Nowadays, everyone should know that solar panels, as well as a source of renewable energy, can actually make a home money through government subsidised feed-in tariffs. But what if a home has a flat roof? Can solar panels be effective and safe when installed on a flat surface?
The answer is yes. But there are many things to take into consideration when planning a PV installation on a flat roof.
As UK homeowners know, planning permission affects most home alterations. Solar panels are listed as a permitted development in the UK, which would usually mean no planning permission is required. However there are rules that must be adhered to, even with permitted development rights in play.
When installed on a house with a sloped roof, the PV panels must not protrude more than 20cm from the surface of the roof. But on flat roof, the panels need to be placed at an angle to maximise exposure to sunlight, and to prevent rainwater from gathering on the surface.
The optimum angle is around 25 – 30 degrees. This means that the panels will almost always be over the 20cm limit.
Therefore if the owner of a flat roofed home is planning on investing in solar, planning permission will almost always be required and the best solar companies can usually take care of the process. It is also worth noting that permitted development rights can vary from council to council, if they issue an article 4 direction. these directions are usually put in place to protect the character of an area, and are most often issued in conservation areas.
For safety reasons, PV panels must be secured to the roof in the correct way. Britain’s temperamental weather can make the exposed surface of a roof an incredibly windy place. On a flat roof it is usually best to ballast the panels, as opposed to bolting them into the surface of a roof, which could potentially damage the weather proofing of a building.
An structural engineer will calculate the wind load of a roof, and ballast the panels in a safe way, using the correct amount of weight to counter the weather in any given area.
Be aware that flat roof installations tend to not last as long as the 20-25 year estimate that applies to installations on sloped surfaces, although they still have an impressive life span. Repairs may be needed more regularly, as roofing laminate may have to be replaced, and ballasts may need to be reconfigured.
Photovoltaic solar panels are not just good for the environment. an investment now will double a homeowners money over a 25 year period, showing that feed-in tariffs can actually increase a home’s income, as well as cutting an average of 70 a year from energy bills. so all in all, spending the time and money installing PV panels on a flat roof is still an extremely worthy investment.

Climate change campaigner Peter Fuchs is determined to challenge planners who want to stop him putting solar panels on the roof of his barn.
Mr Fuchs, son of polar explorer Dr Vivian Fuchs, believes everyone must try to do what they can to protect the global environment.
-
But planning officers at Harborough Council say his proposed panels would ruin the look of the surroundings in picturesque Dunton Bassett.
Mr Fuchs wants to install 17 panels on the listed outbuildings to help reduce the carbon footprint in the village and is determined to fight on.
Mr Fuchs said: “We have to balance the major issues posed by climate change with protecting our heritage.
“I am angry the planning officers said what I am proposing would have an adverse impact on the building, my home and the village.
“The panels would be installed on the roof of a barn which we have restored and would be out of the way and only visible from a limited vantage point.
“I am determined to see this through as I feel so strongly we must all do what we can. I would like to see many more micro generation schemes being promoted, including mini wind turbines on houses and the use of thermal energy.”
Mr Fuchs, who is also a former district councillor, runs a foundation which helps send students to study the polar regions and the impact of global warming.
He said the village had formed a group called Dunton Goes Green, which is aiming to make the community carbon neutral in 20 years.
He said: “I hope to be the 11th person in the village to have solar panels installed on my property.”
Village resident Judith Godfrey, who had 13 solar panels fitted to her roof in July, supports the application by Mr Fuchs.
She said: “We all have to do what we can to reduce our carbon footprint. The scheme being put forward by Peter Fuchs will be hardly noticeable and should be granted.”
Ward councillor Neil Bannister has called for a site meeting so planning committee members see the location.
However, a planning officer recommended the scheme be refused by the committee when it meets tomorrow.
In a report, he said the proposal would be unsympathetic to the attributes of the outbuilding and the home.
He said: “The roof of the listed outbuilding is considered to be part of its special interest.
“It is considered that approval of this application would set an unwelcome precedent.”

Yesterday, Science Magazine hosted a debate about the application of nanotechnology to the development of solar cells. There are hopes that nanotechnology can bring solar power’s prices down to fossil fuel price level.
On the discussion panel were Alan Heeger, a physicist at the University of California who shared the 2000 Nobel Prize in Chemistry for his work on electrically conducting plastics, and Deli Wang, a materials scientist at the University of California, San Diego.
