My Thoughts Of The Whole Project
Overall, the project was a fun experience, and the total amount of money that I spent was around $400-$500, which includes the battery, charge controller, and deep cycle battery. So I saved a large portion by building my own solar system, since a commercial solar panel would have cost $400 on up for just the solar panel itself.If you have any questions or concerns, just visit GreenTechTown.com’s Forum and I or other members will try to answer them as quickly as we can. This is a free resource including the videos, so be sure to share this with others.
Panel Arrays And Connection:
I always recommend starting with a smaller 12-volt panel. They are not oversized, and one person can easily handle them. Two 12 volt panels can be connected together in series to make a 24-volt system or four 12 volt panels in series to create a 48-volt system.
To get more current, you can connect four panels in this way make two pairs of panels by connecting each pair in series then connect two pairs each other in parallel.
What Are The Pros And Cons Of Diy Solar Panels And Solar Systems
Most DIY projects have their pros and cons, but because solar systems deliver electricity to your home, having properly made panels is very important. It is the difference between saving a few thousand dollars versus having solar panels that you know will be safe.
As you can see, the cons greatly outweigh the pros.

Introduction To Solar Cell Or Photovoltaic Cells

A solar cell is a device that produces electric current either by chemical action or by converting light to electric current when exposed to sunlight. For the sake of this article, attention will be given to solar cells only.
A solar cell is also known as photovoltaic cell which produces electric current when the surface is exposed to sunlight. In the course of this article, we will be making reference to sunlight as electromagnetic radiation .
In solar cells, the amount of electrical energy generated by the cells depends on the intensity of em radiation that reaches the surface of the cell. Solar cell converts em radiation to DC current. Thus we can say that a solar cell is a semiconductor junction device that converts electromagnetic radiation reaching us from the sun to electrical energy. As stated above, the current generated is DC.

Testing Solar Cells Output:
Before constructing the panel, you need to test each and every cell that you are going to use in your project. If you are working with off-spec, then cells need to be categorized in low, medium, and high output. One low current cells can bring the output level of other high current cells to the low rating.
Although, you dont need to get the exact output from each cell, but they should be a level of what the panel is capable of producing.
For the best results, cells need to be tested in the bright sunlight when the sun reaches above your head. But, you can test the output level of cells at any time of the year. Keep in mind, the output level will vary according to environment and weather.

How Do You Build A Battery Bank For Solar
Its possible to build your battery bank to supplement your solar panel. Ive outlined some necessary steps you should follow when designing and creating your own battery bank.
1.Calculate your load
The load is the amount of electricity you usually use on a day to day basis. This can quickly be done by carefully examining your electricity bills for the last 12 months. Once you get that amount, divide it by 365 to acquire the load.
2.Calculate the Backup power
Once you know your load, the second step is to calculate how much backup power you require. Usually, people need a backup power of roughly 2-4 days.
3.Connect batteries
There are two ways to connect several batteries. Each method has specific advantages.
In Series
When one positive terminal is connected to another batterys negative terminal, this arrangement produces much more voltage value.
In Parallel
This is when the positive terminal of one battery is connected to the next batterys positive terminal. The same goes for the negative terminals.
This arrangement increases the total capacity of the battery bank by increasing amp-hours.
The inverter is one of the most critical parts of a solar panel.
It transforms both the solar panels DC output and the power stored in the batteries into usable AC. Keep in mind that the inverter does not have storage capacity and should be large
enough to handle the maximum load imposed on it at a case.

Assembling The Solar Cells
In step 6, plan at which position each cell will be placed. Later on, you can begin connecting the cells. In order to get the highest voltage, the cells must be connected in series. For instance, if you have 36 sections equalling 63 watts, the best layout would be four solar cell columns, each having nine cells connected in series.
When connecting, the rest of the cells repeat the above steps.
Ensure to join as many solar cells as required to reach the least voltage of 12/24 volts. This voltage is needed to start a 12-24 volt inverter. The voltage is converted to 110/220 volts AC by the inverter.

Monocrystalline And Polycrystalline Cells:
Monocrystalline and polycrystalline cells have an efficiency of 15% and 8% respectively. Out of these two silicone cells, Monocrystalline produces more electricity in the given area as compared to polycrystalline cells.
However, Monocrystalline cells are more expensive as well.
Both of these cells are fine for the construction of the solar panels, but if you want to generate more electricity in a given space then go for Monocrystalline cells.
Both of these cells come in many different sizes. Some of the common shapes are round, square, pseudo-square, and rectangle.

What This System Provides:
An alternative energy system can be used to provide electric power to any number of electric devices, such as appliances, tools and computers. The bigger the system, obviously, the more power it will provide. To give you an idea of the capacity of a small system like ours, here is what we use our solar energy system to power:
Refrigeration: This is a DC powered refrigerator, the same size as a conventional chest freezer . The refrigerator draws 40 watts of power and can be converted to a freezer by replacing the thermostat. Since the refrigerator is a DC model, it is wired directly to the battery, bypassing the inverter. So the refrigerator keeps running even if the inverter is turned off. Our refrigerator has been running continuously for over 8 years without any problems. Even during the dark days of winter, the solar panels provide adequate power to keep it running.
Music: Our home has a Vers sound system which lets us use an iPod or direct cable from an iPhone or computer to deliver a rich sound while drawing relatively little power. We can run this sound system about 3 hours a day in winter, and as much as we want in summer.
Light: The big change for our home is electric lights. We have replaced our kerosene lights with a few of these LED lights, which are only 7 watts each.
Small tools and appliances: The system also recharges small tools, such as a battery-powered driver-drill. Our system recharges the battery for this tool in about 30 minutes.

What Are Other Benefits Of Professional Installations
The cost of a solar system installation can be intimidating – however, there are many financing options like solar loans, as well as incentives for homeowners that can drastically reduce the price.
While solar system installation costs are expensive, installers have decades of hands-on experience something no amount of research or instructions can duplicate.
At the end of 2020, the federal tax credit was extended, so you can get a tax credit of 26% on your solar system until 2023. To reiterate, you would not be eligible for this incentive if you built and installed the panels yourself.
DIY solar panels and solar systems are possible but are best left for science projects or small-scale use. Professional installations might not give you the satisfaction of completing a project, but they can give you peace of mind.

Our Simple Diy Home Solar Power System

This basic off-grid solar power system is simple to install and can be easily expanded
- Off-Grid & Preparedness
Bringing some of the benefits of electrical power to our off-grid home has been a hit-or-miss affair. Over the years weve tried some very simple approaches to lighting and small battery recharging for our flashlights, such as hauling a 12 volt car battery to a small rural school about a half mile away every time it needed to be topped up. This was time consuming and inefficient.
But we didnt want to lose the feel of our simple home by bringing in a large generator and the jugs of gas needed to run it, and the prospect of setting up a wind turbine or solar array seemed expensive and a technological eyesore in a natural setting.
Editors Note: This article was first posted in 2012. Since then weve made a few upgrades to our system that are reflected in this updated version. Basically, weve added a couple panels and got a larger capacity charge controller, and added a battery charger to supplement the system during the darkest weeks of winter when solar power is at a minimum.
