All five of these brands are currently available for much cheaper than many of the best premium solar brands. These brands should be top of your list if youre on a budget but still want a quality solar panel system on your roof.
Wheeling Of Clean Energy
Wheeling is the transfer of electrical power via a utilitys transmission or distribution system between different grid or network service areas. When it comes to solar PV, the areas where the sun is most powerful and consistent is often geographically separate from the urban hubs where electricity is required. This is one of our newest and most exciting solar financing options.
Some Terminology To Understand Before We Start:
I’ll be referring to these later on so it’s worth understanding them if you don’t already.
- kWp Kilowatt peak This is a theoretical maximum output for your solar panels thats quoted by the manufacturers.
- kWh kilowatt hours This is the actual output of your panels. Typically around 80% of the kWp figure .
- MCS Micro-Generation Certification Scheme This is an international quality assurance scheme. If you want to take advantage of the governments financial incentives you must buy MCS accredited panels and have them fitted by an MCS accredited firm.

Planning Permission For Solar Pv Panels Uk
In England, Scotland and Wales you are not required to apply for planning permission for most of the domestic solar panel installations . It is important to note, however, that the installation must be below a certain size. If your pv panels protrude more than 200 mm, you will need to apply for permission first.
Local restrictions
There are also other local restrictions that might affect whether you need permission or not especially in Scotland. For example, when the building is within a conservation area of World Heritage Site. Therefore, it is advised to ask your solar installer to check, whether your installation meets all the requirements.
How Solar Panels Turn Sunlight Into Electricity
In a solar cell, crystalline silicon is sandwiched between conductive layers. Each silicon atom is connected to its neighbors by four strong bonds, which keep the electrons in place, so no current can flow. Here’s the key: a silicon solar cell uses two different layers of silicon.
N-type silicon has extra electrons, and P-type silicon has extra spaces for electrons, called holes. Where the two types of silicon meet, electrons can wander across the P/N junction, leaving a positive charge on one side and creating negative charge on the other.
When one of these photons strikes the silicon cell with enough energy, it can knock an electron from its bond, leaving a hole. The negatively charged electron and location of the positively charged hole are now free to move around. However, they have only one way to go because of the electric field at the p/n junction. The electron is drawn to the N-side, while the hole is drawn to the P-side.
The mobile electrons are collected by thin metal fingers at the top of the cell. From there, they flow through an external circuit, doing electrical work, like powering a lightbulb, before returning through the conductive aluminum sheet on the back. Well, thats it the physics behind solar magic.

How To Install Solar Panels In 7 Steps
1ST STEP ASSEMBLE AND MOUNT THE SCAFFOLDING
The first step in the process is to erect the scaffolding. This will ensure safety for the installation team when they are on the roof
2ND STEP ATTACHING ROOF ANCHORS
After the scaffolding is set, the installation team arrives. The team starts out by attaching the roof anchors, which will hold the base for the solar panels. The types of anchors used depends on the type of roof tile fitted on the roof. We sell Schletter, Renusol, IBC and K2 solar mounting systems.
3RD STEP ATTACHING THE FRAME
The next step is to attach the frame, which is made up of aluminium bars. The bars must be fitted in a straight direction and parallel to one another.
4TH STEP INSTALLING THE SOLAR PANELS
Once the frame has been attached, the installation of the solar panels themselves can begin. The panels are clamped to the aluminium frame, but initially not too tight so as to permit adjusting on the frame. Once they are set up at the desired position, these will be firmly anchored.
5TH STEP WIRING THE SOLAR PANELS
6TH STEP FINAL CONNECTIONS TO THE CONSUMER UNIT
After the panels are wired to the solar inverter, the final connections to the consumer unit will be made. A generation meter will also be connected, whose purpose is to monitor how much electricity the solar panels actually produce. During the time of the wiring installation, the electricity supply to the household will need to be shut off.
7TH STEP TESTING THE PANELS
Solar Panels Reduce Air Pollution
Solar panels transform sunlight into clean energy. Installing a solar panel on your home helps reducing greenhouse gas emissions and reduces our collective dependence on fossil fuels. Traditional electricity comes from fossil fuels such as coal and natural gas. When fossil fuels are burned to produce electricity, they emit harmful gases that are the main cause of air pollution and climate change. Fossil fuels are not only harmful to the environment, they are also a limited resource. As a result, their price fluctuates constantly and can increase drastically.

