solar panels grid
The solar panels on the roof. Can you help me decide?
If Ed Begley is about perhaps you can help too! 
My house is directly Southwest and need a complete new roof (composition shingles), I would like to put solar panels across the front of the roof. approximately 900 square feet at the front of the house. 1. Do I reroof the panels below the first or I can let the shingles underneat age. 2. Will this be enough to get me out of the grid at the home of my 1800 square meters and outdoor lighting in SAA garden? I have a washer, dryer, refrigerator, dishwasher and oven, and air conditioning run. Thanks for all your help. I have to make this decision before you put the new roof.
Only rough guess here. a solar panel of 115 watts that I have in my house is right at 3 feet wide and 5 meters long. That is 15 square meters. So you get about 7.6 watts per square foot. Times 900 = About 6,900 watt solar on your roof. If you get 5 hours of sun a day peak occurs near 41.4 kWh per day. This is a little more than twice what I use in 1700 Start a square foot. If you need to replace your roof, it could go away and should eliminate all of its solar roof to fix in a few years. So he are replacing the roof why not save some money and install solar roofing shingles. Must be the same or less to be reroof and add solar. And nobody knew solar was unless you told them. http://store.oynot.com/sh17warosh.html
