Executive Summary
The Problem
Solar PV gives DC Power
But load is AC
Needs a DC-AC convertor
Now if we add a battery
Battery stores only DC
Require a AC-DC convertor for charging
Require a DC-AC convertor during discharging
For low power, each convertor* can have 10 to 15% loss
Solar with battery may have 25 to 45% loss

Solar DC
DC Advantage Basic Home Loads are moving to DC
Electronics devices work on low-voltage DC
TV (LED/LCD), laptops. Cell-phones, speaker-phones, tablets,
speakers
AC to DC conversion has losses from 20% to 50% in each device
Refrigerators, air-conditioners, washing machine moving to BLDC motors
AC fan 72W BLDC fan 30W
at speed 1 60W 9W
CFL tube 36W LED tube 15W
low intensity na 4W
Move to Solar-DC at Premises
48V DC line as an additional power line at home
Highly power-efficient usage of Solar
Low-power from grid alone converted from AC-DC
Designed to have minimal loss
Battery can be added with higher efficiency (no convertors), if required

Why is Decentralized Solar important?
Grid: ₹4 to 9 per kWh:
Diesel generator: ₹24 per unit at 85% load: instantaneous
at 40% generator load, costs goes up to ₹34 per unit
Battery back-up: storage costs ₹12-15 + ₹5 per kWh
Solar PV: under ₹5 per kWh when dc is used: day time only
Conversion to AC may add ₹1.00 per unit; No land-cost added
Solar PV power price at DC level
PV cost per kW 60000 sun-hours per day 5
interest rate % 12% sun-days / year 300
depreciation (yrs) 20 total units gen per year 1700

Go-to-market strategy
o Focus Area – GOA o Targeted at Residential and Commercial consumers.
o Sell as a box (CapEx) or as a solution (Stream)
o Shift gradually more towards streaming model
o Upside – OGH o Position an an alternative to Home Inverter Market
o Productize and sell OGH box.
o Channel Network / Franchisee for deployments & Service
o 100K OGH initiative
o Upside – UDC o 100,000 home UDC project, Proposal stage at MoP
o 8-10 Sub-Station (SS) in a one town.
o Cygni will do SS side work.
o Channel / Network for home deployments
Scaling up challenges
o Math has to work
o Customer has to see / experience value
o Business Timing
o Team skill set
o Ability to execute
o Hard work & Sincerity
