Why Arenx92t People Flocking to Solar Energy Generation?
01% of total energy demand.
However, demand for sustainable power generation has grown at a rate of 25% per year over the past decade.Compared with fossil fuel energy demand, fossil fuel demand is only 0-2% per annum.So why don\'t people flock to solar power?We think they are.
The biggest suppression factor for installing solar panels on the roof is actually the cost of doing so.More importantlyReturn period.If you can\'t recover the cost of installing solar panels in the first 12 months or less, then we think you should consider building your own solar panels.You will save money and shorten your return on investment.
The decision path is a simple five-step process.Step 1: how much energy do you need????Take out your nearest electricity bill.We recommend that you do so in the last 2 to 3 years to eliminate any changes in demand.
By recording the kilowatt hour (kwh) usage of each month, the monthly meter of electricity use is listed.If you also have separate hot water metering records.How much electricity do you use every year?What is the maximum amount used each year?What is the percentage of annual growth?If you decide to install solar, the amount of electricity you need is the amount of electricity you use during the biggest month of use this year.
Then the figure has increased on average over the past two years.This is the maximum amount you need.Step 2: Where/how is your power consumption????In order to figure out your solar demand, you need to understand where this energy consumption is.Calculate how many appliances you use often, how many watts they use at run time, and add extra power to use items you don\'t use often.
Look at the label on your appliance.
This will help you understand your usage and why?It will also determine the area or appliance you can save money by better using the appliance.On your device, you will see the number of watts used per device.For example, a washing machine can make hot water of 2000 watts.
This is 2 KW per hour.
To calculate the electricity bill for this device, multiply the kWh by 1 KW of the electricity bill.This is also very useful if the device has two operating modes to record the washing machine heating its own water and using cold water, or if the air conditioner is set to heating mode, it can also be cooled.Step 3: think about where to save electricity!We recommend that it be wise to identify areas where energy savings may be possible and to test if your savings are realistic, feasible, and can last for a period of time.
For example, your TVIf you turn it off with the remote control, it still uses about 20 watts.Even if you don\'t use it, your TV is actually wasting energy.And your computer.Use about 180 watts when the computer and monitor are on.
Computers are energy-efficient certified, which means they need the same energy to turn on as they normally use.So, your computer will turn it off if you don\'t use it ).Step 4: buy your solar panel technology!We strongly believe that building our own solar panels is a very cost-effective solution.
The starting point for buying solar panels or making them yourself is how much power you need, so, how many panels you need.If you have read the article, you will be very clear on how many kilowatt hours you may need.The rated power of the solar panel ranges from 1 W to 300 W.
Most solar panels up to 135 watts are 12 v dc (12vdc ).Most solar panels over 135 watts are 21 to 40 v dc.The Watt rating is the power generated by the panel in the full sun at 77 degrees Fahrenheit or 25 degrees Fahrenheit (amps x volts ).
This is the industry standard for all PV panel ratings.However, this is the \"best case\" scenario.In most places, when your solar panels run at peak efficiency, there is about 4 hours of peak sunlight per day.
But your panel will work 24 hours a day using various forms of light including stars, street lights and cloud conditions.As an average for the whole year, we have reduced the performance of solar panels by 10-15% of its maximum wattage rating.The real number you are interested in is the number of watts per dollar you pay.
By building your own solar panels, you can reduce the price per panel to £ 200 for $300.You don\'t need to tilt technically, the information pack available now is fantastic.You can make a 120 watt solar panel yourself for $240.
That\\\'s $ 0.
Power 50 per watt.
You actually need to reduce 120 to 15% Watts by 102 watts.That\\\'s $0.42per watt.If you buy a 120 watt solar panel from the Internet, you will pay about $1,100 for a device that is ready to be installed.That\\\'s $9.When you reduce efficiency by 15%, 30 watts per watt.
If we take the house on the right as an example, six solar panels generate 720 watts of power per second (during peak sun hours) will cost about $6600 and be enough for them to power.There are about 4 hours of sun peaks a day, but don\'t let it fool you.Even in the evening, the solar panels continue to work, absorbing tiny amounts of energy from the Starlight (or if you\'re in the city, the constant glow from the street lights), even in the winter, whenever.
(There are a lot of people who think that the solar panels completely stop working at night.Step 5: How much solar energy do I need?The energy of the Sun varies across the globe and depends heavily on weather conditions.We can expect to generate 1.2KW/m2 per hour, or provide 4095 BTU of electricity in case of sufficient sunlight at noon.
(1 kWh = 3412.
Let\'s say that your roof surface area is tilted South in the northern hemisphere and north in the southern hemisphere at 500 square feet or 48 m² square meters.Usually, the solar energy available for more than one year on the 1 m² roof is 16 KW hours.So, using the numbers above, we can expect to produce 48x1500 = 72,000 KW or 245,566,000 BTU.
If, like us, you use an average of 30 KW per day, you need an average of 75 square feet or a total of 7 square feet of electricity.5 m² solar panels.So you have it.We did our homework on solar panels.Check out our free newsletter on http:/www.Ubuild solarpanel
