Partnering opportunity

Off-grid solar charging system with stand-alone payment process


UK company providing bespoke technical solutions and consultancy services for sustainable energy generation is seeking collaboration for building an off-grid solar energy charging system with stand-alone “pay as you go” payment process designed for non-electrified areas in developing countries. The collaboration can be based on joint venture or technological cooperation agreement with other technological consultancies or solar systems manufacturers to customize.

Technical Specification or Expertise Sought

The company sees this as an opportunity for a collaborative project with other interested companies that have an expertise in one or more of the following areas below: • Pay-As-You-Go (PAYG) mobile technologies • ICT integrator of the mobile and stand-alone payment solution suit (experience with electricity and airtime payment solutions would be advantageous). • Commercial product developer with experience of solar charging system (with PAYG solution). • Interested renewable energy funders and investors are also welcome.

Partner sought

The company is interested in joint development and technical cooperation with two types of potential partners: • Where technologies that form the building blocks for the system being proposed already exist, such template could be customized to meet this request. • Where a complete solution does not exist, this is an opportunity to develop a new product from scratch with a committed business parties.


The rationale for the proposed technology lays in the ever growing need for affordable sustainably sourced energy in most of the developing countries – a solution that caters for low income earners and smallholders. Over 1 billion people have highly unreliable connections to national electricity grids or are without access to reliable electricity. These consumers turn to costly and unhealthy energy alternatives, such as kerosene and candles for lighting, disposable lead-acid batteries for torches, and diesel to run generators. As an example In Sub-Saharan Africa, 51% of the population lack access to electricity. In Nigeria alone, over 100 million people, or 55% of the population, have no electricity supply mostly living in peri-urban and rural areas. In contrast, mobile networks have become the predominant infrastructure, with over 85% of the population living within mobile coverage. With high mobile coverage and large non-electrified areas in a good number of countries within Sub-Saharan Africa, this UK-based company sees large potential for joint development and roll-out of an affordable and sustainable off-grid solar energy charging solution with stand-alone payment process to help alleviate the above energy related problems for battery storage charging needs. A fully functioning prototype of the proposed system is currently being developed (now at TRL 7 - Operational Prototype (Alpha Product)). The final system would have a Machine-to-Machine connectivity enabling a remote monitoring, control and data collection, with integrated PAYG ("pay-as-you-go") or similar stand-alone mobile payment process. The proposed off-grid solar charging systems would be capable of: • Producing varying wattage output capacities to charge various appliances (such as mobile phones and laptops) • Efficiently storing generated energy • Using Pay-As-You-Go (PAYG) mobile technologies • Using scratch card pin solution as an alternative to PAYG. • Wi-Fi technology – as Wi-Fi hotspot • GSM Module • Wireless processing of system information to a base control system With the prototype development at an advanced stage, the company looks to collaborate on this project and share its benefits via joint venture or technological cooperation agreement with other technology solution providers.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
