How to calculate the costs and requirements Watt Solar Panel

With our current economic melt and energy prices fluctuate daily, we are Many think of the solar panel power to contribute to the energy needs of our homes, and reduce our electricity bills.

But how many watts of solar panel we need to say halve our electricity bills? And how will that cost us the power to install?

Here is a four step process you can follow to meet these two essential questions:

1 - Calculate Power Daily Used:

To do this, download your last 12 monthly electricity bills and calculate your average kilowatt hour (kWh) usage per month. The reason we use 12 is because our power consumption varies with the seasons. But if you do not have all your electricity bills, just use the one last month.

Then Divide your monthly consumption by 30 (the average number of days in a month to get your daily diet used.

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

- Now if you only want to halve your electricity bill then you need to produce 26.7 / 2 = 13.4 kWh of solar panel watts per day.

2 - Calculate Total Watt solar panel needs:

To do this, you must first determine how many hours of usable sunlight your area receives per day. This is a map of sunshine is very convenient - you can see one of our original article on our website.

Once you know your hours of sunlight per day, return to your kilowatt hours required per day and divide it by the sunlight every day hours, then multiply by a factor of 1.25 (taking into account energy losses wiring watt solar panel, battery and inverter)

- Continuing our example: Our watts solar panels equal need:

13.4 kWh / 5.5hrs x 1.25 = 3045 watts or 3.045 kilowatts per day.

This means that we have solar panels with a production capacity of at least 3045 watts of power.

3 - Costing Watt Solar Panel:

This step will help you work on the cost of solar panels needed to make 3045 watts of power. When the higher average cost for solar panels in the U.S. is $ 4.85 per watt.

- In our example: It cost us at most 3045 x 4.85 = $ 14,768 to install solar panels to reduce by half our electricity bill. And before wiring, charge controllers, batteries, inverters, and electrical costs.

4 - Offset Tax Credits and Refunds:

Before taking the gun and think it will cost at least $ 14.768 for 3045 watts watt solar panel, we need to tax incentives and discounts into account.

With the new energy tax revolving credit enter into force from January 1, 2009, and delivered state-side states like New York, Connecticut, New Jersey or California, our solar installation costs will be much lower than expected.

- Consider this example: If we were in California that we would receive refunds Tax about 20% of the cost, and a federal tax credit of 40% over the rest. Thus, after rebates and credits, our solar panels cost us:

$ 14,768 - $ 14,768 x (20%) - $ 14,768 x (1-20%) x 40% => $ 7089.

As there are many factors that come in calculating your watt solar panel charges, please use our steps only a rough estimate. Some things have been impossible for us to consider, such as special offers by solar installation companies, they offer discounts on the installation Full (Includes charge controller, inverter, battery, electrical grid costs and tie, etc.).

Anyway, what you can see that it would cost about $ 7,089 to buy enough solar panels to halve our electricity bill. We, on the contrary, either get our solar cells at cost or to get free, and the thread of our own solar panels, which obviously saved us a lot of money. The Good news is, anyone can learn to find cheap solar cells and make their own solar panel watt.
