Why solar quotes often look cheaper than the real cost
Most solar installers quote only for the equipment and basic installation. Several costs that are actually part of the total investment either get added later as extras or are excluded entirely without being mentioned. The result: homeowners budget Rs 1,20,000 for a 3 kW system and end up spending Rs 1,40,000 to Rs 1,60,000 by completion.
This is not always dishonest practice. Some costs are variable and hard to estimate at the quote stage. But asking the right questions before signing any agreement ensures you are comparing like with like across quotes.
The 8 costs most commonly left out of solar quotes
1
DISCOM net metering application and processing fee
Filing the net metering application with your DISCOM involves paperwork and sometimes a processing fee. Varies by state and DISCOM, Rs 500 to Rs 3,000 in most states.

Net meter security deposit
DISCOM charges a refundable security deposit when installing the bidirectional meter. Typically Rs 1,000 to Rs 5,000 depending on state and system size.

3
Roof waterproofing or civil work
If your roof has waterproofing that needs to be redone around mounting points, or if any civil work is required, this is almost never included in the standard quote.

Earthing rod installation
Proper earthing is required by DISCOM. If your house does not have adequate earthing, a new earthing rod and connection needs to be installed separately. Rs 3,000 to Rs 8,000 typically.

5
Conduit and cable trunking
Some installers quote for basic wiring only. Proper conduit protection for DC cables on the roof is both a DISCOM requirement and a safety necessity. Adding this post-quote adds cost.

Annual Maintenance Contract (AMC)
First-year AMC is sometimes included; subsequent years are often extra. Read the warranty terms carefully to understand what is included in the product warranty vs what requires AMC payment.

Inverter monitoring device or SIM card
Some inverters require a separate monitoring dongle or SIM card for the mobile app to work. This can be Rs 1,500 to Rs 5,000 extra depending on the brand.

Load-bearing structure upgrade
Older roofs or terraces may need structural reinforcement before mounting. This depends on roof condition and is only identifiable after a physical survey.

How to get a quote that includes everything
💡
Ask every installer for an itemised quote listing each component and cost separately. A quote that simply says “3 kW system, fully installed: Rs 1,20,000” tells you nothing about what is and is not included. A properly itemised quote is the only way to compare across installers accurately.

1
Request itemised breakdown before agreeingEquipment, labour, DISCOM liaison, earthing, conduit, monitoring, each line item listed separately with cost.
2
Ask specifically about DISCOM and net metering chargesIs the net metering application filing, DISCOM inspection coordination, and net meter installation follow-up included or extra?
3
Get a site survey done before finalisingA physical roof inspection identifies earthing requirements, structural needs, and cable routing complexity before you commit to a price.
4
Read the warranty terms line by lineDistinguish between panel product warranty, panel performance warranty, inverter warranty, and workmanship warranty. Each has different coverage and duration.
Frequently asked questions
How much extra should I budget beyond the quoted price?
Budget an additional Rs 10,000 to Rs 25,000 above a standard quote for a 3 kW system to cover DISCOM-related costs, earthing, conduit, and any minor civil work. If your roof is older than 15 years or has known structural concerns, add another Rs 10,000 to Rs 20,000 as a contingency for waterproofing or reinforcement.
Is DISCOM registration cost always extra?
Not always. Some established empanelled installers include DISCOM liaison, net metering application filing, and inspection coordination in their standard price. Others charge it separately at Rs 3,000 to Rs 8,000. Always confirm this specifically in writing before signing the installation agreement.
What is an AMC and do I need one?
AMC is an Annual Maintenance Contract covering periodic cleaning, inspection, and minor repairs. It typically costs Rs 3,000 to Rs 8,000 per year for a 3 kW system. It is not mandatory but recommended for homeowners who cannot monitor and clean the system themselves. Check whether the first year is included in the installation price.
Is the net meter deposit refundable?
Yes. The DISCOM net meter security deposit is refundable when you eventually disconnect from the grid or close your solar account. However, in practice this refund takes time and requires a formal request. Treat it as a long-term deposit rather than an immediate refundable amount.
Should I choose the cheapest quote?
Not based on headline price alone. The cheapest quote may exclude several of the items above, use non-ALMM panels, or skip proper earthing and conduit. Always compare on an equal all-inclusive basis using itemised quotes. The right metric is cost per kW of installed, warranted, DISCOM-registered capacity, not total headline price.
