Set Up The Grounding For The Array
In order for the solar panel arrays to be safe for human hands to touch without being grounded, you will need proper grounding for them. To do this, bury a grounding rod with about six inches of its body sticking out. You can do this either on a wood surface or on the ground.
Once that is done, run a copper grounding wire from the rod to the fuse box and from the solar panels to the fuse box. The panels should now be grounded safely.
How Much Does It Cost To Install Solar Panels In General
There are two types of typical solar system installations: roof mounts or ground mounts. Roof mounts are typically less expensive to install because the roof is a ready-made structure, so they require less labor. Ground mounts, however, require a structure to be constructed to which you can attach your panels.
According to research from the EnergySage Solar Marketplace, the average cost of installing solar energy is $16,860. Design and installation labor costs will contribute about 10% of your total bill. These average costs are calculated before applying incentives and rebates, which can have considerable savings.
Solar systems qualify for several rebates, tax credits, and incentives across different states. These incentives can significantly reduce the final costs of installing a solar energy system.
Remember that solar is a long-term investment that more than pays off over time. It’s worth spending the money upfront on quality equipment and installation to see the return on investment later.

A case study: my friend R. runs a small solar panel system to power lights, her cellphone and a laptop battery in Ontario, Canada. Her fresh spring water is brought to the home and she uses compost toilets, so no need for power to run pumps. When her partner died she was worried about maintaining the DIY solar system her partner had built and maintained over the years. Some days she was running around the property looking for the energy hog and she needed some battery education from some local friends. In the end she was really pleased that she could maintain the system herself and be self-reliant, all on her own.

Connect The Cables To The Control Panels
Now that you understand how the wiring works for solar panels, you are finally ready to connect them to the house. So run the electrical cable from the solar array into the house through the underground conduit. Connecting the cables to a nylon rope can be used for easy threading, then pull through the conduit to inverter panels.
Connect the cables at the fuse combiner box located at the base of the solar array, this may vary depending on the brand. As mentioned above:
- The green cables are first connected to the grounding strip.
- The red cables are connected to the PV out positive terminal block
- And the black cables are connected to the PV out the negative terminal block.
Seven: Test The Solar Panel System
Once the installer or you, if youve been brave enough to try this has finished all of these steps, the last thing to do is make sure its all working properly.
This is just a case of switching the power back on and monitoring each part of the system to make sure things are ticking along correctly.

Diy Solar Panels Lets Talk About It
There are clear benefits to doing things yourself. The main benefit is saving money. There are many others, however, including learning a new skill, getting those creative juices flowing, and even finding a new hobby. But when we heard DIY and solar panels in the same sentence together, we had to check this out for ourselves.
As a company that owns our own utility-scale solar farms and provides electricity powered by that same solar, we were skeptical about these so-called DIY kits being offered on the market. After all, home solar installations can cost thousands of dollars depending on the size you want. Plus, it sounded a little too much like a science fair project.
But yes, you can indeed install your own solar power system at home, both ground-mounted and on your roof. However, the question remaining is: Should you?
Well, yes and no, depending on what applications youre looking for. Lets talk about the benefits of building your own solar panels, what application youd use to do such a thing and whether its worth it in the end to just call a certified solar installer.
Can I Build Solar Panels On My Own
Solar panels have increased drastically in popularity, as more people want to self-sustain their household with the electricity demands. To make solar panels more affordable for everyone in the UK, the government has set up incentives like solar panel grants. Even so, investing in solar panels can still be a considerable investment which some are not prepared to make. So what else is there to do? Build it yourself of course.
To get straight to the point, yes, you can build your own solar panels, or at least partially, depending on the craftsmanship of each person. The process DIY includes sizing the solar panel system, choosing which components suits your needs, mounting and installing the solar panels, the solar inverter and safety disconnects. Even if you do not fully install the solar panels, the more that is done, the less expensive it would be to hire a certified technician.
Installing Electrical System
Circuitry can be the tricky part of installing solar panels on your own, but with minimum knowledge about wiring, this can be achieved by anyone. Of course if you do not feel confident to do this part on your own, it would be best to hire a certified electrician to do the wiring and metering into your house.

The Purpose Of Self Installed Solar Panels
As I have touched on, most DIY solar panel kits are not intended to replace your traditional power source. Instead, they are there to offer a supplement to your power needs. Or they can be used for very small houses, a garage, or a shed. If you want to power a full-size home, it is advisable to seek professional service.
Another reason for installing DIY paneling, apart from those mentioned, is for it to act as a backup option if you lose power from the electrical grid. In this case, you will need to have a solar battery that can store the generated power.
Why Would You Build Your Own Solar Panel System
Forewarning: were not a solar panel installer, and we cant speak to exact amounts of how much installations cost and how much the market price of solar panels is at the time of this article. However, as a solar energy company, we can speak to the feasibility of installing solar systems and whether we think you should dive into building your own.
Having a professional install something costs money. If youre considering DIYing your solar panels, this clearly isnt your first rodeo. However, home solar panels arent your typical set of IKEA furniture where you can essentially furnish and build an entire house.
Solar panels are intricate and require a certain amount of trade knowledge to install them correctly. Therefore, to save money, you must spend time researching and carefully following the directions on your solar installation kit. What you save in cash might not be worth the time it takes to accrue the knowledge you need to do the job right.
That said, if youre installing a panel system on, lets say, your RV, boat or tiny house, then the process is much less complex than in a multi-panel system that must be wired into the electricity grid. Therefore, it might be worth looking into.

