How Much Do Residential Solar Panels Cost For An Average 2000 Square Foot Home
Solar panel cost is often measured as the cost per watt of solar. This makes it easy to compare the relative value of solar systems of different sizes in terms of the watts of power they can produce.
Our data shows that the average cost of a residential solar system in 2021 is $2.85 per watt, before the federal tax credit. At that price, a typical 7 kilowatt home solar system would cost $19,950. The cost would fall to $14,763 after claiming the 26% solar tax credit.
The cost of residential solar panels has dropped dramatically over time. In fact, it has fallen over 70% in the past decade.
In 2019 alone, the cost of solar dropped by 5%.
Pros And Cons Of Solar Panels In The Uk
There are many advantages of solar panels, and they play a significant role in the progress towards sustainability. In 2018, the UK generated 3.9% of its total electricity using solar power, and there are currently more than 1 million solar PV installations. The UKs solar capacity is only going to increase over the years.
Besides being environmentally friendly, solar cells provide significant savings on your electricity bill. While there are disadvantages to solar panels, the long-term benefits of investing in solar far outweigh the cons.
There has been a slight increase in sunshine hours over the years, meaning you can get more and more out of your solar panel investment. The graph below shows the gradual increase in sunshine hours in the UK.
Solar panels can be a great way to cover your household electricity needs free of charge, however, there are downsides to solar panels that must also be considered. Below is a list of the main advantages and disadvantages of this renewable source of energy.
They Depend On The Weather In Terms Of Energy Production
This is one of the biggest cons of solar panels. We all know that the entire concept of solar energy depends upon the energy of the sun. The solar panels convert the solar energy into energy that you can use at your own home.
However, what happens when it is cloudy or rainy? It can be worse if you are living in an area that naturally has harsh weather .
While the clouds dont actually hinder the process of energy production, it can slow it down considerably. This naturally means that you already have a limited time to collect solar energy as it cannot be done at night. Follow our guide to understand how solar panels perform in weather conditions.
Out of the remaining time, if it starts to rain or gets cloudy, it can really affect the productivity of your solar panels. That is why we recommend weighing your options in case you are colder regions.

How A 100% Green Electricity Plan Is A Great Alternative To Solar Panels
With its perpetually sunny climate, Texas ranks in the top 10 U.S. states in its cumulative solar capacity. As a result, the Texas solar industry has grown rapidly in terms of electricity generation and the number of people it employs. With it, household enthusiasm for solar panels has also increased. However, the two main concerns people have when it comes to solar panel installation are production capacity and costs.
Solar panels in residential settings currently face limitations since most homes have no way of storing extra solar power on sunny days when solar panels create more electricity than the home can use. Thankfully, further technological progress will likely address this storage problem, as it plagues the entire industry.
In regard to costs, regular electricity companies can offer lower rates on traditional electricity plans than those powered by solar energy because of an economic concept called economies to scale. In essence, the costs for each additional unit of output decrease as more output is created. In other words, because more households are connected to the Texas electricity grid than use solar panels, the average cost of electricity is lower for each household than it would be with individual solar panels.

What Percentage Of Your Home Can You Power With Solar Electricity
Ideally, the answer to this question would be 100 percent. However, although a solar panel system can theoretically offset all of your energy use, its not realistic to expect that level of panel production every day of the week. Manufacturers and installers often recommend that homeowners factor in a 25 percent cushion when calculating their target for solar panel offset. The main reason for this: solar panels cannot operate at maximum efficiency all the time. There will be certain days when grid connection is necessary to fully cover your power usage. However, the beauty of net-metering is that you can benefit from surplus production days and never pay anything to your utility while still relying on the grid for backup storage.

