Frequently Asked Questions

There are two basic types of technology available in the market: Polycrystalline and Monocrystalline.

Monocrystalline panels come with higher wattage capacity so you can opt for mono panels if there is an unavailability of enough space and want higher efficiency however monocrystalline panels are often a little expensive. On the other hand, Polycrystalline Solar Panels are less expensive and can be used where the space is not a primary concern and have the good availability of solar radiations.

ON Grid Solar System means your Solar Plant is synchronized with the local utility Grid. If you are producing more energy from your Solar System than you are using, the excess energy will be sent to the utility grid and based on the Solar Policy of your state you can build credit that you can cash out with at the end of the month/year, in a process called net metering. In the ON Grid System, you cannot store any energy which you want to use at the time of Grid failure/Power cut.

OFF Grid Solar system means your Solar plant is not connected with the grid. Your power requirement is fulfilled by Solar and You can store the energy in battery banks and can use it at night or when the weather is cloudy or rainy.

ON Grid Solar System cannot provide you any backup at the time of grid failure or power cut.

OFF Grid System requires battery bank which are expensive, bulky, needs regular maintenance and not very environmentally friendly. In OFF Grid System when you are using the battery banks then you won't be able to meet the entire energy requirement for your house hold or office.

Net metering is an arrangement in which you can export the excess electricity into the utility grid and can be adjusted against your consumption. A bidirectional ‘Net Meter’ is used to record both export and import of the electricity. If the exported electricity is higher than the imported electricity, you may be compensated for the excess electricity being fed into the grid depending upon your state net metering policy.

Gross metering is an arrangement in which you will be compensated at a fixed feed-in- tariff for the electricity generated by your Solar plant and exported into the Grid and you will have to pay the electricity distribution company at retail supply tariff for the electricity consumed from the grid. The feed-in-tariff rate is lower compared to retail tariff and will be decided by the concerned State Electricity Regulatory Commission.

It depends on your electricity tariff rates for example your tariff rate is INR 7.5/Unit and you have Installed 1kW Solar ON Grid plant then your Solar plant will generate approximately 120 units/month so your savings would be 120X7.5 = INR 900/month.

Subsidy is available for residential customers and up to 10kW only, it depends upon the Solar policy of the state. You can check the subsidy scheme from your state’s Renewable Energy Agencies website before going to Solar.

Choosing the correct installer is the key milestone for your solar journey and eSunScope helps you the best in this. Once you have decided to move forward with solar installation, eSunScope will prepare an RFP document having detailed specification, scope of work along with applicable standards and invite bids from all the EPCs, who have been verified by eSunScope and are registered on its digital platform. The unique bidding platform of eSunScope helps.customers in identifying the correct installer with competitive price. Once bids are received you will see all the bids received along with eSunScope's recommendations. As a customer, you will have the option to select the EPC you want to proceed with based on price or quality or value for money.

It depends upon the type of Solar Panel Technology, if you choose Monocrystalline Solar Panels then 1kW of Solar PV plant would need around 8sqm of area and if you choose Polycrystalline Solar Panels then 1kW of Solar PV plant would need around 10sqm of area.

It depends on many things viz Solar Panel Technology, type of structure, Inverter make, total plant capacity etc., approximate cost of 1kW Solar ON Grid plant is INR 40000 to 45000.

The ideal direction to install Solar Panels are South and it should be installed at latitude angle of the location to get more generation.

Solar panels require little to no maintenance as there are no moving parts. Solar panels are made up of durable tempered glass and layers of protection as they get exposed to the outer environment. A very little maintenance is required like cleaning the solar panels at least twice a month or immediately if there is some bird droppings to make the things run smoothly and to generate the maximum amount of power. The inverter replacement period is 10-12 years after the installation.

Solar panels come with two types of warranties, product warranty and performance warranty. Product warranty is given by the manufacturers which includes any manufacturing defects, durability issues, quality issues or material and equipment failures. In general, solar panel manufacturers provide 10-12 years product warranty. On the other hand, Performance warranty refers to the power output or base electricity production over the 25 years. Once the solar panels are installed at your site and exposed to the sunlight the solar cell degrades every year to some extent and the output power slightly declines. This must not be greater than 2.5% for the first year and 0.7% /year in 2-25 years.