Both focus their research on related to technology. Alan develops solar cells from plastics and other organic materials while Deli tries to develop solar cells using tiny inorganic nanowires.
Alan is an optimist. he believes solar cell technology will be contributing significantly to our energy needs by 2020 as costs are dropping rapidly.
Deli said the efficiency of nanowire solar cells have been increasing dramatically in the past few years, from tenth of 1% to 15-16%. still lower than the best Si cells (silicon), but it’s improving fast.
He added the main challenges faced by nanowire solar cells include managing the surface states of nanowires to reduce the surface recombination, including finding the right materials, and designing/fabricating devices that allow the effective carrier collection.
As people who follow solar power development are aware, efficiency is the industry’s Holy Grail. Alan said the main problem is the need for new materials.
“We need materials with a smaller energy gap to provide better harvesting of the solar radiation. we need materials with higher mobilities so that we do not lose the photogenerated carriers by recombination before they are extracted at the electrodes” he said. he noted the efficiency of organic solar cells (the ones not made of silicon, the industry standard) is growing steadily and current record values in the lab are approximately 10%.
He added that organic PV technology is not a direct competitor with conventional Si solar cell technology. the organic cells are light weight, flexible and rugged. besides, they can be made semitransparent. for that reason, organic PV can be used in a range of products that are not possible with Si cells, such as semitransparent windows as well as the covering and powering of green houses. he expects organic solar cell panels to be on the market well before 2020 in a growing number of specialized applications.
In terms of the advantages of nanowire solar cells, Deli said these and other nanomaterial solar cells require less materials compared with single crystal Si cells. the new materials are made by low-cost process, such as solution method, and cheaper device processing (e.g. printing). Si cells require high purity and more materials, therefore larger capital and energy is necessary to produce them. new nanomaterials are light weight, portable and flexible. A wide range of materials can be used, including organic conjugated polymers. best of all, it is possible to develop new materials with elements that are abundant in the earth.

FREMONT, Calif. & MUSCAT, Oman–(BUSINESS WIRE)–GlassPoint Solar, the leader in solar enhanced oil recovery, has received the Platts Global Energy Commercial Technology of the Year award. Open to commercially applied innovation, GlassPoint’s solar enhanced oil recovery (EOR) solution was selected for its practicality, reliability and overall commercial success.
“Platts’ acknowledgement validates our technology and the impact solar generated steam will have on future oil production.”
“In the past year, we’ve brought solar EOR from concept to commercial reality. now, we’re actively scaling worldwide from California to the Middle East,” said Rod MacGregor, GlassPoint CEO and President. “Platts’ acknowledgement validates our technology and the impact solar generated steam will have on future oil production.”
MacGregor was presented with the award last week in new York at the Platts’ Global Energy Award ceremony among 500 international energy professionals. in its thirteenth year, the annual Platts Global Energy Awards honor the energy industry’s “Best of the Best,” showcasing extraordinary accomplishments by energy businesses and individuals worldwide. more than 200 nominations were received for this year’s awards program in 19 performance categories. Other 2011 recipients include Royal Dutch Shell, Chesapeake Energy and Dow Chemical.
The world’s major oil producing regions are increasingly turning to EOR to economically recover more from oil maturing fields. The most popular form of EOR is thermal EOR, a technique in which high-pressure steam is injected into an oil well so that more oil can be pumped to the surface.
The steam required for thermal EOR operations is obtained by burning large quantities of natural gas. GlassPoint’s steam generators reduce thermal EOR gas consumption by up to 80 percent. in addition to reducing the cost of heavy oil production, gas that would otherwise have been used for EOR can be applied to higher value applications, such as power generation, desalination and export.
GlassPoint’s proprietary Single Transit TroughTM (STT) technology produces solar steam at a lower cost than steam produced by burning natural gas. The STT design places the solar array inside a glass enclosure, protecting it from the dust, sand and humidity commonly found in oil producing regions.
in February, GlassPoint began operation of the world’s first commercial solar EOR project with Berry Petroleum in Southern California. in August, the company announced the award of a contract to build a 7MW solar EOR facility for PDO (a joint venture between Shell, Total and the Sultanate of Oman).
