I just did some quick calcs... I've been using solar at some of our remote sites. Romote as in very remote. One such system has 1500+ watt array, 6kw genset, 4000 watt inverter and a big battery bank. Estimated cost was staggering $50 per watt. The solar array alone will pay for the system will be about 20 years in fuel and transportation costs. Even though there's a generator in the system when called upon will run at maximum efficiency thus operation savings will bring that payback cost in around 10 years. These systems are used from beginning may through September. Peak sun months up here
