To estimate how much solar panels will reduce energy costs in Sun City, AZ, the following information should be considered:
* ANNUAL AVERAGE DAILY RADIATION APPROXIMATION FOR SUN CITY, AZ IS 5.6 KWH/M^2/DAY
* AVERAGE MONTHLY UTILITY BILL IN SUN CITY, AZ IS $247.16
WHAT HAPPENS TO THE SOLAR RADIATION THAT ISN’T ABSORBED BY A PV SYSTEM?
A PV or photovoltaic system absorbs light from the sun and converts it into electricity via semiconductors. Once this process has been completed there are two possibilities for where all of the remaining energy will end up: heat from non-absorbed photons causes direct thermal losses while some excess photons are converted to heat via fluorescence
* COOLING-SYSTEM AUXILIARY LOAD IN SUN CITY, AZ IS 0%
HOW MUCH ENERGY WILL THE SYSTEM GENERATE ANNUALLY? HOW MUCH ELECTRICITY CAN IT SUPPLY?
After considering all of the previous factors and information, we can estimate that a PV system in Sun City, AZ will reduce annual energy costs by $246/year while supplying 1,505 kWh/year. This means 2.24 tons of CO2 emissions will be offset, equivalent to 261 trees planted or 1.4 acres conserved. An average 5 kW installation should prevent 66 pounds of coal from being burned. The environmental impact should continue to grow as the system produces more energy over its lifetime.
HOW MUCH DOES IT COST TO INSTALL SOLAR PANELS IN SUN CITY, AZ?
The average cost to install a 5-kW system in Sun City, AZ is $7,000. This means the system will probably take 7 years to pay for itself and save you money. At this rate of savings, a homeowner would reduce energy costs by an additional $934 over the following 27 years. The environmental value should be easily calculable from previous factors.
In total, it could be estimated that homeowners in Sun City, AZ can reduce their annual bills by more than half while offsetting 2.24 tons of CO2 emissions per year, equivalent to 261 trees planted or 1.4 acres conserved. At a 5-kW installation, it is estimated that 66 pounds of coal will be prevented from being burned while an average of 1.24 tons of CO2 equivalent [11] will not be released into the atmosphere annually.
Expanding on the environmental value, 5 kW of energy production will reduce the country’s dependence on foreign resources by an estimated 2.5 barrels of oil annually while conserving 437 gallons of water each year. This means solar panels reduce CO2 emissions by an average of 76 pounds per barrel of oil equivalent (CO2e), which is more than most other renewable energy alternatives through the utilization of natural resources for electricity generation.
If you’re looking into ways to reduce your monthly bills and offset greenhouse gas emissions then installing a 5-kW solar panel system in Sun City, AZ is the way to go. It can reduce energy costs up to $246/year, support 261 trees or 1.4 acres of land, reduce CO2 emissions by up to 2.24 tons annually and overall reduce environmental impact by more than any other renewable energy alternative.
