Solar energy plays a pivotal role in creating clean energy with the help of solar panels. Solar panels are most frequently installed on rooftops. Before installation, it is necessary to analyze which is the best roof for solar panels.
Solar energy helps in fighting against the present global climatic plight. Solar panels (or ‘PV’ panels) are an accumulation of solar cells or photovoltaic cells. Each solar cell can produce 0.5 volts of electricity.
Solar panels can be acquired from sun energy companies or even from online stores. Solar panels should be located where it gets maximum sun exposure. Hence, the rooftop can be considered an ideal location.
The most important factor first to be taken into consideration is the best roof for solar panels installation.
Best Roof for Solar Panels Review And Buying Guide
Why roof is popular for solar panel installation?
People are showing a positive attitude towards installing residential solar systems because of their beneficial effects on the environment. For solar panels, installation roof location is more preferred over ground or yard because of space factor.
Most of houses do not have the needed space in their yard for solar panels system. So roof has become a more well-liked option. Therefore, it is better to explore the best roof for solar panel before installation.
Roof requirements for solar panels:
A roof is more likely to be chosen for the home solar system. It is essential to analyze every detail that helps to pick the best roof for solar panel.
Before installation, following roof requirements for solar panels should be given a check:
Presently solar panel roof installation has become quite popular. But before installation, it is essential to scrutinize the condition of the roof.
It is better to consult experts if the roof is old and in a weak state. Then it is better to replace the roof before installing solar panels.
If solar panels are installed without examining the roof; you may have to bear heavy expenditure. Uninstalling the solar panels, dismantling and repairing the roof, and again reinstalling the solar panels will cost a hefty amount.
Solar panels come with a warranty of 25-30 years of service. So if the roof is new or updated before installation then one will enjoy the service till the mentioned time span.
Roof Angle or Roof Pitch:
Best roof angle or best roof pitch for solar panels plays a key role in providing solar panel efficiency. The ideal roof angle or pitch to acquire maximum solar energy is 30 degrees.
But the solar panels also work efficiently on flatter or steeper roofs.
The optimal rooftop angle is a 30-degree angle. But for a roof tilt at 40-degree will provide sufficient heat energy output.
Again a tilt beyond 40-degree will be a lot steeper for the solar panels to produce a good amount of clean electricity.
Unlike, slope roofs, flat roofs do not require any kind of drilling to hold up tightly. In flat roofs, angle bars are used to tilt the solar panels at 30 degrees.
It is always advisable to examine the roof strength of the experts. It is to understand how much weight roofs can withstand as solar panels have their own weight.
If a roof is not strong enough to hold the weight of solar panels, it is likely to collapse leading to a huge loss. So an investigation of roof strength can avoid any type of collapsible situation. Also, apply for extra support if required.
The direction of Solar Panels for Roof or Roof Orientation:
The direction of solar panels is determined by the hemispheric location. In the Northern Hemisphere, solar panels should face the south (southeast or southwest) direction. In the Southern Hemisphere, solar panels should face the north (northeast or northwest) direction.
Ideally, the appropriate direction for a solar panel is south.
Southeast and southwest directions may produce a little less electricity, but the power will be sufficient for residential loads.
Space Requirement for Roof:
Calculating space requirements for roof solar panel installation can be a bit complicated. It is due to the factors such as the size of the house, type, and size of solar panels, and the electricity consumed on a monthly ( or daily basis).
On average small houses require almost 200 square feet of roof space. Large houses require almost 1000 square feet of roof space for clean energy usage.
Normally one should have 500-600 square feet of roof area for solar panel installation to enjoy sufficient power at home.
Whether Solar Panels are Good for Roofs or not?
A common question frequently comes to mind is whether solar panels are good or bad for roofs? The answer is that solar panels are absolutely good for roofs.
Solar panels protect the roof from the harmful UV rays of the sun. Otherwise, the roof will absorb the rays which will gradually lead to damage.
The solar panels give shade to the roof which helps in keeping the temperature lower inside the house. Further solar panels also protect the roof from snow, rain, and hail.
But it is to be considered that the installation needs drilling of large holes on the roof for securing the solar system with the help of lag bolts.
Therefore, consulting a professional may help in avoiding water leakage and infrastructural damage to the house.
Solar panels are compatible with various roof materials. But the best roof material for solar panels is composite roofing, also known as asphalt shingles. Asphalt shingle roof is perhaps the most suitable and compatible roof material for solar panel installation.
Apart from composite roofing, other compatible materials like tile roofs and standing seam metal roofs can easily withstand solar panels installation. Rather it is very easy to install on these roof materials.
In fact, metal roofing does not need drilling. Rather a metal roof with a standing seam is one of the best flat roof material for solar panels.