Platts’ independent panel of judges included former regulators, past heads of major energy companies, leading economists, academics and international energy experts. Judging focused on commercially applied innovation and criteria included commercial availability, financial results, innovation, net job growth and being technologically proven.

In recent years there’s been a terrific increase in the amount of solar panels being installed on the roofs on homes across the UK. With numerous desirable fiscal benefits and the apparent benefits to the natural environment the prospect of a solar panel installation has ensured there exists a great amount of interest of an increasingly large amount of people.
Despite the interest, most people are reluctant about taking any further steps into checking out the possibility of getting a solar panel installation on their rooftops. One of the main reasons for trepidation is concern in relation to whether their roof is capable of taking the panels, whether they need planning permission, and whether their roof is positioned to get the most of the suns energy! this article studies a few of the principal concerns people have and provides a brief explanation into the concrete realities associated with the issues in an attempt to allay their concerns.
Can my roof top accommodate solar panels?
The most prevalent concern prospective consumers often have when it comes to solar panel installations is whether their roof will physically accommodate the solar panels. Generally speaking, most roofs should be able to support the panels since they are not especially weighty plus the weight is distributed over a significant surface area. If you’re in doubt then a survey might be wise to be sure the roof is capable of carrying the weight. before you worry about the potential cost of this kind of survey, it will generally be the case that if you ask for a quote from a respected solar panel installation company they will give you a survey for you free of charge. They’ll then be able to tell you either whether there are no problems, or that some remedial or support work has to be carried out. in many cases the company should be able to organise this for you hassle free, and could be included on the overall quote. Remember, the possible financial advantages of a solar panel installation at this moment in time can amount to about ?1700 a year. Spending a few hundred pounds in an one of transaction to reinforce the roof still means that you will overall receive a great return on investment.
Is my roof capable of making the most out of the suns energy?
Another issue many people have is whether or not their solar panel installation would generate enough energy. The most frequent myth is that only south facing rooftops can have solar panels. The truth is, many roofs which are not totally south facing can also take full advantage of the suns energy and produce solar electricity. The main problem in reality is whether there is anything shading the roof. The most common offender is large trees and chimneys which would decrease the amount of direct light that could hit the panels. Anything limiting how much light will reduce the efficiency of the panels, because the panels transform light energy into electricity.
Do I require planning permission for a solar panel installation?
With officious planning committees along with a seemingly indefinite quantity of busy bodies all too pleased to obstruct planning permission applications it truly is with welcome relief that i can tell you that most domestic solar panel installations don’t require planning approval. things to be aware of include if your property or home is listed or in a conservation area. in these circumstances then planning permission may be required. To find out whether your property comes within these categories you can try a local searches check, though almost all of you will already have a definite idea because this would have been revealed when you bought the house. For larger industrial solar panels installations it is also very likely that planning permission will be necessary.
The article author works directly with respected solar panel installation company Solar Days, who supply quality solar panels and who are very happy to help with roof top surveys and repair work.

on December 8th, 2011% THE Feed-In Tariff, in which people get paid for the electricity they generate from, for instance, solar panels, is a good thing.
R J Bray (Mailbag, December 3) takes me to task for my dismay over the government cuts to the funding of the tariff for solar panels and in particular the suspending of the Kirklees Council scheme to install solar panels on the homes of 1,000 council tenants.
He asks whether my statement means that there are only 1,000 people in the Huddersfield area living in fuel poverty and all are currently living in council property.
no it doesn’t, but it would be a start to help those people by running such a scheme which could then be expanded later.
There are also currently schemes available for private householders where the panels are installed for free and the householders get the benefit of the electricity in return for handing the Feed-In Tariff to the installing company.
A number of households around Huddersfield have done this already. If he wants details I’ll pass them on to him.
of course not everyone can benefit from this scheme due to the orientation or size of their roof, but many can.
so the existing policy framework for solar is one of which many people can take advantage, but changes by the Government threaten its viability for everyone.
Mr Bray says that Feed-In Tariffs ‘help create higher energy bills for people by having them fund through their meters the Feed-In Tariffs for those who have solar panels or wind turbines’.
the actual impact of the Feed-In Tariff policy on energy bills last year was 30p for the average household. This is less than a penny a week. the cost of a new nuclear power station, which Mr Bray is so keen on, can be about pounds 4.25bn.
that doesn’t take into account the decommissioning costs and the costly handling of dangerous nuclear waste. This will have a much more significant impact on energy bills.
