If You Decide Solar Panels Are Right For You Find A Registered Installer And Get Three Quotes
As we’re MoneySavers, not electricians, picking installers isn’t our speciality. You can see the firms shortlisted for the British Renewable Energy Awards 2020, run by the Renewable Energy Association, or ask friends and colleagues for recommendations.
The system and the installer should meet the standards of the Microgeneration Certification Scheme . And make sure the installer is a member of the Renewable Energy Consumer Code.
As always, get at least three quotes, and get ’em in writing. When comparing quotes, check the following are included: scaffolding, removal of the existing roof and other roofing works, internal wiring works, sorting out a connection agreement with the energy supplier, electrical connection work, and a generation meter. Fitting the panels themselves is a one or two-day job.
Once they’re fitted, registering your panels is a must you’ll need an MCS certificate, which you’ll use to register for smart export guarantee payments with a licensed energy supplier.
Never borrow from solar companies to pay for the panels
Some installers let you buy solar panels on credit. If you don’t have the cash upfront, panels aren’t for you. The loan’s interest could dwarf the savings.
Solar panels are generally low maintenance
The Energy Saving Trust says little maintenance is required on a properly installed, well-designed solar PV system, though you’ll likely need to replace the inverter a gadget that is a key part of the mechanism within about 25 years .
Most New Wind And Solar Projects Will Be Cheaper Than Coal Report Finds
Almost two-thirds of renewable energy schemes built globally last year expected to undercut coal costs
Almost two-thirds of wind and solar projects built globally last year will be able to generate cheaper electricity than even the worlds cheapest new coal plants, according to a report from the International Renewable Energy Agency .
The agency found that the falling cost of new windfarms and solar panels meant 62% of new renewable energy projects could undercut the cost of up to 800 gigawatts worth of coal plants, or almost enough to supply the UKs electricity needs 10 times over.
Solar power costs fell by 16% last year, according to the report, while the cost of onshore wind dropped 13% and offshore wind by 9%.
In less than a decade the cost of large-scale solar power has fallen by more than 85% while onshore wind has fallen almost 56% and offshore wind has declined by almost 48%. Francesco La Camera, Irenas director general, said the agencys latest research proved the world was far beyond the tipping point of coal.
He said: Today renewables are the cheapest source of power. Renewables present countries tied to coal with an economically attractive phase-out agenda that ensures they meet growing energy demand, while saving costs, adding jobs, boosting growth and meeting climate ambition.
Keep An Eye On Trade Policy
Changes in government trade policy also impact prices. In January 2018, President Trump imposed a four-year tariff on imported solar cells and panels that started at 30% and was set to drop 5% each year until February 2022. In 2020, the tariff rate for the fourth year was raised from 15% to 18%. The tariff resulted in a 16 cent per watt increase for the average consumer in 2018, which translated to an overall increase of $960 for a six-kW system, according to EnergySage.
The cost of foreign-manufactured panels may still drop, lessening the tariffs effect over time.

Cheap Renewables Are Good News
IRENAs report, Renewable Power Generation Costs in 2020, finds that costs for renewable technologies are continuing to fall significantly year-on-year.
Today, renewables are the cheapest source of power, said IRENAs Director-General Francesco La Camera.
Cheaper renewables give developed and developing countries a compelling reason to phase out coal while meeting growing energy demands, saving costs and adding jobs, IRENA said.
Retiring costly coal plants would also stop the emission of about three gigatonnes of CO2 a year 20% of the reduction in emissions needed by 2030 to avert climate catastrophe.
Emerging economies will save up to $156 billion over the lifespan of the renewable projects added in 2020 alone, the agency added.
How Long Do Solar Panels Take To Pay For Themselves
Depending on the size of your solar panel system and the export tariff, your solar panels can be paid off after 15-25 years. A larger system is more expensive, but it can generate more electricity and, therefore, can bring you more savings in the long-run.
A 5kW solar panel system can break even after 15-20 years, while a 3kW system can take 21-25 years to break even.
To protect the lifespan of your panels, ensure you always adhere to solar panel maintenance and cleaning tips.

