Hyper X 2 Solar Logo Large



The solar leasing companies are still using much thicker, framed solar panels with a mono facial (single sided) glass on plastic design that originated back in the 1950's.
 Our lower cost, Hyper X2 solar systems include Gen 2 solar panels that have a much thinner, less than a 1/4 inch thick, frameless, semi transparent design that provides bifacial power production from both the front and back surfaces of the solar panel which provides extra power production with up to a 22% efficiency rating.
The new solar panels that are used in our Hyper X 2 solar systems offers a better PTC to STC ratio "Real World" performance according to the California Energy Commission's performance rating listings than over 119 of SunPower's solar panel models.

While the solar leasing company's more expensive, much thicker, Gen 1 solar panels might look good on your roof today, what will your home look like at year 10 of your locked in, 20 year lease, when many of your neighbors are installing, much sleeker, Gen 2 solar panels?
You can own this advanced technology for far less than what it will cost you for a zero down solar leased system. And if you need zero down solar financing, we offer much better $0 down loans instead !

Thinking About A Solar Lease ?

Better Think Again!


Purchase a solar system

A leased Solar System

A Purchased Solar System

Typical cost for an installed 4.75kW, $0 down, 20 year leased system after 20 years worth of $117 per month lease payments:


That's Nearly 3 Times The Cost Of A Purchase!

Typical cost from us, for an installed 4.75kW purchased system after applying the 30% federal tax credit:


Leased solar panels are typically made in China or some other foreign country.

These all black solar panels are made in the U.S.A.

 American Made Solar Panels

In the future, despite improvements in performance and esthetics, you don't own the solar system, so you can't sell the system or upgrade. You'll be stuck with the same aging solar panels on your roof for the 20 year term of your solar lease.

Since you own your system with a purchase, you can sell your system at any time and use the money to upgrade to the latest solar panel technology.

You're paying so much more for your leased system when compared to a purchase that it's actually you who will be over-paying for your own repairs, monitoring and insurance.

You'll save so much more money by purchasing your solar system and keeping the 30% federal tax credit, that even after typical repairs, monitoring and insurance costs, you'll still come out tens of thousands of dollars ahead over the life of your purchased solar system.

Check that leasing quote to see if that leasing company even bothers to mention the brand and model of the solar panels, inverter and mounting system that you're going to be paying for over the next 20 years?

You'll know exactly what your getting when you purchase one of our U.S. made solar panel based, higher performance systems, right down to the last specification. We don't try to hide the details. We're proud of the products that we offer!

Many leased solar panels offer a poorer temperature coefficient rating resulting in a -0.44% loss of power for every degree above 25 degrees C.

Our higher performance U.S. made Stion solar panels offer an industry leading -0.26% temperature coefficient rating for higher energy production in warm/hot climates.

Many leased solar systems include solar panels with standard PTC to STC ratios which according to the California Energy Commission, is an indicator of real world performance. A PTC to STC ratio of .890% to .905% is common for leased solar panels.

The higher performance, U.S. made Stion solar panels in these purchased solar systems offer a very high 92.92% PTC to STC ratio for better real world performance.

Imagine trying to sell your home in the future with 9 year old solar panels on your roof while trying to convince your homebuyer to assume the 11 remaining years on your solar lease. In addition, why would someone want to buy your home and assume your remaining payments on a used solar system, when they can buy a brand new solar system for less, and keep the 30% federal tax credit ?

Good luck!

Again, since you own your system with a purchase, you can sell your system at any time and use the money to upgrade to the latest solar panel technology if you wish. Plus, since you own the system, there won't be any payments for your homebuyer to assume.







The choice is clear. In most cases, if you want to rent a poorer performing solar system with Taiwanese/foreign made solar panels for the next 20 years, while giving away your 30% federal tax credit and any available cash rebate, and paying over 2 times more than what you would have paid had you purchased your solar system instead, then you should lease.

On the other hand, if that simply doesn't sound appealing to you, then do yourself a huge financial favor and purchase your solar system for a far better return on your investment.

Sales Policy









Solar Home specializes in solar power kits for home and commercial use. We offer wholesale solar prices to both homeowners as and solar contractors nationwide. Solar Home has offered solar energy for sale since 1997 and although our solar panel packages price is unbeatable, we do not offer cheap solar panels for sale. We offer only the best solar panels for home use with top name brands that you'll immediately recognize.

