In assessing the current cost of a home solar power system, one should not only consider overall total investment, but the overall system’s performance and ability to generate cash flows across its projected life-span.

2. Before undertaking a solar energy project, it is
good to find out the current cost of a home
solar power system. But you must also
understand how to calculate the return on
investment to consider the potential cost
savings down the road.
Figuring out exactly how much your solar system
will cost can be hard because electricity rates
vary, and each state or country has different
rebates that may affect the overall price of your
system. But you can simply inquire how much it
will cost to put solar panels on your roof.

3.  Currently, there’s enormous variation in the cost of
solar panels based on the type and efficiency of the
solar panels. But the type of panels used for
residential solar installations is standard and the
costs are basically set globally and they have fallen
within the past few years to almost half the price
they were in 2008 and about 100 times lower than
they were back in 1977.

4. Unless you provide a detailed description of the job at hand, such
as; the amount of wattage required, the type of installation
involved, the specific products you want and much more…You
cannot get an adequate estimate. This does not mean that
there are no reliable ways for you to determine the approximate
cost of the project you want to undertake, but it does mean that
generic estimates are often less than helpful.

5.  First of all, you need to calculate your solar panel
cost and return on investment by establishing
your payback period or the point at which your
savings equal the cost of your solar power
system and then bank your savings in energy
costs.
 In the calculation of your solar panel cost you
need to subtract tax credits from what you paid
for the system to come up with an accurate cost.

6.  examine the amount of sunlight in your area and the
position of your panels to determine how much energy
your solar panels is able to collect.

7.  You need to know how much you pay for your electricity bills by
dividing your total bill by the amount of hours of usage or
multiplying the number of hours on your bill by the kilowatt per
hour charge.
 If you are selling electricity you can also calculate the income of
a solar system by calculating the power it generates annually
and the SRECs you sell to generate.
 Calculate the return on investment by dividing the initial
investment into the yearly income to get a percentage of the
initial investment that is returned annually.

8. Studies show that an average solar homeowner will save
about $20,000 over 20 years from the solar power
system.
But again this depends your location’s climatic and morphological
conditions, as well as other personal circumstances.
Therefore in all different conditions you should be able to gather
comparable solar panel cost information in order to be able to
compare the different solutions.
There are other expensive equipments you will need such as
batteries and inverters. They are both expensive equipments that
certainly have an impact on solar panels efficiency and overall
performance of solar panels.

9.  The size of the project has a direct bearing on the per
watt price of the solar panels themselves. Large
projects, which require the system to provide over
5,000 watts of power, have a lower per watt cost than
small projects. According to a study funded in part by
the United States Department of Energy, solar energy
systems which provide more than 5,000 watts of
electrical power generally cost between $3.80 and
$4.40 per watt. Prices for this type of solar energy
system, however, were as little as $2.90 per watt, and
as much as $6.20 per watt.

11. The cost of solar panels is around $14,000 and it can take alm0st
4.71 years to get your money back and any energy savings
beyond this time frame represents your return on investment.
You can get 21% of your money back in the first year alone.

12.  The most valuable solution in getting the current
cost of a home solar power system includes all
factors mentioned here. However, the cost may
not necessarily be the one with lower initial
investment if it lasts longer enough to off-set its
extra cost or if it yields a higher output.
 If you are making a decision for your home solar
panels it may be a good idea to visit how much
does a solar panel cost and consult with a
certified solar panel installer for assistance and
professional advice.
