* Even when appliances like TVs, VCRs and more are turned off, they still draw power
** Refrigerators actually cycle ON/OFF all day long to maintain their temperatures. To estimate the actual run-time at full wattage, divide the hours the fridge is plugged in by 3
Additionally, you can find the daily kwh usage of an appliance, by dividing the Energy Star rating by 365
|Humidifier||300 - 1000||CFL Bulb (40W Equivalent)||11|
|Video Game System||195||CFL Bulb (60W Equivalent)||18|
|Standard TV||188||CFL Bulb (75W Equivalent)||20|

|Cable Box||20||Clothes Dryer - Gas Heated||300 - 400|
|Clock Radio||7||Furnace Blower||300 - 1000|
Step 2: Determining Your Solar Resources & Calculating Your Solar Array Size Needs
Is your location a great spot for a solar power system? The chances are yes. You can use the table and the map below to determine just how much sun you really get at your home. With this information and a power load sizing sheet, you can determine exactly which of our off grid solar systems is the perfect fit for your power needs.
Buy Manufacturer Direct And Save Even More!
When you purchase through Silicon Solar, you will save as much as 20-30% vs buying your system through a local solar installer because you aren't paying a retail markup by buying manufacturer direct.
A solar installer may charge as much as $9.55 / watt (plus installation costs). But, at Silicon Solar, your system can cost as little as $5.95 - 7.95 / watt.
|System Size||Typical Installer
|1500W||$ 14,325||$ 10,155||$ 4,170|
|3600W||$ 34,380||$ 24,372||$ 10,008|
|4500W||$ 42,975||$ 30,465||$ 12,510|

Complete System Engineering & Design
For years, we offered our customer pre-packaged off grid PV systems, however, during that time we discovered that our most satisfied customers with the highest return on their investment were those who used our engineering professionals to design, purchase and install a custom cabin solar system carefully engineered to meet their specific needs.
Today, all of our PV system sales are engineered custom PV systems.
To get started:
- Determine your PV system size needs using the calculator to the right
- Contact our off grid PV professionals using the contact form to the right
- Place your $800 engineering deposit & design fee through your sales rep
- Purchase your recommended off grid PV system
- Let us arrange professional installation with one of our local PV installers
Note: Your design fee will be applied to your system purchae when you complete your order, or returned if you choose not to purchase through Silicon Solar.

Off Grid Solar Systems With Battery Backup Information Guide
Off grid solar systems are great for those who live in remote locations where bringing in the electric grid is extremely expensive or inconvenient or those who prefer to not have a monthly bill with the electric bill at all.
Off grid solar systems from Silicon Solar will include several critical components, including:High-Efficiency Solar Panels
Silicon Solar uses the most advanced and high-efficiency solar panels for our off grid solar systems. Designed and engineered to give you more power and a lower-cost, each solar panel used in our grid tie kits is approved and recommended for use all across the US and around the world.
The charge controller is a critical component of any solar power system with a battery backup. Overcharging is a major killer of batteries and a charge controller will monitor the charge level of your batteries and shut down charging to avoid damage once your batteries are full.
The battery backup is used in these off grid solar systems to provide power during the night or periods of bad weather when your solar panels can not generate enough power for you to use.
Solar panels and batteries generate and store power in DC (direct current), however nearly all home appliances and electronics use AC (alternating current) power that comes from the electric grid. A DC-AC inverter will transform the DC power from your solar power system into AC power that is useable right through your home's power outlets. A good, high-efficiency DC-AC inverter can make or break the performance and cost-effectiveness of a off grid solar system.
Other Important Components
- Solar panel mounting hardware
- Pre-cut wiring runs
- Solar wiring combiner box
- Battery storage box
- On-location & remote (online) monitoring system
- Lightning arrestors, breakers and other electrical components
- A backup generator (optional, but highly recommended)

About Off Grid Residential Solar Systems
Off Grid residential PV systems are solar powered backup systems for your home that have extra-high capacity battery banks to provide long lasting power to your most important appliances when you need them.
Your residential PV kit comes with a high-powered battery backup system (which provides emergency load power for your home even when the electric grid is down during emergency situations). Grid-tie systems cannot provide power directly to your house during a power outage due to safety regulations, but an off-grid residential kit is available for your use at any time.
Starting with high-efficiency solar panels, your pre-packaged residential solar system will include:
- High-efficiency solar panels
- Charge controller
- High-capacity battery backup bank
- Professional-grade DC-AC inverter
- Pre-cut wiring and combiners
- Backup generator (optional, but recommended)
For more additional information on each system component, please see the in depth breakdown below.
