Types of rooftop solar PV systems Rooftop solar PV systems are of 3 types: • Grid-tied – These rooftop systems are primarily designed to supply the generated power to the grid and also power the load. These systems will NOT generate power during a power failure as the inverter shuts down the system to stop sending power into the grid and avoids the risk of electrocuting utility personnel who are working to repair the grid • Grid-interactive – This system works in conjunction with either a battery backup or diesel generator to support the load even during a power failure. • Off-grid – This system does not work with the grid and is designed to work only with a battery backup or diesel generator in off-grid applications The difference between the systems lies in the kind of inverter used, and the inclusion of batteries.
As various vendors use different terminology for these systems we urge you to verify the functions of the offered system rather than going by the name alone. Component Rs.% of total cost PV modules (Crystalline) 52,000 52% Inverters 23,000 23% Balance of System (cables, etc.) 17,000 17% Installation 8,000 8% Total 1,00,000 Note 1: The above prices are for components from Tier 1 manufacturers with 5-year manufacturer’s warranty. In addition the PV modules have output warranty of 90% of rated capacity for the first 10 years and 80% of rated capacity for the next 15 years. Note 2: We have not considered battery backup as that can alter the economics significantly depending on the extent of battery backup (autonomy) required. Not only do batteries add to the initial cost, recurring maintenance, and replacement expenditure, the energy loss on charging and drawing from the battery also adds to the cost of power. A battery backup would add about Rs. 25,000 to the cost of the above system.
Note 3: We have not considered Thin-Film modules as they require more installation area for the same capacity as Crystalline modules and are therefore not preferred for rooftop installations where space is usually a constraint. MNRE Subsidy The Ministry of New and Renewable Energy (MNRE) provides Central Financial Assistance through capital and/or interest subsidy (depending on the nature of the applicant). The summary of the subsidy scheme is provided in the table: S. Category Maximum capacity GOI Support System with battery backup System without battery backup Interest Subsidy 1 Individuals for all applications 1 kWp Rs.51/watt or 30% of project cost whichever is less Rs.30/watt or 30% of project cost whichever is less Soft loans @5% p.a. 2 Individuals for Irrigation, & community drinking water applications 5 kWp Rs.51/watt or 30% of project cost whichever is less Rs.30/watt or 30% of project cost whichever is less Soft loans @5% p.a.
3 Non-commercial/ commercial/industrial applications 100 kWp Rs.51/watt or 30% of project cost whichever is less Rs.30/watt or 30% of project cost whichever is less Soft loans @5% p.a.* 4 Non-commercial/ commercial/industrial mini-grids 250 kWp Rs.90/watt or 30% of project cost whichever is less Soft loans @5% p.a.* *for commercial/ industrial entities either of capital or interest subsidy will be available Note: 1 The benchmark cost for setting up a solar PV plant is Rs. 170/Wp (With battery providing 6 hours of autonomy) and Rs. 100 per Wp (without battery) i.e. If the actual project cost exceeds this amount then project cost will be deemed to be the benchmark cost for calculating the subsidy. Note 2: Benchmark costs are for systems with 5-year warranty for all components (inverters, batteries, switchgear, etc.) other than PV modules which are warranted for 90% of output at end of year 10 and 80% at end of year 25.
PV modules have to be made in India to avail subsidy. Note 3: Capital subsidy is increased to 90% of benchmark cost for special category states (North Eastern states, Sikkim, Jammu & Kashmir, Himachal Pradesh, and Uttarakhand). Prospects for further cost reduction One of the questions we are regularly asked is if project cost is likely to reduce significantly in future, as the price of solar PV modules has seen a substantial decrease in recent years. This chart shows the proportion of the prices of each component (from the table above) to the total project cost: Though PV modules have decreased in price they form only half the cost of the total project; further decrease, if any, will only affect that portion and therefore impact on total project cost will be limited. The prices of the other components have not decreased the way the price of PV modules has decreased. Therefore we do not expect to see much reduction in project cost in the near future. Variations in pricing Prices of solar PV systems offered by various vendors can differ significantly.