Do Your Research On The Practicality Of Going Solar In Bc
Solar energy is an affordable alternative energy that can be used to help heat and power your home or business. However, there are some important considerations around the use of both solar photovoltaic and solar thermal systems in British Columbia that you should be aware of.
While the cost of installing a solar photovoltaic system for electricity generation has dropped dramatically in recent years, for homeowners in B.C. connected to the BC Hydro electrical system, it would take at least 20 years to recoup the investment at today’s average electricity rates. However, in remote locations where there is no grid to tie into for power, off-grid solar PV systems can be used to store power in batteries and can make for a sound investment.
In Canada, solar thermal systems are used mostly for domestic water heating rather than for primary space heating. In our climate conditions, other fuel-source options may be more economical for primary space heating than a solar thermal system.
So Is Solar Really Worth It
When installations are assessed, designed and performed properly, solar energy is one of the best investments you can make. Solar panels are worth it for the majority of customers in the country, but there are certainly some disqualifiers, as described above.
Given the current price of solar energy and an expiring solar tax credit, we predict 2022 will be one of the best times to go solar. Those waiting for prices to drop further may be disappointed when either the tax credit expires or solar prices stabilize due to booming demand.

The Economics Arent Right For You
There are several factors, some of them discussed above, that can negatively affect the economics of solar. If these factors apply to you, you could find that you stand to save little to no money by going solar.
Here are the factors that adversely affect your financial return from installing solar panels:
- High upfront costs for your solar energy system. This is usually because solar equipment and/or installation costs are expensive where you live.
- Space restrictions mean that you cant install a solar panel system large enough to deliver adequate electric bill savings.
- Roof issues such as shading or non-ideal direction or angle negatively affect your homes solar potential.
- Low energy costs – you dont spend much on electricity to begin with.
- Unfavorable financing: Your solar loan comes with a high interest rate or onerous conditions .
- Lack of incentives: Youre not eligible for solar incentives that can substantially reduce system costs, such as the solar tax credit or SRECs .
The combination of one or more of the above will reduce your monthly savings as well as the overall payback period of a solar investment.
Now, its entirely possible that despite these factors, you can save thousands or even tens of thousands of dollars over the life of your solar panels just make sure that this is the case before you take the plunge.

Longevity And Sustainability Of Solar Energy
Many people dont realize it, but commercial electrical power is a commodity. Its bought and sold based on supply and demand. When you draw from the power grid, youre subject to current market forces and user rates. Youre not protected from future costs. Thats because futures are unpredictable.
Most futurists predict the world will be less dependent on fossil fuel over the coming decades. Coal and gas-fired electrical generation stations will be more regulated on emissions and their carbon footprint. That means more costs for fossil fuel generation and that has to be passed on to the consumer.
Hydroelectricity is the main power source in areas that have a suitable water supply to turn generators. But the expansion of hydroelectric production means additional flooding. Thats not acceptable in areas where land is a premium. Hydro plants have a limited capacity for output and are already maximized in many stations.
Alternate electrical sources like nuclear plants have dubious futures. Given the volatility of accidents and the nuclear waste problems, the future of nuclear power generation is bleak. That leaves a virtually untapped renewable power source the sun. Solar power is the future solution to low overhead electrical production.

Cloudy Days And Night
On days when there is limited sunshine, your solar panels will not be able to produce as much power as your home needs. At night, your system will not be able to produce any energy at all. If you have a battery, your home can use the energy that your panels have previously created and stored. If you dont have a battery, or your battery becomes depleted, youll consume energy from the grid and pay for it at your usual rates.
How Do I Check That My Solar Panels Are Working Efficiently
Your solar panels are connected to a control panel called an in-home display. This is a wireless device you can use to monitor whether your system is generating as much electricity as it should be.
If youre concerned that your solar panels are underperforming, contact the installer or manufacturer. They can send out a professional technician to investigate.
We dont recommend ever tampering with the solar panels, as this can damage the system and invalidate your warranty.

