Some Of The Longest Warranties In The Industry

While some brands only offer a 20 or less warranty. The solar panels that are used in these Grid Tie Solar Kits come with a 25 year manufacturer's warranty. The inverters come with a 10 year factory warranty, which are among the longest warranties in the industry.

Simply Better Components

In an effort to be more competitive, many dealers have resorted to offering thin light duty mounting rails that require many more roof penetrations, solar panels with poorer per Watt PTC ratings and lesser warranties and or solar panels that use cells that are not cut from a solid ingot of silicon.
Here at Discount Solar Supply we never skimp on quality. Every system that we sell includes only the very best heavy duty components available on today's market.
And that's not just talk. In a side by side comparison we'll prove why our name brand top of the line equipment outperforms the competition hands down at a price that can't be beat.



Were you nearly bamboozled by the lure of a what appeared to be a low price per watt, only to discover that the other dealer's low price didn't include tile hooks or flashings, or a complete permit submission package or a customized racking layout.

Your Solar Investment Is Only As Secure As The Mounting System That You Choose.

That's Why We Chose IronRidge Mounting Solutions For Our High Performance Solar Systems.

High Strength Aluminum And Stainless Steel


Important: If you've been provided with a quote with no mention of the brand or model number of the mounting system that your dealer is using, then we can almost guaranty that the dealer is probably trying to sell you one of the many low cost, thin aluminum racks that are available on the market. This is a common practice amongst less reputable  dealers. Always demand to see a full list of material including brands and models and ALWAYS ask for a copy of the mounting system's factory warranty.


Why Choose Discount Solar Supply ?

Unmatched Service

  • Our experienced staff will help you choose the right system.

  • We'll also help you fill out the State's paperwork.

  • Our factory authorized service center (One of the oldest and most experienced in California) will be here if you ever need our services.



These solar panels offer tighter power tolerances than many other brands. At 0 +5 watts you're guaranteed of getting more the the power that you paid for.


Here's A Shopping Tip

Just because a company makes  a great TV or other household appliance doesn't necessarily mean that they make a great solar panel. Some of the poorest performing solar panels are made by some of the biggest names in the industry.

Never rely solely on a salesperson to tell you what's a great product and what's not. We'll provide you with all of the resources that you would ever need, including specification sheets from our competitors offerings, so that you can make your own educated decision about solar panel performance and compare for yourself.

After all, solar panels have the potential to last 30 years or more, so even minor differences in performance can make a big difference in the long run.


We're Here To Help

We understand that solar energy may be new for you and that you may have many questions regarding your purchase, that's ok, you'll find that our staff is not only knowledgeable and friendly but actually enthusiastic about helping a customer with a new installation. All of us here at Discount Solar Supply Solar believes firmly in a clean renewable " Solar Electric Future " and anything that we can do to make that future a reality is our mission.

Electric Meter


With the cost of electricity going through the roof, it is now time to start thinking about your energy budget as a whole.

You can't make your own gasoline and you can't make your own natural gas, but now you CAN make your own electricity. And the best part about it is that the fuel to make own electricity falls from the sky everyday for free. 

Thousands of utility customers throughout the U.S., who were tired of the high cost of electricity have taken advantage of the huge rebates and tax credits which are available for the installation of solar energy systems on their homes and businesses.

For example, the Federal Government is offering a 30% tax credit with absolutely no cap residential and commercial applications. And unlike like the old solar energy systems of yesteryear that only produced hot water, these new systems actually produce electricity ! Clean reliable electricity to power air conditioning, lights, TVs, pumps, refrigerators, computers, virtually any appliance with free energy from the Sun.

The staff Here at Discount Solar Supply are experts in the design and implementation of systems that qualify for many State rebate programs. We offer free assistance in the design of your system and can even assist you with the submission of your application to your State.

Depending on the size system you choose and the number of loads you have running during the day, it is actually possible watch the power company's meter run backwards.



Only The Finest Available Products

Ask any alternative energy engineer, installer or dealer and they'll all tell you the same thing. With more than three gigawatts (3 billion watts) worth of Sunny Boy inverters sold and operating worldwide "The Sunny Boy inverter's proven technology makes this unit one of the best grid intertie inverters available on today's market." Like a fine German crafted sports car, Sunny Boy Inverters are engineered and built in Germany, the hotbed of the worlds finest renewable energy technology. We've taken Sunny Boy's unbeatable German craftsmanship and reliability a step further by adding one of the world's highest performance solar panels available.

When it comes to purchasing a solar system for your home or business it is crucial that you take a very close look at the solar panels that the dealer is offering you. After all, solar panels are the workhorse of any solar system. Far too many consumers simply purchase what ever it is that a dealer happens to have available without even looking at a specification sheet. Performance that is lacking by just a few percentage points or an inferior warranty can make all the difference in the world over the expected life of a solar panel.

With more than ten years of experience operating our own state of the art, in-house solar repair center, we know what technologies perform well in the real world and what technologies do not.

 Over the years, we've seen expensive, name brand, solar panels fail only after a few months worth of use. We've even seen popular U.S. made solar panels fail soon after the manufacturer closed its doors leaving its customers with no warranty.

This is why it is important that you choose a solar panel manufacturer that is well established in the industry and has the financial strength to be there if the need arises. This is exactly why we chose ReneSola our Sentinel series solar systems.

Thin might be in when it comes to waistlines and the latest HDTV sets but when it comes to securing the bulk of your investment to the roof of your home you want the strongest mounting system made out of the highest quality aircraft grade aluminum that money can buy. The engineers at IronRidge understand this premise and we do too so we've added the finest rail-less mounting system available today. IronRidge Solar Mounting Systems are unsurpassed in quality and durability, rated to withstand up to a 180 mile per hour wind speeds, Spider Rax Mounting Systems are engineered to last a lifetime.

Finally we top off our systems with the best price that you'll find anywhere. In fact, we're so sure that ours is the best deal available, that we'll beat any nationally advertised price on our same, in stock, top of the line systems or your system is free.


Unlike other dealers that will sell you a barebones system, our premium quality kits include everything you see listed above.

**(Your rebate amount may vary depending on expected system performance and will be calculated based on equipment ratings and installation factors, such as geographic location, solar module tilt angle and azimuth angle and shading.) Please note that many states and or utilities will use the the AC rating of the your system's equipment and not the DC rating of your system's equipment when determining the amount of your rebate. The AC rating of your equipment is typically calculated by multiplying the PTC rated output of your solar panels by the number of solar panels multiplied by the CEC weighted efficiency of your inverter, multiplied by your system's design factor which is based on module tilt angle, azimuth angle, shading and geographic location, multiplied by the current per AC watt rebate amount.

If you have paid in full for your solar system and have not yet received an approval for your rebate reservation, Discount Solar Supply will store your solar system for you at no charge until you have received your rebate reservation approval.
