Solar Power Calculations

thermal conversion. KW KW-hour?
So I did some calculations based on the figures I found online. My dad wants to replace your gas heating with electric, solar-powered ….. I said a bad idea, but I tried to estimate the cost …. I do not know if I do well. Then uses 380 million cubic feet per month of natural gas becomes i 3800 CCF / month (100 cubic feet …. CCF MCF 1000 cubic feet) a framework for cooperation natural gas is about 1 1 29305.5 therm therm watt-hours divided by 30 to find a day and get 3.7 * 10 ^ 6 W-HR (3800 RTC * 29305.5 / 30) According to conservative estimates of the solar panels are up to five hours of sun … 3.7 * 10 ^ 6 Wh / 5 h = 7.4 * 10 ^ 5 watts * ******** Not that if *********** properly made $ 4.82 / watt * 7.4 * 10 ^ 5 = W $ 3,600,000 Thanks.
You dropped something. I do not understand the lack of MCF, CCF, etc. But one therm = 30kwhr Let me assume that uses 100 therms a month, you can change required. 100 therms 3000kwhr = Approximately $ 0.10/kwhr now is $ 300 per month cost of electricity, the electric company. Translate 3000kwhr kw, we must divide by the number of hours in a month, 720. To 4.1kw solar panels seem to run about $ 4 per watt, not including installation, electronics, etc. I double for other expenses. Therefore, $ 8 / W if you try to calculate the investment capital to generate an 4.1kw calculating Gross, 4100 watts multiplied by $ 8, $ 32,000. But the sun does not shine 24 hours a day. In winter, only 5:00, we must multiply by 5 or $ 160,000. But that does not include batteries and power converters when the sun does not shine, and could double or triple the cost. Hope this helps.
