The main challenge that Brighterlite is addressing is to secure energy access to rural off-grid Pakistan. It is estimated that as many as 50 million people is living without access to electricity in Pakistan today (IFC). Brighterlite Pakistan serves low/medium-income households as well as small businesses (SMEs) in rural, off-grid areas of Pakistan with SHS systems on a Fee for Service and Lease to Own basis. A typical household has 6 members, and uses kerosene, candles, batteries, torches, open fire, low quality solar products and/or diesel generator for lighting and electricity prior to becoming a Brighterlite customer. The typical small business currently served by Brighterlite are small grocery shops/kiosks, butchers, tailors and local tea/small restaurant shops just to mention a few. Brighterlite customers pay a sign-up fee plus a regular (monthly or weekly) subscription fee, all paid via mobile phone. For the most basic subscription, customers pay about US$ 15 (signup) and US$ 5 (monthly). In the event of missing payments, the customer's system will be shut down by the built-in timer, and the customer will only receive a new code (via SMS) to re-open the system after he has settled his account via mobile payment. Partly in contrast to official statistics, Brighterlite's experience from over 2 years of operation and the installation of ~5000 solar home systems in Punjab and Sindh in Pakistan is that mobile coverage is lacking or unstable in substantial parts of Pakistan's off-grid areas. Brighterlite's sales of solar electricity to off-grid households and small businesses system uniquely allows for this situation, as Brighterlite SHS systems is activated by codes sent to customers by SMS after pre-payment. Hence, the location of the SHH system itself is GSM- independent. It is sufficient that there is GSM coverage nearby. Some of our customers make their own mobile payment from their phone. However, the majority of mobile payment users in Pakistan are used to bringing cash to a mobile money retailer. Our retailers' and franchisees' employees therefore acquire their own mobile wallet or become easypaisa retailers (signing up with Telenor after recommendation from us). They collect cash payments from customers in their vicinity or up to 2 hours outside mobile coverage; transfer the collected amounts to Brighterlite's account, and deliver codes back to the customers.
