How Much Does It Cost Per Solar Panel

What Determines The Cost Of Solar Panels

Cost of Home Solar Panels Installed | How Much Does it Cost For Solar Panels Installed 2018

While the actual costs of solar panels and inverters have come down significantly in the past decade, the so-called soft costs remain high. Such costs include permitting, inspection, interconnection, marketing, sales tax, supply chain costs, and overhead. The costs of PV solar systems differ from state to state largely due to the red tape surrounding permitting, inspection, and interconnection. Even within the same state, the cost of solar panels largely depends on a number of factors. In addition, federal, state, and local financial incentive programs can also determine the final cost of a PV solar system.

  • Solar system size and electricity consumption. Residential solar panel costs can vary based on the size of the system specific to your households needs. The larger the solar system, the higher the installation costs. Your past electricity usage can determine how much solar panels will cost for you. Your electricity consumption every month and the rate your utility charges you for the amount of kW/h used from the power grid determine your electricity bill. To find out how much electricity you consume, you can use this simple formula:
  • Calculate the watts each device uses per day.
  • Convert watts to kW .
  • Determine the kW an appliance uses per month.
  • Figure out the cost by multiplying the kW per month by your electric rate.
  • Types of solar panels. There are three major types of solar panels on the market with different characteristics that determine their prices.

Solar Batteries Are Expensive But May Be Worth It For Those Who Use A Substantial Amount Of Electricity

A solar battery can store any excess power generated by your solar panels that you don’t use at the time, rather than exporting it back to the grid. They aren’t cheap costing about £2,100 for a three kilowatt-hour battery.

The savings you make on your bills can be significant, though. The price you’re paid for each unit of energy you export to the grid is usually much lower than the price you pay your supplier for electricity. So, economically, it makes more sense to store the energy and use it yourself with E.on saying a household with a battery could use 30% more of the electricity they generate themselves.

Another potential advantage of a battery is that it can increase the rate you get paid for exporting your electricity back to the grid. Some firms will pay many times more than the standard amount if you buy certain types of batteries. See what firms pay.

The battery isn’t all about what you generate yourself, either. If you’re on a flexible ‘time-of-use’ energy tariff, with cheaper electricity overnight for example, you can charge the battery at cheaper times from the grid and use it to power your house during more expensive hours.

Are Solar Panels Worth The Investment

Thanks to the lower-than-ever cost of solar panels and various solar incentives, solar panels are a cost-effective investment for the majority of homeowners that will provide an excellent return on investment.

Not only do they lower your energy bills, but you also get to power your home with clean renewable energy and reduce your dependence on your local utility company.

Even though spending up to $20,000 is daunting, federal incentives eliminate 26% of solar system costs after 1 year. There are also various ways to finance a solar system – from solar loans and leases to PPAs – so you can pick whichever option that works best for you.

Plus, solar panels provide significant utility bill savings in most areas. An average home solar panel system can save between $1,000 and $1,600 per year on electricity bills depending on the states net metering policy and the homes energy consumption.

Actual solar savings will depend on the system size, the cost of electricity, home energy usage, and what net metering policies are in place, but the average solar homeowner can expect their solar payback period to be between 8 and 11 years. After that, theyll be enjoying completely free solar electricity for at least 15 more years!

If youre still not convinced, you can use our solar panel calculator to find out how much solar costs and can save you for your specific home based on your average electric usage and prices in your area.

Tesla Solar Roof In Virginia Cost

If your roof is older and needs replacement before installing solar panels or you do not like how solar panels look on your roof, you may want to invest in a Tesla solar roof. Tesla roofs use inactive and photovoltaic tiles that cover the entire roof. This gives it a more cohesive and seamless look than installing panels. Depending on the number of inactive tiles versus photovoltaic tiles and if you use one of Teslas Powerwall batteries, expect costs of between $40,000 and $70,000 to install a 6kW system in Virginia.

When Are Solar Panels Cheapest

Prices vary during the year. For example, between May 2020 and April 2021, prices per kW were highest in April, May and February and lowest between August and October, according to BEIS.

This doesn’t mean that solar panels are always cheaper in the summer though. Spring 2020 prices would have been impacted by Covid-19. In the previous year , the cheapest month was November.

We recommend you get three quotes before you buy, so you have a good idea of the going rate for your installation.