An Aside On Solar Leases And Power Purchase Contracts
Back to those power purchase agreements for a minute. As solar has become more cost competitive , the market for third-party owned solar arrays has boomed. In simple terms, this means you have a solar array on your roof, but someone else owns it. You either lease the solar array to get the solar energy or buy the solar energy on contract. Many of these providers offer customers a lower price for electricity than they pay to the utility. Great, right?
Perhaps not. Many of these contracts have an inflation escalator. A reasonable one might assume that the price of grid power will climb by 2-3 percent per year and the customers price will mirror that. But some contracts assume much higher price inflation, 5% or 6% or 7%. Electricity prices have rarely increased that fast over a long period of time, which means that the solar customer may actually end up paying more for their solar energy than if they had stayed with the electricity from their utility. For many customers, that wont matter. But as solar goes mainstream, the price comparison will be that much more important.
Evaluate Your Sunlight Exposure
More sun means more energy produced and a greater potential to save with solar. Certain states, like Arizona and California, average more sunlight hours per day.
Your home’s orientation toward the sun, the amount of shade and its roof type also affect a solar system’s output. You can estimate the efficiency of panels in your area by using the SolarReviews calculator. Enter your address and the average cost of your monthly energy bill.

New Solar Opportunities For A New Decade
Since the Solar Energy Technologies Office launched the SunShot Initiative in 2011, solar has made great strides in the United States. In early 2011, solar power comprised less than 0.1% of the U.S. electricity supply with an installed capacity of just 3 gigawatts. As of 2017, solar now supplies more than 1% of U.S. electricity demand with an installed capacity of more than 47 gigawatts.
The solar office has continuously worked toward its goal of enabling solar electricity costs to be competitive with conventionally generated electricity by 2020, without subsidies. During this time, the solar industry has seen tremendous progress in cost reduction. In 2017, the solar industry achieved SunShots original 2020 cost target of $0.06 per kilowatt-hour for utility-scale photovoltaic solar power three years ahead of schedule, dropping from about $0.28 to $0.06 per kilowatt-hour . Cost targets for residential- and commercial-scale solar have dropped from $0.52 to $0.16 and from $0.40 to $0.11 per kWh respectively.
The 2030 goals were announced on November 14, 2016. Read the press release and that highlights the 2030 goals.
Solar Power For The Home: Benefits
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. The National Renewable Energy Laboratory produces maps for the U.S. showing solar irradiation levels the tools on its website provide detailed solar information for specific locations within the U.S.
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 final benefit is the potential effect on a home’s value due to the addition of a solar array. In general, it is reasonable to assume that solar panels would raise the value of most homes.

How Much Do Solar Panels Cost Let’s Take A Look
Switching to solar power is a proven method for reducing your environmental footprint, energy burden and reliance on traditional utility companies. However, even though the cost of solar has dropped 80% in the last decade, the upfront cost of solar panels is still significant. When selecting the best solar company for your home installation, price is one of the largest factors.
But what is the average cost to install a solar energy system? What are some of the factors that can impact pricing? How much would it cost me, specifically? In this article, we’ll answer questions like these with the goal of helping you make a fully informed, responsible decision about a solar energy investment for your home or business.
If you’re looking to work with a solar installer, we recommend getting quotes from a variety of providers. Use this tool to get matched up with local solar companies in your area, or fill out the form below.
The Cost Of Solar Panels Vs The Cost Of Doing Nothing
Sticker shock can be common when looking at solar proposals. But it’s important to understand that by purchasing a solar system, you’re essentially paying for 25 years of electricity upfront. So make sure to think about what you’d spend on future utility bills to see whether solar panels are worth it for your home.
For example, taking an average monthly electricity bill of $125 , I could theoretically expect to spend $46,837 on conventional energy over the next 25 years if utility rates continue to increase around 1.8% each year, the current average according to the EIA.
EcoWatch
To put this in perspective, based on the average cost of solar per watt in Louisiana, a solar system that offsets my energy usage would cost around $15,214 after the tax credit .
Granted, not all solar systems will offset 100% of your energy use each month, but a modest solar array can be expected to offset at least 50-75% when properly designed and installed. How does that compare to spending $50,000 on dirty and unreliable energy over the next few decades?

