Connect the solar panels either directly to a power inverter and then connect it to the home grid, or connect the inverter to the battery and then to the home power grid. This power inverter converts the solar energy into energy that is consumable at home.
Can I install solar panels on my home myself?
First off the good news, California does allow property owners to design and install their own solar systems on their own homes. The difficult part with this approach is that you have to know what you are doing and demonstrate your knowledge through accurate plan design and then proper electrical code installation.

How many watts of solar do I need?
Divide your average hourly wattage requirement by the number of daily peak sunlight hours for your area. This gives you the amount of energy your panels need to produce every hour. So the average U.S. home (900 kWh/month) in an area that gets five peak sunlight hours per day would need 6,000 watts.
What is the 120 rule?
Basically, the NEC 120% rule allows solar PV equipment to be installed in electrical boxes up to 120% of the installed electrical equipment safety label rating.
How do I know how many batteries I need for my solar system?
To determine the kwh usage of a battery, you simply need to multiply the Amp Hour (Ah) rating by your desired voltage system. To meet the requirements set by the previously mentioned average kWh the best battery bank size would be the 225Ah @ 12 Volt system with 2 batteries.
How much does a 12kW solar system produce?
A 12kW Solar Kit requires up to 800 square feet of space. 12kW or 12 kilowatts is 12,000 watts of DC direct current power. This could produce an estimated 1,800 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South.
Why is my electric bill so high with solar panels?
Solar power systems are finite resources—they can only produce so much energy consistent with the size of the system, and most utilities limit system size to the historical energy usage average at the site.
What are the 2 main disadvantages to solar energy?
Cons of Solar Energy Solar doesn’t work at night. Solar panels aren’t attractive. You can’t install a home solar system yourself. My roof isn’t right for solar. Solar hurts the environment. Not all solar panels are high quality.

How many solar panels does it take to run a house off grid?
Most data suggests that a typical American home (2,000 square feet home) consumes approximately 11,000 kilowatt-hours annually. So, when we divide our total consumption by the expected output of one solar panel, we see that roughly thirteen solar panels of this size would be enough to power a home of that size.
Do solar panels have to be on the roof?
Because they’re not dependent on your roof, ground-mounted solar panels are set at the perfect angle to optimize energy production. Most installers offer a ground mount option, and the cost of standard ground-mounted solar is comparable with a rooftop solar energy system installation.
Which direction should the solar panel face?
Direction. In the northern hemisphere, the general rule for solar panel placement is, solar panels should face true south (and in the southern, true north). Usually this is the best direction because solar panels will receive direct light throughout the day.
What do I need to install solar panels?
To set up a stable and flexible solar power system, you need solar panels, a charge controller, a battery and a power inverter. Solar Cells. The solar cells are the foundation of any solar power system. Charge Controller. Battery. Inverter. Grid-Tied Systems.
