Homeowners who install photovoltaic power systems receive numerous benefits: lower electric bills, lower carbon footprints, and potentially higher home values. But these benefits typically come with significant installation and maintenance costs, and the magnitude of the gains can vary widely from one house to another.

This article will help homeowners make the financial calculations required to determine the viability of solar power in their homes. Photovoltaic PV solar technology has been around since the s, but, thanks to declining solar module prices, it has only been considered a financially viable technology for widespread use since the turn of the millennium.

Solar panel size is quoted in terms of the theoretical electrical output potential in watts. But this calculation may be misleading because there is little reason to speak of "typical" results; in fact, solar may make sense for one household, but not for the house next door. This discrepancy can be attributed to the financial and practical considerations considered in determining viability.

Solar power is capital intensive , and the main cost of owning a system comes upfront when buying the equipment. The solar module will almost certainly represent the largest single component of the overall expense.

Other equipment necessary for installation includes an inverter to turn the direct current produced by the panel into the alternating current used by household appliances , metering equipment if it is necessary to see how much power is produced , and various housing components along with cables and wiring gear. Some homeowners also consider battery storage. Historically, batteries have been prohibitively expensive and unnecessary if the utility pays for excess electricity that is fed into the grid see below.

The installation labor cost must also be factored in. In addition to installation costs, there are some further costs associated with operating and maintaining a PV solar array. Aside from cleaning the panels regularly, inverters and batteries if installed generally need replacement after several years of use. Government incentives change often, but historically, the U. More details on incentive programs in the U. In other countries, such information is often available on government or solar advocacy websites.

Homeowners should also check with their local utility company to see whether it offers financial incentives for solar installation, and to determine what its policy is for grid interconnection and for selling excess power into the grid. The U. A significant benefit to PV installation is a lower energy bill, but the magnitude of this benefit depends on the amount of solar energy that can be produced given the available conditions and the way in which utilities charge for electricity.

The first consideration is the solar irradiation levels available in the home's geographical location. When it comes to using solar panels, being closer to the equator is generally better, but other factors must be considered. Similar maps and data are available in other countries as well, often from government environmental agencies or renewable energy organizations.

Equally important is the home's orientation; for rooftop arrays, a south-facing roof without trees or other objects obstructing sunlight maximizes the available solar energy. If this is not available, panels can be mounted on external supports and installed away from the house, incurring additional costs for the extra hardware and cables.

The second consideration is the timing of solar power production, and how utilities charge for electricity. Solar power generation occurs primarily during the afternoon and is higher during summer, thus corresponding relatively well to overall electricity demand in warm climates because it is at these times that air conditioners consume the most energy. Consequently, solar power is valuable because the alternative methods of energy production often natural gas power plants used to meet peak energy demand tend to be expensive.

But utilities often charge residential consumers a flat rate for electricity, regardless of the time of consumption. This means that instead of offsetting the expensive cost of peak electricity production, homeowners' solar power systems merely offset the price they are charged for electricity, which is much closer to the average cost of power production.

However, many utility companies in the U. A PV solar array may be very beneficial in areas where this sort of time-varying rate is used since the solar power produced would offset the most costly electricity. Exactly how beneficial this is for a given homeowner depends on the exact timing and magnitude of the rate changes under such a plan. Similarly, utilities in some locations have pricing schemes that vary over different times of the year due to regular seasonal demand fluctuations.

Those with higher rates during the summer make solar power more valuable. Some utilities have tiered pricing plans in which the marginal price of electricity changes as consumption rises. On top of that, there are environmental benefits of renewable energy and, if you add batteries to your solar installation, the peace of mind that comes with being more resilient if the power goes out.

On this page: Defining the payback period for solar panels Current average solar panel payback period What is a good solar payback period? How is the payback period defined for solar panels? Average solar panel payback period for homes in the US in Most homeowners in the United States can expect their solar panels to pay for themselves in between 9 and 12 years, depending on the state they live in.

Key takeaways Solar panels pay for themselves over time by saving you money on electricity bills, and in some cases, earning you money through ongoing incentive payments.

Solar panel payback time averages between 5 and 15 years in the United States, depending where you live. How quickly your solar panels pay back their cost depends on how much you paid, the price of electricity from your utility, and available upfront and ongoing incentives.

Solar batteries. Catherine Lane November 3, Solar financing. Ana Almerini October 29, How do solar panels create solar energy? In addition to the widespread promotion of the benefits of solar power, the rising cost of domestic energy encourages more homeowners to wonder if solar is a worthwhile investment. This depends largely on the answer to the question: how long does it take me to pay off my solar panels?

There are several factors influencing the answer, including the size of your house, how much power you use, and even where you live. You are contemplating a massive installation on your roof, which will totally change the appearance of your house, and could even put off potential buyers if you need to sell.

This is, though, before the Federal tax credits of 30 percent, plus the rebates that your state will receive. For instance, an average household would probably need a system of 5 kilowatts 5, watts. The other factor determining your pay-off time is the regular electricity rate in your region. Generally, the less expensive your system, and the higher your regular electricity rate, the shorter the pay-back time on your system will be.
