Will a 20kW solar kit power my home?
For most homes or small businesses in the United States this 20kW PV optimizer kit is more than enough to completely eliminate their bill.
The 20kW size grid-tied solar kits include solar panels, inverter+optimizers, and the racking system for roof mount. These are complete PV power systems that can work for a home or business, with everything you need to get the system up and running. The kits include hardware components only; does NOT include labor.
A 20kW solar kit will require around 1,150 square feet of space. 20kW or 20 kilowatts is 20,000 watts of DC direct current power. This could produce an estimated 2,000 to 3,000 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South. The highest output will be achieved with an unobstructed south-facing view of the sun for maximum solar power. The actual power generated will vary based on location, equipment and installation factors. Refer to your electric utility bill to find the actual kWh used per month and compare it to how much power these low cost 20kW PV systems can generate.
The average American uses 920kWh per month. Based on that average this system could reduce your bill to ZERO. If you're an average consumer of electricity (920kWh/month), a 20kW system could probably give you the ticket to electric bill freedom.

Can I install the 20kW solar system myself?
- A 20kW solar installation can take three or four weekends.
- Our kits use industry leading solar panels, inverters, and racking systems specifically selected and combined to make do-it-yourself installation possible.
- A homeowner who has wired an AC outlet and is comfortable working on their roof can install our Solar kit.
The installation of a solar system, even from a complete kit is considered above the average homeowner's skill set and should not be taken upon lightly. Each task is rather simple, but you will be working at heights, on a angle, probably in the heat of the bright sun, working with power tools, hoisting large expensive pieces of glass up ladders and across a roof peppered with racking and wiring.
You'll also be working with DC voltages above 300VDC and household 240V AC. You should be good with simple math and be mechanically inclined. If you're willing to give it a try, it can be a rewarding experience both in saving you a lot of money and of giving you a great sense of accomplishment.
If self-installation is not for you, we can help you find a local solar contractor to help you with the process.
What is the solar installation process?
A typical solar roof mounted system for a home can be installed within 2 days once a permit is obtained from your city or county. After that, it’s just 5 easy steps until you’re producing power from the sun.
- Take your plan set to your city or county and apply for a permit to install. The plan review process can take up to 10 days. Once the city or county approves your plans and issues your permit you may begin installing your solar system.
- First, the racking and mounting system must be installed. This is the most laborious process of the solar installation process. You have to locate the rafters on your home and secure the racking system directly to them.
- Once the racking and mounting system is on your roof, the solar panels and inverters can be quickly installed. The inverter(s) are then tied into the grid through a dedicated breaker in your main service panel.
- When the installation is complete, your city or county inspector must sign off on it. You can accomplish this by scheduling an inspection meeting with them.
- Lastly, you must send the final job card, interconnection paperwork, and your net metering agreement to your utility. They will then grant you Permission to Operate. It can take up to 4 weeks after passing inspection for your utility to provide you Permission to Operate. With our interconnection service we will process all the paperwork for you.
Our job is not over until your system is producing clean energy from the sun! We offer you support throughout the installation process with manuals, videos, and technical support.

NOTE: Prices are based on average layout with average length wire runs. Your Complete Solar Kit will most likely be a couple hundred dollars below or above depending upon you home's requirements.
NOTE: You should also budget for shipping cost and if you're in California, Sales Tax.
NOTE: Production values can vary greatly, the numbers here are estimates based on averages.
For example a (33) 250W module system:
at 32 degrees tilt facing 180 south in San Diego could produce 1,104kWh/month
at 23 degree tilt facing 165 southeast in Massachusetts could produce 793kWh/month
Call 866-798-4435 to give us details about your house and we can quickly provide a good estimate of how much the kit would produce if installed at the proposed location under proposed tilt and azimuth. You'll need to provide your zip code, your roof tilt and compass heading of the roof pitch.
