Solar Panels work on the phenomenon called the Photoelectric Effect to produce electricity. Solar Panels are nothing but blocks of specially designed semiconducting material which produce a small amount of electricity when light falls on them. This small amount of electricity is produced in a large number of solar panels (Solar Arrays) to produce electricity for everyday consumption.

Though the capital cost of a PV System is higher than a DG System, a DG System accounts for a high fuel cost and maintenance cost. While a PV System doesn’t require any fuel and its maintenance is very minimal and easy. Apart from this a Solar PVV System is clean and environmental friendly option for a backup system.

A Solar PV System requires very minimal maintenance from the owner and is very easy to maintain. Regular cleaning of the Solar Arrays should be ensured so that the system works at its full efficiency and occasional checks should be done to ensure that there is no shading over the Solar Array because of any obstruction. The components of the system except the Solar Arrays have to be kept in a shaded area. These small steps can result in a healthier and longer life span of your Solar PV System.

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 4 to 5 years. With the life span of a PV System as high as 20 to 25 years 70 to 75% power produced by it may be considered as the free electricity.

Solar PV is a highly proven and reliable technology and have been in use since 1950s. A PV system that is designed, installed, and maintained well will operate for 25 years or even more than 25 years. The Inverters, which are an integral part of a Solar PV system, may need a replacement once in the 25 years lifetime of the system. Moreover, since there are no moving parts (unless you are using tracking devices to move modules tilt with the movement of the Sun), there is practically negligible wear and tear.

The easiest way to find out how much you pay for electricity (and how much electricity you use per month) is to take a look at your utility electricity bill. Review EnergySage’s guide to reading your electricity bill to find out exactly what to look for.

Net metering is the system that utilities use to credit solar energy system owners for the electricity produced by their solar panels. With net metering, you only pay for the electricity that you use beyond what your solar panels can generate. Net metering policies differ from state to state – from Massachusetts to California – so make sure to do your homework ahead of time.

When you install solar panels on your property, you will still be connected to the grid. This allows you to draw from the grid when your system is not producing all of the power that you need, and send power back to the grid when you produce more than you use. It is possible to go off the grid with a solar energy system that includes battery storage, but it will cost significantly more and is unnecessary for the majority of homeowners.

The conditions for Solar DG Sync arise when load drops to less than Power Produced by Solar Power Plant [e.g. on Saturday, Sundays and other holidays]. This could also happen during a normal day when load is less than power produced by a solar power plant [ like during lunch time or during shift change or immediately after a power source change over]. Or a sudden load trip. Which results in DG Malfunctioning.

On-Grid systems also known as a grid-tied system. It is one that works with local utility’s companies through reference Power. On the other hand, an off-grid system is a system that is totally independent of the national electric grid with a battery bank. Hybrid systems are systems that have two generation sources e.g a solar powered system with storage and a generator. It combines the best approaches of both on-grid and off-grid systems. It could be connected to the national electric grid too and sell the power to the Electric Grid.

Yes, Many banks provide loans for the solar system. Now you can include the solar system in the house loan also.
