DIY Home Improvement

Melt With our economic situation and fluctuations in energy prices daily, many of us think of installing solar energy to help our energy needs of homes and reduce our electricity bills. But how many watt panel solar energy, we must say, halve our electricity bills? And how much power is going to cost to install? Here is a four step process that you engage these two crucial questions: 1 – Daily Power calculation: To answer this question after you receive your electricity bills last 12 months and calculate your kilowatt-hour on average (kWh ) usage per month. The reason we use is 12, because our energy consumption varies with the seasons. But if you do not have all your bills, just a month past. Then divide your monthly usage by 30 (the average number of days in a month to get your daily performance. – For example: If you have a monthly consumption of 800 kWh, then your total daily dose of 800/30 = 26 7. needs panel kWh per day. – Well, if you only half your electricity bill, then you must file 26. 7 / 2 = 13. 4 kWh of solar panel Watts per day. 2 – Calculate watts total Sun: To do this, you must first how many hours of employment in your area receives sunlight a day to be determined. It uses a map of the solar radiation is really useful – you can see one of our article Original on our website. Once you know your hours of sunshine per day, return to your daily needs kilowatt hours, and they participate in daily hours of sunshine, then multiplied by a factor taken into account 1. 25 (loss Power wiring Watt solar panel, battery and inverter) – Continuing our example, our solar panel must be equal to Watts: 13. 4 kWh / 5e 5h x 1. 25 = 3. 045 kilowatts or 3045 watts per day . In other words, we need to produce solar cells with a capacity of at least 3045 watts of power. 3 – Costing Watt Solar Panel: This step will help you develop, the cost of solar cells are needed to 3045 watts of power. Right now, the largest average cost of solar cells in the United States 4. $ 85 per watt. – In our example, it is the 3045 x 4 Costs. 85 = $ 14,768 to install solar panels to our electric bill in half. and, before the electrical wiring, charge controller, batteries, inverters, and electrical costs. 4 – offset the tax credits and refunds: Before the firearm and I think it will give us at least $ 14,768 for 3045 watt watt solar panel costs, we need tax incentives and rebates to take into account. With new funding for renewable energy tax will be in effect from 1 January 2009 and the state rebates alongside states like New York, Connecticut, New Jersey and California, the solar system costs are much lower than expected. – Consider this example: If we California, we would receive tax relief of more than 20% of the cost, and a federal tax credit of 40% for the rest. Thus, after rebates and credits, our solar panels would cost us $ 14,768 – $ 14,768 x (20%) – $ 14,768 x (1 to 20%) x 40% => $ 7089th As there are many factors that go into calculating your costs watts of solar panels, please only of Use our steps as a rough estimate. Some things have been impossible for us to bear into account, such as special offers by solar energy companies where they offer discounts on the full installation (including charge controllers , inverters, batteries, electrical tie-GRID, cost, etc..) Anyway, what you can see, it would cost about $ 7089 to buy enough solar panels to reduce by half our power account. We get it, but our solar cells at cost or open source, and the thread of our own solar cells, which saved us, is of course a lot of money. The good news is anyone can learn, inexpensive solar cells and find their own watt solar panels.
