Use A Heat Pump Water Heater
This is a type of storage hot water heater that uses an electric heat pump to heat up the water. These are much more efficient than conventional electric water heaters. However, they are also very pricey: 2 to 4 times more expensive than a natural gas or electric resistance water heater.
Thereâs a downside with using a heat pump water heater in a cold climate, however. Because the heat pump extracts heat from the indoor air, using a heat pump water heater in a cold climate will cause your furnace to work harder. This is a bit of a zero sum game, so if you live in a cold climate, it would probably make sense to stick with a natural gas heater. Heat pump water heaters can be a great choice in warm climates, though.
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.
Get A Solar Panel Installation For Your Home
Now you know approximately how many solar panels you need for your home. Of course, the best idea is to get in touch with a solar company so they can go over your needs and what your property is like. From there, they can give you a better estimate of the number of residential solar panels you might require.

Why Bother With Solar Panel Installation
In 1954, Gerald Pearson developed the first silicon photovoltaic cell. This ultimately lead towards the development of solar panels in the applications we see today.
As mentioned previously, most have been slaves to electric companies for more than a century, paying unreasonable rates with no other perceived options. Today in the 21st century, solar energy is taking off like a ROCKET and year by year they are getting cheaper to buy.
At first glance it may seem intimidating with the thought of having solar panels, after all its totally normal when you dont know how the system works and is hooked up. But before you go any further, Id like to inform you that you can install your solar system at home no matter what size with relative ease. As long as you follow the instructions, you will have the required knowledge to get the job done for yourself.
If you are a bit adventurous and are willing to get your hands dirty, professional installation wont be a total requirement.
Run Solar Panel Dc Power Into A Charge Controller
In the example above as we have shown, we had 4x 100 watt solar panels putting out 400 watts max, so we are going to match THAT with the appropriate solar charge controller.
Each 100 watt solar panel would put out MAX of 22.5 volts and around 5.29 amps. All 4 being wired into parallel, we would have 22.5 volts MAX and about 21.16 amps MAX. For this setup, we found a PWM Charge Controller with 40A and can have 12 or 24 volt input. This should cost around $30-$40 dollars. Connect the solar panel positive and negative terminals into the PV inputs on the charge controller.

Its time for the litmus test that tells you whether to proceed boldly as an amateur solar installer or to hand over the reins to a professional. For most of you, the decision will come down to the rules of the local building authority or your utility provider, either of which may require that solar installations be done by a licensed professional. This is also the best time to confirm that your project wont be nixed by your zoning department, historical district standards, or your homeowners association.
WARNING: PV systems are inherently dangerous and potentially deadly. As a DIY system installer and owner, you must understand, respect, and mitigate the risks involved with all installation and maintenance tasks. Pay special attention to safety warnings as well as all requirements in the local building and electrical codes and equipment instruction manuals.

So, are you excited to generate FREE electricity from the sun by learning how to make a solar panel? This is where you can take the help of this guide.
Are You Skilled Enough To Build Your Own Solar Panels
Solar panels are relatively simple enough to build, but for them to remain functional for a long period of time, they need to be built with extreme precision. Solar panels need to be able to maintain their integrity in harsh weather conditions and from consistent exposure to heat and sunlight.
Safety is the biggest concern with homemade solar panels. Moisture can get inside and ruin them and there is the potential for improperly built panels to catch fire from the suns heat. Mastering the soldering and electrical wiring is a challenge that generally takes the knowledge of a skilled electrician or engineer.
Building a system requires a willingness to research, make mistakes, and gain experience in electrical wiring skills and soldering techniques. So if you are an experienced engineer or electrician, this can be a bit easier to master but it is definitely not a quick weekends worth of DIY-ing.

Building Your Panels Cheaply
Now that you understand the process for building your own solar panels, I’ll describe a couple of ways that you can use to reduce the cost of building them.
The most expensive components of a DIY solar panel are the solar cells. By using less expensive solar cells, you can significantly reduce the cost of your panel.
The easiest place to find cheap solar cells is on ebay. You may also be able to find discounted or free solar cells by checking with your town’s highway department for damaged cells from road-side lights or a local solar installation company.
But the BEST way to reduce the cost of making your own solar panel is to follow a detailed guide. You could use the instructions on this page to successfully build your own solar panel, but it would require some trial-and-error, which costs you both time and money.
To save you time, effort, and money, I recommend you use the Earth4Energy DIY solar power kit.

How Much Would I Be Saving To Install Them Myself
Now that weve established DIY solar panels are for small, off-the-grid solar projects, lets get into the costs. Youre probably not going to be satisfied with this answer, but it truly depends on which company you go with and how big your installation is.
Our recommendation? Get a bid first it cant hurt to know how much its going to cost. In fact, you must know how much it will cost a professional to truly know how much youll save. Every solar installation is different, so knowing how much yours is will matter.

