How to calculate the amount of kilowatt hours (kWh) your solar panel system will produce


by Ranveer yadav

Interested to know how many kilowatt hours (kWh) your new solar panel system will kick out per year? It’s pretty simple to come up with a ballpark number. All you gotta do is look at the map below, which is labeled with an estimate of the number of kilowatt-hours (kWh) you can generate with one kilowatt (kW) of solar panels in every part of the India.
If you haven’t gotten solar yet and you want to skip the ballpark estimates and have a professional use their high-tech software to give you an more exact estimate, connect with one of our trusted solar installer partners today.
If you’re ready for the ballpark, multiply the size of your system in kW by the number that is written in the shaded region where you live in the map below. Then multiply the result by 78%, to account for losses due to wiring and conversion from DC to AC power. Simple!



For example, let’s say you live Delhi and are thinking about installing a 5-kW solar system. Most Delhi live in the North India, which is located in the shaded region labeled “2000”
Take that 2000 and multiply by the 5 kilowatts of your system size to get 10,000 kWh. Multiply that by .78 to get 7,800 kWh, which is a good estimate of how much electricity your 5-kW system will produce in a year.

How much money can you save with solar panels?

Ah, here’s the tricky part. Electricity costs different amounts depending on your utility company. To make it more complicated, some utility companies charge a flat fee for electricity, while some charge different prices based on the time of day or season.
Let’s look at a simple example, using the data from above. People in Delhi get their electricity from Electricity department , which currently offers a flat-rate of INR5.5/kWh for home customers.
Take the 7,800 solar kWh from the last step and multiply it by INR5.5/kWh, and you end up with INR42900 of savings per year. Pretty good!
You could further divide that INR42900 into 12 equal amounts to see that you’ll save an average of INR3575 per month. Note, that’s just an average, because solar panels don’t make the same amount of electricity all year round.
Unless you live at the equator, the angle of the sun in the sky changes based on the time of year. It’s low in the winter and high in the summer. Changes to weather patterns also affect how much sun your panels will get, though maybe not as much in the desert of Western India as in the Delhi.

How to estimate your own solar savings

Every state offers different electricity prices and incentives, and every roof is different, too. If you’re ready to bypass the guessing game using estimated numbers, get an actual solar quote for your home from trusted professional installers.

Top 10 Renewable Energy Sources

Image
Energy is an inevitable requirement where we want development to take place. All these power generation techniques can be described as renewable since they are not depleting any resources to create the energy. Renewable sources of energy are the ones which can be generated continuously in nature and are inexhaustible. These are the top 10 energy sources: 1.     Biomass-      Biomass or bio-energy, the energy from organic matter for thousands of years, ever since people started burning wood to cook food. Wood is still our largest biomass energy resource even today. Other sources of biomass can be used including plants, residues from agriculture or forestry and the organic components. Plants and animal matters are used for production of fibers chemicals or heat. The net emission of carbon dioxide will be zero as long as plants continue to be replenished for biomass energy purposes. Burning o...

5 Tips to Avoid Electrical Accidents

Image
Electrical wiring is everywhere, tucked behind the walls of your home and within your HD television, DVD player, laptop computer, printer, smartphone, security systems and other equipment. It only takes one electrical accident to deliver a lethal jolt to a human body, or burn a home to the ground. Copper Development Association (CDA) offers 5 tips to keep you and your property safe. 1. Reduce excessive attic temperatures: When you’re up in an attic on a sunny summer day, you know the meaning of hot. If the wires are buried in attic insulation, pass over light fixtures or, worst of all, are arranged in tight bundles, they become even hotter than if they’re out in the open. The heat doesn’t affect the copper conductors in the wiring; it’s the plastic insulation and jacketing that surrounds the wires that are the problem. These are usually rated to withstand up to 194 degrees. The cumulative effect of ambient heat and current on attic wiring can result in temperatures that come ...
