What Are The Labour Costs
When you are given a quote for your solar panel system, labour costs are typically included. There are two common ways of calculating the labour costs for solar panel installations in the UK.
One way is to calculate approximately £300-£500 per person, per day. As it usually requires two people to install the system, a final installation fee is normally £600-£1,000. If you are installing a larger system, it may take more than one day and the costs will naturally rise.
Another way to calculate the installation fee is to charge 20 pence per watt. So, for a 4kW system, you would be paying 20 pence for 4000 watts, resulting in £800.
What Happens To Solar Panels After 25 Years
The degradation rate is the rate at which solar panels lose efficiency over time. This means that after 25 years of use approximately 4 out of 5 solar panels still work with 75% or higher efficiency. At this point, it is fair to estimate that your solar panels will continue to produce energy at a certain capacity, long after the warranty expires.
Are Solar Panels On Cars The Answer
Even as manufacturers increase the range of their EVs, some owners and potential buyers are wondering if there are other ways to increase the range of electric vehicles. Invariably solar panels come up as an option. The typical thought pattern is Sunlight is free and plentiful everywhere, right? Adding a few solar panels to the top of your electric vehicle would let you drive indefinitely and at no cost. Why hasnt Toyota done that yet?
In reality, its not that simple. Yes, solar panels can provide electricity anywhere they go no need for a gas station or electricity grid to charge up. Powering cars with solar is possible, and weve all seen pictures of Halle Barry from the 90s next to those weird looking solar racing cars
Those strange-looking cars are specially designed to run off solar energy. They sport huge, flat roofs to fit as many solar panels as possible. Theyre ultra-lightweight to reduce electricity use. They only fit one person. Theyre also pretty slow . This is the kind of setup that you need to have a car totally running off the sun. Not very practical, is it?
That doesnt mean that solar panels on cars is a complete wash. In fact, at least two major manufacturers are already making cars with solar panels.

Benefits Of Solar Panels
There are many advantages of solar energy to consider when youre deciding whether or not to install solar panels, such as:
Power Small Appliances With Solar Energy
Don’t stop at powering your devices with solar. You can also power your small kitchen appliances — like your coffee maker, toaster, Instant Pot, slow cooker or sandwich maker — without plugging them into a wall. While the monetary savings on your electricity bill will be small, the planet will still benefit from your use of renewable energy. Plus, during blackouts you’ll still be able to cook.
All you’ll need is a 25-watt power bank you can stick in a window and a DC-to-AC inverter to make it happen. The inverter simply plugs into the power bank, so it’s very easy to set up.
If you want an all-in-one solution, Goal Zero makes solar power kits with large storage batteries. It has everything you need to power your small appliance.
Once you have it set up, just plug your small appliance into the power bank. They’ll run just like normal. The only drawback is that you can only power one appliance at a time, unless you have multiple power banks.

Solar Panel System: How To Build A Cheap One
A cheap solar panel system will forever be the best solution to expensive electric bills. Solar cells are getting cheaper each year.
While you could pay up to $10,000 for an off-the-shelf installation and could cover the systems price in just over 10 years, its still better and more educational to make one yourself.
Lets face it: were still living the post-traumatic stress of what happened in 2008, and were still living uncertain times when every cent we take from the bank is thoroughly analyzed before we actually sign a contract. The lack of financial stability has caused astute savings among those who learned how to save what they have, including energy.
Were living in a war right now. The battle for energy efficiency has never been fought with more advanced weaponry, and the winners are all those who pay less for more month after month after month

The first line of defense against paying more for electricity than you did last year is building your own solar panel system. Yes, you may have heard of Solyndra collapsing and may have even thought, at least once in your lifetime, how it would be like having your own solar panels mounted in your backyard or on your homes rooftop.
Theres a problem: how to you recover the costs within a couple of months?
Well, theres a solution to that: build your own DIY solar panel system. Heres how:
Reduce Solar Panel Costs With Seg Payments
In the UK, you can reduce your solar panel costs even more by making use of solar panel grants, like the Smart Export Guarantee . Through the SEG, you can earn money for exporting surplus solar power that your panels have generated back to the national grid.
The tariffs for exported solar energy can vary from supplier to supplier, but a good rate is 4-6p/kWh.
SEG generators that are seeking further guidance, you can read this guide on Ofgem’s website.
If you have a 3kW system installed, you can earn £75 per year through the SEG. With a 4kW system, you can expect annual earnings of £100, and with a 5kW system you can earn £120 per year.
Before the SEG came into play, the Feed in Tariff was the main solar panel grant available. Those that are already registered under the FIT can continue to receive payments, but the FIT ended in 2019, and no new applications are being accepted.

