To power a 3 bedroom house you need to have at least 19 of the 315 watt solar panels with a 5.82 KW solar panel system.
However some people may need a bit more solar panels depending on how much electricity they use.
Solar power inverters last between 10 to 15 years.
As long as you don't overload the solar power inverter or they don't get struck by lightning etc then they should last at least 10 years although some may last 15 years.
A hybrid solar inverter can be used without a battery.
However regular power inverters cannot be used without the battery as they require the power from the battery to operate.
The solar panels charge the battery and then the power from the batteries is then drawn out and into the power inverter which is then used and converted into AC power to be used.
To make money from solar panels you sell back some of the unused electricity to the power grid.
If your electric utility allows it and approves it you can setup your solar panels to sell back unused electricity to the power grid.
The electric utility then uses a meter that reads backwards to credit your account so they then owe you money.
A smart meter for solar is a meter that measures the power from your solar panels and when connected to the grid your meter can back feed power from the solar panels into the power grid.
Then the smart meter can record backwards and credit the power sent to the power grid if your solar system is a grid connected solar system.
Some people also use a smart meter on their incoming solar line to measure how much power they are using for their personal use.
MPPT in solar panel means maximum power point tracker which is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid.
The best solar inverter for home is 5KVA/48V MPPT Solar Inverter.
The Mitsubishi FR-D720-0.75K solar inverter system is also another best solar inverter for home.
The voltage that your solar panel should be depends on the watts you require.
For 200 watts or less the 12 volt solar panels are good enough while for watts above 200 watts and in the 300 to 800 watt range or so the volts should be 24 volts and above that you should get 48 volt solar panel systems.
The best voltage for a solar system is between 12 volts to 24 volts depending on the wattage you want and need.
For solar panels and solar systems that power around 100 to 200 watts then 12 volts is usually good enough but for wattage above 200 watts then having 24 volt solar systems is better.
Solar panels do not work at night as they require sunlight to work.
However when it's cloudy and there's at least some daylight the solar panels will still work.
But once it becomes dark for the night the solar panels stop charging but the power stored in the batteries can still be used but they won't charge until the daylight or sunlight comes out.
Solar panels when installed correctly on your roof do not damage your roof.
Solar panels installed on your roof can usually make your roof last longer as it protects the shingles from the elements.
However if not installed correctly then the solar panels may damage or ruin your roof.
Solar panels can and do sometimes catch fire but it's rare for solar panels to catch fire.
Solar panels may catch fire due to shorting out through the wiring or by a defect in the solar panel.
Although most solar panels are safe when installed correctly and many solar panels operate just fine and safely without any fires.
Solar panels don't always affect your house insurance unless you want to increase your insurance coverage to cover the cost of the replacement of the solar panels and system should you need too in case something happens to them.
Simply installing the solar panels on your house or near your house won't and should not change or affect your house or homeowners insurance.
PV on a meter box means Photovoltaic which means that the meter is connected with solar panels and usually has solar power feeding backwards into the power grid depending on how it's set up.
Sometimes solar panels are set up to where they will feed excess solar energy back through the meter and then the customer of the electric utility gets credited.
PV on a solar charger stands for Photovoltaic.
Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry.
The photovoltaic effect is commercially utilized for electricity generation and as photosensors.
Another name for a solar panel is photovoltaic cell or solar collector.
A photovoltaic cell (PV cell) is a specialized semiconductor diode that converts visible light into direct current (DC).
Some PV cells can also convert infrared (IR) or ultraviolet (UV) radiation into DC electricity.
Most solar panels last between 20 to 25 years before they need replaced.
Some solar panels may even last as long as 30 years but the average lifespan of a solar panel is 20 to 25 years which is pretty good.
Solar panels are a good investment especially in areas where electric rates are high.
Although you need to purchase the solar panels, batteries and inverters they are a good investment and can save you money on your electric bill.
Also when the power is out such as due to a storm etc you can still have electricity as long as the sun is shining and you have enough charge in your batteries.
To run a house off of solar panels you would need between 20 to 24 solar panels.
However smaller houses with less electricity usage may get by with around 10 to 15 solar panels but it's always good to have more solar panels than needed to provide you with plenty of electricity.
Solar and wind power can power at least 85 percent of Americas energy needs.
However there's not enough solar or wind power available to provide all of America with electricity so we still need some coal, natural gas, nuclear power plants etc to provide some of the electricity that we use.
The amount of solar panels it would take to power the entire united states is at least 7.85 billion solar panels and those solar panels would need to provide at least 350 watts each per hour.
Solar's abundance and potential throughout the United States is staggering: PV panels on just 22,000 square miles of the nation's total land area about the size of Lake Michigan could supply enough electricity to power the entire United States.
The amount of solar panels that would be needed to power the world is at least 51.4 billion 350 W solar panels.
With countries racing to end their reliance on the fossil fuels that cause climate change, it's a boom time for renewable energy.
Now, an international team of researchers has determined that if every available rooftop was equipped with solar panels, they could generate enough electricity to power the world.
Solar panels do work some when the weather is cloudy although the solar panels charge slower when it's cloudy out.
Solar Panels work best when the sun is shining really bright.
In the hot summer sun the solar panels produce the most power.
You can even power window air conditioners with solar panels if you have enough solar power and a big enough inverter and battery bank setup.