Talking about non-compatible and unsuitable roof materials for solar panels are wood roofing, clay roofing, slate roofing and terra cotta tile roofing. These roof materials are weak, brittle, and easily breakable.
Installers usually find it difficult to work, and so they avoid installations on such roof materials. Even if installer agrees to install, it can cost huge money.
Roof Surrounding (shade):
An ideal roof is the one where the solar panels get maximum sun exposure and less of shade. Shade around the roof is an important factor that determines how efficiently solar panels will work.
If a house is surrounded by trees, then professional installers will come out with an appropriate solution such as trimming the brunches. Then the roof will get direct sun ray.
If the house is surrounded by buildings, there is hardly anything that could be done. There is no point installing solar system if sufficient sunlight is not available.
Roof’s Reflectivity Rating:
Before solar panels can be installed, definitely get your roof’s reflectivity rated examined by professional. Roof’s reflectivity rating is a measurement of how much say ray is reflected by the roof.
Roof with over 65% of reflectivity rating is a great reflector of sun’s ray which keeps your home cooler during summers. Lighter colour roofs are more efficient for higher reflectivity rating.
Roof types for solar panels:
Do you want to install solar panels on a rooftop? Then you should have sound knowledge about solar type roof design. Also how efficiently these roofs work to produce clean energy.
Basically, solar panels work on every roof types. But the power sufficiency may vary. Following are the details of different types of roof for solar panels:
Composite Roofing or Asphalt Shingle Roofs:
The most popular roof type is composite roofing, also known as asphalt shingles. These roofing shingles are composed of cellulose mat or fibregrass.
These materials make the asphalt shingles roofs flexible, durable and cost-effective. Mostly, people prefer composite roofing for solar panels.
It is very simple to install solar panels on asphalt shingle roofs. Installers drill studs in the roof to attach mounts. Then the gap between the panel and the studs are closed with flashings. It is to avoid water leakage inside the house.
The second most commonly preferred roof type is tiled roof. Tile roofing can be both expensive and cheap depending upon the material used in making the tiles.
Solar panels installation on clay tile roof may cost heavy on the pocket part, whereas, concrete tile roof may be of lesser cost.
The solar panels are installed on the tile roof with the help of brackets, which uplift the panels from the roof. The measurement of the gap between panels and roof depends upon the material with which the tiles are made.
Metal roofing with standing seam is most cost-effective and favorable of all the roof types. The best part of metal roofing is that there is no need of drilling in the roof.
The metal standing seam makes the whole installation process extremely simple and feasible.
Gravel and Tar Roofing:
Gravel and tar roofing is one of the best flat roof material for solar panels. This roof type is composed of layers of sheets fixed with materials like hot tar and roofing felt.
Being flat roof, additional brackets has to be attached to tilt the panel at 30-degree angle. Installation on such roof can be expensive compared to tilted roof.
Although wooden roofs looks elegant but it is quite disapproving for solar panel installation. Woods are easily breakable because brittle and delicate texture.
Wood roofing is a fire hazard for solar panels so it can lead to involvement of authorities. In such cases, re-roofing might be an option or mounting the solar panel on the ground if space is available.
Flat roofing is an easy option to go for because it is more flexible compared to angled roofs. It is common in taller buildings.
Solar panels need very less drillings in flat roofing. Again you may also attach bracket to tilt the angle of the panel to get maximum sun rays.
Flat roofing may come in a low-angle structure, known as Torch-Down roof. It can be expensive due to its durable quality.
Foam roofing is the most light weight roof among all roof types. Its easy installation makes it installer’s favourite. Foam roofing is durable and waterproof.
During winter foam roof restore heat and keeps the house warm from inside. SPF-foam roofing is completely environment friendly.
What color roof is best for solar panels?
Roof color is important to determine solar power efficiency. Generally lighter color roofs are more energy efficient than darker color. Light color absorbs less heat and dark color absorbs more heat.
A light color roof deflects sun rays and keeps the home cooler during summers. But again during winter it can make the rooms cold.
White, off-white colour roofs are generally called ‘cool roofs’. White roof is also regarded the best color roof for solar panels.
A dark colour roof deflects less sun rays and keeps the home warm during winters. But in summers it can be discomforting inside the house unless you have air-conditioner. Black, dark-blue, red colour roofs are generally called ‘warm roofs’.
In fact, lighter colors are capable of reflecting 55% to 90% of sun rays, whereas, dark colors can reflect only 5 to 20% of sun rays.
All About Best Metal Roof For Solar Panel:
Metal roofing along with standing seam is the most low-budget and hustle free roof type for installing solar power system. Other roof types require drilling holes in the roof but in the case of metal roofing.
