Stand-alone PV systems and their future

Stand alone systems represent more than 80% of the market and are most often used in isolated and less developed areas. They are used for three types of applications: service application, isolated buildings, islands and small communities. The three topics are complementary: technology maturity is the result of service application experience; island systems have to supply main collective needs and economic activities in `solarized areas, PV houses will be the `Pace Setter'. Rural electrification and consumer products appear as the most promising market in the near future. New simple conditions have to be met to start this market for the benefit of remote areas in developed and developing countries. Twenty one suggestions for a 21st solar century are presented, including three kinds of problems: - Financial: save, transfer, lend money, take off the tax, subsidy panels, reduce distribution cost; - Technical: high efficiency appliances, high quality components, long and harmonize life-time, simplify wiring, modularity and simple information. - Human: attractive appliances, installation own, pay, install, maintain by users. An international programme to give a minimum of conveniences to 2 to 3 billion inhabitants is possible with the money saved by replacing all former solutions. The 21 suggestions allowing such as international programme have still to be brought together.
