| Seems that everyone wants to know how solar electric adds up or calculates out and if it can make a profit for them. In most areas solar electric power is able to put some money back in your pocket. Some areas it will take a while. There are other benefits and financial gains from the use of solar energy and a Solar Electric battery backup system. How solar can help in more then one way is it can keep a pump running to keep water pumped out of an area that water would do damage to a valuable investment you have. So the pay back is three fold in this case. Because you are using the sun to provide electric power, you do not pay the city for the electric, you have electric power even when the city electric is down and you did not have to file an insurance claim on that valuable investment that would have gotten wet. And one more good thing is how solar kept your insurance rates from going up. Have you thought about how solar installed on your home will improve the re-sale value of your home. It tells the new buyer that they may never have an electric bill. If you have installed a grid tie system with battery backup. It would tell them they would not have to worry about missing work because of a power outage. Which is a money maker right there because if you are late or miss work it is just money lost and a bad rep with the boss. With the thought of how solar can help and you can profit from it, We are pulling together a group of utilities and programs and PDF files. With hopes to make it easier for everyone to see how solar can be to your advantage. And to help you understand how solar works. -------------------------------------------------------------------------------- For those of you that are thinking about going grid-tie. Here is a Performance Calculator for Grid-Connected PV Systems. It is a US Government website. There are two versions, this link goes to version #1. Page opens in a new window. Performance Calculator for Grid-Connected PV -------------------------------------------------------------------------------- The following is a link to DSIRE. This link takes you to a database of Incentives provided by each state in the USA. Just click on your state and find out if your state will pay for part of your new solar energy system. Opens in a new window. Dsire Solar Incentives -------------------------------------------------------------------------------- This is a Voltage Drop Caluclator. It is in MS Excel Format and will open in a new window. If you do not have Excel or a program that will open the file I would pass on by this one. However you can find an Excel clone program at download.com. This program will take a little time to study but is great for helping you save money by buying the correct size of wires. Over sized wires are just an added expence to you if not needed. And undersize wire will give you a voltage loss which means you waste solar power. Voltage Drop Calculator in Excel Format -------------------------------------------------------------------------------- This link is to an outside site but they have a nice Voltage Drop Calculator. It is not as flexible as the one above in Excel format but is a lot easier to use and don’t require you to have Excel on your computer. This link will open in a new window. Give it a try. Voltage Drop Calculator at CSG Network. -------------------------------------------------------------------------------- The following link is on the SunWize Solar website. It is a PDF file which is a great Solar Electric systems design guide. It has forms you can fill out to design your system. It as well has a Five Steps to Sizing a PV System approach. Not too hard to work your way through. It is 6 pages long. This link will open in a new window. SunWize Design a Solar Electric System -------------------------------------------------------------------------------- This link goes to Microsoft to their Terra Server. Just enter your Zip Code and it will give your Latitude to help you find what angle to set your solar array on for best performance. Opens in a new window. Terra Server, Find your Latitude -------------------------------------------------------------------------------- How solar can help you is really up to how you put it to use. |