When To Install Solar Panels
Contrary to popular belief, winter is actually the best time to install solar panels. There is simply less demand for this service in winter, so the installation should cost less as a whole. Even if you live in a region that tends to be cloudy and/or chilly, your solar panels will still be able to generate energy and in some cases, will even generate more energy than they would in warmer months.
Installing solar panels during winter is, in addition to being cost-effective, efficient. With installation companies doing fewer jobs in the off-season, your panels are likely to be installed faster, and will be up-and-running in no time.
How Many Solar Panels Will You Need
To know how many solar panels you will need, you will want to determine how much electricity you use in your home and the solar panel types installed.
The average house in the United States uses about 900 kilowatt hours a monthroughly 11,000 kWh a year. You can easily calculate your actual usage by looking back at your electricity bills. As a general rule of thumb
- A 3-kWh solar panel system will generate about 3,600 kWh 4,800 kWh per year.
- A 5-kWh system produces about 6,000 8,000 kWh per year.
- A 10-kWh system can produce about 12,000 kWh 16,000 kWh per year.
Depending on the size of the system, the solar panels cost would be between $4,000 and $16,000. Add in another $3,000 to $10,000 for other necessary components, such as racks for the panels, wiring, solar inverter costs, and the total solar panel installation cost would now be closer to $20,000.

LG doesnt just make solar equipment theyre one of the leading electronics manufacturers in the world.
We feature LGs 375W panel in our premium packaged systems. They are super space-efficient, packing more output into a 60-cell panel than most 72-cell panels on the market are capable of producing.
Every solar project is different, and some people have the challenge of building a system in a compact space. For example, you may only have room for 10 panels on your roof. These LG panels will help you squeeze as much output as possible out of the limited space available to you.
They also have a long lifespan. At -0.4%/year, the degradation rate of these panels is 0.3% better than our featured Astronergy 365W panel.
That may not sound like a lot, but when you work the math out, it means LG panels will retain 7.5% more efficiency than Astronergy panels at the 25-year mark.
And LGs solar panel warranties are a thing of beauty.
Where most companies aim for a 10-year workmanship warranty, LG covers the full 25 years.
On the performance warranty side, LG ensures their panels will still be 90% efficient after 25 years. Thats a stronger promise than the standard 80% after 25 years.
Why Do Solar Panel Costs Vary
Although individual solar panel prices are listed, normally when solar installers order materials for installation, they might be able to find a better deal because of relationships they have with manufacturers or through various incentives for solar in your state.
Find what solar incentives you could be eligible for here.
When buying solar panels for a project, the cost per watt of the panel can end up being less than if you bought 20 individual panels. Working with a licensed installer can help you get the best quality panel for the best cost.
Additionally, while cheap solar panels offer the best price upfront, they might not be the best long-term option. Cheap solar panels have a shorter lifespan because usually what makes them cheap is that they have lower efficiency, or ability to absorb sunlight, and they deteriorate more quickly.
However, if you are determined to get the best deal for solar panels, going the DIY route might be your best bet.

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.
Teslas Customer Service Comes Up Short
Its true that youll probably get the lowest price for going solar when you go with Tesla. But the price of solar also includes the cost of the long-term relationship that you get with your solar installer, and that seems to be where Tesla cuts costs.
Unfortunately, Tesla has historically been known for having pretty shoddy long-term customer service – which you can read about in customer reviews here on SolarReviews. Because they are such a large company, they don’t have the ability to give you the type of one-on-one service that you need when going solar.
Teslas customers have reported that its hard to get ahold of them if theres a problem with their system, and it can take even longer to get someone out to check on the issues. This can actually cause you to lose a substantial amount of money.
If your solar panels arent producing energy properly, you have less electricity to power your home, and thus a higher electric bill. The longer it takes for someone to fix your system, the more money you lose.