He asks why I and Clr Khan don’t campaign for cheaper energy for everyone.
I don’t presume to speak for Clr Khan but for my part I successfully proposed making insulation free for all householders in Kirklees, I was the trustee of a national fuel poverty charity for eight years and have helped many householders reduce their fuel bills through advice on energy tariffs and by getting information out to householders on a number of ways to help reduce fuel bills.
so I don’t believe I’m deficient in wanting to help people reduce their bills.
Mr Bray adds: ‘Industry along with our homes cannot be sustained by wind, solar or wave power.’ I agree to a point. in addition we are going to need greater levels of energy efficiency in buildings, better controls and energy management, district heating systems, anaerobic digestion and a whole host of other actions to make the future of energy supply in the UK more secure.
This does rather beg a question why only Malta and Luxembourg in Europe have a worse proportion of their energy generated from renewable sources than the UK.
what is technically possible on the Continent seems somehow difficult here. the laws of physics are not different this side of the Channel but some attitudes, prejudices and opinions certainly are.

SAN JOSE, Calif. and LAUSANNE, Switzerland, Dec. 7, 2011 /PRNewswire/ — SunPower Corp. (NASDAQ: SPWR), a Silicon Valley manufacturer of high-efficiency solar cells, solar panels and solar systems, today announced that the company is providing solar cells to the Solar Impulse project. The Solar Impulse team has produced a prototype (HB-SIA) solar airplane that, for the first time in aviation history, succeeded in flying for 26 consecutive hours powered only by solar energy. a second solar airplane (HB-SIB) is currently under construction with plans to circumnavigate the globe in 2014. Both planes are powered by SunPower’s high-efficiency solar cells.
SunPower’s Maxeon™ solar cell technology was selected because of its industry-leading efficiency and thickness of its solar cell, an average of only 135 microns, which is important for the power to weight ratio of the aircraft. After the success of the first solar plane, a second airplane is under construction using approximately 22,000 of the SunPower solar cells. The cells will be incorporated into the plane’s wings and horizontal stabilizer, with each cell producing an efficiency of approximately 22.7 percent. The solar cells will power the electrical engines, storing the excess solar energy for the night flying in lithium batteries.
“SunPower is pleased to be involved with such an ambitious project as the Solar Impulse airplane as it prepares for its record-setting, around-the-world flight,” said Tom Werner, SunPower president and CEO. “As a vertically integrated company, SunPower not only powers distinctive projects such as Solar Impulse, but our high-efficiency, high-reliability solar panels are chosen by residential, commercial and utility-scale power plant customers worldwide. We are confident that our experience in developing our industry-leading technology with guaranteed performance will help the Solar Impulse airplane to successfully achieve its goal to circumnavigate the globe.”
The successful day and night solar flight achieved in July 2010 brought the initial phase of the Solar Impulse adventure launched by Bertrand Piccard and Andre Borschberg to a successful conclusion, validating their goal of demonstrating the enormous potential of new technologies for saving energy and renewable forms of energy. The lessons learned from this first prototype are now being incorporated into the development of a second airplane, HB-SIB, which will attempt to fly round the world starting in 2014.
“We are pleased to partner with SunPower, a leader in designing and delivering high-efficiency solar technologies. SunPower’s solar cells are optimum for this project, as they offer the performance and low-weight that is needed for our revolutionary solar airplanes,” said Andre Borschberg, Solar Impulse co-founder and CEO.
“A pioneer in its field, SunPower represents the kind of partner we like to collaborate with to not only power the world’s first manned solar aircraft, but to also spread our message on the benefits of renewable energy,” added Bertrand Piccard, Solar Impulse initiator and chairman.
SunPower has a legacy of powering unique solar projects. in 1993, SunPower’s high-efficiency solar cells drove the Honda car to win the World Solar Challenge from Darwin to Adelaide in Australia a full day ahead of the second place finisher. The company also worked with NASA to develop the unmanned Helios solar plane that flew to a record altitude of 96,863 feet, also powered by SunPower high-efficiency solar cells. most recently, SunPower partnered with Planet Solar to power the world’s largest solar catamaran that is currently on an around-the-world tour, arriving at most destinations ahead of schedule, weather permitting. since 2005, SunPower has supported university students with high-efficiency SunPower solar systems for their solar home entries in the U.S. Department of Energy Solar Decathlon. And in 2009, the company also supported students with their entries in the first Solar Decathlon Europe.