Factors That Affect Solar Panel Costs In Glasgow

Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few major factors that will push your cost above or below the average in Glasgow: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

Solar Panels Tier 1 Tier 2 & Tier 3 Cost Comparison

Solar panel manufactures are broken up into tier 1, tier 2, and tier 3. These tiers basically separate the larger companies from the smaller ones. Another way to say it is Tier 1 are bigger and more well-known producers like Panasonic, Trina, LG, Canadian Solar, etc. and their solar panels cost more than tiers 2 and 3.

This is not to say other manufactures produce solar panels of lower quality, its just the tier ones have been at it for a while not as with a warranty that lasts 25 years, you want to be sure the company is still going to be here if you want to make a claim in 10 years time. So you will pay less for tier 2 and 3 panels, but what is the real cost if you cant claim on the warranty?

Federal Solar Tax Credit

Cost of Solar Panels

One of the significant solar incentives is the ITC, which you can claim on federal income taxes for a percentage of the total price of your solar system. The current ITC rate of 26% is valid through 2022. It will go down to 22% in 2023. To be eligible for the ITC, you must meet the following critical criteria:

  • You have to own the solar panels.
  • The solar system has to be a new installation .
  • You must install your new solar system between January 1, 2006, and December 31, 2023, to claim the ITC in your federal tax filing.

Here is an example of how the ITC can impact the cost of your solar panels:

How Many Solar Panels Do I Need For My House

Average costs of solar panels for a three bedroom house.

According to OFGEM, the average family uses about 3,000 kWh of electricity per year. A 3-4kWp solar panel system should be enough to produce enough electricity for a family of 3 to 5 people. You will need at least 10 m² of roof space.

solar panel prices for the roof of a small house

If you live in a one or two bedroomed house, you won’t need as many panels as a three bedroomed house. A 3-6 solar panel system can generate up to 1800 kWh of electricity per year. A small roof solar pv system like this would need about 10 m² of space on the roof.

How Much Do Solar Panels Cost To Buy And Install

If youre coming to this guide now, having considered solar panels before, know that theyre currently priced lower than they have been in the past. In fact since they took off at scale back in 2010 the price has dropped by a massive 70 per cent. Were referring to the upfront cost of the panels and their installation.

There were previously government grants which meant companies offered solar panels for free. This has since largely ended with just a few remaining. The idea was that they installed and supplied your panels and you got your electricity bills paid for. They took the profits from any excess electricity sold back to the grid usually with a 20-year contract.

The difference now, with government incentives like the Smart Export Guarantee , is that you can cover the cost up front. That means you stand to keep any profits from selling your energy produced back to the grid. This is now more possible than ever since, as mentioned, the prices of panels are at a low. And you could stand to make money in the future.

  • What would have cost you £15,000 back in 2010 will now set you back just £6,000. A big difference that may put solar panel ownership within reach of many that could not afford it before.
  • Take into account that on average a £5,940 setup will save you £339 per year. But lets get more specific.

Solar Panel System Size

How much does solar REALLY cost? Does it have to be expensive in the ...

Its a no brainer that the larger the solar panel system you choose, the higher the installation cost will be. But what factors impact the size of the solar panel system you require? Well, the right size PV system will depend on a couple of factors:

  • The size of your property
  • The available roof space, pitch and orientation of the roof
  • If there are any shading factors
  • The radiation levels of where in the UK you live.
  • And how much energy you use and the amount of energy you want to generate.

It is important that the size of your solar panel system meets your energy requirements, in order to make the switch to solar energy worth while.

Are Solar Panels Worth It

There are a few situations where solar panels are more likely to be worth it:

  • You plan on living in your home for longer than 15 years
  • You have a south-facing roof in a sunny location
  • Youre eco-conscious and wish to lessen your carbon emissions in whatever way possible
  • Youre willing to adjust your energy usage habits to get the most out of your panels
  • Your home is otherwise eco-friendly with quality insulation
  • You use electricity when throughout the day when the sun is shining

Solar panels are being incentivised by the government already, but in the future, there may be even greater encouragement for homeowners to make the switch to renewables.

Those who invested in solar panels some 20 years ago have likely earned much of their investment back already, but since current solar technology is currently ultra-reliable, affordable and efficient, now is a very good time to seriously consider solar.

Its also worth mentioning that solar panels can be added and removed, or even taken with you when you move house. Theyre not permanently attached to a home.

