The Complete Course on Solar PV Entrepreneurship. The course was very impressive and technically detailed. The experience gained from the programme will enable the participants to render innovative and cost-effective services that will be pivoted to making our clients achieve business sustainability in the 22nd Century, and beyond. Indeed, attending the programme will enable me to contribute towards making Nigeria environmentally-friendly through encouraging clients to use clean Renewable Energy as a means to creatively navigate the power challenge confronting them in their production processes. Overall, it is pertinent to mention that I feel delighted to have attended the programme conducted by the RETTI VIRTUAL UNIVERSITY. Best Regards, Rasaq Adio Adeleye.
