Understand each solution
What each technology is, what it solves and where it does not fit.
Generation
Generation & Storage
Solar + Battery
Generation with storage so critical equipment keeps running during outages.
- — Frequent power interruptions
- — Diesel generator dependence
Storage
Energy Storage
Standalone battery backup for critical loads.
- — Short but frequent outages
- — Voltage instability
Cold Chain
Cold Chain & Cooling
Solar-assisted cold rooms and chillers that extend shelf life.
- — Post-harvest spoilage
- — Distress selling
Solar Vegetable Storage System
Cooled storage and carts that keep vegetables fresh for longer without grid power.
- — Produce spoils within a day or two of harvest
- — Distress selling at whatever price is offered
Solar Refrigerators
Standalone solar fridges for milk, vaccines, food and small cold retail.
- — Spoilage of milk, food or perishable stock
- — No reliable power for refrigeration
Processing
Solar Drying
Controlled drying for spices, fruit, fish and grain.
- — Slow open-sun drying
- — Contamination and quality rejection
Energy-Efficient Processing
Solar-powered mills, grinders, pulverisers and oil expellers.
- — Manual processing bottlenecks
- — High diesel or grid cost for motors
Mobility
E-Mobility & Retail
Electric carts, solar vending units and charging points.
- — High fuel cost for delivery
- — Limited reach for vendors
Farm Energy
Solar Pumps
Irrigation without diesel.
- — Diesel pumping costs
- — Unreliable daytime supply for irrigation
Enterprise Systems
Textile & Manufacturing
Solar-powered stitching, looms and light manufacturing setups.
- — Production stoppages
- — High per-unit energy cost
Bioenergy
Waste-to-Fuel
Biogas and briquetting from agricultural and food waste.
- — Waste disposal cost
- — Expensive cooking or process heat
Agri Processing
Solar Stone Flour Mill
Solar-powered stone grinding that turns grain into flour without grid power.
- — Grinding depends on unreliable grid power
- — Cost of hauling grain to a distant mill
Solar Dehulling Machine
Solar-driven dehulling that removes husks from grain and pulses on site.
- — Manual dehulling is slow and labour-heavy
- — Value lost by selling unprocessed grain
Solar Sugarcane Juicers
Solar-powered juicing for sugarcane, sold fresh at the point of production.
- — Diesel or grid cost for running the crusher
- — Lost margin on selling cane unprocessed
Retrofit
Solar Conversion Kits
Retrofit kits that convert an existing diesel or electric machine to run on solar.
- — Existing equipment is fine but running cost is high
- — Diesel dependence for daytime operation
Livelihoods
Solar Sewing Machines
Solar-powered stitching units that let tailoring work continue through power cuts.
- — Stitching stops during load shedding
- — Diesel or inverter cost for backup
Solar-powered Silk Reeling
Solar-driven reeling and spinning so silk work is not limited by grid hours.
- — Reeling stops when power fails
- — Poor quality yarn from interrupted reeling
Solar-powered Spinning Machine
Solar spinning equipment for yarn production at household and cluster level.
- — Spinning limited by grid availability
- — Manual spinning is slow and low-yield
