Instructions for Installing Solar Panels on Roofs – Here are the pro tips when mounting solar panel systems on shingle roofs: Step 1: Lay out the installation materials you need. Make sure that all the materials necessary for installation are nearby. You surely wouldn’t want to go from the roof and back repeatedly.
- Step 2: Determine where the stanchions go.
- Decide where the stanchions go.
- These refer to the large screws that keep the solar panels in place.
- When mounted, they should be solid enough and can withstand tearing the panels from your roof (upforce).
- Find the roof rafters with the aid of a stud finder or your home’s blueprint.
These will help you figure out the correct placement of the stanchions. Position the stanchions at least 4 feet apart.
Step 3: Fasten the screws to the roof. When fastening the screws to the roof, utilize a drill to create holes in the rafters. Step 4: Tightly put the screws in the holes and secure them.
It would help if you tightly secured the lower and upper aluminum rails to the stanchions. Utilize bolts to do this. Since optimal tightness is required, utilize an impact driver to achieve this. Afterward, make sure that you seal the screws tightly to maintain the thermal envelope of your home.
- Substantially, thermoseal roofing is the most excellent way to execute this.
- This approach will help keep an incredibly tight lock on your roof and prevent any elements from getting inside.
- Leakage is less likely to emerge if the stanchions are correctly installed.
- Step 5: Gauge the distance from the rails.
Gauge the distance from the rails when installing solar panels. Put a measuring tape diagonally from the top of one rail to the bottom of the rail situated directly across from it. Repeat the process on the other side. The measurements should be equal. If they are, the rails are parallel to each other.
On the other hand, you’ll need to make some adjustments if the measurements aren’t equal. Step 6: Install the middle rail. The next step will be to set up the center rail. Note that the center rail must be aligned with the lower and upper rails. Step 7: Bring power to the solar panels. Bringing power to entails putting wires into them and running them to the power inverter kit to make up your conductor system.
Then, install the power inverter kit below each of your panels. Set up some 6-gauge copper grounding wire into the inverters. This process will create your conductor system. Link the wire connections from one solar array to the other. Step 8: Position the panels on top of the previously installed stanchions.
- Finally, place the panels above the previously installed stanchions.
- Link the plug connections.
- It is also essential to screw the securing clips onto the rails to ensure that the panels are solid as a rock.
- You will need to deal with more electrical work after all these.
- Start extending some wires from the panels and link them to an electrical meter.
You’ll also need to link the wires to an electrical sub-panel.

Can solar panels be installed DIY?
Solar installations are getting easier all the time and there’s plenty of do-it-yourself information out there. But are you ready to go the DIY route? – Photo © Heshphoto, inc., excerpted from Install Your Own Solar Panels, If you’re interested in solar power, surely you already know that solar electricity is good for the environment, national security, and the air we breathe, not to mention your electricity bill.
And that it’s one of the best ways to reduce your household’s contribution to global warming. You’ve also probably heard that going solar can actually be cheaper than paying for utility power, and you might wonder whether this claim is true. Well, in most cases, it is true. It just takes time for the incremental savings to overtake the initial investment (after that, the solar power is free).
If you install the solar system yourself, you can hit this tipping point a lot sooner — in some cases, in half the time. That brings us to the next big question: Can you really install your own solar panels? Again, the answer is yes. If you can drive lag bolts and assemble prefabricated parts, and if you’re willing to spend a day or two on your roof (or not, if you’re mounting your panels on the ground), you can install your own solar system.
You don’t have to know how to hook up the solar panels to your household electricity or the utility grid. You’ll hire an electrician for the house hookup, and the utility company will take care of the rest, usually for free. For a completely off-grid system, the utility company isn’t involved at all. Perhaps disappointingly, this job isn’t even a good excuse to buy new power tools, since the only one you need is a good drill.
So, if this is such a doable project, why do most people use professional installers? For starters, a lot of people have good reasons to hire out virtually everything, from oil changes to grocery shopping. (That’s probably not you, but even if it is, our book can help you plan for a solar installation and find a good local installer.) Solar professionals handle more than the installation.
- They design the system, they apply for rebates and credits, they order all the necessary parts, and they obtain the permits and pass all the inspections.
- But the fact is, you can do all of these things yourself, provided you have a helpful adviser and you are willing to follow the rules of the local building authority (that’s where you’ll get those permits).
Solar installations are getting easier all the time, and you might be surprised at how much do-it-yourself (DIY) help is available. Two good examples are PVWatts and the Database of State Incentives for Renewables & Efficiency (DSIRE), PVWatts is an online calculator that helps you size a solar-electric system based on the location and position of your house and the angle of your roof.
Solar pros use the same simple tool, but it’s free for everyone. DSIRE offers an up-to-date, comprehensive listing of renewable energy rebates, tax breaks, and other financial incentives available in any area of the United States. And it’s also free and easy to use. Those two resources alone help answer the two most common questions homeowners have about solar electricity: How big of a system do I need? and How much will it cost? Other resources include solar equipment suppliers that cater to DIYers and offer purchasing and technical support, as well as online communities like Build It Solar,
And there’s no law that says DIYers can’t hire a solar professional for help with specific aspects of their project, such as creating design specifications, choosing equipment, or preparing permit documents. We should also say up front that installing your own solar panels is not a process well-served by cutting corners.
- We don’t want you to install your system without a permit or without hiring an electrician to make the final hookups.
- Even professional solar installers use electricians for this stuff.) The permit process can be a pain, yes, but it’s there to ensure that your system is safe, not just for you but also for emergency responders who might need to work around your mini power plant.
When you work with the local building department you also learn about critical design factors, such as wind and snow loads, that are specific to your area. Photo © Heshphoto, inc., excerpted from Install Your Own Solar Panels,
Can I buy my own solar system?
Contact KC Green Energy for Solar Panel Installation – Can you buy and install your own solar panels? Yes. Should you? No. Ultimately, you may end up paying more money and wasting a lot of time if you try to install solar panels yourself. Instead, leave it up to the experts.
Can I have solar without connecting to the grid?
Stand alone solar power – A stand alone solar system the solar panels are not connected to a grid but instead are used to charge a bank of batteries. These batteries store the power produced by the solar panels and then your electrical loads draw their electricity from these batteries.
Stand alone solar power systems have been used for a long time in areas where no public grid is available. However, the real growth in solar power systems in the last 5 years has been in grid connect systems. Why is this? Because most people live in areas that are connected to a public grid and stand-alone systems are much, much more expensive than grid connect systems because batteries are very expensive.
It is my hope that in the future we will see a fall in battery prices and that stand alone systems will be used more. However, batteries will need to become a lot cheaper for this to happen. A grid connect system is one that works in with the local utility grid so that when your solar panels produce more solar electricity than your house is using the surplus power is fed into the grid. With a grid connect solar power system when your house requires more power than what your solar panels are producing then the balance of your electricity is supplied by the utility grid.
So for example if your electrical loads in your house were consuming 20 amps of power and your solar power was only generating 12 amps then you would be drawing 8 amps from the grid. Obviously at night all of your electrical needs are supplied by the grid because with a grid connect system you do not store the power you generate during the day.
With a stand alone solar system the solar panels are not connected to a grid but instead are used to charge a bank of batteries. These batteries store the power produced by the solar panels and then your electrical loads draw their electricity from these batteries.

