A
- AC and DC charging
Home chargers are AC and slower; public fast chargers are DC and cost about three times as much per unit.
- Accelerated depreciation
A tax write-off of 40% of a solar system's cost in the first year, which shortens payback for businesses that own it.
B
- Banking
Storing surplus daytime solar in the grid and drawing it back later, for a fee.
C
- Cross-subsidy surcharge and additional surcharge
The two biggest fees on open access solar, charged by your DISCOM for the revenue it loses when you switch.
D
- DCR panels and ALMM
The two panel checks that decide whether a home rooftop system qualifies for the PM Surya Ghar subsidy.
- DISCOM and SERC
Your electricity distribution company, and the state commission that sets its tariffs and the grid fees you pay.
G
- Group captive
Co-owning at least 26% of a solar plant and using at least 51% of its power, which removes two big grid fees.
L
- Landed cost
What one unit of solar power really costs once it reaches your meter, after every grid fee.
N
- Net metering
A two-way meter that credits the solar units you send to the grid against the units you take from it.
O
- Open access
Buying electricity from a solar or wind plant of your choice and receiving it through the grid.
R
- RESCO (OPEX) vs CAPEX
Two ways to get rooftop solar: pay per unit with nothing upfront, or buy the system and own it.
T
- Third-party PPA
A long-term contract to buy solar power from a developer, with no investment of your own.
W
- Wheeling and transmission charges
The fees for carrying solar power over the grid to you, plus the small scheduling charges that come with them.
