I have two weather bugs on my desktop, one of St Louis weather and one of Merida weather. Recently the temperature and humidity has been neck and neck. The last couple of days St Louis has pulled ahead! Of course we have central air and air conditioning in the car It won't be so in Merida. But I have been talking up getting solar system so that we do not have the budget busting electric bills. So when we go to Merida in December we will be talking to whatever experts we can find. I may just have my brother-in-laws father visit us as he has installed it in his house in Puerto Rico and gone from a 750.00 dollar a month electric bill to receiving a check from selling power each month. Santiago Sr is an retired engineer and does major research before he buys anything. I know he would be a great resource for us. Now I know that CFE will not buy my excess power, but it sure would be great to have a zero bill! And you never know, perhaps that could change.... So if anyone out there has some experience with solar in Merida or the Yucatan I would love to hear about it!
