The total cost involved in solar panel pricing is strongly dependent on a few factors. The cells costs are charged by the kilowatt per hour that they produce. Brands differ a bit in their efficiency, and a few of them can get above 19 percent. Solar panel pricing is flexible, and to calculate a total, a customer must have some information before crunching the numbers. The average rate per hour ranges from 5 to 10 dollars a kilowatt. It typically takes several years to break even on an investment in sun energy, but the cells can save a homeowner thousands of dollars over the life of the devices.
Solar panel pricing also depends largely on the location, type and size of the photovoltaic system. Because the industry is still in its infancy, though, there isn’t a very intuitive way to compute the cost without just shopping around. Not every region of the country receives the same number of peak sunlight hours, and the northeast is especially dark when compared to the south. Western states tend to get more sun than the rest of the country. Solar power equipment fees also vary from area to area, as well as installation costs and any surcharges or extra taxes. State and local governments also offer different packages of rebates and incentives that can drive the overall cost down rather significantly. Any homeowner can get even more back by selling off any excess power generated by the system to the utility company. This isn’t available in all areas, though, so a consumer should check with area businesses before making a decision.
Solar panel pricing can be determined by getting all of these numbers together. It’s recommended that a prospective buyer figure out what the payback period will be with any system he or she is looking at buying. Selling power back to the utility company will significantly roll back the break even date, so factor that in if possible.
A customer should figure out how many cells will be needed to service the household or business efficiently. Determine the number of kilowatt hours a system will put out a day. Then divide the total kilowatt hours per day by the average number of peak sun hours each day (usually around 5 or so). This will output the number of amps the array puts out. Divide this by the total peak amps and round up. This final figure is the number of panels required to power the building. It’s a lot of math, to be sure, but an installer will be happy to help compute everything for their client.
Region, kilowatt hours, energy usage and efficiency all combine to factor in solar panel pricing. Nearly all arrays range from 11 to 19 percent efficiency. The system is usually installed on the roof to optimize space and reduce the likelihood of damage, though some are set up on the lawn. Some may be also configured to track the sun as it travels through the sky. Most homeowners will be surprised, very pleasantly surprised, by the savings one of these solar electric systems can bring to the home.