Thereâs something of an 80/20 rule when it comes to net zero homes. That is, you can spend relatively less money to get most of the way toward a net zero house, but the final steps to get to 100% energy self-sufficiency can get very expensive.
Assess Your Solar Potential
Before deciding on the best way to use solar electricity at home, assess the potential solar energy that can be produced at your address. Because PV technologies use both direct and scattered sunlight to create electricity, the solar resource across the United States is ample for home solar electric systems.
However, the amount of power generated by a solar energy system at a particular site depends on how much of the sun’s energy reaches it, and the size of the system itself.
Several mapping services and tools are available to help you determine your homes solar energy potential. Some of the services also offer information on the estimated system size, potential costs and savings, and local contractors.
These tools are an excellent starting point and can help you determine whether your home is suitable for solar, and if not, the best path forward for still benefiting from solar. While these tools are helpful, they don’t account for all of the variables that need to be considered for your particular system. For that, you will need to work directly with a solar installer who can provide an accurate assessment of your solar potential as well as detailed recommendations, estimates, and equipment expertise.
Consider the following:

Assess Your Options For Using Solar
Purchasing and installing a system that you fully own and maintain is no longer the only option if you want to go solar. Even if you rent your home or don’t want to purchase a rooftop system, there are many programs will enable you to still benefit from solar electricity.
Below are some of the options available for using solar energy at home check with local installers and your utility for programs available in your area.
Purchasing a Solar Energy System
Purchasing a solar energy system with cash or a loan is the best option when you want to maximize the financial benefits of installing solar panels, take advantage of tax credits, and increase the market value of your home, and a solarize program is unavailable or impractical.
The solar installer will connect the system to the grid, and receive an interconnection permit from the utility. When the PV system generates more power than the homeowner requires, the customer is often able to sell excess electricity to the grid, and when the homeowners electricity needs exceeds the capacity of the system, the home draws energy from the grid as usual. Learn more about grid-connected home energy systems.
Purchasing a solar energy system is a good option if one or more of the following apply to you:
Community or Shared Solar

Can Be Expensive When You Install Solar Panels
While solar panels definitely provide you with a cheaper alternative, at the time of installation they can cost you a lot of money. The more you need energy, the more will be the installation cost.
The cost of the entire installation process will include paying for solar panels, solar powered batteries, wiring, inverter, and lastly, for the installation.
On the bright side, the government can give you credits for adding the solar panels, and there are some providers that aim to fund your installation. However, these options are not available to everyone. For some, reducing the costs of solar panels is not an option.
The installation procedure and funding depends on where you live and what your payment plan is. In a way, your energy savings could be equal to your monthly payment.
However, because solar technology is constantly growing, there are chances that the costs may come down in the coming years.

How Many Solar Panels Do You Actually Need For Your House
In the last 5 years, the overall number of solar installations has exploded from around 40,000 to almost 110,000! Were becoming a greener society, and the dropping prices of solar panels dont hurt either.
Now that solar power systems are more accessible and affordable, you might be considering home solar panels. That way, you can do your part in looking after the planet.
How many solar panels do you need for your house though? Read on to find out!
Can Mobile Homes Be Powered By Solar Energy
Around 1839, it was discovered that certain materials would produce electricity when exposed to light. It was around 37 years later when the discovery was made that selenium exposed to light produced energy. It was yet another 100 years before the first practical solar cell was patented using silicon.
In the 60s and 70s, efficiency levels rose from 1-2% to around 10%, and solar-powered watches and calculators became available for purchase. By the 80s, solar power was available to the average American, and tax credits and incentives for installing renewable energy sources in the home were made available through federal acts. Solar power continues to grow in popularity and to shrink in price per watt.

How Solar Panels Work
Solar panels work by letting photons from the suns rays knock electrons free from atoms inside of photovoltaic cells to generate a flow of electricity. Each panel is composed of many solar cells linked together . Each cell contains a positive and negative layer that combine to form an electrical field in which energy is created.
Phosphorus inside the top silicon layer creates the negative charge, while boron in the bottom layer provides the positive charge. The two fields interact with one another to turn the suns rays into the energy that flows from your panels to your inverter.
Can A House Run On Solar Power Alone
Practically, it is not often possible. This is because solar only works when the sun is shining – which means when it is cloudy or nighttime, they do not generate electricity. There are some battery solutions to provide power during these times, but they still tend to be quite expensive. Most homes with solar panels still rely on the grid from time to time.
