How Does A Hybrid Solar System Work
The array of solar panel in a hybrid solar system is interconnected with the inverter, which is further linked to the solar battery and utility grid. The solar panel absorbs the sunlight and converts sunlight into direct current electricity. This electricity then goes to the connected solar inverter that further converts direct current power to alternating current . This alternating current is the standard electrical current used to power our household appliances and luxuries.
During the day, if the solar systems output exceeds the electrical needs of your house, the excess energy is then stored in solar batteries and once the batteries are fully charged, the electricity is automatically exported to the utility grid via Net-Metering.
For night, you will have 2 options in the inverter grid and up to 50% batteries. If you choose govt power/grid, the grid will run your load and in case of power cut, solar batteries will power your home. If you choose the battery for second priority, the battery will be drawn up to 50%. In case, your household consumes more than 50% battery, the extra electricity required to power the house is drawn from the utility grid.
Your homes power performance will be the same whether the electricity is being drawn from the solar panel, solar battery, or utility grid.

In near future, India will explore new potential areas and ensure the maximum use of solar power get world leadership. The National Institution of Solar Energy in India has determined the countrys solar power potential at around 750 GW. India is slowly going to get its dominion in the field of solar power generation due to the ambitious state and centers solar policies and projects.
Nowadays India starts switching to solar energy that is one of the best financial decisions in todays world. As we can see the prices of fossil and fuels are increasing day by day so this is a perfect alternative to this problem. Although, India has huge scope in the field of solar energy in near future because solar power for home and industries are a cheap source of clean energy and secondly, it is available widely across the country without any interruption.
How Much Roof Space Is Needed For Solar Panels
The average solar installation will require between 335 and 405 square feet of roof space. To find out how much roof space your solar system needs, just multiply the number of panels you need by 17.55 square feet, which is the area of most residential solar panels sold today.
If you have limited roof space, you may need to get high-efficiency panels, or panels with a higher power output so you can install fewer panels while still covering your energy needs.

How Many Kwh Can Solar Panels Produce
Another important question that many people keep on asking and whose answer is essential if you are to understand the amount your panels are giving you. As discussed above, the amount of kWh that a solar panel can produce is dependent on several factors.
The first one is the number of hours the panels receive direct sunlight, and secondly, the power rating of the panels.
For example, if you have three solar panels, each having a power rating of 250 watts, and they receive 5 hours each of direct sunlight, the total kWh will be as follows:
250 watts * 5 hours of direct sunlight * 3 = 3750 watts per hour, which is equal to 3.75 kWh.
The total amount of energy per hour, is always dependent on the number of panels, the rating power of the panels, and the number of hours the panels receive direct sunlight energy.
With that in mind, it becomes easy to know how much is your solar panel production. It will also help you to see if you need extra power to fit your needs or not.
How Much Do I Save
Finally, lets find out how much you can save per month on average from your monthly electric bill!
Lets plug it all in:
On average, your solar system is going to lose some energy due to wiring, power, inverter efficiency, so you actually end up using 80% of your solar systems capacity.
To figure out how many kilowatt-hours your solar panel system puts out per year, you need to multiply the size of your system in kW DC times the .8 derate factor times the number of hours of sun. So if you have a 7.5 kW DC system working an average of 5 hours per day, 365 days a year, itll result in 10,950 kWh in a year.
If you divide your expected 10,950 kWh of annual production by 12, youll see that your system will offset about 912 kWh per month from your monthly electric bill, which can translate to $100 or more per month depending on how much you pay per kWh!
So to break this down into simple math that you can do:
AC rating = Average kWh per month / 30 days / average sun hours per day
example: 903 kWh per month / 30 days / 5 hours = 6.02 kW AC
DC rating = AC rating / derate factor
example: 6.02 kW AC / .8 = 7.53 kW DC
Number of panels = DC rating / Panel Rating *note this is important b/c panels are rated in watts, and the systems are rated in kilowatts . So a 7.53 kW system = 7530 Watts and a 250 watt panel = .250 kW
example: 7.53 kW x 1000 / 250 watt = 30.12 panels, so roughly 30 250 panels

How Many Kwh Can Your Solar Panels Produce The Complexities Of Production Ratios
The amount of power your solar energy system can produce depends on how much sunlight exposure your roof receives, which in turn creates your production ratio. The amount of sunlight you get in a year depends on both where you are in the country, and what time of year it is. For instance, California has more sunny days annually than New England. But in either location, youll be able to produce enough power to cover your energy needs and say goodbye to your utility billsif you live in an area that gets less peak sunlight hours, youll just need to have a larger solar array system installed at your home. Thus, production ratios differ according to geographic location and a lower production ratio means youll need more solar panels to get the amount of energy production you need.

How Much Power Am I Using
A kilowatt-hour is a basic unit of energy, which is equal to power times time . Your electric bills show how the average number of kWh you use per month.
For example, a 50 Watt light bulb left on for one hour would be 50 Watt hours, and 20 50 watt light bulbs running for one hour would be 1 kilowatt-hour . According to the U.S. Energy Information Administration, the average monthly electricity consumption for a residential utility customer is about 903 kWh per month.
Divide your average monthly usage by 30 days in a month to get your daily usage. If youre going by the national average, then you should be using about 30 kWh per day. Next, figure out the average amount of sunlight you get per day. The US ranges from about 4 hours 6 hours of sunlight per day, on average, see the below map. Lets estimate you get about five hours per day to generate that 30 kWh you use. So the kWh divided by the hours of sun equals the kW needed. Or, 30 kWh / 5 hours of sun = 6 kW of AC output needed to cover 100% of your energy usage.

How Many Solar Panels Do I Need For My Home
Its no use installing just one solar panelyoull need more than that to reap the financial benefits of a solar panel system. While the answer isnt always so simple, weve put together some example cases to help you understand, at a high level, how many solar panels you need to install an effective solar array.
Levelized Cost Of Electricity
| This section needs to be . Please help update this article to reflect recent events or newly available information. |
The PV industry has adopted levelized cost of electricity as the unit of cost. The electrical energy generated is sold in units of kilowatt-hours . As a rule of thumb, and depending on the local insolation, 1 watt-peak of installed solar PV capacity generates about 1 to 2 kWh of electricity per year. This corresponds to a capacity factor of around 10â20%. The product of the local cost of electricity and the insolation determines the break-even point for solar power. The International Conference on Solar Photovoltaic Investments, organized by EPIA, has estimated that PV systems will pay back their investors in 8 to 12 years. As a result, since 2006 it has been economical for investors to install photovoltaics for free in return for a long term power purchase agreement. Fifty percent of commercial systems in the United States were installed in this manner in 2007 and over 90% by 2009.
Shi Zhengrong has said that, as of 2012, unsubsidised solar power was already competitive with fossil fuels in India, Hawaii, Italy and Spain. He said “We are at a tipping point. No longer are renewable power sources like solar and wind a luxury of the rich. They are now starting to compete in the real world without subsidies”. “Solar power will be able to compete without subsidies against conventional power sources in half the world by 2015”.

Solar Panel Output Per Square Metre
The most popular domestic solar panel system is 4 kW. This has 16 panels, with each one:
- around 1.6 square metres in size
- rated to produce roughly 265 watts of power
To work out the output per square metre, use this formula:
Number of panels x Capacity of solar panel system
Capacity ÷ Total size of system
Example
- 16 panels of 265 W each:
- 16 x 265 = a capacity of 4,240 kW
- Total size of the system
- 4,240 ÷ 6 = 165 W per m2