Solar Home is packed with solar power products and residential solar info that will save you thousands when compared to other solar panel suppliers. Wholesale solar prices is just the beginning of the solar home experience. Our Mitsubishi Electric PV panels have been installed on thousands of solar power homes and businesses. Since 1997 our home solar power kits have been installed in every state in the U.S. We're experts at designing and selling solar system products that last.

You can also buy solar panels wholesale from solar home. We are your home solar panel source selling high efficiency mono crystalline and poly crystalline solar power panels. You can buy solar panels online from the hundreds of dealer dealers that have cropped up over that last couple of years but buying solar solar panels that will still have a warranty in the next 3 to 5 years, now that's a different story.

From Raw Silicon To Solar Cells To Solar Panels.

Solar cells are solid state devices that are used in solar panels for the purpose of converting light energy (photons) into electricity (electrons) through a process known as the photovoltaic effect. The term "photovoltaic" is a Greek derivative coming from the terms (phōs) for light and "voltaic" for electricity. This first cell used Selenium and had an efficiency of about 1%. In 1954 while experimenting with semiconductors, Bell Laboratories introduced the first practical silicon solar cell which was doped with specific impurities that began the evolution of what would become today's much higher efficiency technology.

Solar panels that utilized these early solar PV cells had an efficiency rating of about 6% which was first demonstrated in April of 1954. Today solar panels have dropped dramatically in cost and have efficiencies ranging from about 6% for thin film solar panels up to 18% for front contact mono and poly crystalline technology. Modern panels are used in home solar power applications and Commercial Solar applications as well as off grid solar power and RV solar power uses. Panels systems are even used to provide emergency power and for Solar powered air conditioning systems in homes and businesses.

Mono Crystalline (Single crystal) Silicon Solar Panels

Mono crystalline or single crystalline cells are produced primarily by the Czochralski (Cz) process. The large diameter single crystal silicon ingots that are created from this process are cut into thin wafers using thin wire saws. Conductive energy collection grids are silk screened onto the surface of these wafers and a functional solar cell is produced. Solar panels for your home that utilize single crystalline cells offer among the highest efficiencies available on today's market.

Poly Crystalline (Multi crystal) Silicon Solar Panels

Cells that are created from polycrystalline or (multi crystalline) technology are cut from a silicon boule that has been casted from molten silicon and allowed to cool. The multi crystalline cell is grown from this silicon material forms multifaceted crystals that grows in different directions. Conventional multi crystalline solar cells typically offer a slightly lower efficiency.

Ribbon Silicon Solar Panels

A process which cost less than traditional manufacturing techniques is known as "Ribbon Growth". Silicon is formed directly into thin wafers which avoid the expensive process of sawing silicon from a solid silicon boule. One such method is known as "Edge defined film fed growth" starts with two crystal seeds. A thin layer of silicon is formed as the seeds are pulled from a molten vat of silicon which produces a continuous ribbon of silicon. Solar panels that that use this technology are effective at saving material but the quality of the material produced is not as high as the Czochralski (Cz) process. Cell efficiency may also be reduced. The one company that sold tens of thousands of solar modules in the U.S. that used ribbon silicon technology is now bankrupt which has left the homeowners that purchased these modules without a manufacturer's warranty. Solar home never sold ribbon silicon technologies. 

UMG Technology (Upgraded Metallurgical Grade Silicon)

In an effort to save on materials and processing cost. A few manufacturers have turned to less pure silicon to manufacture solar cells that are used in their solar panels. Unlike the nine 9s (99.9999999%) or even the eleven 9s (99.999999999) of purity that is the result of the conventional Siemens process, solar modules that are manufactured using UMG are of less purity which can have an effect on efficiency. Several Canadian based solar companies have introduced these lower cost, lower efficiency based products into the European and U.S. markets. Again Solar Home never has and never will sell UMG solar technology to its customers.

CdTe Solar Technology (Cadmium Telluride)

Like their crystalline silicon thin film cousins, Cadmium Telluride CdTe solar suffers from the same stigma of lower efficiency. The primary difference between both crystalline silicon and Amorphous silicon when compared to CdTe is that CdTe does not utilize silicon in its design.