The main function of roof solar panels is to convert the sun’s energy into usable electrical power for your home or office. these panels or modules are mounted on a steel frame and positioned on the top of your roof. Power produced by solar modules or panels is converted from Direct Current (DC) to Alternating Current (AC) through the use of an inverter. AC current is the usable electrical power that we need to bring power to our homes and businesses.
There are several kinds of roof solar panels on the market. They vary in efficiency, price and size. with more efficient roof solar panels, it is possible to generate the same amount of power with fewer panels than less efficient panels, taking up less space and possibly lowering costs.
All solar modules or panels are built from solar cells. There are a number of ways to make solar cells and each has its own benefits. There are three types of cells that make roof solar panels.
1. Monocrystalline - these are solar cells that are created from a single crystal. these cells are sliced from a silicon boule that is grown from a single crystal, or a crystal that has grown in one direction. these types of roof solar panels are more efficient in their ability to absorb the energy from the sun and convert it electricity. They are more expensive to manufacture as well. these panels can be made into smaller panels but with the same wattage as other types of cells.
One thing to keep in mind when looking into solar modules: 100 watts of power from monocrystalline cells, is the same as 100 watts of power from any other type of cell whether it be polycrystalline or amorphous.
2. Polycrystalline - these are solar cells that are created from multifaceted crystalline also known as mulitcrystalline. these cells are sliced from a silicon boule that is grown from a multifaceted crystalline product or a crystal that has grown in different directions. Polycrystalline roof solar panels are less efficient thus needing to make larger cells for the same wattage as the monocrystalline panels. with the development of silicon nitride multicrystalline however, they are now as efficient as the monocrystalline solar panels with similar sized monocrystalline cells.
3. Amorphous - these are panels made from thin film technology where molten silicon is spread across plates of stainless steel or other material. these are lower in efficiency and require a significantly larger panel to equal the wattage of both the monocrystalline and polycrystalline cell panels. I wouldn’t dismiss this technology however, because these cells have been very successfully engineered as flexible solar panels for the outdoor adventurer. They have been used to power items such as cell phones, walkie talkies and ipods. these are also manufactured inside of backpacks and athletic clothing and jackets.
When looking into solar modules and panels, remember to keep in mind that 100 watts of power from monocrystalline cells, is the same as 100 watts of power from any other type of cell whether it be polycrystalline or amorphous.

The type of roof solar panel you need is determined by the application for which you want to use it. There are generally two different types. One uses photovoltaic cells for producing electricity that is sent into your home’s electrical system and keeps you from buying some or all of your electricity from the power supplier while the other one uses tubing with water running through the tubes. The tubes are generally painted flat black for the sun’s maximum heat absorption which warms the water which is sent into your home, usually to the hot water heater. this causes the hot water heater to run much less than it ordinarily would. Both of these two types of roof solar panels can save you on your energy bills, but the one that we will focus on in this article is the photovoltaic cell roof solar panel.
If you want to produce electricity, you need to use a photovoltaic cell roof solar panel. as already stated, this type of panel uses photovoltaic cells as its main components. these cells are connected together and mounted on a base of some type and then sealed in by sidewalls and a glass or plexi glass top. this makes up the panel that will produce electricity by turning the sun’s rays into electricity by the photovoltaic cells. Cold or heat has no effect as to how much electricity can be produce by a roof solar panel. The amount of electricity that is produced is determined by the amount of sunlight and the number of photovoltaic cells that are in the roof solar panel and also by the number of panels used. You can produce electricity for part or all of your home or for an out building. how much electricity production you might want will be up to you.
In cold weather climates where there is snowfall, you will want to place the roof solar panels in a place where you can get to them to remove accumulated snow in order that the sun’s rays on the photovoltaic cells can do its job. You will need to place the roof solar panels on a south facing roof or wall. They can also be placed on a structure built solely for their use. If you did build a separate structure for this purpose you might want to build it where as you can tilt the panels to gather maximum sunlight according to the season. So as you can see, a roof solar panel can be placed on a roof or even a separate structure.