Inverter And Battery Stand
I made the above inverter and battery stand by the help of a carpenter. The design idea I got from this instructable. The design is really helpful for me.
At the backside, I made a big circular hole just behind the inverter fan for fresh air suction from outside. Later I covered the hole by using plastic wire mesh. Few small holes are also made for inserting the wires from solar panel, charge controller and inverter to the battery and ac output to the appliances. At both sides panel, 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications in the inverter.
In the inclined plane of the inverter stand, I have mounted the charge controller. In the future, I will install my own made energy meter also.
Wiring The Conduit To The Solar Panel
For you to be able to carry out this next process, you will need to have either a junction conductor or a fuse combiner box. Once you have one of the tools, you are good to go.
The modules of the panels are usually stripped and wired in pairs. You need to confirm that the wiring is proper from the solar panel modules, and once you know that they are well connected, you will need to connect the wires to the fuse box connected to an underground conduit cable.
If you do not have any idea when dealing with electricity, it is advisable to hire an experienced electrician who will help you connect the wires to the fuse box. It would help if you always took precautions when dealing with electrical equipment.
The next thing you need to do in the terminal box is making sure the stripped wires are correctly connected. The red wires in the terminal box need to correspond with the junction boxs red wires, and the black negative wire should also correspond. Once they are all connected, your solar panel is ready to start functioning.

Determine The Best Positioning Of The Sun And Secure The Rear Legs
Now for ground platforms, you definitely have a lot more freedom with choosing how to install the solar panels. You can also decide which direction they need to face for optimal sunshine. However, make sure that you use meteorological data to determine the movements of the sun in your area, this way, you can maximize sunlight based on the angle and position of your panels.
For sun movements in your area, you can use this website. One thing to note is that its not actually the sun that is moving, but the Earth, but for the sake of simplicity, lets just assume its the sun and the sunlight which adjusts.
Once you are done with calculations, use the rear legs to elevate and tilt the solar panel towards the best direction and angle where it can catch the most sunlight. Make adjustments to the rear legs length accordingly before fastening the panel to it.
You Know The Basics But How Do You Know How Much And What Types To Buy
There are multiple types of solar panels, some more efficient, some better for smaller spaces, some better for people with more land, crystalline, thin-film, cheaper, expensive. The options are vast. So, where do you start?
You start by monitoring your energy consumption. You need to have a good idea of how much energy you consume on the average day to determine how big of a solar energy system youll need. On top of that, youll also need to know how much money you have to spend keeping in mind that the most expensive solar panels might not be the most cost effective for your needs.
Crystalline solar panels (both monocrystalline and polycrystalline solar panels are more efficient than thin-film solar panels. But, theyre also more costly because they are more pure. Monocrystalline solar panels have been found to capture about 18-21% of the suns rays, where thin-film solar panels average around 15%. All panels have an average life span of 25+ years crystalline silicon solar panels have lifespans up to 40 years. Intuitively, the more efficient the panels, the less youll need to buy.

Fully powering your home, vehicle, cabin, or boat by the sun in 2020 has never been easier. For starters, the International Energy Agency recently stated in its 2020 Outlook report that solar energy the new king of electricity is the cheapest form of electricity ever created. So, significantly reducing or even eliminating your utility bills with DIY Solar is a near certainty now.
Better yet, the cost of materials needed for home solar has plummeted in the last decade . The biggest reason for the price drop lies in the photovoltaic panels themselves: 90% reduction in price from $2/watt to a measly $0.20/watt!
On average, in the United States between 2010 and 2020, the cost of installing a residential solar system fell from $7.50/watt to $2.50/watt.
This means your upfront costs are lowered, and your payback period is shortened. In as little as 5 to 10 years if youve done everything right its reasonable to believe that your DIY solar system will begin making money for you. This is great for both you and the planet.
Net Meter And Battery
For a solar array, you need a special net meter that can spin backwards when you add power to the grid. Your power company should provide one for free. A battery backup is an extra option, but theyre very useful in the case of a blackout, and youll need one for an off-grid system.
There has never been a better time to switch your home over to solar power. Costs of solar panels are dropping rapidly, and government financing incentives make the project affordable for most people. Not only will you have bragging rights of being the only house on your block with solar power, but it will save you a lot on energy bills.

Fasten The Upper And Lower Aluminum Rails
How many solar panels youll have will determine how long each rail will be. Assuming you already picked the appropriate length of rails, the next step requires you take your aluminum rails which will be holding the actual solar panels and mount them horizontally when facing the roof head-on. Use stainless-steel bolts to do the mounting to ensure your whole system stays resistant to weather.
When you are done mounting your rails, measure diagonally across from the end of the upper rail to the end of the lower rail. Repeat for the other sides to make sure everything measures equally.
Since we are doing a single array of solar panels, youll want to make sure the distance between each side is appropriate to the size of your solar panels vertically.
