solar panel cost-tips for investing in a PV system.

If you want to make the best use of your PV system then make sure that your PV modules must have a clear view of the sun for almost all of the day. Solar panel cost should be unobstructed by trees, roof cables, chimneys, buildings and other features of your home. If you cannot use your roof top then you can very well place your solar module on the ground either on a fixed mount or tracking mount that follows the sun to orient the PV modules.

The potential site for your PV solar system might be bright and sunny during certain times of the day and shaded during other times. The shading might substantially reduce the mount of electricity that the system can produce. In my opinion your PV system should be UN shaded during certain times of the year and this can be done with the creation of solar easement. Only your PV provider can help your to determine whether the site where you are going to install your system is really suitable for a solar electric system.

In reality the amount of space required for a PV system depends on the size of the system you have purchased. In general some residential systems require as little as 50 square feet and some other systems require 1,000 square feet. Now commercial systems are typically larger in size.

Now if your location limits the size of your system you might want to install a system that uses more efficient PV modules. At the end of the day greater efficiency means that the module needs less surface area to convert sunlight into a given amount of electric power.

Let me remind you that PV system modules are available in several ranges and types and some offer more efficiency per square foot than others. In general higher efficiency modules typically cost more and so you must discuss the system sizing with your PV provider.

So before investing in a PV system you need to determine what kind of roof you are having and what is its condition. Some types of roofs are simpler in nature and cheaper to work with. In general a PV system can be installed on any type of roof but typically roofs with composition shingles are the easiest to work with and those with slates are most difficult to work with.

However in any case an experienced solar installer will exactly know how to work on all types of system and can use roofing techniques that eliminates any possibility of leaks. You can very well ask your PV provider how the PV system affects your roof warranty. Let me offer you an important advice, if your roof is really older and really needs to be replaced in the near future then you can very well replace it at the time when the PV system is installed.

Only then you can avoid the cost of removing and reinstalling your PV system. Solar panel cost system can be integrated into the roof itself and for that you need to consider what portion of your current electricity needs you would like your PV system to meet.
