They are less expensive than ever before and with all of the current rebates and incentives available for installing an alternative energy solution; they are more affordable than ever.
The key to picking the perfect system for your home is settling on a good solar power design that is flexible and can grow with your needs.
Older solar power systems were very rigid in their design and would have to be installed with a very specific number of solar panels, and in some cases these had to be a certain manufacturers as well to be compatible. This meant that homeowners had few choices in components since they all had to be perfectly matched as part of a solar panel design, which also made them more expensive.
One other problem was that the entire system had to be installed at one time and this made the initial investment quite substantial. For many homeowners this initial cost was prohibitive and prevented them from being able to install a solar power system entirely.
By choosing a solar power design that allows you to expand over time you can get your system installed for a minimal investment and then add to it each year as your budget allows. This gives you the ability to immediately start saving on your electrical bills and substantially increase those savings over time as you add more equipment to your system.
Another important aspect of solar power design is sizing the system correctly. For any solar power system to be able to supply all the power your home requires, you need to design your system to produce more power during the days than you are using. This extra power is sent back up the power lines to your local power utility where it generates a credit for you. This way in the evenings when your solar panels are inactive you can apply this credit against the power you need to buy back from the utility for your home. If your system is sized correctly, this back and forth exchange of power should cancel each other out and you’ll be left with a smaller bill each month.
The challenge in solar power design is to make your system just large enough to cover your power needs for the month but not too large as to generate an excess of power. In many areas the local power company will compensate you for this extra power and if that’s the case you may want to generate more electricity than you use and receive a check each month for the excess.
The concern is that many more communities limit the amount of power you can generate to the amount your home uses and any excess you send up the power lines is simply kept by the power company without compensation to you. In cases like this you have not done a great solar power design before installing your system and have actually spent more than you needed to for your equipment.