How Long Do Solar Panels Last
Most standard solar panel warranties ensure that your solar panels will last at least 25 years. As solar panels age, their power output decreases. Its normal for a warranty to guarantee that they will produce over 80% power output at the end of 25 years.
However, this is just a minimum lifetime. Its possible for solar panels to last well over 30 years. In fact, premium panels, like SunPower’s, will guarantee at least 92% power output in Year 25.
If You’re Likely To Move Home In The Next Decade It Probably Doesn’t Add Up
As it takes typically more than 10 years to recoup your installation costs, if you’re considering moving it’s probably not worth it .
While you could physically remove the panels from your old home and install them on the new one, this could prove costly. Plus, while you could still use what you generate yourself at your new address, you’d no longer get paid for what you export. To receive payments your panels need to be certified by the Microgeneration Certification Scheme and the organisation told us it wouldn’t certify panels that have been moved.
It’s also worth noting solar panel installations are tailored to each home to fit the roof and be positioned to maximise the level of sunlight they receive so it’s likely they wouldn’t perform as well if you installed them on a different home anyway.

Calculating The Size Of Your Solar Pv System
Now you know how much power you typically use and the times of day you use it. What capacity will your solar PV system need to be to cover your power usage?
First, we’re assuming you’ll have a grid-connected system. This is by far the most common type and it simply means you have solar panels generating electricity during the day, and a grid connection to supply electricity when the solar panels aren’t generating enough . See grid-connected vs off-grid for more.
How much electricity can you expect per kW of solar panels?
Solar PV systems are rated in watts or kilowatts . You’ll see systems described as 4kW, 5kW, 10kW and so on.
1kW of solar panels = 4kWh of electricity produced per day .
For each kW of solar panels, you can expect about 4kWh per day of electricity generation. So a 6.6kW solar system will generate about 26.4kWh on a good day .
It’s just a general rule the actual amount of electricity generated per kW of solar panels depends on your location, the time of year and the amount of sunlight you’re getting, the quality of the system, the orientation of the panels, how old they are, and so on. In southern regions such as Hobart it could be as low as 3.5kWh per day, while the same 1kW of panels in Darwin could generate 5kWh.

Solar Power For The Home: Costs
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 , metering equipment , 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 . 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 generally need replacement after several years of use.
While the above costs are relatively straightforwardoften a solar installation company can quote a price for these for a homeownerdetermining subsidies available from the government and/or your local utility can prove more of a challenge. Government incentives change often, but historically, the U.S. government has allowed a tax credit of up to 30% of the system’s cost.
Homeowners Guide To Going Solar
Since 2008, hundreds of thousands of solar panels have popped up across the country as an increasing number of Americans choose to power their daily lives with the suns energy. Thanks in part to the Solar Energy Technologies Office’s investments, the cost of going solar goes down every year. You may be considering the option of adding a solar energy system to your homes roof or finding another way to harness the suns energy. While theres no one-size-fits-all solar solution, here are some resources that can help you figure out whats best for you. Consider these questions before you go solar.

How does solar work?
There are two primary technologies that can harness the suns power and turn it into electricity. The first is the one youre likely most familiar with photovoltaics, or PV. These are the panels youve seen on rooftops or in fields. When the sun shines onto a solar panel, photons from the sunlight are absorbed by the cells in the panel, which creates an electric field across the layers and causes electricity to flow. Learn more about how PV works.

What Is The Average Payback Period For Residential Solar Panels In 2021
The solar payback period refers to the amount of time it takes for the electric bill savings from your solar panels to equal the amount you paid for the system. The average payback period for a residential solar system in 2021 is about seven years.
A payback period of seven years equates to a return on investment of approximately 14%. However, this varies greatly by state and even by regions within states.
Calculate the solar panel payback period for your home based on your location, electric use and current local solar system prices
Once you have generated an accurate payback period, you can compare this to the returns you see on other types of investments:
- Long-term government bonds currently have returns between 0.1% and 2%
- Zillow estimates that home prices increase between 3% and 5% annually
- The stock market has risen around 9.5% historically
As you can see, residential solar panels stack up favorably against all of these other investment options – and this is even before we consider the increase in a homes value caused by the solar panel installation.
