The sun is abundant in Ghana. If the atmosphere is cloudy still light rays can be tapped. During installation , days of autonomy are factored in to size the battery to prevent inconveniences during rain season. Though the initial capital is expensive but at long run , it is cost effective. Within 6-7 years of installation, you start earning profit from the installation and if you produce more than what you need, you can connect it to the national grid and earn money from it. Solar is renewable, green and it does not pollute the atmosphere. Thanks for sharing this vital information. I look forward to see more from you
