Gents,

In refs to solar energy usage in Nigeria, it could be done . From the threaded discussion, some are Miss-informed about the cost to have a system installed.An average price for a complete system designed for a 4bedroom house is about ten thousand dollars and about two thousand dollars for installation. It could be roof top mounted or ground mounted depending on the availability of space. the modules  ( inverters ),are the most expensive ranging from 2k to 3k ( Thousand ). I will be glad to help on system design for any one serious about having alternate power in their home in Nigeria. My email address is psor68@yahoo.com. Look out for EM Green Energy,coming soon to Nigeria ( Sept 09) . Maintenance services include in your package.
