One of the main reasons why there are a lot of people who disregard the idea of using the energy from the sun as source of electricity is because they are baffled about solar power cost. Some people say that it is expensive. Others would claim that the money is worth it. If you are thinking of having a solar power system in your house, you would want to be able to compute the actual amount, right?
It is true that the solar power cost will vary from one household to another because of several factors. Each family has different demands and needs when it comes to electricity. The type of system can vary from each household too. How do you know how much is solar power cost when it is used for your home?
Aspects Contributing to Solar Power Cost
When it comes to doing computations, there are major aspects that you have to take into consideration. First, is the total amount of expenses for the parts and components of the system. This includes the panels, wirings, battery, inverter and even the smallest clamp that you will use. Second, is the fee for installation. If you are setting everything up on your own then you need not worry about this. On the other hand, if you are seeking help from professional services, you would need to consider the service charge. Third is the price for building permits. In some locations, filing for such a permit is necessary before even starting to install the panels and other components.
Now, there are things that could lower those expenses. You have to deduct the amount that you will get if in case you filed for grant. The grant may not cover for all the expenses but it can significantly lower the amount you need to put out. Typically, there is also a 30% federal tax credit and other local tax rebates. Factor these in too. Once you have done your addition and subtraction, you would have a more concrete idea how much is the initial solar power cost.
Solar Power Cost for Panels
Getting the exact amount of solar power wattage that you need is important before you even start buying your materials. This will determine how many panels you would have to purchase and what type of system will work best for your home.
It is necessary to know first how much electricity your family consumes within a day. This will be your basis for computing the amount of solar power needed. Then refer to an insolation map so you could get the usable hours of sunlight that your location gets everyday.
The daily kilowatt per hour that your household consumes should be divided by the number of usable sunlight hours. Multiply the answer to 1.25 which is the value for energy loss within wirings, batteries and inverters. Once you know the wattage that the solar energy system should produce, you can then compute how many panels you need to install. The total solar energy needed should be divided depending on the wattage that each panel generates. When you know exactly how much panels to buy, you would not waste money on surplus panels and components.
Understanding basic solar power cost is not too complicated. You have to do the calculation before you start buying your materials so you would not waste your money on surplus panels and components. Get more information by clicking the link.