Metal roofing is extremely durable. It supports the weight of the solar panel which further prevents roof damaging.
Metal roofing is eco-friendly in nature because it is composed of recycled materials.
Unlike other roof types metal roofing can be long lasting, up to a life span of almost 60years. It means it can easily outlast the life span of solar panels.
Do metal roofs make house hotter?
No metal roofs does not make house hotter. Metal roofs are considered ‘cool roofs’ due to its higher reflectivity rating.
It provides lower temperature inside the house making it pleasant during summer months. Other roof types fail to do so.
It can withstand heavy weight. So both types of solar panels, crystalline solar panels and thin-film PV solar laminates can be easily installed on metal roofs.
Before installing roof solar system, it is better to look into the best types of metal roofing –
- Exposed fastener metal roofing: It is also called ‘screw down’ metal roofing. In this type, screws are placed through the metal roofs to attach it to the roof structure below.
- Metal shingle roofing: This type of metal roofing gives a traditional shingle look.
- Metal roofing with standing seam: It uses hidden fasteners under metal roofing material seams to attach it to the roof structure below. It does not need any drilling on roof.
So metal roof with standing seam is the reply to the commonly asked question by public-what type of metal roof is best for solar?
What color metal roof is best for solar panels?
Choosing the correct color metal roof for solar panels installation can be beneficial for you. It is because the right color metal roof can increase the energy efficiency level of the solar panels.
Lighter color like beige, tan, white, light grey can reflect sunlight more and can save extra energy.
Is a flat roof better for solar panels?
Solar system in flat roof is commonly found in high rising commercial buildings. It can easily be installed in residential household as well. Installing solar panels on flat roof is more feasible than on slopped roof.
Solar installing process and maintenance are easily assessable on flat roofing. On flat roof solar panel visibility is less from the ground level.
Solar panels can be mounted at a preferable pitch (usually 30 or 40-degrees) on flat roofing for maximum sun exposure.
During monsoon, rain water easily washes away all dirt and wastes that are deposited solar panels when mounted on a preferred angle.
Flat roof solar panel can be damaged by strong winds. This is prevented by attaching the panels to the roof structure. Weighted mounting system is common on flat roofs.
Flat roof PV panels do not necessarily need any planning permission. The guidelines are same as that of pitched roofs. But it will be wise for you to consult the local planning authority of your area.
Apart from solar panel, you can also install solar thermal system on flat roofs. The process is similar to P.V system. Solar thermal system keeps your house warm during shivering winters.
Installing PV panels on flat roofs can be budget-friendly. You can simply shrink your carbon footprint production.
It also reduces your electricity bill. So installing solar panels on flat roof is a good option.
Different Types of Solar Panels for Roof:
Solar panels come in variety. They all differ in terms of installation cost, solar efficiency, working capabilities. So before buy solar panel you should have sound knowledge regarding the types.
The different types of solar panels that can be installed in the roof are:
Solar Roof Shingles:
Presently solar roof shingles are on the trend. It looks exactly like the traditional asphalt shingles. It gives a modern and elegant look to the house.
Solar shingles are sturdy and effective. It protects the roof from damage.
Each shingle is capable of producing 13-67 watts of solar electricity. Its resistant quality can withstand any weather condition.
But the installation is not cost-effective unlike traditional asphalt shingles.
Polycrystalline Solar Panels:
Solar panels are made of solar cells and each residential solar panel contains around 40 solar cells. Two main solar panels are polycrystalline and monocrystalline.
Polycrystalline are the very first developed solar panels. Polycrystalline panels are rectangular shaped.
Melted silicon is poured into a rectangle which gives the shape. It cannot create sufficient electricity from heat energy.
Monocrystalline Solar Panels:
Monocrystalline solar panels are more heat-resistant compared to polycrystalline panels. It is highly efficient as it is composed of pure silicon.
It is cylindrical in shape.
It is capable of producing more electricity. So it makes the requirement is less in number.
Monocrystalline panel are very costly to buy. But they come with a long-lasting feature.
Thin Film Solar Panel:
Thin film solar panels are very new in solar panel industry. It is very less in use in residential arenas.
It is made by layering various semi-conducting materials like silicon, cadium telluride, and copper indium gallium selenide and rolled out.
Installing thin film solar panel requires a lot of space. Also it comes with shorter warranty as it tends to get damage early. It is less energy-efficient in nature.
Thin film solar panels are less expensive and more flexible compared to crystalline solar panels.
These are manufactured in factories into shingles. These can come in black or blue in colour after manufacturing.
Components of Solar Power System:
Before setting up solar power system, you should know about different components it has.
It is composed of solar or PV panels, inverter, and a mount. The solar inverter comes with computerised controller.
