Solavei was launched in September this year. Since then it has attracted over 100,000 members nationwide who take advantage of its $49 plan. Members can also take earn recurring monthly income by sharing with friends and family.

Solavei has an interesting method for spreading its service. Rather than spending a lot money on advertising and brand awareness, the company prefers to ask members to share their service and in turn offers them compensation for their efforts.

Members can bring on new customers through social media or word of mouth. In the first two months of business, Solavei managed to pay out more than $2 million in member commissions. So it seems that the system appeals to its users.

With the added spectrum for iPhones and other smartphones, it could mean that the Solavei is onto something. Social media can spread a good deal like wildfire and so with more on offer, happy customers could see it becoming a preferred provider.