Their most popular cheap model is the Solarland SLP020-24U Silver Poly 24 Volt Solar Panel, which is typically used for powering traffic lights and other small off-grid uses. Certain features, like its efficiency rating, are either non-existent or challenging to find, which makes this cheap panel a potentially risky purchase.
How long does it take for solar panels to pay for themselves?
What is a Good Solar Payback Period? – The most common estimate of the average payback period for solar panels is six to ten years, This is a pretty wide range because there are many factors that will influence the number of years it can take to pay off your panels and the monthly savings you can expect.
- For example, a larger solar installation is going to have a higher upfront cost, but higher monthly savings.
- And if the electricity rate from your utility goes up significantly, that can have a large impact on your long-term savings as well.
- Modern photovoltaic (PV) solar panels should last at least twenty-five years, with at least 80% efficiency at the end of that period.
Some new models of solar panels can last even longer than that. So, if your payback period is ten years, you are still looking at around fifteen years of additional savings on your electrical costs.
How much would it cost to install your own solar panels?
3. Estimate and compare the cost of solar panels for homes – The brunt of the expense with solar panels is in installation and the purchase of the actual panels. Minimal long-term costs can make up for the upfront costs. “Most systems don’t require much maintenance and are designed to last for 20 years or more with little change to the amount of electricity produced,” Nilsen says.
When calculating the total price, consider how much energy you regularly consume — your usage is listed on your monthly utility bill — and what size system will generate the amount needed. Some tools, like the SolarReviews calculator, estimate the system size for you. With installation, an average residential 5-kW system costs from $3 to $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range.
That cost is before any tax credits or incentives. If you know your current energy usage, you can calculate how much you’ll need to pay for solar panels. Then comparison shop for solar panels as you would other big-ticket items, such as a car or TV, says Vikram Aggarwal, CEO of the solar marketplace EnergySage.
Is solar cheaper than electric?
How Does Solar Energy Compare When it Comes to Cost? – If you’re looking to save money with solar panels, it depends on a few key factors such as how much sunshine you get, local electricity rates and the size of your pool or home. Although solar energy requires an initial investment to purchase and set up, people find that solar energy is a lot less expensive than electric power in the long run due to the rising price of electricity.
With electricity rates rising all the time and the national average rising already this year, solar panels will be a good investment moving forward when it comes to the question of savings with solar power vs. electricity. If your average monthly electricity bill is high and you’re living in an area with expensive electric or gas rates, investing in solar could be amazing for your wallet and the environment,

Can I install my own solar roof?
Installation – It is possible to do the process of installing solar panels on your own. There are solar systems designed specifically for DIYers that, while sometimes time-consuming, should be more than doable. It’s worth noting, though, that many DIY solar panels are not designed to hook up to the traditional energy grid.
- They are designed more for off-grid purposes, like powering RVs or other spaces that are not typically served by a standard utility.
- If you are only looking to supplement your traditional energy source, DIY solar panels can get the job done.
- If you are looking to power your entire home with solar power, it might be better to trust an expert.
Installing a full solar energy system requires at least some knowledge of electrician work so you can properly handle the wiring and other technical aspects. You will likely have to work in relatively dangerous settings, including doing work on your roof and working with buried wires.
How much is a 1 panel of solar?
Type Of Panels – There are three main types of solar panels available for residential use. They are monocrystalline, polycrystalline and thin-film. The most energy-efficient and best solar panels for home option, monocrystalline solar panels, costs $1 to $1.50 per watt.
Do you need permission to install solar panels?
Stand alone solar panels on domestic premises (panels not on a building) – You need only apply for full planning permission (flats) or householder planning permission (houses) to install a stand alone solar panel when any of the following apply:
more than one stand alone solar panel would be installed. it would exceed 4m in height. it would be located 5m within the boundary of the property. it would be installed within the curtilage of a listed building, Curtilage means within the garden or grounds. in a conservation area, any part of the solar installation would be closer to a highway than any part of the house. A highway includes roads, paths and public rights of way. the surface area of any stand alone solar panel will exceed 9m² or any dimension of its array (including other equipment) would exceed 3m,
