlier their used to be. The expenses have gone down significantly. Not only this we also got substantial subsidy and tax benefits which brought down the cost by 30-40%. Yes, it does require you to have sufficient space at roof and initial investment which is a concern.
Also, quite often I hear about the shortcomings of this product because people buy low quality product. I would always prefer, if you are making the investment, buy the best panels in the market along with other components. I purchased from Statcon Energiaa and the quality and service are up to mark. I am very satisfied with their product and would highly recommend.
Q2) Is it possible to power a household entirely by solar power?
It depends on your location and the size of the system. If you live in a country like India where nine out of twelve months is warm summer season then you can easily depend on solar panel entirely, also you need to have adequate free area on rooftop for setup. I live in New Delhi and my house generates its entire power through solar power systems. Solar panel along with battery and solar inverter will be necessary because you also need to store power for night/ monsoon/ winter season as there will be very less or no sunlight as solar panel will not generate any power in low light conditions.
Do remember to use solar batteries and inverters of good company. I personally use inverters of Statcon Energiaa company and they are extremely good, and also one more recommendation that go for 5KW or 5KVA solar inverter as they have high storage and it will take the load of entire house They have high storage and backup capacity, durability and are cost effective. The service provided by them is very satisfying, so you can go with their product. My Solar power system has helped me in saving thousands of monies on monthly basis.
Q3) Which solar power plant is better – on the grid or off-grid?
It entirely depends on your situation and electric power supply in your locality.
If in your locality there are frequent power cut-offs after every few hours then you should go for off grid solar plant and that will serve your purpose, but say there are rare or no power cut then you should go for on-grid solar plant.
OFF-GRID inverters use battery for power backup to cater to frequent power cuts but ON-GRID does not require it.
If you live in cities with 24×7 power supply, and If you consider economic benefits, Hybrid solar inverter, which are a combination of ON-GRID and OFF GRID are better and economical. As in case of Hybrid you can locally use the power for battery charging and loads and the excess power can be pumped into the grid and on the basis of my prior experience go for 5KW or 5 KVA inverters so that you don’t have to upgrade in future. Even I use solar panels along with hybrid inverters that can work in case of grid failure and they are quite reliable. You can buy STATCON ENERGIAA hybrid solar inverters as I personally use them.
Q4) How do solar inverters work?
Solar inverter is a device that converts direct current to alternating current using solar energy from the sun.
Its working is simple. The sun rays fall on photovoltaic cell which are made of semiconductors. When the sun rays fall the electrons within semiconductor starts to get into motion and produces direct current (DC) which is stored by the cells. But since it is direct current, we cannot use it, this is where solar inverters come into play. The energy is sent to solar inverter which converts direct current to alternating current further which provides electricity in our house. The amount of alternating current and storage depends on quality of inverters. I use Statcon Energiaa solar inverters and they have high storage backup and low maintenance and high durability.
What should I Know about inverters before purchasing it?
Consider Inverters as the door to your house, it should be large enough so that at the very least, the tallest person in your home can pass through without any issue.
Similarly, the sizing of the Solar Inverter should be more than the maximum load that it needs to cater at any given time. In India, the maximum single-phase household has a power capacity of 5kW single phase. Hence it is recommended that single person households take an inverter of 5kVA or 5kW so that this inverter can take the loads of the entire house without needing to upgrade in the future. You can purchase inverters from Statcon Energiaa as I have been using them for many years and their product quality is very good and durable.
Other things to consider are:
Max. Surge Power (To see how much sudden load it can cater to)
Grid Voltage range (To see if it can work in low or high voltage range)
IOT capability (So that you can monitor the performance remotely)
Protections (MCB protection should be present at all input and outputs)
