Reduce Your Carbon Footprint
Since solar farms use renewable energy, they reduce the amount of carbon emissions in our environment.
On average, a solar farm can reduce carbon emissions by thousands of pounds per day.
This makes for a healthier and more sustainable planet that we can all share together.
Solar farms can save you money in the long run.
Many solar farms are able to generate half of their annual energy needs.
This means that they would only need to draw the other half from your local utility company, meaning youd be saving money on electricity bills every month!
Also, if your utility company offers a feed-in tariff, it means they will buy any extra energy you produce with solar panels and give you a credit on your electricity bill for this excess power.
The savings could then add up over time and give you a reason to install more panels in the future.
Solar Power Generation Choices
The broad selection of solar panel models available for household use are not created equal. And, they do not all generate the same amount of power.
Solar panels are rated based on the watts they generate. The higher the wattage rating, the greater amount of power your solar installation will produce. Most residential solar panels have power output ratings from 250 to 400 watts, depending on panel size and how well they convert sunlight into energy. While higher power ratings are considered preferable, power output is not the sole factor in judging a solar panels performance.
For instance, two solar panels may each have a 15% efficiency rating, yet the power output rating of one is 250 watts and the other is 300 watts.4 The higher output may simply be due to the 300 watt panels larger physical size–rather than having a high efficiency or more advanced technology. Therefore, panel efficiency is a better indicator of solar panel performance than just power output for meeting your energy needs.

Sir,Alternative energy, specially the solar energy is hype now a days but is it affordable for a middle class common man in India?The cost of initial installation of the system is very high and also one needs to replace the batteries every few years, say 3 to 5 years approx. The cost of a typical Tubular Battery, 150Ah/12V is around (Rs.12,000/- to 18,000/- and the captive power generated by one single battery will never be enough even for a middle class family of 4 to 6 people who uses average 3 fans, one TV and a small fridge, no Air Conditioner please.So every 3 to 5 years just to replace 2 numbers of batteries, it will incur a minimum expenditure of Rs. 30,000/- average, plus another few thousand extra expenses if the solar inverter goes bad.
Kindly enlighten me whether my views are correct or not. I need guidance.

How To Calculate Solar Panel Efficiency
Most solar panels have an efficiency rating of between 10% and 15%, which will usually be indicated by the manufacturer.
Efficiency also depends on the type of panel youre using , where your panel is facing, and much heat it is generating
The efficiency rating of a solar panel refers to its ability to convert sunlight into usable energy. So, if a panel has an efficiency rating of 15%, it will be able to harness 15% of the photons that hit it. Due to real-world conditions of weather and placement, a solar panel rarely produces its full wattage output rating.
To calculate the efficiency of your panel, youll need to look up the amount of sunlight that hits the earth in your particular area. Multiply this amount by the surface area of your panel, divide the maximum kWp of your panel by this number, and then multiply it by 100% to get an accurate efficiency rating.
Lets say 1,000-watts per square meter of sunlight is hitting your area, and you have a 1 square meter panel, youll end up with 1,000-watts exactly. If you have a 200 kWp panel, the efficiency will be roughly 20%

How To Understand All The Numbers And Symbols
Figuring out how much power youre going to get from your solar panel is actually a lot simpler than you might think.
Solar panels measure the power they collect from the sun inWatts . Typically, domestic solar panels produce a power output of between 250 and 400 Watts. Kilowatt is just another name for 1,000 Watts. We measure the energy a solar panel produces in Kilowatt Hours . So if you have a 250 W solar panel that gets the equivalent of four hours of direct sunlight a day, it produces 1 kWh of energy .
And then if you multiply your average daily power output by 365 , then you have your annual solar power output. In the example I used above, the yearly energy production would be 365 kWh.
Heres that calculation again:
Solar Panel Power in Kilowatts x Average Sunlight Hours Per Day x 365 = Annual Power in Kilowatt Hours
And thats it for the math.
The problem I have with all of this is that these numbers dont mean much to me until I translate them into actual energy usage. Why dont we take a look at what these Kilowatt Hours of energy mean to you and your electricity bill?

How Much Electricity Does One Solar Panel Produce
Before we start with the calculation lets get used to some basics terminology
- Watt and kilowatt are units of power. It basically shows the rate at which power is consumed by a device. For example a 100 watt TV will consumes power at a rate of 100 watts per hour. 1 kilowatt = 1000 watt.
- Kilowatt hour is the actual energy consumed by the device in an hour. For example a 100 watt TV running for 24 hours consumes 100 watt x 24 hours = 2400 watt hour or 2.4 kilowatt hour of electricity a.k.a 2.4 units of electricity.
For more detailed explanation check this article What is watt, kilowatt and unit of electricity?
On an average in India we receive 5 sun hours in a day so the total power generated by 1kW of solar is 1 kW x 5 hours = 5 kilowatt hour .
This is an ideal figure which considers uniform solar irradiance throughout the day, proper installation with best orientation, angle of tilt and no shadow impact on solar panels for 5 hours without any dust accumulation on surface.
If we calculate for ideal condition then average monthly power generation from solar panels will be 5 KWH X 30 Days = 150 KWH of electricity.
But not all days are equal some day we will get sunlight some day we wont, some days the panel will be clean and some days they wont be, hence we will assume 20% loss of power which gives us average daily generation for 1 kW solar panels to be 4 KWH of electricity and monthly generation to be 120 KWH of electricity.

How To Calculate How Many Solar Panels You Need
The formula we used to estimate the number of solar panels you need to power your home depends on three key factors: annual energy usage, panel wattage, and production ratios. What does that mean exactly? Here are the assumptions we made, and how we did our math:
Annual electricity usage: Your annual electricity usage is the amount of energy and electricity you use in your home over a full year. Measured in kilowatt-hours , this number is influenced by the appliances in your home that use electricity and how often you use them. Refrigerators, air conditioning units, small kitchen appliances, lights, chargers, and more all use electricity. According to the U.S. Energy Information Administration , the average American household uses 10,649 kWh of electricity per year, so well use that number as the ideal solar panel system or solar array size, which would mean you could offset 100 percent of your electricity usage and utility bill with solar panels . If youre interested in getting a more exact number based on your personal energy usage, check last years utility bills to find out how much electricity you used. Once you have that number, feel free to plug it into the equations below.