In the above-mentioned Sustainable Development Scenario, clean energy policies and investments grow exponentially, bringing the grid much closer to achieving sustainable energy goals, including the ones set by the Paris Agreement .
The new Net Zero Emissions by 2050 Scenario is an extension of the Sustainable Development Scenario, in which all countries that have goals to achieve net-zero emissions by 2050 achieve those goals, and the entire planet is brought to net-zero emissions by 2070.
In the Stated Policies Scenario, in 2021, the coronavirus gradually is brought under control, and the economy returns to the state it was in before the pandemic, reflecting actual current goals of many governments.
And finally, the Delayed Recovery Scenario is similar to the Stated Policies Scenario, but envisions a world where the pandemic persists past 2021 , and more permanently damages the global economy.
Whether this upheaval ultimately helps or hinders efforts to accelerate clean energy transitions and reach international energy and climate goals will depend on how governments respond to todays challenges, the IEA concluded in a press release.
How Much Have Solar Energy Prices Fallen
The section above describes the drop in installed home solar costs, but what about just the panels?
The price of solar panels has dropped by an incredible amount. Back in 1977, the price of solar photovoltaic cells was $77 for just one watt of power. Today? You can find solar cells priced as low as $0.13 per watt, or about 600 times less. The cost has generally been following Swansonâs Law, which states that the price of solar drops by 20% for every doubling of shipped product.
This relationship between manufacturing volume and price is an important effect, because as youâll see, the entire global economy is shifting rapidly toward renewable energy.
As you see in the graph below, the past 20 years have been a time of incredible growth for distributed solar. Distributed solar refers to small systems that are not part of a utility power plant – in other words, rooftop and backyard systems on homes and businesses throughout the country.
This graph shows how many systems were installed per year. As you can see, there was a relatively small market in 2010, and it has exploded in the years since. While there was a drop in 2017, the growth curve in 2018 and early 2019 has continued upward.
Swansonâs Law describes how this massive growth has also led to a massive drop in price: solar module costs have dropped by 89% since 2010.

The Price Of Solar Electricity Has Dropped 89% In 10 Years
To curb our climate crisis, we need to end our dependence on fossil fuels and power the world with renewables. That may have seemed far-fetched a decade ago given the cost of installing wind and solar at the time, but the price of renewables has been falling fast. In 10 years, the price of solar electricity dropped 89%, and the price of onshore wind dropped 70%.
Clean energy has already passed its economic tipping point. A 2019 report from the nonprofit Rocky Mountain Institute found that it was cheaper to build and use a combination of renewables like wind and solar than to build new natural gas plants. A 2020 report from Carbon Tracker found that in every single one of the worlds energy markets, its cheaper to invest in renewables than in coal.
Our World in DataOur World in Data
In 2009, building a new solar farm was 223% more expensive than building a new coal plant. Now, its flipped: Electricity from a new coal plant is 177% more expensive than electricity from new solar panels. What caused the switch? Huge leaps in technological advancement. To understand why solar power got so cheap we have to understand why solar technology got cheap, Roser writes.

Is Solar Power Cheaper Than Coal And Other Fossil Fuels
Comparing the cost of various energy sources is far from simple. Government subsidies play a major role in shaping the growth potential for a new power source, which means that making an apples to apples comparison of the costs of solar energy vs. fossil fuels side-by-side is a complicated task.
G20 vs the U.S.: the fossil fuel paradox
The nations of the Group of Twenty may have agreed to begin phasing out fossil fuels in 2009 due to its inefficient and polluting qualities, but not every G20 member is following through on its word. According to Oil Change Internationals report, while the G20 makes up more than 85% of global GDP, these top economies are spending $452 billion every year to subsidize fossil fuels.
Curious to know who is the largest contributor of fossil fuel subsidies in the world? The answer is right here at home. The United States has continued to subsidize fossil fuels at a higher rate than any other nation in the world, even under the environmentally progressive Obama Administration. With fossil fuel advocates already lined up for the incoming Trump Administration, the next era of American energy will likely continue on its same course of heavy fossil fuel subsidization.
How energy subsidies play the biggest role
When we compare the cost of solar energy vs. fossil fuels, we have to factor in the relative subsidies that are keeping costs low. In the case of solar power, the Investment Tax Credit currently covers 26 percent of any U.S. solar installation.
The Price Of Solar Equipment Has Dropped By 89% Since 2010 But Recent Raw Material Shortages Have Reversed That Trend
If youâre interested in solar and renewable energy, youâre probably aware that the price of wind and solar technologies have dropped by an incredible amount over time.
There are a couple questions that homeowners who are thinking of going solar often have. The first is: Is solar power getting cheaper? And other is: If solar is getting cheaper, should I wait before installing solar panels on my house?
The price of solar panels, inverters, and lithium batteries has gotten cheaper over the past 10 years. Prices are expected to continue to drop over the long term.
However, the cost of solar installation will not drop at the same rate because hardware costs are less than 40% of the price tag for a home solar setup. Dont expect home solar to be dramatically cheaper in the future. In fact, your cost may increase as local and federal rebates expire.
Recent shortages in key raw materials, especially polysilicon, have actually caused the price of solar panels to actually rise in the past year. While this trend is expected to be temporary, it does illustrate that solar panel prices can fluctuate.
Bottom line: if youre thinking of adding solar to your home, waiting probably isnt going to save you money. Install your solar panels now, especially because tax credits do expire.
