How to Calculate Cost-Watt Solar Panels

With our current economic melt down and fluctuating energy prices are daily, many of us thinking about the installation of solar cells to be able to contribute to the needs of energy in our homes and reduce our energy bills.

But how many Watts of solar panel power we need to say reduce our energy bills? and how much energy we will cost to install?

Here is a process in four steps you can take to respond to these two critical questions:

1 Calculate used Daily Power:

So, 12 monthly energy bills get their past and calculate the use of the average kilowatt hour (kWh) at the reason why we use 12 is because our energy consumption varies with the seasons of the year, but if you don’t have all your energy bills then mes.La simply use one last month.

Next, divide your monthly usage by 30 (the average number of days in a month, to get their daily food used.)

-For example: If you have a monthly consumption of 800 kWh, then your daily amount is 800/30 = 26.7 kWh per day.

-Now if you want only halved its invoice energy, then, needs to produce 26.7 / 2 = 13.4 kWh Watts of solar energy per day.

 

2 Calculating Watts of total solar panel needs:

To do this, you must first determine how many usable hours of sunlight area receives a day.This is where a map of solar insolation is useful – you may see one of our original article on our website.

Once you know your hours of direct sunlight daily, return to your daily kilowatt hours required and divide it by the daily sunshine hours, then multiply by a factor of 1.25 (takes into account energy losses from wiring Watts of solar panels, a battery and an investor)

-Continue from our example: our-watt solar panel requires equality:

13.4 kWh / 5.5hrs x 1.25 = 3.045 kW or 3045 Watts per day.

This means we need solar panels with the ability to produce at least 3045 Watts of power.

 

3 Calculate the costs of Watts of solar panel:

This step will help you find out the cost of solar panels that are needed to make 3045 Watts of power.By far the highest average cost for solar panels in the United States is $ 4.85 per Watt.

-In our example: IT will cost us at most 3045 x 4.85 = $ 14,768 to install drivers of load, batteries, investors and the costs of electrician solar panels to half of our energía.Y that before of cabling, Bill.

 

4. The diversion of rebates and tax credits:

Of jumping the gun and I believe that we will cost at least $ 14,768 for 3045 Watt Watts of solar panels, we need to take the account of tax incentives and rebates.

With the new renewable energy tax credits go into effect on January 1, 2009 and redemptions of side of the State as New York, New Jersey or California, our solar installation costs will be much lower than expected.

-We use our example: If we were in California would receive around 20% of the cost and 40% of the resto.Así that after rebates and credits, our solar panels cost federal tax credit tax refunds we:

$ 14,768-$ 14,768 x (20%)-$ 14,768 x (1-20%) x 40% => $ 7,089.

Since there are many factors to calculate your costs-watt solar panel, just use our steps as an aproximada.Algunas estimate things were impossible for us to take into account, such as special offers by the solar installation, companies which offer discounts on the full installation (including driver charge, inverter, battery, costs of electrician tie grid, etc.).

Anyway, from what you can see that you cost us about $ 7,089 to buy enough solar panels to half of our Bill of energía.Nosotros, instead, either obtain our solar cells without cost or them free source and connect our own solar panels, which obviously we saved much dinero.La good news is that anyone can learn how to find inexpensive solar cells and make your own power Watts of solar panels.
