This is the average electric solar panel system purchased in the United States.
Most people who are interested in having a solar system on their home, want to make an impact in reducing their electric bill, and a 3.0 kilowatt to 4.0 kw PV solar system can do just that. If you are interested in earning all kinds of extra income
from a solar electric system, the chances are you would need quite a bit larger system than one which is only 3 to 4 kilowatts.
The exact amount of electricity that a solar panel system of this size is going to produce is going to depend on the usual factors for any solar system anywhere in the US. These factors are: 1) Sunlight hours, 2) Shading and 3) Orientation towards the sun. To a lesser extent, outside temperature will also affect the solar panels production of electrity, but that’s nothing to be too worried about.
Buying a solar panel system of this size is going to be eligible for at least a 30% federal tax credit, and probably other state and local solar incentives. What you should do is talk with the solar professional prior to agreeing on any prices and make sure the details of the incentives you are eligible for are written down in writing before you pay for the solar system.
Purchasing or Financing the Solar electric system:
Make sure to explore your options when it comes time to buy the system. For over a year now, there are many great state backed and federally backed financing programs for homeowners to purchase solar power systems. One of the main reasons is that these solar systems are looked at as a long term investment, and they add value to your home, so banks are more willing to loan money to homeowners because of that. Also, there is a instant generation of income or return on a solar investment which also make a loan for this more appealing to banks. There are several Green Banks, which specialize in loans for solar systems which you should investigate as well. These banks often know the process very well and make it much easier for homeowners to buy solar power systems. The solar professional you work with will also know about some good financing alternatives for you to help you get started.
