One of the things that puzzles a lot of people when Going solar is the cost involved and how it is calculated. Let's see if we can not solve the mystery especially here.
The reluctance of people to invest, which can, after all, a considerable sum of money on a new solar energy system, without knowing exactly where their money goes, it's perfectly understandable. Finally, the total cost of an average-sized solar plant in the range of $ 20-30000, before hisDiscounts, and this is a pretty hefty investment.
What should be remembered, however, that this is an investment for the next 20-30 years worth of electricity, and do not consider that a new system have been paid within 5-10 years of government. There is also an investment for the future of our planet and reduce carbon emissions from fossil fuels.
What is a "medium sized" system?
For the purposes of this discussion an average size for a family3 or 4 people in a house from 2 to 3.000 square meter is about 3 kilowatts. A 3-kilowatt system can handle up to 3,000 watts per day, which should be more than enough to power the electrical components and devices of more than medium-sized houses such as ours.
Distribution costs as a percentage
There may have been the allocation of the cost of a new solar power system secure enough to run numerous installations over the years by the solar industry. As mentioned above, the cost of a3kw system is about $ 2-30 depending on the selected components and their functions.
Here's the breakdown of the components and their cost as a percentage of the total as follows:
- Photovoltaic panels (currently costs about $ 4-7 per watt) = 60%
- Panel mounting, wiring and other electrical appliances, etc. = 15%
- Inverter = 10%
- Install = 15%

Solar panels are usually the most expensive part of a new system because of the complexity ofequipment and materials involved in their production. The cost of the panels has increased dramatically in recent years and will continue to do so, as technology improves, and a 200-watt panel costs about $ 1,000 per person, which would have 15 of these dishes at a price of $ 15 000 requirement means.
The cost, cable brackets, etc., depending on the type and angle of the roof, and if the system is mounted on the roof or mounted on the floor. The cost should$ 2 to 5,000, or about 15% of total costs.
An inverter is a complex device and comes with a variety of functions, which can increase costs, but for the purposes of our example, the cost will run $ 2 to 3.500 or 10% of the total.
Installation costs can change dramatically, so we would like to get quotes from several reputable suppliers as many as possible. But, as a general rule, you should expect to pay about 15% of the total system cost, which in this casewould be $ 3 to 4.500. At the same time, there is an element that we want to skimp on, because this is a great investment that will last at least for the next 30 years, so we should be careful, but to spend wisely.
Going solar is a key, and, perhaps, life, business and the planet-changing decision, and the facts as you can get, the more confident you can go ahead with your decision to go solar. I hope now to be aware of the costs and what you can and should expect to payfor the system as a whole and the parts that go to install such a system.
