Today solar energy economics is developing more and more day by day due to the huge demand for alternative power. So if you want to decide which system is better for you, read on the article to find out all necessary information about grid-tie and off-grid systems.
Cost of Grid-Tie Systems
It is hard to estimate exactly what you'll pay for certain system. Prices and set-up costs usually vary depending on the availability of hardware, the level of local competition, and the difficulty of the set-up process.
But wait! That does not help at all, right? There are some basic rules used to calculate the total cost of the system. The price of solar panels has recently decreased due to the increase in worldwide production.
As a rule the price of solar power systems directly depends on its features. For example, if you want to install a 2,000-watt system at your home it will cost you between 16,000 - 18,000 dollars.
What Does This Amount Involve?
Let me explain it in the language of solar energy economics. Let's imagine the system runs about $4 - $4.50 / watt for the solar cells, wiring, mounting, inverter and other parts. Consider that panels themselves will cost up to $ 3.50 per watt.
Labor, equipment, insurance, licenses, overhead (offices, phones) and the income for the set-up contractor involves the rest amount: $ 4 - $5/watt.
It seems too much? In fact, it is really worth that, as the installation process of solar panel systems on roofs is difficult and even sometimes dangerous.
Cost of Off-grid Systems
These are even more complicated and therefore more expensive. For your note, off-grid system is able to run from 20-50% more compared to the Grid-Tie technologies. Here the budget number reaches up to 13-15 dollars per watt.
 Conclusion:
If the above-mentioned options offered by modern solar energy economics are too expensive for you, you can go for a cheaper way – build your own solar system using special kits.Â