Solar Panels Purchase: Cash Or Loan
When it comes to owning your own system and having full control, as we have already mentioned, your options are either to buy outright or to take out a solar loan. If you have a good credit score rating, loans provide another great option for owning solar that takes away some of the financial burden of paying for the system in the form of set monthly instalments and a low down payment.
The main negative when we are comparing the two is that due to the interest required with pretty much any loan type including solar loans, you are going to be paying more overall for the cost of your system compared to purchasing it with cash. Another negative aspect is that if you fail to meet your payment terms over the course of your loan agreement, this could lead to your system being repossessed and the outstanding amount on your solar loan still being due until paid in full.
Even though the system is entirely in your name and you can essentially do with it as you wish when you have entered into a loan agreement, the system is never truly yours until the final payment has been made on your loan. Where possible, paying cash for your system and taking immediate ownership is the best option for those who want to go solar and will always yield the best price when compared to paying over time and the interest rates that come with this.
Other Parts Of Solar Panels:
A solar panel is not only made out of solar cells. It typically includes a durable glass housing which protects the silicon PV cells. Under the glass exterior lies an insulating layer as well as a protective sheet to hinder heat dissipation and prevent moisture build-up inside the panel. Insulation is important because an increase in temperature will lead to a decrease in efficiency, which will reduce the performance of the solar panel.
Solar panels also have an anti-reflective coating that increases sunlight absorption and allows the silicon cells to maximize their sunlight exposure. Silicon solar cells come in two varieties: monocrystalline or polycrystalline. Monocrystalline cells consist of a single silicon crystal, while polycrystalline cells are made out of fragments or chips of silicon. Monocrystalline panels give electrons more space to move around and are therefore more efficient compared to polycrystalline panels. However, this comes at a cost: Monocrystalline panels are more expensive.

Solar Panels: A Brief Historical Overview
Solar energy technology is not a new discovery. It goes back to the mid-1800s, to the industrial revolution, when solar power plants were developed to heat water and create steam to power machines. The development of solar cell technology, or photovoltaic technology, began during the Industrial Revolution when French physicist Alexandre Edmond Becquerel first demonstrated the photovoltaic effectthe ability of a solar cell to convert sunlight into electricityin 1839. About four decades later, American inventor Charles Fritts created the world’s first rooftop solar panel in New York in 1883, one year after Thomas Edison opened the first commercial coal-fired power plant. The panels were then covered in selenium and did not produce much current. However, the process of electricity production by light was not fully understood until Albert Einstein wrote his groundbreaking article on the photoelectric effect in 1905 that won him the Nobel Prize in Physics in 1921.
How Many Solar Panels Do I Need
To determine what size system will best fit your needs, make a list of all the appliances and devices you plan on running. The main appliances to take into consideration when addressing energy needs may include a TV, lighting, water pump, laptop, fans, microwave, and refrigerator. We recommend inputting that information into the Renogy solar panel calculator to help determine your specific solar panel needs.

How Solar Panels Work
First, how do solar panels work? Solar panels are made of photovoltaic cells. The sun emits solar radiation, which is absorbed by the PV cells when the sun shines directly on them. The energy from the sun creates electric charges, which move according to the electrical field in the cell, directing the flow of electrical energy. Parts of the solar panel also convert energy from direct current to alternating current so it can be used in homes. Certain solar panel array components also store the energy for later use even when the sun is not up. You can learn more about how solar panels work in our guide.
If They Dont Ask Dont Buy
Reputable solar installers will always ask homeowners about the age and condition of their roofs and will inspect them to ensure they are up to par, says Heaven Campbell, Solar United Neighbors Florida program director.
They will not install on a failing roof or one that wont meet wind code requirements, Campbell says. There are standards they follow per the instructions of the equipment and state and local permitting processes. Any company not asking about the roof is a fly-by-night company and likely from out of state. I havent heard of this happening and it would be a super rare bad actor.
A roofs lifespan mostly depends on what kind it is. Asphalt shingle roofs are cheapest to install but have the shortest life, Weisleder says. They wear out faster as the sun beats on it. Ive seen some last 25 years, while others start getting soft at 15 years, he says.
Next comes clay ceramic tile, which should last a minimum of 25 years, and then metal roofs, designed to last 30 to 40 years, he says.
Home insurance companies in Florida are scrutinizing ages of roofs more closely. A new law allows insurers to refuse coverage for homes with roofs 15 years old or older unless the homeowner can produce an inspection report stating the roof has five years or more of useful life.
That means a lot of roofs will need to be replaced in coming years, and if yours has solar panels, youll be paying to remove and reinstall them as you pay for your new roof.