Instead CdTe solar panels use a compound which is formed by a combination of Cadmium and Tellurium blended with Zinc. Another difference between CdTe and more traditional solar module technologies is that Cadmium one of the substances used to form the compound CdTe is an extremely toxic material with known cancer causing effects which raises concerns among health officials.

Cadmium telluride is toxic, but only if it is ingested or its dust is inhaled. There is also concern if it is handled improperly for example, without the use of appropriate gloves and other safety precautions. Although CdTe modules have been touted as being safe especially once encapsulated in a module, environmental concerns remain if these solar panels are not be disposed of or recycled properly should they become broken, defective, or decommissioned at the end of their life cycle. Due its potential for toxicity Solar Home will not sell solar panels that contain Cadmium Telluride.

Amorphous Silicon Solar (Thin Film Solar Panels)

Unlike crystalline silicon whose atoms are arranged in a very orderly fashion, the atoms in amorphous or thin film solar panels are not arranged in any specific pattern and in fact contain many structural and bonding defects. Amorphous solar panels are made by utilizing a vapor deposition process not unlike spraying the silicon which deposits a microscopic thin layer of doped silicon onto a glass substrate. Although thin film is less costly to manufacture than mono or poly crystalline technology they do suffer from several drawbacks, among them are a much lower efficiency. While mono and poly crystalline solar technologies typically produce power in the 12 to 15 percent efficiency range, thin film technology's efficiency range from 6 to 9 percent. Another drawback with Amorphous technology is an anomaly know as the Staebler-Wronski effect whereby the conversion efficiency of Amorphous solar panels has the tendency to degrade causing a drop in output of up to 20% when it is first exposed to sunlight. Due to it low efficiency Solar Home does not offer Amorphous Silicon solar panels.

With exception to AC solar panels that incorporate micro inverters and a solar module into a single unit, solar panels produce DC current. This is the same type of non varying current that comes from a flashlight or car battery. The voltage and current from a solar panel that produces DC power is constant in nature, varying only as the intensity of light that strikes the panel varies. Compare this to the AC current or alternating current that is produced by a battery based or grid tie only DC to AC inverter.

 When used in an off grid application, the solar energy that is produced by solar panels is first stored in batteries which is then fed to an inverter for conversion into AC current. This AC power can be used while the solar panels are producing power during daylight hours or can be used during nighttime hours from the DC energy that is stored in the batteries.

Inverters convert the DC current that is produced by solar panels into a sine wave current that is compatible with the utility grid. Grid tie only inverters do not store energy. A grid tie only inverter converts the DC power that is instantaneously produced by the solar panels during daytime hours and changes (inverts) this solar energy into AC power that is fed to the grid by synchronizing the inverter's AC waveform to the grid's waveform resulting in a reduction or elimination of the grid tie solar system owner's electric bill.

A third type of solar system is known as a grid tie battery back solar system has the ability to synchronize with and feed power to the grid during normal conditions but also has the ability through the use of a transfer switch and batteries to disconnect from the grid during a power outage as required by law and then automatically connect to a separate subpanel that has been installed at the system owner's home and tap into the battery pack to supply the home with electricity during both daytime and nighttime hours.

Grid-tied or grid-interconnected inverters come in many different varieties including conventional string inverters, inverters that use power optimizers for individual solar panel performance boosting and monitoring and shade mitigation and in recent years, micro inverters (a single inverter for each solar panel). Micro inverter have become popular but this older configuration is rapidly losing favor to the much higher performance power optimizer offerings. Solar Home does offer micro inverters but highly recommends against their use when compared to solar power optimizers.  

Solar panels are available from many different manufacturers but extreme care must be taken in today's economy if you are after solar panels that will have an enforceable warranty 25 years from now. Over the past two years, dozens of solar manufacturers like Solyndra, Abound Solar, Evergreen Solar, Energy Conversion Devices and Konarka Technologies have filed for bankruptcy. Others like Schott Solar have simply left the U.S. market. First Solar® and SunPower® both have cut production or suspended plans to build more factories. And according to Kyoda News, even Sharp® Solar will soon be leaving the U.S. solar market.

It has been estimated that more than 180 solar panel makers will likely disappear, going out of business by 2015.
