| Upon review of many studies, case histories, and industry literature, it is now widely understood that by installing a solar water heater your water heating bills should drop 50% to 80%. While solar water heating systems usually cost more to initially purchase and install than conventional equipment, the solar systems will provide long term benefits. Also because the sun is free, you are protected from future fuel shortages and price hikes. Your overall fossil fuel conservation and cost savings depends on the following: - The amount of hot water you use - Your geographic location and solar resource - Your solar system performance - Available financing and incentives - Your specific cost of conventional fossil fuels ( natural gas, propane, oil, electricity) Application of solar water heating in both new homes and existing home retrofits have proven benefits, and the economics considering new home loans or refinancing can be even more attractive. Including the price of a solar water heater in a new 30 year Mortgage or Home Equity loan usually amounts to about $13 to $20. per month. Federal income tax deductions for loan interest attributable to the solar system reduces that by about $3 to $5. per month. So if your fuel savings are more than $15. per month, THE SOLAR INVESTMENT IS PROFITABLE IMMEDIATELY. On a monthly basis, you’re saving more than you’re paying. |