Using sun rays, solar panels create ‘Direct Current’ (D.C) and the solar inverter converts it into ‘Alternative Current’ (A.C). (A.C and D.C are two ways in which electric energy flow).
After the conversion, the power is ready for household use. The system also comes with a batter back, if needed.
The controller monitors the solar power system to work effectively.
Solar Panel Installation Process:
Solar system is installed on residential and commercial rooftops to get maximum sun exposure. Solar panels installation process involves a number of steps:
Step-1: Scaffolding Setting Up:
You need set up scaffoldings in order take certain protective measure during the installation process in the rooftop.
Step-2: Installation of Solar Panel Mounts:
Mounting system is set up on the rooftop to support the base of PV panels. Direction is to be chalked out before installing the panel.
For the locations in Northern and Southern Hemisphere, the panel direction should be south and north respectively.
Mounts should be tiled at an angle of 18 -36 degrees to get sufficient solar energy.
Solar panels mount come in three varieties with which you can install the panels on the rooftop. These mounts are-
· Pole mounts,
· Roof-ground mounts,
· Flush mounts.
Step-3: Install the Solar Panels:
Once the mounting structure is set up, solar panels are installed on it. PV panels are then screwed up tightly with nuts and bolts on the mount for a sturdy and long lasting hold.
Step-4: Wire the Solar Panels:
Electrical wiring is next step in the installation process. MC4 connector is used in wiring. MC4 connector is a universal connector which can connect with different type of solar panels.
During this process the home electricity should be shut off. The solar panels are electrically connected to one another in two following ways:
· Series Connection – here the Positive (+) wire is joined with negative (-) wire to increase the voltage match with the battery bank.
· Parallel Connection- here Positive (+) wire is joined with Positive (+) wire and Negative (-) wire is joined with Negative (-) wire. In this wiring the voltage of each panel remains the same.
Step-5: Set Up Solar Inverter:
Now set up the solar inverter by connecting it to the system. The solar inverter can be places both outdoor and indoor.
But indoor is more preferable as inverters work efficiently in cooler places. If placed outdoor, make sure to keep away from sun heat.
Step-6: Bond Solar Inverter and Solar Battery:
Next the solar inverter is connected to the solar panels with the support of wiring.
The Positive (+) wires of the panel and inverter is connected together. Similarly, the Negative (-) wires of the panel and inverter is also connected together.
Step-7: Connecting the Inverter to the Consumer Unit:
Electricity will be produced only when the solar inverter is connected to the consumer unit. Now a meter is connected to check the amount of electricity produced by the panels.
Step-8: Finally Start the Solar Panels:
The final step is to switch on the main power. Test the solar panels; how much clean electricity is being generated from the panel.
Thus the solar system installation is completed.
Where should Solar Panels be Installed?
Solar panels work efficiently when it receives maximum sun energy. So solar panel is located in open areas like rooftop, tall buildings, yard or ground.
It is advisable to place solar panels under the place which receives direct afternoon sunlight.
Check into the obstacles that may stop the Photovoltaic panels from receiving direct sunlight. The PV panels won’t be able to generate sufficient electricity. So try to prevent the obstacles. For example trim the brunches of the trees that guards the sun.
Make sure to place panels in such position that no shadow is able to guard the panel. Solar power system operates dynamically when exposed to direct solar energy.
How to Maintain Solar Panels:
Setting up solar power system at your house is the best way to get clean electricity. It is eco-friendly as well.
Solar panels may be expensive but long warranty of 25-30years is a good ‘Return on Investment’ (‘R.O.I’).
Your work is not over once you have installed solar panels. Rather it is very important to maintain the panels for it to work adequately.
Maintenance of solar panels makes sure of ample generation of clean energy.
The most important and common maintenance is keeping the panels clean. Harsh weather conditions like storms, hail or heavy rainfall may lead to accumulation of debris, dust, and dirt on the panels. Periodic cleaning will keep the panels working effectively.
Another type of maintenance is annual inspection. You should yearly call for a professional installer to examine how efficiently the entire solar system is working.
Apart from annual inspection, if any problem arises with the solar panels, it better to call for an immediate inspection. For example, problems like solar panels not generating sufficient electricity, is alarming. Quickly fix a maintenance appointment.
Another option for maintenance is self-cleaning. You can simply use a garden hose to clean the surface of the panels. You can also use soap waters to scrub the panels if deep cleaning is needed.
Do not apply water to wash when the panels are hot. Better to wash it in early morning or evening.
If you are not comfortable with self-cleaning; definitely call washing service company for cleaning.
Also it is advisable to consult professionals before proceeding with self-cleaning.
Discuss about the warrant condition with your installer. It is because certain manufacturers may not favour self-cleaning, and close warranty.