Overall, solar panels are more attractive than ever and most homeowners should consider them if they have a free, sunny roof and are likely to remain in the house for 15 years or longer.

Other Benefits Of Solar Power

Solar panels can be very liberating. The more youre able to power your home entirely with solar energy, the less you have to rely on energy suppliers. If you can capture all the power you need from the sun, youll be living a life of electricity independence.

Most importantly, youll avoid the price hikes that suppliers often impose on their customers.

In late 2021, around 15 million UK households were told their annual energy bills would increase by £139 to £1,277 per year, as a result of Ofgem lifting its price cap.

These caps are revised every six months, which means that another increase might not be far away. Remember: the sun never increases its rates.

Additionally, a self-sufficient, solar-powered household will avoid any power cuts that hit the National Grid. Since Brexit took effect in 2020, the UK has narrowly avoided blackouts on multiple occasions, as Bloomberg has reported.

60% of the UK’s imported gas comes from the EU and Norway, and 91% of our imported electricity comes from the EU. Brexit has made the nation more vulnerable to supply shortages.

How Much Does Labour Cost

The labor cost for installing solar panels is usually factored into your original quote. Solar panel companies will use one of two ways to calculate labour costs.

Most solar power installation companies will charge a flat fee for each installer. If it takes two people one full day to carry out an installation and each installer earns £300 per day, the total cost would be £600.

If you were to have a larger solar pv system installed, the installation cost would double each day.

Some green energy companies prefer to calculate their installation costs by each watt. The average installation cost per watt is 20p. It might not sound like a lot, but when you multiply it by 4000 watts, the final cost would be £800.

The Cost For Solar Panels

How Much do Solar Panels Cost in 2021?

There is no way of assessing the exact cost of solar panels for every individuals home without giving a free site appraisal. Site appraisals are completed to assess anything that cant be viewed online such as if an electrical panel or the roof needs upgrading.

Typically, it is simple to provide accurate estimates remotely using satellite imagery but such methods are not perfect.

Before getting into how much different solar power systems cost, lets realize what goes into a solar installation in Alberta,BC, Saskatchewan or most other places in Canada.

Solar Power System Cost Breakdown

The chart above shows a rough breakdown for solar installations in Canada. Material makes up approximately 70% to 80% of the total job costs, with the biggest culprit being the solar panels themselves.

Installation labour is the next major cost category besides material. Solar installation personnel MUST be certified electricians to install solar modules in Alberta.

The ratios will vary reasonably. If you live in Fort Simpson, NWT, you will have a higher travel expense than a solar installation in Edmonton, AB.

Similarly, if you want a large ground mounted array, there will be more costs for solar materials and labour associated with the groundwork and racking system.

Every job will be a little different, but this should give you a good sense of where your money is going.

How Much Do The Panels Cost

The panels themselves can be bought directly. That means you have the option to install yourself, although this isnt recommended. You could also get a professional to carry out the works using the panels youve bought.

To take a premium panel, lets look at the LG NeON R. This panel has an impressive 25 year warranty, generates nearly 4% more electricity than the competition outputting up to 440W thanks to a 20% efficiency. The other factor to check is what that efficiency is after the 25 year guarantee, above 85% being what youd want at least. In the case of the LG that is an impressive 90%.

  • The average UK household of three needs to produce 3,000kWh per year. That means the need for about 10 panels which requires about 20 square metres of roof space.
  • The LG model costs £318 per panel, meaning 10 panels will cost £3,180 plus installation.

Solar Panel Cost By Manufacturer

Another way to break down solar panel price data is by the panel brand. The following table was made using data from the EnergySage Marketplace and tracks the average cost of 6 kW and 10 kW solar panel systems by the brand of solar panel used in the installation project.

Table: cost of solar panels by panel manufacturer


NOTE: These ranges are system prices BEFORE the 26 percent federal tax credit for solar.

The price you pay for a solar panel brand is reflective of panel quality to a degree. For example, systems using SunPower panels see the highest average prices , and SunPower is known for producing well-made, high-efficiency products.

Interestingly, there arent that many outliers when it comes to brand pricing, and most manufacturers generally see similar cost ranges. Its important to keep in mind that when comparing system prices based on panel brands, there are so many factors aside from just panel manufacturer that impact the final system price like installer experience, location, racking equipment, inverter brand, and more.
