Introduction
In this solution, solar provides free energy during day. Grid is automatically disconnected by the PCU
Extra energy produced during day gets stored in lithium batteries.
When generation is lower than consumption, batteries join solar. Post sunset, batteries take up the load
When batteries drain out – grid is connected as the last option. (configuration can be changed to preserve batteries as backup).
All this happens automatically without intervention
There are installations which are almost grid free
Lithium batteries last 10-20 years, are multiple times smaller, are completely maintenance free – storage technology of future.
Issues with existing solutions
Traditional Battery + Inverter
Traditional Battery + inverter | Solar + Lithium |
This combo cannot last for more than few hours during power cuts | Solar provides cover during day without need of battery. Lithium battery takes up after sunset |
Traditional lead acid batteries needs replacement every 3-5 years (500 cycles) | Lithium has 10 times more life (5000 cycles). Virtually buy of a lifetime |
Lead Acid batteries need water refill every few months | Maintenance free |
Lead Acid batteries emit dangerous fumes | No fumes |
Lead Acid batteries are bulky | 1/5th the size of lead acid battery |
Power bill increases due to additional AC-DC conversion loses | Electricity bill reduces as solar powers the premises – grid is disconnected most of time |
On Grid Solar
On Grid Solar Set | Solar + Lithium |
Unavailable when needed the most – during power cuts | Savior during power cuts |
No commercial sense for user if gross meter is implemented (eventually net meter will replace gross meter – DISCOM cannot sustain net metering. UP, West Bengal, Kerala has replaced Net meter with Gross meter. Maharashtra has already attempted once ) | You consume what you produce – no dependency on grid |
Getting Net Meter needs government approvals | No approvals needed |
Diesel Generator Set
DG Set | Solar + Lithium |
HUGE running cost – unsustainable | Free power from Sun |
Pollutive | Pollution free |
Significant regular maintenance required | No moving parts – install it, forget it.. |
Cost
Disclaimer
Lithium + solar is expensive
Not your solution if you are looking for subsidy or EMI ( go for on grid instead)
Not your solution if saving electricity is your only priority (go for on-grid instead)
This is convenience first solution with electricity savings as second priority
This competes commercially if generator set cost is added
Rate Card
5 kVA à 5,10,000/-
8 kVA à 8,16,000/-
10 kVA à 10,20,000/-
15 kVA à 15,30,000/-
What you get:
End to end implementation – material + installation +transportation
Default configuration will have Solar Panels, Solar Inverter, Lithium Batteries (1.5 hours of backup at 50% load), fixed structure, earthing equipment, lightening arrestors
Out of scope – we will need input to plug in our PCU and hand over AC current for distribution (to your electrician)
Customization possible as per your needs at additional cost
Why Dabun?
Dabun is a Government of India (DPIIT) recognized private limited company specializing in solar sector
Registered with Ministry of Micro, Small and Medium Enterprises (MSME), Government of India
Headquartered at Pune, Maharashtra
Operations across India
Unique Preposition
End-to-End Solar Plant Outsourcing
The only company that takes end-to-end responsibility of the entire solar plant.
Because we are the only company that has its own panels, PCU, batteries, structures and installation service. This enables us to provide end to end coverage of the plant. Traditional installers will “assemble” plant in piece meal manner – warranty resides with manufacturers and coordination responsibility lies with customer.
No more running from pillar-to-post following up with manufacturers of individual component
No more passing-the-buck syndrome post commissioning
Expertise in offgrid/Hybrid solar system
One of the handful of companies in India that has proven expertise in offgrid/hybrid system
Wide range from 5kVA to 350 kVA
Run rate of setting up more than 1 MWT/year of offgrid plants across India
Lithium Storage
One of the first to adopt lithium storage technology in India. Lithium storage compatible PCUs from 5 kVA to 150 kVA.
Suntrack Technology
One of the few companies that offers SunTrack solar mounting structures for improved efficiency (increased generation by up to 45%)
Financing of Industrial solar plants
Financing for Industrial and commercial solar plant in record time of 5 days
Pan India coverage
One of the few companies in India that aims to provide services and products across India
