Solar FreezersAt Solaristique, we design and deploy affordable solar-powered refrigeration and cooling systems for farmers, food vendors, clinics, households, and businesses operating in both grid and off-grid communities across Africa. Our solutions combine clean energy, recycled cooling technology, and smart IoT systems to reduce food waste, improve cold chain access, and create sustainable economic opportunities.
Our circular manufacturing model transforms discarded refrigerators into solar-ready cold storage units — refurbished and upgraded with energy-efficient DC compressors and solar-compatible cooling systems. Powered by solar panels and supported by battery storage, our products deliver reliable cooling even in areas with little or no electricity, at prices over 35% more affordable than conventional alternatives.
Translating solar energy into cold storage impact
Our commitment to affordable, circular cold storage means that farmers, fishers, traders, clinics, and communities no longer have to choose between losing produce and affording refrigeration. By bridging the gap between solar technology and real-world food preservation needs, we deliver durable, IoT-enabled cold storage solutions that also generate carbon credit income for users.
- Save up to 40% on post-harvest losses with reliable solar cooling
- Available for both grid and off-grid communities across Africa
- 35%+ more affordable than competing products through circular manufacturing
- IoT-enabled smart monitoring with shared carbon credit revenue for users
- Preserves fish, meat, dairy, beverages, vaccines & agricultural produce
Our Cold Storage Product Range
We offer a comprehensive range of solar-powered cold storage and cooling products — each designed for a specific use case, community type, or distribution need. Whether you are a smallholder farmer, a market vendor, a clinic, or a cold-chain logistics operator, we have a solution built for you.
- All products are compatible with solar, battery storage, generator, or grid electricity
- Multi-source compatibility ensures uninterrupted cooling regardless of power availability

Community Cooling Centres
Solar-powered cold storage hubs in off-grid and underserved communities operating on a Pay-As-You-Go (PAYGO) model. Farmers, fishers, traders, and community members preserve produce affordably without owning personal refrigeration. Includes shared cold storage and ice block production powered entirely by solar energy.
Order NowBuilt for Community Impact
Our solar cold storage solutions are designed not just to preserve food, but to transform livelihoods. By decentralising access to cold storage infrastructure, we strengthen local food systems, reduce post-harvest losses, increase farmer and trader incomes, and create new income streams through shared carbon credit revenue.
Reducing Post-Harvest Losses
Farmers and food businesses save up to 40% on post-harvest losses by gaining access to reliable, affordable solar cold storage — directly increasing income and improving food quality for consumers.
Generating Carbon Credit Income
Our IoT systems track food waste reduction and methane emissions avoided through solar-powered refrigeration. This verified data generates tradable carbon credits — with revenue shared directly with product users as an additional income stream.
Strengthening Local Food Systems
Community cooling centres decentralise cold storage access in off-grid areas, enabling more farmers, fishers, and traders to participate in local food supply chains while reducing dependence on expensive, centralised cold chain infrastructure.
Frequently Asked Questions
We offer solar freezers, inverter freezers, solar chill kiosks, solar cooling vans, solar tricycle freezers, and community cooling centres. All products are powered by solar panels with battery storage, and most are compatible with solar, generator, or grid electricity.
We use a circular economy manufacturing model — sourcing and refurbishing discarded refrigerators, then upgrading them with DC compressors and solar-compatible cooling systems. This eliminates most raw material manufacturing costs, passing the savings on to customers while also reducing electronic waste.
Yes. All our solar cold storage systems are specifically designed for off-grid and unreliable-grid environments. Each unit is powered by solar panels and supported by battery storage that provides reliable cooling day and night — even in areas with no grid electricity at all.
Our Community Cooling Centres operate on a Pay-As-You-Go model — farmers, fishers, and traders pay only for the cold storage space or ice they use, without needing to own or maintain personal refrigeration equipment. This makes cold storage accessible to low-income communities that cannot afford large upfront investments.
Our IoT-enabled cooling systems monitor energy usage, food preservation impact, and the carbon and methane emissions avoided. This data is verified and used in carbon credit markets. Revenue from traded carbon credits is then shared between Solaristique and the product user — creating an additional income stream on top of the cost savings from reduced food spoilage.
