Is PV Solar Practical?
While this article is about a city in California rather than somewhere in Nicaragua, I found the analysis very useful. (Note that I got to this site following a link about PV solar in Nicaragua which turned out to be no more than a press release.) This article talks about Murrieta contracting for PV solar for the city hall.
Unlike so many articles that conclude that PV solar is good—or bad—by ignoring the facts that might change the conclusion, this one offers the information so you can see how they reached their decision to go with this system. Of additional interest is that the approach is not based on a capital investment by the part of the government. A private company is providing and installing the equipment and then recovering its costs over the life of the power contract.
Commercial Solar Power approached the city a year ago, offering free installation and equipment accompanied by escalating rates over 20 years. Year one, the city will pay .145 cents per kilowatt/hour. The rate will increase 3 percent each year, to .254 cents at the end of the agreement.
