A good project idea - but you need to work up a more detailed plan.
For example...
where will you source the equipment from? (links would be good)
are the equipment prices assured or are they likely to go up?
what models / brands will you be using?
what will be the warranty on the equipment?
will you be roof mounting the solar panels, or ground mounting?
how will you ensure the equipment is not stolen?
who have you got for the installation?
are they experienced?
how many similar PV installations have they done before?
what warranty do they offer on their work?
how many people will you serve with this solar PV installation?
will you be charging them for usage?
how will you charge for the electricity?
These are a few starting points for further research and development of the project.
In terms of collecting money for the project it would be best to have a separate dedicated account.
If this is a Smile Nigeria project you will need to clearly show who will benefit from the project.
